Well, I tried tapping the threads in the blade holder, used a new screw, and the same thing happened.. stripped the threads on the new screw. I took the blade holder piece off the saw and noticed that it had been very poorly machined right from the factory. Rather than trying to order a new piece from SKIL, which probably would take several weeks to receive, I decided to try another route. I took the blade holder piece to the store where I bought the saw along with my purchase receipt for the scroll saw, and spoke to one of the sales associates there. They had my same scroll saw on display, so the salesman said "Let's have a look at the blade holder on this display unit". It looked perfect, with nice clean, tight threads for the screw. He said "let's just exchange pieces and we can return this display unit back to the company.. no Problem". Whew, problem solved, thanks to good customer service at the store. I'm scrolling once again, only now I'm scrolling with a smile on my face and whistling 'dixie'. Once again, thanks to all of you who offered suggestions and tips, you're a great bunch (of bananas) LOL.
Regards,
Trevor
