How big of a hole do you drill to do this? Also, please post your results, with pics if possible. I'm going to be doing this to a Space Duel CP soon and don't want to mess it up. Thanks.

It depends on the thikness of the material. My last panel I ruined three hole saws, they were designed for steel, but it was thick. Regardless, I was able to pound the carriage bolts down and tighten. You should have no problem.

If it's at all possible to cut an X then you will be able to tighten the bolt down into it creating a square.

To answer your question, yes. There are square BROACHES. Any industrial supply house (machine shop supplier) will have access to them.
To offer my opinion, as an ex-tool and die maker, drill them round and then file out the corners with a tiny file. I did 12 holes (a cocktail with three cp's) in 1/16 metal cp's in about 15 minutes. It's very simple.
Good luck,
John

Cool, thanks man! Can you just hammer these into the hole?
