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 ...

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

Re: Verifying Blast nozzle height

Hmmm, One more question has come up regarding round blower nozzles with multiple holes drilled in the ring. What advantage do they offer over the traditional one nozzle blower? Also, with multiple blower oriface, does this type use more steam than single nozzles? Hence perhaps be less efficient in ...

Re: Crank Pin Alignment

I agree, keyed axles are the way to go! Broach both wheels for that axle at the same time with a dowel in the crankpin holes so the quartering is true. Also, use woodruff keys. Ive seen square keys work loose and start eating into the back side of the siderods.

Re: Verifying Blast nozzle height

Hello All, thanks for your comments on this. In answer to your questions, here are a couple of data points: - my working pressure is 143 PSI. - existing oriface size is .238” for each nozzle, .476” total; (1/7th Cylinder dia rule should be .358” ) - nozzles are offset to the rear and left of stack ...

Re: Building the 2.5" Scale Shay

The second, and biggest improvement was changing the blast nozzle. I started with 9/32, which was found to be too small. The exhaust went from beats to a roar going up grades and back pressure was robbing the engine of power. So I bought a brass pipe plug to play with while the stainless steel one ...

Re: Building the 2.5" Scale Shay

With the stack bolted back in place, it was time to drag it out to the railroad for a test. The solder originally used to hold the bolt rings on, failed while shuffling cars around the yard. So the oxy-acetylene torch was wheeled over and the soft solder replaced with silver braze while A friend use...

Re: Building the 2.5" Scale Shay

So stack work has been under way. Most of the rough forming is done with only one more sheet to flange for the joint to the cones. Glad I went with 22ga material, forming the cones and cylinders was easy but forming the angled flanges was a little trickier. Most of it was done with a piece of 3/8” r...
