Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I just ordered one of these myself (the 2nd one) for a B31.  I figured what the heck!  Is that a socket in the middle?  That is ingenious (in the B31 thread the member made a brass bit).  Also in the B31 thread he mention "mica" - I assume so it can be around the outer edge?  I can't tell, do you have mica too around the heater (around the outer circumference of the heater/inner tank)?  I assume that it is important to have that barrier between heater/tank edges.

I am also looking at Insulated High-Temperature Ring Terminals from McMaster-Carr (300 F) to put on the end of the wires (darn out of stock).  Might anyone know the screw size of the Empire's inner studs (I think they are 10-24)?

Lastly, thank you Wayne for your post and URLs to the heaters - you are a star for sure!
