Cam Clamps 8x8

I made 2 more cam clamps out of quarter sawn white oak. I needed bigger ones so these open to 8” with and 8” throat. They were made with a one piece solid body with a groove in the end for the bar and then the end was plugged with a solid piece. That is what I made that tenon jig for! The bars are 1/4” x 1” aluminum.

The cams have the pivot hole directly below the center of the radius so they clamp tight at 90 degrees.

They are finished with Danish oil and then buffed and waxed.

Cheers, Jim

Love ‘em JJ... but without further details and measurements I can’t determine whether they are metric or imperial…

Thanks for all the nice comments.

Hi LBD…....they can be either. Like a metric crescent wrench!

Hi Joe, yes it got duplicated and I’ll see if Cricket can remove one of them. Every time I post anything, I get a 524 error, but the post goes through. Last night, I got that error and it didn’t post. I went through the process of posting again and it had all the wording there and said it did not post because the photos were missing…so I loaded them again…and then I got two postings!!!!!!!
I don’t have any detailed drawing. I just drew them out on the wood. I did make a cardboard template of the cam, though.

Hi Ivan, the deep reach is really nice to have .
cheers, Jim

Sorry J’J’... Just me trying to be “funny”... looks like I was trying... very trying!

I was actually digging for measurements, however, afterwards looked back through you projects and saw a post on a previous build that had measurements… while I appreciate those measurements may be purely arbitrary, initial measurements are always a good starting point first time up.

Thanks, Bruce and Pottz!!

Hi LBD. I knew that ,but if you want dimensions on these parts I can measure them and post them. The cam was the thing that had me puzzled but after a few tries, I got a design that works real nice and made that cardboard template of it. I used tenon jig and a milling machine making these, but if you make them out of 3 pieces, you can use your table saw, band saw and drill press to make them. They don’t have the pressure of a C clamp but enough for holding parts together for gluing.

Cheers, Jim

How many clamps does it take to make these clamps?

I think you hit upon the ultimate WW accessory to produce, an infinite demand for clamps means an infinite demand for your talents 8^)

Keep them coming Jim!

Hi Bruce. This one took only one clamp for the inserts behind the bars. The nice thing about these it that you can make the throat to whatever dimension you need !

Cheers, Jim
