Needed a couple more clamps, here’s the prototype… All oak, saw the clamps that dakremer had made

I got around the “walking” issue by making the pad two pieces, each of which has a shallow mortise drilled into the center to fit around the “T” section of the T-Bolt. The handle is epoxied to the bolt, and it’s threaded through a t-nut. Works well thus far, we’ll see how the epoxy stands up to some pressure.

Nice idea. Similar to my cam clamps in build but more powerful. I like.

very awesome clamps!!!! that is a great idea for the pads, did is solve that “walking” problem??!! I haven’t made any new clamps since that first one I posted (I just haven’t had time) – mine worked OK but not the best because of the pad not working very great and I think i had the angle of the movable jaw a little too large so my clamp always lost its grip. Your clamp looks really nice – is it clamping down really nice, etc??? Very cool

Nice design. I’m anxious to see how they hold up.

in looking more closely at the diagram, I realize it should be put together in reverse, like this:

When the pressure is applied, having it this way locks the clamp head against the bar. Sorry for the early confusion!

FYI, another tip for longevity: it seems from the pics that the T-nut is installed on the outer side of the moveable face where physically it should last longer and have less stress on it if installed on the inside of the moveable face (on the pad side as opposed to on the star handle/nut side). As the forces of the clamping are acting on the bolt, the bolt is being pushed towards the handle side, if the T-nut is on that side, all that is really holding it is the threading and the glue, whereas if it’s on the inside of the face, what’s really holding it is the backing of the actual clamp face, and not really the threading nor the glue – which in the long run keep it from coming loose, or having a glue failure.

not neat-picking – just another thought ;)
