Tristan,

Your Shay is looking good. I've been working on painting my loco as well. It can be a time consuming process but well worth the effort. I'd be interested in how the insulation has affected/improved steaming. While I have the cladding off my boiler I will need to replace the insulation and I've been looking for a decent product. Mine was insulated with cork but its a copper boiler as the loco is in 3/4" scale so no corrosion issues.

Keep up the good work. I'm enjoying the thread.

James, the insulation has made an amazing difference! I use noticeably less coal while running, and the biggest change is how long it takes to cool down now. Used to only take 2-3 hours, now it’s closer to 6-7 hours. I definitely recommend the insulation I used

Curious how thick the insulation is on your boiler? I saw you used 1/8 thick material but assume you likely made a few wraps around with it.

Correct. I did 2 layers so there’s 1/4in of insulation under the jacket. 1/8in May be more appropriate for a 3/4in scale locomotive, but I bet it would make quite a difference on a copper boiler

Any idea how many of these Shays are operating right now? There is of course John's, and your's. Anybody else? Just wondering. Seems like a neat engine.

Greg Glos at midsouth has one operating too. There’s several others that are close as well. Another year or two and there will be a whole gaggle of them running around the southeast

There are at least four of these Shay builds underway in Australia.
