Hi gang : a dilemma - After an excellent barbecue and many drinks I innocently mentioned to a very good friend that I had a need for a scroll saw. He, being the great mate that he is, informed me that not only did he possess such an item, and one of great quality, but that furthermore, he would happily part with it for a pittance. Upon my enthusiastic enquiry he told me that it was made by a Swiss company called Jet. My interest mounted. I should state at this point that he is, despite many other attributes, not a woodworker, and is inclined to unwarranted excitement when exploring a well-known auction site. Net result, I now possess a very cheap Jet scroll saw, but sadly, one at the dodgy Chinese clone end of the range. Not only that, but I've discovered that one or two parts are missing, in particular the drop foot/hold-down clamp. Could anyone tell me how essential this is, and if it's possible to obtain as a spare part? My optimism is now waning, and I'm beginning to wish I hadn't mentioned it. Grateful for any help.
