re: How many Shop Smith users do we have around here.

Not sure if they have those parts or not, If you have the manual with an exploded parts list, make contact with them giving them the part number. I had to order a new manual for my 500, and it has been very useful since. I was surprised that it also included some good tune-up information that I was unaware of. It seems like they have the manuals for model 10 now that I think about it. So they may have the required parts, or at least some that may be interchangeable.
