I just finished building clamping cauls and am ready to glue up a table top. I do not want the cauls to be glued to my top. If I use Johnston’s past wax on the cauls will that effect any finish I apply to my table top.
Thanks for your help!!!

Get clear packing tape and put it on the side that touche your product. The glue will not adhere to the packing tape.

Note this also works with any type of clamping block you may make/use.

Thanks Brian, Does the packing tape need to be replaced after repeated use? if so, Does it come off easy or is it really stuck to the jig?

I have had the original packing tape on mine for ages and no problems.

Thanks Jerry, I have some scotch clear moving and storage tape. Is this what you are talking about?

I usually cut notches in the cauls where they cross the glue lines to keep them from spreading the glue out onto the surface of the boards. Can also get in there with a narrow chisel or scrapermebobber to get the glue off before it fully dries.

Don’t you want the cauls pressing right on the joint to keep it flat? I suppose if your boards are flat it wouldn’t matter.

And the tape lasts quite a long time. Just get a roll that is wide enough you don’t have a tape seam down your caul. Otherwise any clear packing tape works as far as I know. Saran wrap also works, but be careful as it tears easily. Tape is obviously superior because it is sticky and holds itself in place.

I finish the pieces first and then glue them up. :)

Paste wax will repel all stain finish and cause a bad bond with glue.
