Not sure if this belongs in the reloading section or the bear pit.

I 'built' an induction annealer based on the video from North East Texas Tactical on YouTube.



The annealer is absolutely fantastic and works better than I ever thought it would.

That being said I bought some materials to custom make my own coils. I got the heat sleeve (good to 600 degrees C) and some 10 gauge solid copper wire. Since the coils themselves get fairly toasty I definitely want the heat sleeve on there, but what I don't know is what they use to secure it to the wire to keep it from fraying or whatever.

I would use regular old heat shrink tube but I think it will melt. I think they do offer some higher temp rated stuff but I have no idea what I am looking at or where to find/buy it.

If anyone knows please let me know. See the photos below for a reference.

Use a temp laser to see how hot that part actually gets? May not be that hot. You could use hitemp epoxy.
 
 
I ended up calling one of the online electrical supply companies online and I think I found something that will work.

I got some 3/8" PTFE shrink tube that shrinks 4:1. It says you have to shrink it with a blow torch but once installed it is good up to 500 degrees F.

Hopefully it works out.

In your third picture, thats called "Pants".
Honestly they call it pants,some of the supply houses like DigiKey would probably have them.
I bought some from Crutchfield years ago but doubt they'd take a lot of heat.
 
I found this video too. Then I found another thread here that builds what looks like a nicer system for ½ the price. Although I have not read the thread yet. I had it bookmarked for later but seemed to have lost it/closed it. If I find it, I'll link it here.
