Is this right:
Chiaphua= 5500 rpm
Drill (no gearbox) =about 19000
The ratio is about 3.5:1
I can't seem to find the rpm of the drill w/ gearbox
I think by having the drill gearbox it will eliminate more gears. I am trying to make the gearbox as simple as possible. Lighter the better
Sorry if im sounding stupid
