I too am building a C-19 using primarily Dave Conway's castings.
Unfortuneately, I started several years ago before I met Dave, and started using Milner drawings. Not knowing any better, I had Roger's-Cooke make me a set of frames for the Milner engine. Then, too late, I discovered Conway. So, after a LOT of welding and milling I had the frames modified 'bout as close to Conway dimensions as I could get them. Anyway, since this project has dragged out for more years than I care to count due to the demand of my business and delivering other engines to buyers, I have spent a good deal of time trying to ferret out every possible supplier of parts suitable for this engine. The only thing I have come up with for domes is John Braun's castings for his C-16. I have a set of these and they aren't TOO bad. Have no idea what he sells them for now. These domes are complete and cast in 1 piece. At worst, when it comes time to use them (assuming Dave doesn't have any at that time) the tops can be machined off and just use the bases and fabricate the balance.

I haven't looked at Daves Mogul castings...does he have the dome bottoms for this engine?
Can they be used?
Rudy do you know since you built one of Dave's Moguls?

My responce rom them;

Thankyou for the enquiry regarding the Shay locomotive that I have recently had on display on the IBLS tour in the USA.

We manufacture finished locomotives to order.
We do not normally supply drawings or kits.
A finished Shay locomotive takes us around 4000 hours to build.
We normally complete one at our works in 10/12 months from reciept of the confirmed order.

Details are as follows -
Scale 3.3/4" to the foot
Track Gauge 7.25 or 7.5" (LH wheels are on splines)
Length 10 feet, Width over cab 28" Height over stack 33"
Weight 1600 pounds full of water - Firing - Propane 6 pounds per hour.
Normal operating speed around 4 - 6 MPH Max speed 12 MPH on good track.
Hauling capacity -40/50 adults on 15 passenger ride cars on 2% grades.
All shafts/ axles/ crankshaft etc run on roller or ball bearings.
Wheels are machined from 1045 med tensile steel for long flange life.

Costs ex our factory in Auckland New Zealand US$ 110000.00
Freight to the west coast of the USA aprox US$ 4000.00

We would crate the locomotive for shipping and also fly to your site and give you the necessary operator training when the locomotive arrives.

Delivery - The Shay 'ENTERPRISE #4' you have seen on the web site will be available for sale in about six months time - ie April 2001.

The ENTERPRISE has just spent the past month running at tracks around Canada and the USA.

You are welcome to visit NZ and trial run it if you wish. The next major run it will be operating is at the Havelock North miniature railway which is about 6 hrs drive south east of Auckland NZ.
The dates are October 27,28,29,30. We can of course run it at our 1.5 mile track in Auckland at any time that would suit you to visit.

If you require further information on this locomotive please contact me further and I will be happy to assist.

Thanks for your enquiry and I look forward to your reply,

Well, I certainly did roust a few from the rafters.
We managed to get a good part of a pile bridge done Sunday, after an unexpected run to a few stores for lumber and a table saw.
Then after we got back we had to finish digging the pads for the bents. We used 4" dia PT fence posts for piles, 2' long, since the bridge is only 8' long. 2 vertical posts and 2 battered 2 in 12 with a 4" by 4" cap. We're using 2 sets of 2 2x6's for stringers, and attempted a "bridge" look by sawing 1.5" x 2" ties laid on their side on 3" ctrs. I'm sure they're undersize, they'll do until we find actual dimensions. We slathered on a coating of creosote/roofing tar/ #2 fuel oil to give it a bug-resistant coat. Most of this sunburns away pretty quick.
My friend's letter with his order was returned undeliverable today, he was bummed out because he wouldn't be calling in to his boss about "rail flu". Hopefully he's got that address correct now.
I guess that will give us a week to saw up some ties. We hope to get them pressure treated (creosote), but I'm not sure those Maine 2-footers had the extra money to treat the ties. Most of the 2-footers were gone by the 30's, and with so many good types of hardwood available back east I can almost see them going with untreated. That would be tough to simulate here, smaller pieces of wood here compost rather quickly.
Yes, Cam, I always type the same way as you, only I use my elbows.
When I try to use a spell check many times it has no idea of what I wanted to say. So if I don't try to proof read, I usually send a cryptic-looking message appropriate for CNC programming.
This one previous message in the group about a fireworks plant explosion- How sad! It is my hope that groups such as this would choose to share as much information as possible. "Unfortunate" circumstances are the greatest enemy to people like us- many were raised in the diesel age, and many are clueless on where to start, and how to do it when they get started. Many steamers have passed on, taking with them their knowledge. From coffee spills to fireworks plant explosions, our heritage slips away bit by bit.
I have been eyeing the RMI catalog and web page for a while now.
I have not been made aware of a loco from them based on the Stuart with a longer wheelbase. This, however, seems like a starting point.
I'll email them for additional info.
I can't afford to start a loco, but I also can't afford to wait until I ain't got the energy to do this stuff. Since I probably won't be modeling all of Sandy River's locos, I'll buy most parts machined. My friend works in a machine shop and is trying to sweet-talk the programmer into doing a program to finish wheel castings. He's ordreing an RMI axle-wheelset, and a couple rough cast wheels to see what machine will work best. A year ago they had one CNC lathe sitting quite idle. Now they have four going full-time. I just hope his boss doesn't suggest the machine with the fritzy tool-changer.
You might finish a wheel with a foot treadle and a nail file quicker.
That shop is so busy we will be LUCKY to get a machine open.
He is ordering 1" high aluminum rail from Real Trains in Yucaipa, CA., from a web page ad. I hope this rail will work O.K.
I better get my tiny bit of shop space ready...

