Re: Oversized (80+) jets, where or how?
Or.. You could just buy a drill set with every size for $20.. Even HF has a micro drill set for $4 but not many different sizes. Only thing is that these micro drills like to spin in excess of 15000 rpm, so whatever you got that spins fast use it.
Also I wouldn't do all that drilling and tapping. It's a disposable motor anyway.
