I have seen cam clamps for benches of all shapes and patterns. I thought of the nautilus shell because of the golden ratio. Most cam clamps use a progressing curve. The shell is an easy to find curve on the internet. I have made 6. If they are used in a pair the need for a bit of friction is due. If used this way a piece of leather or some sandpaper should be applied to the edge of the pair. If you use the in a set of four they hold very well. I will apply sandpaper to two of them and keep the other four without. I like this for speed of clamping. If I am doing a lot of batch work this are a near perfect method of holding the piece. I have seen this shape used for holding rigging on sailing ships. The project is an easy build and fun to make.
I will also post this as a project for the Stumpy Nubs Jig contest.
Video as follows.

Thanks for your time!

Very cool Dave – I am kind of surprised how many power tools it took to create those hand tools clamps! :) Looks like they work great…..nice production!

Thanks Eddie. That is my favorite smoother. It was built by convict labor about 1900.
We will split the 10,000

These clamps really look practical and easy to make. I imagine they could also be used for edge clamping glued up table tops and such. As usual you are right on the ball Dave.

Thank you Steliart as always you are to kind.
Roger they are a breeze to use.
Go fer it Don, you and anyone else.
Thank you punk, my father would approve as well.
Good deal Smitty.
Mike I haven’t thought of that either. You guys have already started to use them in different fashions, now that is a good jig that is adaptable to other functions.
thanks guys.

Great job. I can see these being made from 1/4” ply, for thinner stock.

I think even I could make them successfully! All I would need to do is build a proper workbench with dog holes.

1/4 inch would work great for small items Randy. Give her a shot and tell us how it works out.
Thanks Pres.

Nice job Dave. You can never have enough methods of holding stuff. Variety is the spice of life. Have you thought of putting a bit of leather or rubber on the clamping faces?
