Greeting to all list members!

I've just joined this "group" / "list" and I hope I will gain further knowledge on large scale Live Steam modelling and railroading!

I currently busy building a South African Railways Class 6A (4-6-0) tender loco, to run on 7.25" gauge. (approx. 1/6th scale).

Should anybody would like to know more about SAR locomotive please place you message on this "group" / "list", and I'll try my best to help the guys out.

Steamy Greeting, from a hot and sunny South Africa.

"If my life weren't so close to a tragedy I'd be a comedy of errors."

That's enough griping about the past few months of my life.

Just this past weekend I finally got back to doing some serious CAD work and wanted to toot my own horn a little. Yes, I take pride in my work even if it's just electrons & paper.

A friend is a serious "gear head" and wants to build a West Side Lumber Co. #10, so a couple of years ago he dumpped a pile of Lima blueprints in my lap. While regathering my papers on Baldwin 4-4-0s I found the Lima prints and let them divert me for a few hours.

I've put 5 CAD rendered images in the Photo section of the group of some early returns on frame design. (http://photos.groups.yahoo.com/group/7-plus-NGM/lst)

Some statistics on the engine to-be:

70ton 3 Truck Shay of 1928 (Possibly worlds largest 3' gauge shay)
Buit for Pickering Lumber Co. (Later "West Side Lumber Co.")
http://www.shaylocomotives.com/data/lima3354/sn-3315.htm

Scale: 2.5"
Gauge: 7.5"

Bore: 2.5"
Stroke: 3.125"

Rigid Wheel Base: 10.83" (each of the 3 trucks)
Driving Wheel Base: 100.5"

Drive Wheel Dia: 7.1"
Gear Ratio: 1:2.25
Speed at normal (400rpm) operation: 3.75mph
(2 hours 56 Minutes for the 11 mile Trainmountain Mainline)

Indicated Horsepower @ 140psi.: 3.1hp
Calculated Tractive effort @ 140psi.: 558lbs


Engine Frame: 3" I-Beam 82.45" long.
Engine Width: 21.25"

Boiler: 12" Dia. pipe with 1st course reduced to match 10" Dia. pipe.

Only a few detail parts (coupler pockets, polling pockets, truss rod castings) from Richard Ulin's shays will fit this engine, the rest my friend plans to carve from solid or weld up. Unfortunatly he's not interreted in any type of production run for this engine, which could also make a WSL #8, #9 or Oahu Railway & Land Co. #44. :-(

Well, thank you all for reading this far, I do appreciate it. :-)

Happy Holidays,
Curtis F.

Hallo

I Ronald up to now have build a 0-4-4 O&K 0-4-4 O&K like they use in JAVA and a 0-6-6 Decauville from 1 WW all on 7 1/4 with injectors, steam braking etc last 12 yaers

NOW me and my friend we have 35 acres ground near the ocean in France

AND WE WANT TO START ON 15"

so we need a plan for a good performer, passenger hauling steam engine, sorry but not western style but a small big one can be Plantation up to K 27,28,36,38 well I know sometime a small 040 or 030 can be a better performer as a big beauty and be even bigger than ......
It should be a big one as on the ground will be a small steam museum, and the train has to run all the days.....

Curtis;

May want to consider changing the ratio to 1.50/1 then won't hold up traffic on the TrainMountain run.

Last month at the Riverside Live Steamer Fall Meet, there was a two truck shay running, but the ratio was almost 1/1, so the locomotive was very fast.

Just may thoughts.

Ahoy!

FYI Alexander Gramm Bell originally wanted people to answer his phone with "Ahoy." It was Thomas Edision that convinced him that "Hello" might be a better choice. Edison got "Hello" from time that he spent in the Appalchian (is that spelled correctly?) Mountains where the people would communicate by hollering across the valleys, and the way to get someones attention was by yelling "Ha-lo". Science later showed that the "h" and "l" sounds are amongst the top sounds that will travel long distances.

Anyway, on to 15" gauge!

You need to ask this in the 5inchsteamtrains yahoo group, I know you're a member there and there's more grand scale people over there.

Have you tried the Hillcrest Shops? http://5inchsteam.8k.com/

AND Historic Railway Consultants? http://home.earthlink.net/~wsflco/hrc.htm

H.R.C. and Hillrest advertise a 5" scale 15" gauge 0-4-0, but they don't advertise the custom work that they can do. These guys, thanks to an extensive network of friends, can build just about anything you want. And if you want english stylings and they say they can't do it, have them contact me (they have my phone number) and I'll show them what needs to be done. ;-)

Try giving them a hollar,

Subject: Latest on my Petrol Electric Loco



Hi Guys and Gals,

It's been a while since I brought up a bunch of questions about running direct petrol/electric without going through a battery, well thanks to a whole lot of good advice and encouragement, tonight the loco moved under it's own power for the first time, and I even tried sitting on it and it moved me too, a momentous occassion at Squirrel Valley Railway. My first truly scratchbuilt loco, and it runs.