Has anyone used the following 24V DC motors in an electric engine? I'm in the process of gathering what I need to build one and I just want to make sure they're as powerful as claimed. They are rated at 1 HP which should be plenty enough power for the engine and a riding car.

I can't find any other decent source for a low cost motor. I don't want to spend $250-$350 for a commercial unit. I did find a surplus site but they were sold out.

Subject: More details on DC Motors



Sorry for the lack of detail.

I want to build a model of an Alan Keef two foot gauge critter. Two axles, ugly cute. I'd like it to be 24 volts with one or two motors. If I can find one motor that is strong enough I'll use it and chain drive the second axle like the prototype. I don't need much power, I don't plan on pulling more than one car behind it with maybe 600 lbs. Our largest grades at PVLS will be around 1.5% with our new expansion.

I'll reduce the RPMs via chain drive to give me a top speed of around 8 MPH which is a touch faster than the club allows. My controller will handle 35 amps continuous and 50 amps peak. It supports regenerative braking and a magnetic brake output.

I've heard of guys using everything from commercial units to fan and wiper motors. I am open to any and all suggestions. My big problem is I'm not motor savvy when it comes to figuring out exactly what size I need. I know that 1 HP is overkill but I don't want to come up short on power either.

Most of the motors I've found don't even show a HP rating. They show torque rating in ounce/inches! This is greek to me. I'd LOVE to have a simple "hey Stan you need to look for this size motor(s)" from someone.
Thanks for all those who have responded. When I'm done building the engine I'll post the details. My goal is LOW cost but I still want a good running engine.

Well, 24v at about 23amps is 3/4 hp. So if you can get one motor rated at that, that would do. But I think it would be easier to find two motors, 24v at 12a, which is 288 watts or 0.38 hp. Even one of these would probably be plenty as you are going to gear it down quite a bit.

I've been doing similar calcs on building an electric engine here in the UK - I'm electrical engineer in automation by trade, so the calcs aren't a problem (though I think in Nm, kgs etc, which would make them pretty much unintelligible to most people in the US, I guess). I'm starting at the other end, with the tractive effort I'd like the engine to have, and then working back up through the transmission/motor/control system to get that output at the speed I want.

Question I have is this. What is the typical rolling resistance for 7.25/7.5 in gauge stock on the level (gradients are easily calculated)? I've always seen a figure of something like 10lb/ton quoted for full-size railways, but I imagine it should be higher on smaller scale equipment. Is 20lb/ton safe? Too high? Does it change significantly for different wheel/rail material combinations - steel/stainless/aluminium/brass?

I've worked out a thumbnail of 60lb te plus being sufficent to haul a couple or three cars with a dozen passengers on around any reasonably level circuit (gradients less that 2.5-3%). Is this remotely right? (At 8mph, this te works out as a power just over 1kW, or about 1.3 (metric) hp - from earlier postings looks as though I might be over-estimating things a bit, but the gradients are on the steep side).

(This would be for a 4 axle G8/12, so I'd need some haulage capacity)

Suggest you go to C&H Sales Web site .

