Subject: RMI Sweet Creek
Hi Folks,
We just started assembly of an RMI Sweet Creek 2-6-0 destined for the Toronto Railway Heritage Centre. So far it is going really well, it only took six hours to get the frames, wheels, axles, cranks and brakes assembled. Paint will come later.
Has anyone who has done this before got construction advice, stories, anecdotes etc they are willing to share? (Nothing negative about RMI please!)
Regards,
Michael Guy

Subject: A dream come true - Building a 2"-scale live steam Shay
Hello,
as the new logging branches on the Bear Creek Lbr.&RR have steaper grades and the log trains are heavier, the little Forney isn't able to haul all the loads alone. So a second steamer is needed to bring down the log cars from the hills, while the Forney will haul them on the leveled tracks along the creek. So, the railroads president decides to order a Shay for the logging operations.
While the BCL&RR is a small 30" gauge railroad, only a small Shay would fit with all the other railroad stuff. So I'll build a freelanced 10 ton class A Shay with T-boiler. I use several drawings from NG&SL-Gazette and Finescale-Railroader for reference, as also the two Kozo books.
In December 2008, I came back to my idea from late 2007, to build a live steam Shay. I ordered 4 spoked wheelsets, some gears and a number of steelbars for the tracks. Meanwhile, the wheelsets and crown gears are assembled and I machined the journal boxes from steel bar. I'll finish the pedestals next and will then start with the bolster.
I update the progress of my Shay project on my website in weekly log reports. I'll also host pictures from every step. Have a look at www.shay.de.ki (sometimes, this shortcut doesn't work, so go to www.gerds-modellbahn.de, click on to the Bear Creek banner and look inside the rolling stock section.)
This Shay will be my birthday present for 2010 when I'll become 30 years of age, but I think the first roll out will be this year ;-)
Cheers, Gerd

Hi Tom,
Yes, a friend and co-builder has put a few up on Flickr:
We got the side rods on this evening and lo! It turns over! Amazing.
Rather oddly given the high accuracy of the work by RMI on the axles, wheels, cranks and siderods, they chose not to drill the holes to mount the motion plate and crosshead guide bars. As a consequence we spend a long time this evening positioning the plate and drilling and tapping for the bolts - slowed us right down that did! <grin>

Michael.

A friend and myself are looking at colaborating on a Garratt. It'll be freelance so we're trying to gather info. on suitable chassis for the power bogies (shouldn't be too difficult) and boilers.
My biggest concern is to be able to make enough steam for all 4 cylinders so the boiler will likely have to push the limits of any code.
I am in New Zealand and we use the Aussie boiler code.
Thinking out loud... What is the largest size boiler that is "legal" in each country without going to "commercial grade"?
Still thinking out loud... I think the Aussie code dictates no more than 40 litres -I may be wrong, I don't have it to hand. If a "foreign" code were to allow a larger boiler, and it is certified, what would happen if such a boiler appeared in New Zealand?
I have visions of a 2' 6" gauge Sierra Leone Government Railway 2-6-2 + 2-6-2:

John,
Live steam models ( www.livesteammodels.co.uk) have 2" diameter vacuum gauges with back flanges.
As far as I'm aware, model engineers suppliers over here (UK) only have up to 2" diameter gauges, and most commercial outlets only start at 4". And the problem nowadays is that anything modern is calibrated in bar, not PSI, which just doesn't go with a steam engine. There is hope, however: just keep an eye out on eBay - I have bought several gauges that way, you can get some real bargains. For instance, Siusaidh's gauge is 6" diameter, 0-250psi in brass and cost me £15 on eBay.

Subject: Re: Big (steel) boilers and boiler codes
John,
I seem to recollect that an Aussie friend of mine said that the Aussie code allowed boilers under 50 litres. Given the size of boiler that he was going to build (49 litres), I think that, with a good sized grate (about 90 square inches) then it ought to manage with 4x2.5" diameter by about 4" stroke cylinders (say two tinkerbell chassis or thereabouts).
My guess is that, even if a larger boiler built elsewhere (and in the UK we allow bigger than this) were to appear, then it would depend what the local legislation allowed. Certainly, over here, it must comply with our rules and our rules alone - even if it complies with someone elses, if it's disallowed here, then it's disallowed. One such sticking point is stainless steel boilers - which most European countries are happy with but the authorities over here are not.

