Charlie,
I have another dome cylinder available, so why not? It's too big for any of my projects.

David Price sent me a photo of his engine with the steam dome installed, and I wanted to post it for completion of this thread. He has done a really fine job with loco, which represents one of the RGS20 sister engines that went to a logging railroad in Lousiana. I'm eager to have a hand running it at the fall meet at Eagle Point!

I do not remember the diameter we worked the wood plug to. Mune us 7.1 in diameter

Just wondering I would not have thought to use bondo on a steam dome what is the temperature rating on that stuff? Has it held up to a fired and operational boiler?

If you use poly filler (Bondo, which is a name brand) for minor imperfections should be fine. One thing you want to make sure first is that you sand the metal first before apply the poly filler. At work I play with some high temp poly filler, it is I think rated for 600*F I will have to find the spec on it again.

I used JB Weld. Rated for higher temps than Bondo and sands down just fine.

Although I haven't felt the temperature of the dome casing, I don't think it gets very hot, since there is an air gap between it and the actual dome. Also, the bottom of the casing sits on the boiler jacket, not the boiler. So while the dome casing gets warm, it isn't that hot.
