Re: Low Cost Planetary Gearbox Source...

i would say for us so far the hardest thing about these trannies is getting the gear off the FP motor. I ended up chucking it up in the mil and milled the gear of. As for pressing the new pinion to the shaft we haven't done it yet. But the plan of attack is to make a spacer from the motors that come with the transmissions that fits between the pinion and the motor casing, then use that same spacer on the FP motor. We are planning to heat up the new pinion and thermally bond it onto the shaft so there is less of a chance of bending the shaft on the FP while applying it. I will write up an after thoughts post after we are done.
