Having passed to the editor some Htime ago, an earlier article on workpiece clamping, the suggestion came back that a constructional article for a low profile clamp similar to that shown in Photo 1 would be worthwhile for the magazine. Having agreed, it occurred to me that there would be other ways of performing the same task and decided to include some alternative designs. Not having researched the subject in great depth for this article, I cannot be sure whether the designs I am suggesting are original. Certainly one design is available commercially (one version under the trade name "Mitee Bite" if my memory is correct), and I suspect that at least some of the others are ones that I have seen previously, which have now resurfaced as a result of my considering the possibilities. I am as a result including designs for the five clamps, seen assembled in Photo 2 and dismantled in Photo 3. These all use the same basic principle of a T nut that is fixed in position using a grub screw, Sk. 1 should make this clear.
