I was looking for a clamp that could hold a glue up of two 45 deg strips of wood to make a block. Basically two triangles glued together to make a square. All the woodworking site searches produced nothing. Then I came across these clamps on a welding website.

I ordered three of them from my local welding supply store to see how they would work. The man at the supply store had never seen them, apparently they have a patent pending. Took them home and tried them out.
The clamping pads swivel from about an 80 deg angle to more than 180 deg angle. Also the pad heads are locked inline with the clamp, but can be unlocked to swivel 360 deg. The clamping mechanism is on the same principle as a vise grip, having a threaded adjustment for closing or expanding the jaws, and a quick release lever.
When I clamped up my triangle strips the swivel head pads centered the two triangles together and put the clamping pressure directly over the angled center glue up.

After clamping together maple & purpleheart, walnut & purpleheart, and maple and walnut, I planed them down to size being careful to keep the 45 to the corners. Then glued up the strips like I do for an endgrain cutting board, cut to thickness, and flipped and rolled until I was happy with the pattern, glued again.
The board in the pictures was my attempt, I think it was successful.

The website I have posted has some great clamps that can be used for all types of applications, I am going to put rubber pads on the clamping surfaces to protect the wood, but other than that, these clamps are an awesome solution.

Larry,
There is a distributer in Australia-

I think I paid about US$16.00 each and US$11.00 each for the smaller size that I ordered later.

Hey Lisa, I’m going to ask a seemingly silly question, but could you have made some V-blocks and just used regular clamps? I mean the price is pretty good and these would defiantly be quicker then trying to place some V-blocks and clamps so I can see the appeal and could use a few of these in my shop too. Just a thought.

Chris,
I tried V-blocks. The problem I was having was keeping the opposing V’s squared. When I would glue up, the strips would have a tendency to skew, then they wouldn’t plane square. Even used cauls to keep opposite corners in place, it was just cumbersome. Tried making a jig, got frustrated with it. These clamps do all squaring in one shot. I guess it was for ease of use, and piece of mind that everything was squared.
It was an investment, can also use these clamps for long curves, rounds, flats, and tapers.Different head pads can be attached with ease. Can be seen in accessories on the website. Very versatile clamp.

Looks like it. Well, I’m glad they work so well for the application you need. I can see how they can save a lot of time and frustration.
