Turning C-clamps into half-clamps

Half-clamps work great for securing metal to the table after it is squared, allowing you to proceed to the next corner.

I call these half-clamps. They are half of C-clamps that were broken or have a bent threaded bar.

I cut them in half and welded a block on the clamp.

Half-clamps work great for securing metal to the table after it is squared, allowing you to proceed to the next corner. Just tack the inside edge of the block and let the backside float. It will tighten itself. To remove, just unscrew and bend it forward. Make sure you grind the tack off the table.

I also use them on outside corners when the sheet metal is on the inside of an angle and the pieces are too wide to reach around. Just tack to the sheet metal and put the screw on the angle. It will pull tight.

You can use these to push and pull material.
