  • Miniture machinist's clamp

    Hail and good day

    Do any of you folks have any designs for miniture machninst's clamps or any other small clamping devices? I have an occasional need for them and have sold a few over the years. The smallest I have build are about the size of a postage stamp. Used .125 key stock and 2/56 threaded rod. I would appreciate any and are willing to share.

    Thanks

    Russ

    Guy Lautard has dimensions for a range of clamps in one of his "Bedside Reader" series.

      The article is in Bedside Reader #1, pgs 149-153. He has sizes from 1 1/2" to 5"; you could scale from those to your little guys, I think.

        Guy's "stroka' genius file rack book also has a spring loaded c-clamp that is cool. Lee Valley Tools sells minature brass clamps as well.

          A common problem that arises when using parallel clamps (I assume that's the kind under discussion) for driling is that after one has clamped the work to one's satisfaction it is discovered that the clamp is in place right where you want to put the hole. Try this: grind or mill a slot (1//4" long?) down the center of the clamps that will give you a two-tined fork shape. Now you can drill thru the clamp. Clamp holds just as well as solid style.

              Thanks, I have the #1 Machinists Bedside Reader. That section is really good as I make most of my own small tools. I was looking for an unusual design to try out. Russ
