Poly Cord

[mathking]

We used a piece of steel angle as a jig, clamping the two ends together. We used a creme brulee torch (a small butane torch) to heat the pieces together. As was pointed out earlier, they then need time to cool completely before they are used. Also, be really careful when you sand or cut off any bubbles or bumps. I recommend practicing on a few short bits. One of our mentors and one student became very adept at the welding, so we had one of them do it whenever we replaced the cord.

Side note: If you use polycord that needs welding, you are going to want to have a bunch of replacement lengths already welded when you go to competition. (In general no open flames allowed in the pit area.)
