Lee I decided to take your idea with the holes and run with it, hope you don't mind.
I decided that all new clamps was too costly, even the materials and time to build them myself was too much. So I went with 1 1/8" holes 2.250" deep, every 4" from center and ended up with 15 holes total 7 on each side plus the one in dead center. This should more than be enough to get the job done and I can use standard 4" and even 3" clamps.
For the layout I set my 6" square to 1.750" and traced a line following the curvature of the caul from the top side, then measured every 4" out from center. That way I was sure there would be plenty of meat to prevent breakage of my caul when I tighten down the clamps and I can still use a 3" clamp.
The black clamps in the pic are 3" and the red one is a 4" clamp. Both will work just fine and when the tool sale comes to town shortly I'll pick up some more. I've almost got enough but some of them are old and should be replaced anyway.
Here's the pics of the final product.
Does anybody else's Father own a set of Forstner Bits?? Mine does and these things are like hole saws on Steroids!! Wow!
Much, much nicer than hole saws and I was able to do it all on the drill press. Made some really nice, smooth, pretty 1 1/8" holes.....no sanding required. :cool:
That's it now, this Project is Complete!!
Hope you all enjoyed my Caul Build, thanks for watching!
