Press Fit Tuner Bushings

[low end fuzz]

i tried these stew mac cheapies and decided to put them on a new headstock;

they are the ' adjustable tension tuners' w/ elephant ears; fyi;

they are multi screwed in the back, with press fit bushings;

my original plan was to drill for the posts, fill in with dowel, drill out for bushing and knock out the dowel;

like ive done 'guitars' before;

i have the post holes drilled, but the bushings are 23/32; and i want the holes a tiny bit smaller for the teeth although, a layer of finish might tighten them up just fine;

but i dont have a 23/32 bit; the closest thing i have is a 3/4 (i forget the name , but its the scary one w/ 3 points haha) i went looking for something at the stores but cant find anything that looks like a good choice and my reamer is to small for these 'giant' bushings.

any ideas?

thanx
