Just swap one set of plastic gears with a set of metal gears and you'll have two motors each with a combination of metal and plastic gears, thus balancing them out rather than having one stronger and one weaker drive motor. Standard drills tend to come like this anyway; the metal stage is the one closest to the output shaft, and the plastic stage engages with the motor pinion.Quote:

From your existing drills. If you've got one with metal gears and one with plastic gears, that's six individual metal and six individual plastic gears you have. A standard drill gearbox needs six to run so use three plastic and three metal gears in one drill gearbox and use the remaining ones in the other drill gearbox. Voila :)
I like your thinking, i'll butcher them further tommorow.
