Several woodworking retailers sell their versions of a Sacrificial Fence Clamp, for holding a scrap of material to your table saw fence in order to do cuts like tenons and rabbets. These clamps often sell for close to 10 bucks each. Here’s a version I made from a squared U-bolt and some shop scraps.



Standard square U-bolt from hardware store. Costs about 4 bucks. Wing-nuts are about 30 cents, or use jog knobs if you have them





Cut the U-bolt in half.





Sand off the sharp edges.





Fashion together some scraps to form an L that is as long as the width of your fence and drill a whole all the way through.




Finished product.





Two working together to hold some mdf square against the fence.





A video if you prefer…

Makes perfect sense. Simple, cheap, and it works. Did you have to bend the short end of the u bolt in a tad to put pressure on the center of the fence or did it just flush rite up?

This is pretty neat. I have some of these clamps but this certainly looks like an economical alternative.

Hobie, I had to bend the short end of the L because it wasn’t manufactured square.
A couple knocks with the hammers and it was perfect. :-)

Scott, when the Rocklers are on sale with free shipping (now!), it’s almost silly not to buy them. But these are done an I didn’t have to wait…. although it is nice to see that UPS truck pull up, huh? :-)

Nice idea! I’m not sure it’s worth the effort to save $15, but I like your ingenuity.

That is awesome. I was considering purchasing a set but could not bring myself to fork over the money for them. Looks like I have a project for this evening.

Thank you very much.

Great idea. In Canada I couldn’t find these and ordering online from Rockler cost a fortune in shipping. Thank you now I can make these and save the headche.

Great idea. To bad they already have a patent on them, you’d be rich. Nice job, thanks for sharing with us.

I know this is an old post, but I have been keeping it around in the back of my mind for quite some time, and finally found the right U bolt at the hardware store to build a couple of these myself. Great ideas never die!