They are located in the city of Pasadena, CA and get lots of stuff from JPL and CalTech. They have a large assortment of DC motors at very good prices, but if you find one that suits I suggest that you buy it fast and buy as many as you think you will ever need 'cause as you've already found out, once gone, gone forever!

BTW: C&H is also a great source of all kinds of valves, gauges, high pressure flex tubing/pipe, bearings, etc. There is hardly a live steamer in the LA area that doesn't have some of their stuff on his engine!

1) Does anyone know what colors the Billerica & Bedford cars were? I can't find it in my notes or books.

2) I'm interested in building some peat cars to pull behind my battery engine and the prototypes were unsprung. Does anyone run unsprung, two axle cars? I'm concerned about derailing more than anything else.

3) If anyone has plans for such a car, even a simple sketch I'd appreciate a copy. I have a few photos from the net of cars being pulled in England.

4) OK, don't flame me on this one - I had a chat with a member of another club at our blow-down about modelling two footers out of scale. The problem I have is my club's track has some spots where a 3.625" scale boxcar would have some problems. The car would be about 24" wide and 7'7" long. My thought was to build them to 3" scale which would make them a more reasonable 18.3" wide and 6' 3" long. Any thoughts on this idea? This has been done in Gauge one and it still preserves the "look" of the equipment but makes it fit in with the smaller scale stuff.

Best example I can think of was when Don Young designed Lucky 7 (the Bridgton and Harrison engine). As an outside frame engine, it was 3.75" scale. As an inside frame, the gage was the same but the scale was considerably smaller. It still had all the appeal of the B&H. --Denis Larrick

Stan,
We tried a four wheel ballast car because it is easier for one person to re-rail (a special L shaped tool fit in the coupler pocket and used the track for the fulcrum as a first class lever to pick up one end of the car. Once one end of the car was in the air, that end could be pivoted laterally to find the track. That lever also was used as a handle for the 0-2-0 pulling the car). The axles were sprung and ran great with a load, but followed the track only out of idle curiosity when empty. Then I saw that Baldwin used concentric springs on the rear truck of some tenders. Tenders were notorious for tracking problems because they were either heavy or light only on one end, so the three legged milk stool effect was destroyed in one condition or the other. The inner spring was longer and flexible under light loads. With heavy loads, it compressed all the way and the car rode on the shorter outer springs which were beefy. It worked !!! My rule of thumb is to compress a spring to half its compressible length under load (halfway between full length and compressed length). In this case, the inner would be at that point when the car is empty, and the outer would be at that point when the car is full. Of course, without careful choice of spring length, the inner could bottom out before outer gets to this point.
I would recommend also posing this question to our European friends who have much more experience with two axle stock. A friend of mine is building an engine with a two WHEEL (one axle) tender. Can't wait to see how that works !!

Subject: Re: Motor Torque



Power = Torque x (Rated)Speed

If the rated speeds are equal, then torque will track up and down with power, otherwise not.

With your two motors above it looks as though you can expect the 1HP motor to run at about 4 times the speed of the 1/3rd HP. (About 3000 and 700 rpm respectively)

Obviously, you could gear the 1 HP motor down so that the output speed of the gearbox was about 700rpm - you'd then expect perhaps 1400 oz.in, less gearing losses. (Incidently oz.in are units of torque, not to be confused with oz/in, applicable to spring rates)

However, since one of the more difficult (and expensive) items is going to be the actual transmission, and the higher a gear ratio you need the more so it becomes, I'd be inclined to go for the 1/3HP unit and use more than one of them if you need the Te.

(to get 8mph with 6 inch wheels from a 700rpm motor, you need to gear down by about 1.55:1, easily down with chain sprockets, timing belts etc. If you start with the 3000rpm unit, you need a gear ratio of over 6:1, too much for single stage of chain, so then you need idler shafts etc.. - I don't know what size wheels you're using, but 6in seems a likely size)

Hi Denis, Tom, and Stan

What Don Young did was to design the model as 1.75" scale to run on 3.5" gauge track. Then for 7+ gauge track he moved the wheels outside the frame and created a STANDARD gauge engine still in the 1.75" scale. This was acceptable for the English market but not for the American one. So he designed a 3.75" scale model for 7+" gauge.

