Shopmade cam clamps made from scrap 3/4 inch stock after a Fine Woodworking article, and several YouTube videos. The maple bodies are pinned to 1 inch by 1/8th inch aluminum bar from the hardware store on the fixed ends with 3/16th x 3/4 roll pins. Some designs do not fill the bottom slot but rely solely on roll pins to bear against the bar on the movable jaw, but I had a hard time placing the pins to tight tolerance and decided to infill the mortise. I added the decorative hardwood scales in walnut, jatoba, striped mahogany and lacewood to dress them up a bit. Jaw faces are just chunks of cork craft tile as used for bulletin boards etc. The movable jaw is retained with a Pop Rivet.
Finish is BLO/MS/Alykd varnish wiping oil.
I was able to make four sets; two long and two shorts from the 4 foot aluminum bar and a handful of roll pins, total outlay of about $15.00. They are light duty, but handy and quick to set.

I’ve made a bunch of these and they’re great, but yours are much nicer with the scales. All tools should be decorated!
Tip: don’t try to apply too much pressure as the handle will break at the pivot.

Those are nice looking clamps. I must say that I have made similar, just not as nice.
I wonder how much clamping pressure you gain using aluminum for bar stock over wood?
The other thing I noticed is your cam lock if over centered will release pressure it moved too far. On mine the cam is more teardrop shaped and will continue applying pressure until the lever hits the clamp.

Very nicely done. Sure is better that the outrageous amount of money they want for clamps.

Those are great, Doug! Clamps like this have been on my to-do list for awhile, but just haven’t risen to the top of the list yet.

Since most of my clamping is light duty, these would be a great addition to my shop.

Mel, I followed the plan from the March/April 1996 Fine Wodworking for most of this and I totally agree. If the bug me enough, I may swage out the pin and replace the cams.
That article mentioned the tendency to crack at the bottom if at least 3/4 inches of stock was beyond the bottom of the bar, but nothing about the pivot point and I have noticed a crack on one of them there. Fortunately I am drowning in little bits of stock, so I may tinker with a wooden bar and cams…

Douglas, I have been meaning to make some of these fior a while. Thanks for the inspiration.
I love the way you dressed them up too. I usually end up doing the same thing to my shop projects.
I can’t leave anything plain!
Thanks for sharing
Great job

Nice work! With the cost of good clamps, I wonder why more of these aren’t shop made?
