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

Okay, I used Advanced Search (duh) and found the post where Wayne pointed out these heaters and @eec1910 bought off eBay - they are still for sale.  The thread is: Elektro runs - homemade Teflon rings and new band boiler.

Part / Sale item is called: 110V 380W Injected Mould Heating Element Band Heater 35x35mm 2pcs

Information from the eBay Sale:
Rust resistant steel sheath, stainless steel clamp type lock-up, notched sleeve allows installation, flush with nozzle hex.  It is mainly used in the heating devices of plastic injection machine stuffing container.
Power : 380W;Voltage : 110V
Band size : 35 x 35mm/1.4' x 1.4 inch (inner Dia.H);braid lead length (each) : 31cm/12.2''
Package Content : 2 x stainless steel band heater

Now that I have a photo, I can see that I only need the outer steel band (I have that) this heater from our friend Pres. Xi, then something to stick inside for heat displacement - then a cover of course.  I'll be get getting another B30 in soon, so I'll be able to steal its A/C cord power pins.  Cap the sight glass holes for now, with proper pipe thread bots and bob's your uncle.

@komet163b I am kind of cursing you ATM - I been fussing about this since your post that I should hold on to this B31 LMAO!  Actually, you are the best :-)

Edit: Hmm, seems there is some Mica involved too.  I think I see it now but that doesn't look like the mica I took out of my B-31.... is that "fresh / new" mica?  Source?
