Re: [TCML] Secondary Wire splice technique, gear reducer 4 sale
Try Environtex epoxy. It works good. You have to use a heat gun to work
out the bubbles as you apply it with your jig turning. I use in in 3/4"
thick layer. It is a 2 person process.
Dolph's AC-43 also works well.
At this high power level it would be best to have a continuous length
