I picked up a 1/2" Craftsman ratchet that has quite noticeable play between the knurled thumb wheel and the ratchet body. It doesn't appear abused but I was wondering if anyone has ever used a thin round shim to take up this space? I thought i have seen someone on a discussion mention they used a shim in an old ratchet to tighten it up. Is this possible or should I just use it as is and don't worry about it? I cleaned/lubed it and its perfectly functional. Do hardware stores carry such shims of different widths. I measured the space in the picture at 45-50 thousands. Thanks for your ideas/thoughts.
