PU belt alignment tool

a simple alignment tool to exactly join the ends of a polyurethane belt together for welding. PU belts can be custom made by cutting to the correct size and then welding the ends together. See https://youtu.be/nJuQdiyFSB8 on how it can be done. The guy (not me but he describes the matter very well) uses a wooden block, but i think my method is easier:

1. Unscrew the wingnuts 2.Insert the ends of the belt to be joined 3. Melt both ends with a hot knife 4. Remove knife and press the two ends of the belt together until cooled out. The result should be a perfectly aligned endless PU belt.