A friend and myself are looking at colaborating on a Garratt. It'll be freelance so we're trying to gather info. on suitable chassis for the power bogies (shouldn't be too difficult) and boilers.
Interessting project. I'm about halfway through building a 2-6-2=2-6-2 Garratt in 7 1/2" gauge. Mine is very much freelance but does use the castings and plans from Allen Models. I have started with the Allen Consolidation plans, but have eliminated one set of drivers and added a trailing bogie. The cylinders are 2" bore and 3 1/2" stroke and the engine uses Baker Valve gear. (told you it was freelance!!)
My biggest concern is to be able to make enough steam for all 4 cylinders so the boiler will likely have to push the limits of any code.
I have built a rather plain Briggs boiler using a 10 5/8" OD steel Schedule 40 tube. The tube is 34" long but the crown sheet is around 15 3/4 long, if I remember correctly.
Smokebox is 9" long I think. I made these parts a couple years ago so I'd have to actually measure them to find out any real details.
I have visions of a 2' 6" gauge Sierra Leone Government Railway 2-6-2 + 2-6-2: http://www.worldrailfans.info/7.25inch/workshop.shtml
That would be a rather large engine if built to scale. And quite a nice project for two guys to build. My problem is that storage and loading gauge limits my engine's width to around 20". Mine is turning out to be 18" actually. I'm using a lot of features of the NGG16 bodywork. I also have the drawings from South Africa, which are indispensable.This loco will end up being around 11'6" long but is not a ride-in-cab type.
I may get it done someday, but I'm currently sidetracked on two other locos and a bunch of projects, as is common among Model Engineers.

I've checked a couple places and looked in my junk box, but it looks like 3" is a rather odd size. No problem with 2" though.
I wonder how gauges are sized too. Some are sized by the dial diameter and the case is always much larger. That said, perhaps you would want to look at 2 1/2" dial size which would result is about a 3" case diameter.
The obvious solution is to get suitable gauges then pull out the works and put them into your own brass case. It isn't difficult to make a press die for 1 mm thick brass.

Hi,
I'm looking in my AMBSC Boiler Code - Part 2 - Steel Boilers, Isuue 4 - 1995.
I do not know if there are any newer issues released. Anyway, paragraph 1.1.2 states that:
This code applies to ... boilers having a working pressure not aeceeding 700 kPa. The maximum outside diameter of barrels and drums shall not exceed 356mm (14"), and the boiler length shall not exceed 2000mm (78 3/4").
In a note it is stated that a boiler
... inspected and certificatedby AMBSC appointed inspectors shall have a water capacity not exceeding 50 litres for fire tube boilers and not exceeding 25 litres for water tube boilers.
It is also noted that boilers larger than 50 (25) litres may be built
... under the auspices of the relevant State regulatory authority.
I guess you have to find out what applies in NZ.
Good luck with your project.

There is a magazine which many will know about it's called The Australian model engineering they have a retail outlet that supplies the current steel and copper codes.
The largest steel boiler that i am aware of built to the code is a steel briggs boiler built for a series of construction articles on a Queensland bundegberg 2ft gauge fowler running on 7.1/4 guage track.
With a gross water capacity of 49.9 ltrs.
Out side of this scope you will end up with a larger boiler that will have to be inspected and registered outside your club and the plans/design will have to be approved else where.
Depending on the size you may also require a boiler/reciprocating engine ticket!!!

Hi Tom,
We asked RMI to make the back to back 6-3/4" to match the proper standard for 7-1/4", the IBLS so-called standard of 6-7/8" is incorrect.
We are going to try and make the track flange-size insensitive. I built a portable track switch a few years ago with a moving frog wing-rail - it doesn't care what the flange depth is or the back to back dimension. I am hoping we can use a similar design for the new track, if so, we may yet be able to see Jim's engine run here.

