I have a Delta Scroll Saw that I bought new mayby 12 to 15 years ago. It is the 18" with the floor stand. Model 40-650C. I called Delta today for some parts for the top blade holder but they told me they changed the clamp a few years ago and no longer have any spare parts. Delta is now in Halifax and not Ontario. Does anyone know of another place where I can get parts. I asked the guy if I could install another model clamp but he didn't know. Not very helpfull.
