I am still noodling about my ES4-B kit. I have been thinking about putting some switches where it would normally have knobs and visa versa. That leads to an interesting problem...

The pot holes come stock at 5/16"... that's a tad large for micro-switches, but I think I may have found some switches that have a bigger shaft that will fit...I hope.

The really tricky one may be where the three way switch would normally go. I'd like to put in a blend pot. Just got some...and they are the standard 3/8" shaft. That will be mighty loose in the giant 1/2" hole that is there for three way switch.

I know that making a small hole bigger can be tricky, but at least I feel like I know how to do that. I have no idea how to make a hole smaller in a piece of wood that is so thin. Hoping I can find a plastic spacer or something that will work...but wondering if others have found a solution to this problem already?
