I woke up this morning thinking about Ed Tosti's miniature clamps and one thing led to another.

 

I rummaged through the scrap spring box and made two sizes of clamp. one with a 1/16th steel rod  and one with a 2 inch finishing nail.

The small wooden block has a clearance hole for the steel rod, depending on the springs one has. the 1/16 rod used some old bic lighter flint springs

 

the bent finishing nail used a tension spring stretched out and then used as a compression spring/ These clamps close to about 1/64 but this design has a lot of possibilities for different openings like miniature bar clamps even

 

The short piece of dowel for the handle is a tight fit

I can see that i will be making a few of these using coat hanger wire as well. I made the bend short but I am posotive that a longer bent arm will also work.

 

These will be useful where it is difficult to use a clothes peg type.

By changing springs and being able to change the position of the brass nut makes these more versatile.

Eight more clamps for the collection I hope to use these for the planking of skipjack, when I get to that stage.

I thought I saw that design somewhere. They look alot like Cliquots clamps used in the aircraft industry. I have some like yours but their strength is too much to use for wood as they would crush your structure. You have a nice practical dsign there. BILL