Yes, the Late Don Young's Mini Lucky 7 1.75" scale locomotive is greater than our normal 1.5" but because of the size of the two footer, it is still a small locomotive. I know, I built one. For people running on a small track, without significant grades, it is a very good locomotive for the "American one." Lots of detail and it looks great. However, it is an excellent running locomotive but because of its relative light weight and small water reserve I rather run my 2 1/2" Lil Lima.

Build to the average width of the foot pegs most use and then keep your feet inside the engine or tender. Twenty one inches worked fine for me. About 35 inches for height looks visually pleasing but even higher if the prototype calls for it.

Stan - Don't waste time & money on springs, you don't need 'em. Equalized three point suspension will take care of your problem, since you have a stable situation either loaded or unloaded (the previous mention of tenders is a special case where fluid "slosh" creates special conditions.

Simply make one axle rigid to the frame, and fix the other axle so that it can pivot in the center.

I have a few drawings of 2' gauge cars, I will look and see if one is a peat car; I think mostly I have flats, gons, boxes and cabeese.

Most British models I have seen use manually opened cylinder drain cocks.

These work a snifting valves when the throttle is closed. Actual snifting valves allow for vacuum relief when the throttle is closed without having to open the drain cocks manually.

I do not know if drifting and snifting valves are only a question of semantics or if one or the other is upstream or downstream of the throttle. Arno

Never thought about this aspect of automatic drain cocks..... I probably wouldn't trust them for this function. My Chloe locomotive has drifting clack valves on the front of the steam chests. I also have automatic drain cocks - but with a teflon diaphram not a ball.

On the Schools class 3-cyl engine I am building, I have snifting valves as per the prototype located on the smokebox. This will feed into the dry header (after the superheater) once I decide how to pipe them in. The drain cocks are automatic and are of the piston/shuttle type.

Actual snifting valves allow for vacuum relief when the throttle is closed without having to open the drain cocks manually.

True, and this is to prevent ashes from a coal fired locomotive from being sucked down into the cylinders through the blast pipe.

I do not know if drifting and snifting valves are only a question of semantics or if one or the other is upstream or downstream of the throttle.

Semantics----

I wonder if drifting valves are really needed on a locomotive that doesn't produce ash? Propane fired locos wouldn't seem to need them. I think oil fired locos would need them since the stack exhaust is pretty dirty and contains particulates.

Somewhere in the steam circuit, there has to be a method of "breaking the vacuum" when a locomotive is drifting with the throttle shut. The purpose is to prevent ashes, etc. from being drawn back down the exhaust stand by the vacuum in the cylinders.

Baldwin, in their 1896 parts catalog, called their valves "Vacuum Relief Valves". Most American slide valve engines had the relief valves at the front of the steamchest. They are an angle fitting, usually in line with the valve rod. Piston valve locos usually had them either on the valve chest heads or directly tapped into the steam passages. The Pennsylvania Railroad had a very destinctive valve at the base of the branch pipe connection to the valve chests. The valves are sometimes called "Drifting Valves", though that more correctly refers to a position of the throttle that allowed a small amount of steam to enter the dry pipe when the main throttle was closed. On the Riverside & Great Northern, I used to drift with about 5 psi of steamchest pressure (we had a gauge), because I didn't think that our relief valve was big enough.

When you open the throttle on a slide valve loco, the "snifting" valves on the steamchest blow a puff of steam, then snap shut with a "pop". When you're drifting down the track, you can hear them sucking in air.

The British generally mounted their snifting valves directly on the dry pipe, or the branch pipes, at the top of the smokebox. They would be out of the dirt up there, and the theory was they would suck in cleaner, cooler air.

I hope this helps.

Does anyone know anything about a "Witherill Air Brake". I inherited an air pump, bigger that 1.5" scale but on the small side for 2.5" scale that has a brass plaque on the side with that name on it and a capital "W" inside a circle logo.

The plaque is pretty crude, appears to be hand stamped. The pump body is cast iron and looks very good, and the workmanship is also good. The pump appears to have been run quite a bot with pretty obvious wear marks, and I got is in a partially disassembled state as though someone were preparing to repair it or trying to figure out what was wrong with it.

