I am loving LJs. Lots of quick help out there. Here’s my next question:
I’m working on a franken – Rubo / New fangled styled workbench. It will have the pipe clamp workholdings like the new fangled with the thick heaviness.
I’m using a solid 5” thick top and want to drill holes thru the center at 6”/6”/6”/6”/12”/12”/40” to put in 3/4” pipe clamps. I’m trying to drill the right sized holes thru each layer of the lamination of the top. But the OD of the black pipe is just larger than 1 1/16 inch. I can’t find a drill bit that will make this fit snugly, but not tight. I used a 1 1/8 inch paddle and forsner bit, but they both are a bit sloppy.
How does one make a properly sized hole when there doesn’t seem to be a drill bit to fit? I’ve used the “wiggle the smaller paddle bit around in the hole to make it a bigger hole” method, but I don’t want it to be sloppy. Several layers with the same hole need to be glued together and lined up.
Thanks for your help.
