I have lashed up a grinding machine using a diamond cup wheel to touch up my carbide lathe tools but the nylon camera bag strap that I have made the drive belt from is far to thick and the glued area where I joined it makes it "lump" over the pullets ( 22m dia. and 50mm dia).

My question is, do any of you know of a thin, tough and flexible material,preferably something that I could reinforce by stitching (say 1/64" – maybe a little thicker) in sheet form that I could cut and join to make a drive belt approx. 1" wide? I would need a length of about 18" to form the loop.

Why don't you use a toothed belt turned inside out ?

Best candidate for jointless flat belts is PolyVee turned over. It will run much quiter and smoother than the back of a timing belt.

Suppliers stock the belting as a wide band (500mm?) and slit it to suit the number of grooves on the pulleys. I have one with only 3 ribs so its less than 8mm wide

It will probably offer more grip that way round as well !

Flat belts should be available from any good bearing / transmission supplier.

There is a heat joinable belting, I think it is used for tool post grinders, and other high speed applications, I think its best to give the supplier the measurements, and let them join it, I think it's more difficult than the round belts. Ian S C

Redthane round plastic belting.Heat up a broken hacksaw blade or old knife,push the two ends onto the heated blade pull away and push the two melted ends together, must be held in line for 5 or 10 minutes leave over night.Next morning remove plastic flashing with a sharp knife and smooth up with some course sand paper. Very quiet in operation. I believe they make a Greenthane as well its small diameter, Ted
