I made these in anticipation of someday being tasked to repair cracks in violins. I made them from a, (or a few) Pend-A-flex hanger frames (one is shown above framing the three clamps.) The U-shaped part is threaded on both ends, while the straight bar has a threadable through hole in each end. I simply bent the frames into a C shape as small as possible on my machinists vise and fit either a 1/4 inch bolt or a #10 bolt in an appropriate hole. The smallest of the three I had to flatted then end to drill and tap it. This is a start, but ‘ll be building a collection of these in various sizes. You can’t have too many clamps!

[Below]: The sort of oval shaped one with the two screws is more of a guitar bridge clamp, but it could come in handy regardless:

Thanks Candy! Sometimes I think a shoestring budget is what gives me what little cleverness I have. I’m hoping this series will be a resource for others who may follow my path. I’m told there aren’t an overabundance of people who can do what I’m learning.

Unfortunately there’s at least one tool I’ll need to buy as it’s precision engineered. It’s also (to me) a bit pricey. When I get it, I’ll be making a case to keep it in for safety.
