Thank you for the reply. I did indeed send them an email to customer support last night. Mush to my great suprise, when I opened my email this morning, I had a very nice reply from Jim Camp who is a customer service rep at Dremel.
In the email he told me that Dremel stopped making the 57-2 Scrol Saw in the 1970's and no longer have a owner's manual for it. He did give me part numbers for the 3" blades (8030 coarse and 8029 fine) and told me that the shaft out the side is a power take off for driving a sanding disc, buffing wheel and flex-shaft attachment. he then stated the following: Following are the
catalog numbers and pricing for these available accessories:
4214 rubber backing pad (for sanding disc) $3.25
4211 arbor adapter (use with 4214) $3.55
4227 sanding discs (4" dia. coarse, 6 per pk) $3.20
4228 sanding discs (4" dia. med, 6 per pk) $3.20
4229 sanding discs (4" dia. Fine, 6 per pk) $3.20
4235 3" buffing wheel (use with 4211) $3.20
990199 complete flex shaft assembly $33.45
I'm heartened by the fact that Dremel is still a company that puts quality and customer service at the front of their business. I can't wait to start whittling wood with the 57-2.
