Re: Building the 2.5" Scale Shay

Been a while since the last update, been learning about woodworking and making some test shavings. But have the framing for the engineers side roughed in. Still needs a little fine tuning and then holes for the dowel joints drilled. But can’t assemble it anyway till I have the wood for the inset pan...

Re: Free 2D CAD Software?

Fusion360 does have a bit of a learning curve, but theres lots of videos on YouTube about how to accomplish various tasks. Its my go to for CAD these days, I loved Solidworks, but I cant afford it

Re: 2 1/2 in. Heisler

I would think maybe a 90* zerk fitting and grease the wrist pins. As for the crosshead guides, with that 45* angle making things trickier, maybe just one big cup on the upper part of each guide and let gravity deal with getting the oil onto the lower guide surface. As for Nelson Riedel, I can still ...

Re: Building the 2.5" Scale Shay

More work on the shay now that school is out for the holidays. Got the cab all mocked up in foam board. Had to enlarge it a little bit from the prints because the decking on my shay is wider than the prints call for. I’ve already tested it out some by climbing up on the stand but I’ll take the whole...

Re: Kit Iron Castings

For the small equipment like we have, making things like wheels and cylinders our of grey iron has never been an issue that I've seen. There have been a few cases of chipped flanges, but the ones Ive seen were usually pretty thin to begin with. I have grey iron drivers on my shay and so far they don...

Re: Possibility for a 2.5" scale dynamo

Hallo Soot n' Cinders, Your idea using a simple gear wheel instead of a sophisticated turbine blade wheel to me seems o.k.! Makes just a small difference using the same nozzle. Choose a wheel made of aluminium of the biggest diameter fitting into your housing. That cheap DC-motor of your choice is ...

Please keep us posted — how about a build diary?
I will if I venture into this. Running out of free time at the moment.

Re: Possibility for a 2.5" scale dynamo

I figured I may give it a shot since the generator is only $25. Would have to see if 3000rpm is fast enough to generate enough torque to make 15w of electricity. And just to be clear, I wouldnt use a true turbine blade. Too difficult to make. What I would use is a paddle wheel turbine, or a vane mot...

Possibility for a 2.5" scale dynamo

Alright guys, time to tell me how crazy I am! Looking around online I stumbled across a 15w generator meant for a small wind turbine and wondered if it would also work for a small turbo generator. No load voltage is 12v at 1000rpm, but it can sustain 12v at 15w with higher RPMs, the spec sheet says ...

That extra petticoat makes sense. On full-sized logging locomotives I have worked on, some had "annular venetian blind" petticoats:
Several tapered rings stacked together. An interesting setup for oil burners.

Re: Oil burning boiler mods

If going with a dome throttle, I've been very pleased with the arrangement I came up with. I have a globe valve with the threads on the stem removed so it operates as a push-pull valve. The valve is centered vertically between the top of the dome and where the throttle rod comes through so there is ...

Re: Larry Fisher

My condolences to his family! I always enjoyed seeing his work and was looking forward to many of the beautiful pieces of locomotive jewelry he was developing. He will be missed
