There are never enough clamps in my shop and a while ago I decided to expand my collection by making a bunch of these cam clamps. They work very well and exert more pressure than imagined. Though not in the same class as G clamps, they are useful for light duty jobs. I know they can be bought out of a Woodcraft catalogue, but we are not fortunate enough to have them here in South Africa. Making your own means you can size them to your requirements. Besides your time, they cost next to nothing. Mine were all made from off cuts. If you are short on time, switch off the TV!

The one in the picture is a baby and only measures 6” x 3”. The shaft is made from African Blackwood and the jaws are Candlewood. The jaws were made in two halves with a rebate and then glued together. Off course you can also do solid jaws and cut through mortises. Doing them in two halves is easier and quicker, epecially if you want to make a number at the same time. Lengths of 1/8” brazing rod act as rivets to hold all together and are also used for the pivot pin for the cam.

They can be made in any size and I’m sure any hardwood will do. I would say the only important thing is not to use a brittle wood for the jaws.

I really like the cam action on this clamp. Simple yet elegant design and carried out very well in the construction.

Not only functional, but it looks great! Not often you see blackwood used for something other than accent work. Well done. -Richard

Good job for nice clamps !
Clamps are ever the problem in a project, not enough or not the good size.

Hey LJ’s! Thanks for all the compliments and real happy I could inspire some guys to add the idea to their lists. That is after all the point of the exercise.

I have some of these (store -bought) and love them. Planning to make a few for a more deep-reach clamp with longer jaws. The cam action works however far out you put it, so there really is no limit as long as your workpiece is elevated during clamping. A piece of square cork inside the jaws helps nicely, too. Thanks for the photos, DIV.

Hi there Div, great looking clamps,very nice craftsmanship. I have always liked the simplistic ,yet effective, design of these style clamps. I have seen them used a lot in fine instrument construction and was always considering purchasing some,but now(with Your inspiration ) I think I just might try to put some together myself ! I do have one question about the cam design,how did You figure out the right amount of offset for the pivot pin or is it an trial and error process ? Anyway, thanks for the post and great job once again!

Very pretty!

Any suggestions on cutting better cams? I’ve done a few for some non-cam clamp projects, but always end up with the sandpaper and something that’s not as round as I’d like…
