Also I wouldn't do all that drilling and tapping. It's a disposable motor anyway.
20 dollars for every size micro bit in increments of 100ths of a millimeter? Please do share, all I find are sets with increments of 0.03-0.05, makes for difficult jet work when all I can make is 63 65 73 75 83 85 93 95 ect... I must be missing something or that something doesn't exsist formally at 20 dollars unless you have an additional 200 to throw towards it
