7/16" drill bit for riser bolt inserts?

Postby Kegan » Mon Oct 07, 2013 11:23 am

I've been using a 27/64" bit as per Bingham's jig and instructions for my three piece riser inserts, but it's officially given up the ghost. It got over heated and I can't even get it to hold an edge now. Anyway, I was wondering if a 7/16" bit would be alright to use since I can't find another 27/64" without spending a bunch of money on a whole new set? Is that 1/64" that important for a bushing that would get epoxied in anyway?

Help please?

Kegan my inserts fit kinda loose with the 27/64 bit, it may be too loose wih the 7/16, but then it may be actually fine and just leave more room for epoxy which may be good.

Every TD riser I have built has 7/16 hole in it. I have had 0 problems. The outside cut on the threads will be the same. 1/64th means there will be 1/128th less on the inner part of the threads--don't know what that is in 1000s but nothing to worry about. Just use some epoxy or Ca glue when you put them in.