There's still a heap of work to do, but I can definitly advise that 100% yes, you can control an alternator by direct control of the field windings, and the speed of the loco can successfully be controlled from here. It's a pity that reversing can't be affected so easily as the output of the alternator is rectified AC, and it doesn't matter which way round the field windings are powered, the final DC output is the same. But, I was sent a great big relay from a WW2 plane that operates on 24V and has HUGE contacts which will be my reversing relay.

As for the body work, the painting is nearly finished, in fact it's just the stripes that remain to do, I have the handrails then to install, and from there it's just basically detail's, lots of details. And most importantly, the cab space has remained clear of obstructions, so I will be able to detail the cab afterall.

Will post photo's in the archive section when I get some!

Subject: FW: Armed Forces Pay



On 12 Oct, Ms Cindy Williams (from Laverne and Shirley TV show) wrote a piece for the Washington Times denouncing the pay raise(s) coming to service members this year - citing that the stated 13% wage gap was bogus.

A young airman from Hill AFB responds to her article below. He ought to get a bonus for this!

Ms. Williams: I just had the pleasure of reading your column of 12 Oct, "Our GIs earn enough" and I am a bit confused. Frankly, I'm wondering where this vaunted overpayment is going, because as far as I can tell, it disappears every month between DFAS (The Defense Finance and Accounting Service) and my bank account. Checking my latest leave and earnings statement LES), see that I make $1,117.80, before taxes. After taxes, I take home $874.20. When I run that through Windows' Calculator, I come up with an annual salary of $13,413.60 before taxes, and $10,490.40 after.

I work in the Air Force Network Control Center (AFNCC), where I am part of the team responsible for the administration of a 25,000-host computer network. I am involved with infrastructure segments, specifically with Cisco Systems equipment. A quick check under jobs for Network Technicians in the Washington, DC area reveals a position in my career field, requiring three years experience with my job. Amazingly, this job does NOT pay $13,413.60 a year, nor does it pay less than this. No, this job is being offered at $70,000 to $80,000 per annum. I'm sure you can draw the obvious conclusions.

Also, you tout increases to Basic Allowance for Housing and Basic Allowance for Subsistence (housing and food allowances, respectively) as being a further boon to an already overcompensated force. Again, I'm curious as to where this money has gone, as BAH and BAS were both slashed 15% in the Hill AFB area effective in January 00.

Given the tenor of your column, I would assume that you have NEVER had the pleasure of serving your country in her armed forces. Before you take it upon yourself to once more castigate congressional and DOD leadership for attempting to get the families in the military's lowest pay brackets off AFDC, WIC, and food stamps, I suggest that you join a group of deploying soldiers headed for Saudi. I leave the choice of service branch up to you.

Whatever choice you make, though, opt for the SIX month rotation: it will guarantee you the longest possible time away from your family and friends, thus giving you full "deployment experience."

As your group prepares to board the plane, make sure to note the spouses and children who are saying good-bye to their loved ones. Also take care to note that several families are still unsure of how they'll be able to make ends meet while the primary breadwinner is gone-obviously they've been squandering the vast piles of cash the DOD has been giving them.

Try to deploy over a major holiday; Christmas and Thanksgiving are perennial favorites. And when you're actually over there, sitting in a DFP (Defensive Fire Position, the modern-day foxhole), shivering against the cold desert night, and the flight sergeant tells you that there aren't enough people on shift to relieve you for chow, remember this: trade whatever MRE you manage to get for the tuna noodle casserole or cheese tortellini, and add Tabasco to everything.

Talk to your loved ones as often as you are permitted; it won't nearly be long enough or often enough, but take what you can get and be thankful for it.

You may have picked up on the fact that I disagree with most of the points you present in your op-ed piece. But, tomorrow from Sarajevo, I will defend to the death your right to say it.

You see, I am an American fighting man, a guarantor of your First Amendment rights and every other right you cherish. On a daily basis, my brother and sister soldiers worldwide ensure that you and people like you can thumb your collective nose at us, all on a salary that is nothing short of pitiful and under conditions that would make most people cringe. We hemorrhage our best and brightest into the private sector because we can't offer the stability and pay of civilian companies. And you, Ms. Williams, have the gall to say that we make more than we deserve?