Hi Jerry:

According to my 1954 edition of "Locomotive Management", by J. S. Hodgson & C. S. Lake, The Tothill Press, Westminster, S.W.1, the proper location of the vacuum relief valves on a superheater header is ahead of the superheaters. One purpose of the relief valves is to admit cool air to the superheaters, to prevent them from burning out when drifting with the throttle closed. There's a drawing of a superheater relief valve used by the Southern Railway, possibly on your "Schools" class loco, on page 269.

Stan,

You might take a look at the 30" gage 2-4-0 tender engines built for Tokyo Disneyland (photos and drawing in Michael Broggie's "Walt Disney's Railroad Story"). These were patterned after Disneyland #4 "Ernest Marsh" which was patterned after D&RG "Montazuma", though heavier (I once thought of building a 2.5" scale #4). In 3" scale, the gage would be 7.5" and it would be a fairly beefy engine with all the weight on the drivers and a tender that you could build with plenty of water space. It probably would be wide enough in 3" to get your feet in the cab. And I would think that you could adapt Wato or Roll Models castings to build it. It could be built with either Stephenson or the simpler Hackworth. Note that the Tokyo engines were designed aesthetically in America but were engineered mechanically and built in Japan. For some reason, the Japanese reversed the sand and steam domes. Sure looks funny with the sand pipe coming from the rear !! That's my two cents worth, anyhow.

For my engine, I made an open topped brass fitting that looks like an old fashioned oil cup on top of the steamchest. The bottom of the cup is tapped for 1/8" pipe and has a knife edged hole above the thread. A 1/8" close nipple connects the cup and steamchest head. The nipple has a piece of coathanger wire crosswise through it to keep a ball from dropping into the steamchest. When running, the ball is blown up against the knife edge to seal it off steamtight. When drifting, the ball drops and breaks the vacuum. When sitting, the ball drops and I can give the cylinders a manual cup full of oil (also at the end of the day). If I start up before all the oil drains down, I get a nicely weathered smokebox. It has been very practical, especially when my mechanical lubricator isn't working well. I plan to make a top for it to keep soot from getting in and lapping my valves.

Well I managed to do it. There is a picture of the infamous "Marie's Goose" in the files section. (And above)

For those who are interested, I'm either blessed or cursed, depending on your perspective with a wife who loves to run trains! Marie's first thought was that she wanted a Mason Bogie, as that is her favorite steam loco. But after some reflection she decided that she didn't want anything that complicated. The end result is that the #2 Galloping Goose was her next choice.

As you can see in the photo it's not quite totally finished. still need to get the headlights and a few other small details done. It is powered by a 24 volt motor located in the hood area with a drive shaft to the rear truck. The front axle of the rear truck has a 1/1 right angle gearbox and the rear wheels are chain driven the same as the prototype. Two 12 volt deep cycle batteries supply the juice, and it will run for about 6 hours at Train Mountain on a charge.

Which way do I go? In the process of laying track I have come to a frog. I am building a bolted rigid design which should pass for a 2' gauge frog, but if I set the wing rails at anything near the 1 1/2" scale standard, it no longer appears to be a 2-foot gauge frog. In 3 3/4" scale I reckon my gap to be around .6", and setting the rails up that way is really convincing. But if we adhere to 1 1/2" scale standard to have access to more clubs, I can't have so wide a gap. Frustration.
I have seen the IBLS Standards for wheels in 1 1/2" scale, I really need to know what the flange gap through frogs is supposed to be. And which scale flange profile do I use for 3 3/4" scale to be run on 1 1/2" scale track?
We'll be ordering wheels soon, it looks like a cobbled-up version of swing motion trucks with dimensions of Sandy River trucks will be used until a source of castings for journals, etc. can be found.

This all in a sneaky attemt to build a loco that will be comfortable on both 7 1/4" and 7 1/2" track. And not mess up the track so that the track owner(s) catch you in this perfideous act.

Stan -

I have posted a file titled LMB001.Rev. B.tif; you might want to take a look at it.

We use this flange profile at JT&S on our 2.5" scale 7.5" gauge track. It meets any club's IBLS standards gauge but exhibits superior rolling qualities to the IBLS standard and does far less damage to the rail on tight radius curves. It also appears to cause the wheels to wear better and the flanges to stand up longer.

It was developed by Lorin Brown and is basically a scale down of the flange profile used by the prototype. If you intend to operate on 7.5" gauge 1.5" scale layouts you will need to meet their (often) IBLS standards.

