I have recently been in touch with a person that has successfully rewound heater coils for his No.670 Weeden, he has agreed to share his experience:
"I’m happy to share details on how I wired it…
I didn’t know what size, so I bought a nichrome wire assortment on Amazon. I used a caliper to identify the wire that was the closest and that was 26 gauge.
I wore rubber gloves so I wouldn’t get oil from my skin on the wire and used a scratch awl to tightly wrap the wire in boiler length strips (about 4”). I’d pull the scratch awl out and leave about ½’ straight for the return and repeated this 6 times. Once six coils with ½ between each is complete, I assembled back onto the ceramic, re-connected the wires and voila! It’s not perfect, but in all honesty, it’s about just as neat as it the wiring was originally."
Disclaimer:
This is for information only, use at your own risk, the information came from an engineer working in an experimental lab so knows that he is doing.
Thanks for sharing Frank, looking at Amazon it’s not a very expensive experiment to try with my junk Weeden parts...
