Are you lighting a fire in that thing this weekend? :)
Sure, I’ll just throw some greasy rags on a baking sheet and tie it to the boiler with ratchet straps! What could go wrong?

Re: Building the 2.5" Scale Shay

More progress to share on the shay, the turret is complete! Its built up from brass pipe with the body being 3/4"NPT with a 3/8"NPT nipple to connect to the boiler. The ends were plugged with rod and then boiler bushings from PM Research were used to give flat spots and the pipe threads to connect t...

Re: Help with throttle valve

I don’t see any reason that throttle can’t be reused. Just get some lapping compound and take some time to lap the slide and body to each other. Another question is how bad is the leak? Every valve is going to leak some amount. A friend of mine who spent his career working on the D&RGW narrow gauge ...

Re: Building the 2.5" Scale Shay

More work on the shay lately. Money was burning a hole in my pocket so I decided it needed to become parts! The sight glass is now plumbed in with its blowdown valve. The bent copper was brazed into the valve and union after being annealed several times to get the bend right. The blowdown is threade...

Re: So that is why this does not fit......

So the bottom connection is the exhaust and this is prototypical. All of the climaxs I've seen are plumbed that way. The inner connection is the delivery but Im not sure how the passage goes since there doesnt appear to be any signs of it on your drawings. As for prototypical, this could go either w...

Re: NYC h10a

Waterjet is a great process. I had my boiler sheets cut with waterjet and they came out perfectly!

Re: Shay Exhaust Manifold

I just made some brass flanges for mine and brazed them to some copper pipe. Not quite as space efficient as the brass bar but it seems to be working pretty well so far

Re: Building the 2.5" Scale Shay

More work done on the shay, this time plumbing in the lubricator I modified a while back. The check valves are PM Research 1/4" MTP check valves with O ring seals. And inside the steam chest there is a little nozzle that allows the drops of oil to be atomized by the incoming flow of steam. The tempo...

Re: Building the 2.5" Scale Shay

I think you have the wrong thread Fender... More fiddling done today on the shay, valve should be here tomorrow. I have an idea on how I’m going to do my blower, going to start with a simple elbow with a short nipple attached and go from there. Playing with it on compressed air it seems to draft pre...

Re: Building the 2.5" Scale Shay

Im getting bad at remembering to update this... Too much time spent at work I guess lol. Either way, the petticoats now have a frame and are bolted inside the smokebox. Put my PVC test stack on as well and ran some air through the engine and it seems to have plenty of draft, so hopefully she'll have...

Re: Building My 2.5" 20 Ton Shay

Id get the steady rest on there personally. For my crosshead guides I milled the bottoms flat and drilled the lower mounting holes, then I had a faceplate for the lathe with the same bolt pattern drilled and tapped in it. From there I used a live center in the tailstock to hold the casting steady so...