Good luck, and if you do decide to use the profile, I will be interested in hearing how you feel it works for you. Incidentally, Como Roundhouse Products sells a flange cutting tool that cuts this profile in one plunge cut to a prepared wheel.

Subject: Re: Digest Number 158



To Stan Rutledge:

We inherited some bolted frogs with a batch of track we bought from a defunct club. As default switch builder, I deferred using them on our new turnouts 'till all the cast frogs with the "built in" ?frog guard rails? were gone. After eight years on the ground, I can attest to the fact that this bunch, at least, has not given a moment's trouble. I assume as a "newbie" that by "bolted frogs," you mean a cast frog with the "inner" guard rails formed from the incoming closure rails, which are bolted to the frog casting using spacers. I expect that you could use also pieces of rail bolted together, in place of the cast frog piece too, if you machined them carefully and provided a triangular spacer. For my own peace of mind, I'd tack weld the point area on the bottom where it's out of sight, at least.
A few point that have recently been bugging me are:
1. What is a 75 foot radius switch? Is it one with a 75 ft radius from the points to the end of the curved stock rail?
2. If so, what is done about the tangent section of that rail, as it parallels the frog? I have always used a 24" long tangent, centered on the frog point, but don't have any authority to cite.
3. Officially, is the curved stock rail, as it runs along the points a curve, or is it straight. Our design uses a sharp kink just before the point (gives the point a plaace to hide), then runs straight (diverging) for the length of the point, to a spread that gives clearance between the two rails, then commences its 75' Rad. curve so that it comes tangent 12 inches before the frog point. Beyond the tangent at the frog, it resumes 75 foot raadius. (In case it's not obvious, we aare expanding our yard with 75 ft switches!) Any observations appreciated.

To those of you with the 7-1/4 - 7-1/2 gauge problem, (and I do sympathize with you). How in Tunket do you plan to finesse the back to back problem with wheels for dual gauge? Just an academic question.

Subject: Re: Switches/Digest Number 158



Hi Howard:

Full size mainline (even narrow gauge) switches aren't described by their radii, but by the "angle" of the frog, 1:4, 1:6, 1:20, etc. The only ones I know of that are, are portable track switches, used in mining, etc., that came in 15, 20 and 30-foot radii. On the portable switches, everything is curved, from the toe of the point to the toe of the frog. The only curve in a "regular" switch is between the heel of the switch point and the toe of the frog. As you say, the diverging rail is straight from the "kink" for the toe of the point to the heel of the point, and straight again alongside the frog. I don't know how long your switches are, but 24" of tangent doesn't sound unreasonable.

Another thing about the points is their height. On the CB&Q standard switch point, the toe of the point is planed down 1" for 12". Then, the beginning of the point sits on thicker slide plates that lift the top of the point about 1/2 inch above the stock rail. The nose of the point is still below the top of the stock rail, but as the wheel moves down the point toward the frog, the tread rides up on the point rail so that the wheel isn't sliding sideways on the stock rail as the point diverges. The slide plates taper off, so that by the heel of the point, the rails are level.

BTW, track speed through a turnout is generally determined by the length of the points. We have 25, 35 and 50 MPH power switches (the hand throws are all 10MPH) out here in the Powder River Basin, and even at their rated speed, heading in is a rough ride. The points on the 50MPH turnouts are so long they have two sets of throw bars. Some of the switches at the bottom of hills have the points bent into a reverse curve! When you come downhill with 20,000 tons of train in full dynamic brake and air set, something has to give, and it's generally the points. The welders spend a lot of their time building up the points of the frogs, too.

This is a semi-commercial post, I apologize but I may be able to help some folks save a bit on wheels. I don't make parts, I'm just negotiating a deal with someone who does.

I'm about to place my order for 6 1/4" wheels. They have an IBLS flange, 3/4" axle hole, 1" tread. They're CNC machined steel with a black oxide finish. If anyone is interested here are the costs:

Here are the prices for the wheels:

8 Wheels - $27.20 Each
16 Wheels - $21.00 Each
32 Wheels - $17.75 Each

Broaching will be an additional $5.00 per wheel.

Axles made from CRS stock would run about $13.00 Each with black oxide finish (not including keyways).

