I don't know if this is the right place to post this, if not please move it where it belongs to.
I have a clamp that is about 35 years old and it has started to get loose.
If I clamp something to glue it normally it holds but if I clamp something to work on it i.e. planing, it gets loose.
Is there any solution different from drilling evenly spaced holes on it and putting a pin?
I do not want to discard it as it is in very good condition.
Any info will be greatly appreciated.
