Re: poly cord advice
We made a jig out of a chunk of 2" diameter aluminum. Drilled a .25" hole through it then cut it in half on the band saw straight down the hole. Heat the cord, stick together in the jig and clamp it. The aluminum does a good job of pulling the heat out of the belt and it cures in under 5 minutes.
Since we made two of those we haven't had a failed belt. Prior to that we had one fail every four or five times. With the two pucks we made, we can weld one and while that cures set the next one up.