Shipping cost is extra, they ship from Euclid, OH, 44132. I ran the shipping charges for a few folks around the country from the UPS web page. I will see if I can find a cheaper method to ship. Here are the rates:

StateUPS per 8 Packing
CA41.06$7.00
TX, SD35.33$7.00
MA32.58$7.00


If we can get a big enough order I can reduce the price by about $2 per wheel. I'm ordering 64 based on the responses so far, that's all I can afford to pay for. The next price break is at 128.

The axles will extend 1 3/4" beyond the wheels and maintain the 3/4" size of the wheels. This will allow the use of standard bearings. I have only received one request for axles so far so I can't get a quantity discount.

Please contact me off-list ASAP if you are interested.

Hi Stan:

You can put the wing rails anywhere you want them. The IBLS "standards" are set up for 1-1/2" scale models of standard gauge equipment. The worst thing that will happen with a wide spacing is that the wheels might drop down into the gap a little when the tread passes from the wing rail to the point of the frog. In the long run, it's not something you want to happen, because it's hard on the point of the frog, but with a wide tread (that is, wider than 1-1/2" scale), as your 3-3/4" scale wheels will probably have, it shouldn't be anything to worry about. The important dimension is the guard rail-to-point of frog, also known as the "check gauge". All that really has to happen is that the guard rail keeps the flange from picking the point of the frog. Your "track" standard has nothing to do with your being able to run on someone else' track. As long as your wheels are set up to something close to the IBLS standards, they should fit most people's track, and as long as your check gauge is within a reasonable tolerance of the IBLS standard, anyone else should be able to run on yours.

Best,

Mike Decker

I've just started in this small live steam. I work up on the worth valley branch on a weekend. i'm looking for a small 3 1/2" gauge loco a 0-6-0 or something of the like ( built up in running condition).
can any one tell me any web sites with these on.

Andy; There is probably a lot of sites that have what your looking for but heres a couple of places you could go to get started. The first one has got several areas that I'm sure you will find interesting including a for sale and a live steam discussion board where you could ask if any has one for sale.
Give em both a try & good luck.

John P and others building FN:
I have begun work on the lead (pony) truck, or at least collecting parts and find the casting for the swing bolster to be a puzzle. Why is this one larg mass of cast metal? It makes for a difficult drilling project to get the swing link pivots straight and true. It seems a better way to do this is with 2 pieces of 1/4" plate cut to the contour, bored together, and sandwitched with a plate in between for the center bearing. The holes are lined up, it is easier to make, and probably a bit more prototypical looking.
Any comments?

Hi Don,
You're going through what many people go through when faced with machining an odd shaped casting (including many machinists). It really isn't all that bad but it does require one to think through the various operations before starting. Measure the casting to determine how much should be removed from each side keeping the top boss reasonably centered. After machining the the thickness to size, I then hold the casting upside down in the milling vise and level off the two points before tightening the vise. A very small amount can then be milled of these two points to allow the casting to rest level and square after being turned upright. To machine the top boss, mount the part on a lathe faceplate holding it with a threaded rod through the center hole. I usually have an aluminum plate at least 1/2" thick mounted on the faceplate to be used as a fixture plate(a sacrifice plate to be machined as needed). After centering the workpiece, machine the outside diameter of the boss to the correct diameter along with the flat face at the bottom of the boss. Before loosening the center stud, clamp the part to the faceplate with the clamps bearing on the flat surface machined with the boss. Remove the center stud and machine the top surface and inner diameter and spring seat. Then lay out the swing motion holes and drill and ream them in the milling machine. It all sounds much worse than it is. If any of the above needs further clarification, please let me know.
Have fun.

Thanks for the encouragement, but I still think the part would be better made from plate. What was the attachment you sent, I couldn't open it?

First off, It's true confessions time. I'm a newbie/wannabe/lurker type on this list; I'm a backyard G-Scaler who hasn't been near a lathe since high-school shop class! But I live reasonably close to the L.A. Live Steamers site, and every time I visit there I have a great time, and come home wondering "gee, you suppose I *could* ...?"

But I'll bet I'm not the *only* wannabe lurker here... so on behalf of us all, may I ask a question of you folks who so obviously know what you're talking about?

What the heck IS a Fitchburg Northern? What's its wheel configuration? What's its design prototype? I've been going through the message history and the files section, and seen pictures of frames & bolsters, but nothing of a complete engine design. The only clue I can find is that somebody makes a C-16 style firebox door that fits. Is it a C-16? Or similar?

