Pulley/Fan Belt Welding Jig

This is a great idea, I have been using a V block but that tends to draw the heat to fast, this is a much better solution.

I had to weld a small Unimat-sized belt so I took a short length of angle iron and, in the middle, milled away a section so the belt ends, lying in the V of the angle iron were exposed in the milled slot. Pull them slightly apart and close them on a palette knife that's been heated. While pushing them together on the knife, slip the knife out and the two heated ends of belt are immediately pushed together. (An assistant is useful for this maneuver.)

With the mid-section of the jig milled away the heat isn't sucked from the belts by the angle iron, yet the belt is closely supported so the alignment of the belt ends is good.

A larger version might work for larger belts but I've never had occasion to try it.
