If you can't afford clamps ...

Just mucking about in the workshop. I needed some long clamps and felt stomach-sick at the price. So I went and got just under US$10 of meranti (Philipine mahogany, but not the good grade) and US$3 of brass rod. It was also an opportunity to practice some long disused skills, so I made them mainly by hand with hand-cut mortise-and-tenon and other bits. OK, I cheated on the sanding machine and bandsaw…

There are two long ones, just under a metre, and three at about 600cm.

I need to add some cork to the jaws. Otherwise they work OK. They won’t get a bone-crushing bite, but so far they’ve done all they needed to. Maybe, next time, I’d cut the shoulders back further as they sometimes interfere a bit with the work – you have to clamp at an angle. But heck, about US$140 saved.

Sitting here trying to work out how they clamp…...

I think the tongue is a cam lever? and the slot below it works as the part the cam pushes against?

I love the dragon head carvings. I always need clamps as well but now I need dragon head clamps.

Just guessing but I think if you rotate the tongue up, it pushes down on the lower jaw of the dragon.

I’m thinking maybe the tong is a cam that tilts the jaw so it locks ?

They are cam clamps or luthier cam clamps. The tongue applies pressure to the lower jaw as pinebox mentioned.

LeTurbo, nice job. Very creative for a practical tool. Love the designs.

LeTurbo,
Nice work. I like whimsical stuff. Did you work from plans?

Thanks all for the comments. Yes, they’re cam/luthier clamps. Slide the two faces tight together, flip up the tongue (or horn) and it pushes the animal’s jaw down. It’s an old design that’s been around since … oooh, I dunno, medieval times? No plans, BJ, I just studied some pics I found on the net. And yes, waaaaaaay too much time on my hands, bwahahaha! (Still, a lifecoach once said to me “You’re either earning or your learning”, so I put this down to honing some new skills, when I’m not honing chisels.)

Klemmsia make similar clamps, only difference being the bar is steel. As you say they were originally used used by Luthiers, I have used them and they are really easy and quick to use. And here’s the bonus for you, they retail at around £9 ($14) EACH. So well done.