It's been a fascinating discussion, and I've been learning stuff just by lurking. But finally, I just gotta ask! So if anybody can post a note about the prototype, or first model, or a picture, even a url to a site with such stuff if you've got the time, this newbie would appreciate it.

Thanks for your patience,

-Gary Woolard-

Mike,

Hello!

The Fitchburg Northern is a 2.5" scale 7.5"/7.25" gauge 2-6-0 offered by Allen Models.

The prototype would be a rather small 3' gauge plantation engine. Of course in 2.5" scale she makes an neat engine of some size, and her design is exceptionally well thought out. I own a copy of her plans just for reference matrial.

A C-16 would dwarf this engine, but one should always look for quality parts to use.

Keep asking questions,

Curtis F.

Hi Don,
Don't forget the upper portion of the swing bolster. The springing arrangement on the front deck locates and bears on it. No attachment.

Hi Gary,
If you have or can get access to Live Steam magazine, the Fitchburg Northern construction by Tom Rhodes was serialized in that publication from Feb., 1988 to April, 1991 inclusive. There are 29 segments covering this engine.
The locomotive construction is quite straightforward but requires some machining experience along with at least a 9" swing lathe and a milling machine. I'm building five at present and find Tom Rhodes series along with the Allen Models blueprints to be easy to follow. If I can help anyone on this engine please let me know.

Fitchburg Northern #35 was designed and built by Thom Rhodes of the Adirondaxck live steamers. It is a generic (no true prototype) Mogul (wheel configuration 2-6-0) based roughly on a 3 ft. guage engine. Long "how to build" series in Live Steam magazine a few years backI'll stop now as your posting suggest too many tangents to take off on Hang out at LALS and pick brains.

Allen Model makes a Fitchburg Northern kit. It is based on the components of the Chloe like the original freelance locomotive. If you get one of Gene Allen's catalogs it has a good photograph of what it is supposed to look like.

Hi Gary Woolard:
Welcome to the land of lurkers, wannabies, etc. Actually, if the truth be known, many of us are wannabies to a degree. Most feel they can't do it but are willing to talk about it (building a steam engine, that is).

I got interested in the Fitchburg Northern project about six months ago, after reading through the series by Tom Rhodes in "Live Steam" magazine. I have about 15 years of "Live Steam" as a resource and ocasionally start reading through some part of them. I have more unfinished locomotives than completed ones, but now that I am partly retired, perhaps I can complete some of them. Current projects are the Fitchburg Northern and an electric traction locomotive.

The FN has been described by several people already, so I will only add that Tom did a freelance design based on Baldwin Loco Works parctices for narrow gauge locomotives, so it looks quite nice (especially if you are a Baldwin fan). It is a smallish locomotive, with 5" diameter drivers, so is not intended to be a race horse, but to lumber along as most narrow gauge locos did, hauling "stuff" around short line railroads. That makes it a good project for people with moderate machining skills and equipment. It is also small enough that transporting it to the track isn't a big problem. (Although it will be more than a handful ;-) ). I am working on the frame, tender, lead truck, and a few accessories. I'm not in a hurry, but would like to end up with a good piece of machinery, so started the FN discussion group. People like Tom Rhodes and John Piling are kind enough to provide answers for me and for the lurkers and wannabies who are afraid to ask.
So don't be afraid to ask, you may find your G-Scale gets a big brother.

I too started as a lurker. I now have a 7.25" Live Steamer and a battery critter in the works. My plan is to build an engine in BOTH gauge 1 and 7.25". This way the kids get to run a small version of their fathers toys. That is, when they aren't running daddy's toys.

I don't a big price difference in the two gauges if you are willing to do the work. The big exception would be a large live steamer. The price of good gauge 1 stuff will buy you enough materials to build a decent battery critter. Okay, maybe add a couple hundred bucks, but it's still not that big a jump.

I have also been the beneficiary of a couple really good deals on unfinished engines. My best advice would be to prowl all the places where stuff is sold, especially ebay. But, be careful, I have seen plenty of stuff sell for MORE than retail on ebay!

The other bit of advice is to find and join your local club. Many clubs have an associate level for a minimal fee. This will allow you to hang around and ask questions. If you're lucky they may even have a gauge 1 group. If not, start one, I did! There's nothing like doing work for the club to put you in good graces with the folks who "know".
