Hi Jim,

Yes. this is for our friend Jim Jakosh, as he requested, sometimes we have to get what we ask for. ;-)

Nice work on that horse, Mads. That is such a simple and effective holding device! I see you have a cam clamp that clamps with the cam out at 90 degrees. Can you shoot me a sketch of how you made the cam—mine go all the way up and I want to make 4 more but not before I get the cam right.
Cheers, Jim

Here a link for Jims cool clamps: https://www.lumberjocks.com/projects/409803

So here you go Jim, only I did not make them… I simply bought them in the local DIY, some years back:

I hope it can be usefull for you my friend.
(Or anyone else who sets out for making their owncam clamps).

Best thoughts,

Thanks, Mads. Do you have a shot of the cam? I made mine like one on you tube that had dimensions but they put the pivot hole ahead of the center of the radius and off center by 1/8” and mine close with the cam at about 30 degrees from the center line of the clamp. I want them to close tight at 90 degrees like yours. It seems that the pivot hole has to be directly behind the center of the radius at the end of the cam for it to close tight at 90 degrees.Is that right?

cheers, Jim.

Jim,
Wouldn’t it just be a matter of putting the largest cam diameter from the pivot directly on the end of the lever?

Kind of…It also depends on where the hole is in the clamp. And also the placement of the hole in the clamp should not make the cam engage when down all the way, and should be a gradual tightening that won’t force it backwards when you release your hand.

Hi Jim,
I’ll try if I can take it apart and take a picture.
Just home from Rome today, so I will be in the shop soon.