Subject: Valve gear re-design
Thinking out loud ... (as I am prone to do), I am looking at using the chassis design from a L'il Lima (2-6-0) for a Garratt. I'm looking at this design as (1) being narrow-gauge it is quite chunky, and (2) it has Walschaerts valve gear - which many other potential locos don't (Romulus, Tinkerbell, etc).
Not being an expert in the design of valve gear I really want to be able to use an off-the-shelf design so that it stands a chance of working, however, this design is a little unusual (for a Garratt) in that it drives on to the 2nd of 3 axles.
Is there any reason why you couldn't extend the eccentric rod and connecting rod and move the drive to the 3rd axle?
I appreciate that the angle from the bottom of the expansion link to the eccentric will be slightly different, but is it going to adversely effect the valve events?
I am assuming (usually a fatal thing to do) that the critical relationships are between the crank throw, expansion link, combination lever, steam ports and valves - none of which I plan on changing.
Is there anything else I should be aware of?
Any help would be appreciated.
Thanks,

I'll see if I can dig it up before I go to work. It wasn't too far back, a couple-three issues. The "article" was more of a letter with photos from a fellow in Norway, if I recall. He might have showed guard rails, but you don't need them...there's nothing to "guard", and we don't have guard rails on the mainline. It would seem to me that you could spring-load the throw rod so that you could even trail through it without tearing it up.
The only problems we've had with the movable point frogs is when somebody takes the switch "on hand", and forgets to line the frog along with the points, and splits the frog :>) The Section tells me that they are a lot less maintenance than the solid frogs, but then you fellows wouldn't be welding up the solid frog noses every couple weeks like we do :>) They ride lots better than solid frogs, account you are essentially running on solid rail instead of over a gap in the rail.
All-in-all, it's a lot simpler than some of the ways folks have used to run both 7-1/4" and 7-1/2" (or 4-3/4" and 5") on the same track.

Ok fresh year, will try again, does anyone know of the fellow that was selling cast iron Andrews trucks they were available either as a kit or RTR? He had a web site but he shut it down and was going to keep making parts.
Thanks Boyd up in the sunny but cold northwest without snow.

The only Andrews trucks I'm aware of were aluminum and are no longer produced. I own a single truck of that style.

I might be able to copy that truck in aluminum, if anyone is interested. Send me a picture, or a drawing, ... or the truck.
Merle.

Sounds like the iron ones may be the fellow will email him ASAP as need to find another set. OOPs just saw the area code isn't the one. I have seen those trucks and they are very nice looking a fellow had them on a chip car at Train Mountain last year and they worked great and would recommend them to anyone wanting trucks as the price is right and if you come to TM they could be delivered there with a little advanced notice am quite sure. I come by where they live so could bring them down with me to a meet.
Well it was worth a try anyway and the way these are made aluminum would not work. Will probably just deal with it later as have the SW7s to get painted. And I thought that painting a full scale Cessna airplane was work these engines are kicking my you know what. Since they are going to be black the sanding has to be perfect no scratches or pits which means another coat of primer and another wet sand with 400.
Thanks all for the info have a wonderful day and lets Rail Road again.

Hello all:
Question from a lurker: I have been looking at these pictures from here as well as from other sources for quite some time and I keep coming up with the same question -- what and how is the other end being actuated? I don't see another switch stand nor can I see any rods going down the way?

I'm not sure what you mean by "other end". At the frog, the point is the only part that moves, when it does, it bends the rail on the solid side. The other side is a slip joint for flexibility. On the BN, we have two electric switch motors, one for the points and one for the frog. Some of our "high speed" points are so long; we have a pull rod system on them, to get the middle part of the point moved over. I'll put a photo in the folder with the frog pix.
The 7-1/2" version could transfer motion from one switch stand by pull rods, or a bar and crank system. The fellow in Holland uses a solid wedge shaped frog point that is pivoted at the heel end. They use bar stock rails, so they just welded some plates with bearing holes to the outside of the rail. Then, they ran a round bar, or piece of pipe (I can't tell from the photo), through them with a lever on each end that hooked to the throw bars. The points always move the same direction as the nose of the frog, so you don't have to reverse direction or anything.
Hope this helped.

The actual rod that moves the points (and frog) is just a, part rectangular, part round bar that comes out of the side of the electric switch motor. I'll have to see if I have any pictures of them. If I do, I'll post them in
that album.

I found a couple photos of the throw rod, and the switch motor, on a frog, and posted them.
Point linkage
The linkage to pull the middle part of high speed points over.
Point Detail
The throw rod on the movable point.
Heel of Frog
A view from the heel of the frog. The aluminum-colored box on the ground next to the track is the switch motor. The tower next to it is the propane switch heater.
