Pulley/Fan Belt Welding Jig

Fan Belt Welding Jig Holder. This is a jig that holds the belt material so both ends are centered on each other,
then the belt ends are moved apart and heated with a soldering gun special tip,and the jig then closes the two half's together and thus forms the weld.

Captain,
How fast do you have to work between withdrawing the soldering gun tip and closing the gap to form the weld? Also, is there any surface trimming needed for the welded joint after it hardens? This looks like an interesting jig for making my welded urethane belts for my small Unimat lathe and milling head setup.
Thanks for showing this, Paul

Hi Paul, It is important to move the hot ends back together as quick as possible, With this machine the ends are mated perfect.
Hello ED, urethane belts, they come any length you need and size on e-bay just type in urethane belts.

Thanks to all for your interest....:O)

Great idea Captain , as I also never thought of using urethane as a pulley belt.
When heating ends , would it work easier if you added a thin flat blade to the tip of the soldering iron to act as a heating surface and then press the two cut ends together or use the thin blade as a cutting blade which also provided enough heat to allow fusion of the two cut surfaces..?
