I’m okay with the air cooling method, its the delivery system that needs a doooo over....the air cooling system could use a bigger blower and at least a 3/4” radiator type hose and a filter.

Here’s the furnace after 3 winters use (and a little clean up). No problems other than Bussman fuses blowing.

Just finished adding a new pot, air ram to open the door and a ceiling blower to help keep the connections cool.

Thanks Lawrence, I think that really helps. James Burt has bought the 22.5 KW electric package from me and I'm trying to convey how that front plate works. I've advised him to get the plate and then design around it since he wants to bring the 24 inch pot out the front ( What a concept) . Mine, on the 28 inch electric package tilts back a bit on the back of that casting but presents in essentially the same way as yours. That's a great sequence, thank you.

I really will miss my moly.

I'm about to start a medium size gas unit using an 80 lb pot and two 11 inch pots for the time Scott and I will melt enamels if there is an interest.I could use it as a permanent smaller furnace as opposed to the larger one. It will use a recuperation system Charlie Correll is building. I'll do it from the first weld if there is an interest.

Otherwise I'll just build it.

Lawrence-

Those pictures are terrific! Thanks for posting them.

As Pete mentioned, I'm going to be taking on a build of a moly furnace, and have been having trouble visualizing some of the casting that Pete has been recommending. Seeing your furnace helps considerably!