Rubbish! A1C Michael Bragg Hill AFB AFNCC

IF YOU AGREE, PLEASE PASS THIS ALONG TO AS MANY PEOPLE AS POSSIBLE AND SHOW OUR SUPPORT OF THE AMERICAN FIGHTING MEN WOMEN. THANK YOU.

THIS LETTER SHOULD BE APPLAUDED BY ANYONE WHO'S EVER SERVED OR HAD A FAMILY MEMBER SERVE IN THE ARMED FORCES! THIS YOUNG MAN DESERVES A MEDAL!

Subject: New Loco at Squirrel Valley Railway



The good news is that we completed our first track trials of the new loco last weekend and basically it went very well. The loco is a true Petrol/Electric loco, 7 gauge built to 2" scale to represent a 3'6" prototype loco. There are a few pictures of it's construction in the 7+ archives, but I have yet to post a finished picture of it. All up weight came out at 210kg.

I found the loco to be very powerfull even tho it's only running 24V 20 amp motors, but there are FOUR of them. The alternator I located is ex-army and is rated to give 28V and 140 amps, and driving this is a new Briggs and Stratton 3.5HP 4 stroke motor. Although technically this is perhaps a little underpowered, in reality it does everything required of it (so far) at only about half power. Remember here in New Zealand we rarly haul more than two passenger cars (as well as my engineers trolley and a caboose) so the drawbar loading isn't that great.

I did experience a couple of problems, firstly, after my completing a few laps being very carefull I tried winding it up some. Well, it went VERY fast and cornered like it was on rails! Actually it IS on rails I guess but you know what I mean! Anyway, after I realised I was going a bit quick i shut the controller down and there was a bit of a *POP* and that was it! Upon closer examination I discovered that I had let the smoke out of the FET's and a big diode in the controller, in fact you could see the holes on the FET's where the smoke had escaped. Seems the back EMF pulse from the alternators field windings was bigger than I had anticipated and it took out the protecting diode, and then of course anything else in the controller it could find.

Well, that was a little dissappointing but it didn't stop me cause I simply wired first 12V then 24V direct across the field windings. This really made the loco fly, but of couse with the subsequent "jack rabbit" starts something had to give, and it was the fanbelt between the petrol motor and the alternator. Oh well, it was fun while it lasted, and I now have a belt tensioner so that's another problem overcome.

So, all in all a most successful first run and it definitly encourages me to persue this further.

The problem is very common, you should have a LARGE henry coil to absob the kick back power, this happens in welders also.Contact a welding supply house. You need this inline of your current system, if not your altenator will burnn also. Be aware that the henry or choke coil gets really hot. Put a blower and houseing by the engineer for heat in the winter.

A large "Henry" coil? You mean an inductor? Isn't the problem caused by the field windings already being an inductor, won't this just make it worse, or am I severly ignorant? I hoped that a big reverse biased diode (35amps, 400V) across the windings would shunt this surge down.

Subject: Re: New Loco at Squirrel Valley Railway



Same thing different school. If (I remember my design ) your kick back amprege is close to 4 times the rated power. So 20amps can peak to 80 amps. This is why "The Coil" Heats and absorbs the 1 second of high amprege. Each time you produce more power than you use you get kick back. Thats why regenerative breaking is nice on 1-1 scale units. The excessive power is stored in traction batteries and then to resistence units.
I once worked on an electric car we used a 5.5 hp briggs engine to a generator then to a battery bank then a "chopper" and the to the electric motors. We used NO Electronics to speak of, Even handmade on own voltage chopper. The car could crawl at a pace slower than you could walk and could go 70MPH. Range was around 30 miles if you didnt burn the wheels off. I belive I still have all the original drawings, schematics and notes. Gas was to cheap then to make it pay off. Sorry for rambling hope this helps

Hello all,

first, let me wish you all a Merry Christmas and a Happy New Year and a peaceful holiday season.

Now, that the end of the year is approaching really fast, I wish to thank you all for making the 7-plus-ngm mailing-list such a great success for me. We are nearing the 300 line of subscribers, and the second year isn't over.

As I started this list in 2000, I never expected to get so much subscribers for such a specialized group. Narrow Gauge on 7.25" gauge and wider, that are so hugh models.
But all of you seem to love this scale's, and so I'm happy.

If I sometimes fail to stop some thread - like the discussion "Armed Forces Pay" - I wish to apologize. But my main-goal is to let the list run really free and only to supervise it. I think, we are rouled enough by others, so we should have some free in our hobby.
On the other hand, living on the other side of the pond in Germany, I get my daily-digest one day later, so often I'm not able to interrupt something earlier.
But the good thing is, that most time the group clears it by itself.

So, let me close with the best wishes for the next week and the hope to see some of you sometimes again. Hope to come over in june 2003 for the Train Mountain Triennial.

Sincerely yours
