Picture of Pad for a C Clamp
C clamps are great, but they can leave unsightly dents unless used with a piece of scrap wood to prevent those dents. But, a piece of scrap wood almost requires a third hand to keep it in place while you hold the clamp and tighten its screw.

This Instructable will show a simple way to attach a pad to a C clamp to eliminate clamp dents and also the need for a third hand.

The photo shows a piece of walnut clamped to a jig I made for cutting 22.5 degree miters to be used on some flag cases I am building for an organization that will sell them to support its ministry to homeless. 

Step 1: Cut a circle

I used a holesaw to make a round piece from 3/4 inch plywood. The diameter is about 2 1/4 inches.

  • Holesaw
  • Electric drill
  • Twist drills
  • Angle head grinder with cutting wheel and grinding wheel
  • Dremel tool and cutting wheel
  • Screwdriver

  • 3/4 inch plywood
  • Sheet metal
  • #8 x 3/4 inch screws

Thank you, Osvaldo.
Well I know what I'm going to do, I'm going to glue that dude to my next project with the squeeze out, my problem is I never think about these matters until the glue is flowing
Btw good idea!

Thank you for looking and for commenting. Rather than simple plywood, you could make the disc from a shelving or countertop material that has a thin plastic laminate on one side. The laminate will not stick to excess glue. Or, you could tape wax paper over the surface of the plywood disc. Most of the time this clamp will be "around the corner" from glue squeezing out of a joint. I would want to avoid getting glue on the surface of the disc because I would absent mindedly transfer the glue smear to the next nice piece of wood.
