Some people say, awe just go buy a new belt. Well I got a floor mounted porter cable machine that uses 4 by 54 belts. Its got a three hp motor on it and weighs a ton. It grinds off metal and wood like a hog. Sharpens lawnmower blades, and does a great job on chisels with 400 silicon carbide. Not only are the belts expensive they are custom made. Research shows that the glue on the belts is only good for a year or so. Same for the taped ones. Ever seen a date code on a belt. Ever seen a date code on a bottle of glue. Not. They dont want you to know how old it is. May be outa date when you bought it. Most older belts are lap joined with glue. Newer ones are butt joined with tape. The tape has heat activated adhesive on it. (just like them iron on blue jean patchs) I am suggesting you iron on some tape before you break a belt that is lap joined. As soon as I find a source of the tape, I will post it. Come on, how much can a roll of glass filament tape cost. I can get an old iron at the thrift shop.

I’m with you. I’ve got about 75 1X42” belt that last about 10 seconds. They are 15 years old. The grit is a klingspore product. So I’d like to use the belts. or get them repaired.

I’m with you if you find anything let me kniow.

Have you considered carpet tape? The stuff they heat up and press the seam together with?
