Fixing a Slipping F-clamp




Introduction: Fixing a Slipping F-clamp

About: I'm a elektromechanic, who likes to create, build, repair various items, tools, etc. And I tought, why not share some of my projects with the rest of the world.

Over time, and a lot of use, most F-clamps start to slip while tightening. If you use cheap clamps, as I did, you can have the same problem.

In this instructable you can read/see what you can do to fix the slipping.

Step 1: What You Need

All you need is a triangular file.

If you have a bench vise it is the most easy way to work. If you don't have one, you can tighten the F-clamp to a solid piece of wood or metal, so that the clamp is horizontal.

Step 2: Start Filing

Put the F-clamp in the vise and start filing. Just deepen the grooves in the clamp. I did 3 strokes in each groove.

As soon as you've finished the outer side of the clamp, just turn over the clamp and do the inside as well. You will notice your clamp has more grip after this filing.

All needed to get some more life out of your F-clamp was 5 minutes of filing, no extra cost.

    I've also had success using a hacksaw on a really old clamp. But my new bar clamps have bigger grooves and a triangular file might do the trick since they are starting to slip. Thanks for the idea!

    I have even cheaper F-cramps where there are no grooves at all on the back edge of the spine. Yet. Thank you very much for the inspiration to go and fix that. :-)
