Discovered that the 3 wheel bandsaw I borrowed had a blade, but no drive belt. Found that none of the suppliers nearby have a belt this small, so wondered about making a belt. Tried heat welding some 6mm vinyl (hospital) oxygen tube....wouldn't weld. Tried some 3mm whipper snipper line, worked really well. Stood a piece of old hacksaw blade in the vyce, heated it red hot with a little butane gun, put the burner aside, rubbed the plastic on each side of the still hot blade, then slid the melted ends together, held them for a few minutes to set. Cleaned up the ridge on the bench grinder. Lasted about 15 minutes on the saw before it broke, repeated the weld, lasted about 30 seconds, repeated the weld and it's now held for about 5 mins to the end of the job. Also tried some 5mm camping twine, braided polyester stuff, joined with heatshrink tube, worked for a few seconds, then the heatshrink that was between the ends of the cord stretched, lost tension. slipped and wouldn't drive.
