I had to buy a new set - and I chose carefully. The ply is in metric
and has odd dimensions. Be sure you measure and check your set.

Glad a job I got paid for a new set at the time.

Also advisable is a set of plastic shims. Lee Valley sells a set that has
slots cut in them so the arbour nut doesn't have to be completely removed to
add or resize a shim.
