Lots of main spring vises, should be able to buy almost anywhere. But, how many of you have a frizzen spring "cramp"? I
bought several from Dave Motto years ago. No moving parts. It is made from 1/4" round stock, bent in such a manner that
it slips over the spring, and the lower leg is about 4" long. You merely slip it over the spring, put a little upward pressure on
the lower leg which will take the tension off the screw, then merelh remove the screw. It is so simple it will make you mad at
yourself for not thinking of it.......Don
