Hi Kempe, you've caught us on the hop, so to speak, because the Scotty 590 was the last of the breed, and I have had no personal experience repairing them.....However, the cutter and roller clutches of the Model 45 have cork linings and both are glued in place. I suspect yours would have to as well.
From what I have read the glue to use is a good quality contact cement such as Bostik Gel or Bear Contact following the directions carefully. The reason your machine may have stopped driving initially, was most probably caused by the cork lining coming unstuck
Please let us know how you get on.
PS. as an aside, that plastic ring gear in your pic is notorious for breaking; with age they get brittle. Have you thought about replacing it with a metal one, whilst you have the machine apart?
