@komet163b I am not sure what you are tying to tell me about "Fore-warned, is fore-armed.".

So I have gone out on a limb on trying to source some Nichrome off Amazon.  The wire on the #90 heater is really small/narrow - I really need to get a good ruler.  But it can't be more than a few millimeters while.  Though I might have screwed myself as I cut the tails off the iron plate so the heater cartridges I bought would fit better where the wire comes out.

Amazon: xcell 10M 33Ft 0.2x2mm Nichrome Flat Heater Wire for Heating Elements.  Someone asked the vendor the resistance, they reported 2.25 Ohms/meter = 0.69 Ohms/ft
mcmaster.com #85825K42:  Flexible Electrical-Insulating Mica, 23" x 39", 0.008" Thick

I already had the Mica, so I have started the laying out the bits.  I am just not so sure if I need to add more sheets.  Maybe one or two more?
