Good luck
How does one get a .0005 interference fit with the replacement gear? Are metric reamers sized .02mm under readily available? Where would I find such a tool?

Basically, I got .7 mod gears from PIC-Design to mate the Bosch to the rest of the gearbox, but I am having fits trying to get the spacing correct. No such problems with the 20dp gears from Martin Sprocket...
