I contacted a local belting company who I deal with. They recommend
replacing the leather belts with a 4ply Transmission belt.
I had them quote on the following belt.
3/4" x 53" x 3/16" with clipper lacing (Steel lace). Price $20 CAD
($13.00 USD) plus shipping. (You can specify any length)
If you would like to have an endless belt or a belt prepared for
gluing, it is the same price. They can also provide a special glue for
this belt.
The Company Name is Associated Industrial Rubber (902)468-1202.
They are in Nova Scotia Canada. They will ship anywhere. Make sure you
ask for Angus MacDonlad.
Hope this helps.
