The thought was to use the power of the Chiaphua to suppliment the drill motor/gear assembly in low gear only. To do this we would gear the Chia down about 10:1 and direct link it's output shaft to the output shaft of the drill assembly (probably via sprocket gears and a chain).
The rub comes when we switch the drill motor into high gear without changing the gear ratios to the Chia. Now the Chia is spinning well above its free load rpm. We are assuming we don't need any contribution from the Chia in the high speed mode, but are wondering if anyone has experience with the resistance we might expect from the Chia in this mode, and if there is some other, obvious or other, reason not to use this configuration.
I'm afraid the 2-way operation of the motors would make difficult a racheted gear or one-way slip clutch. We're on a very limited budget and without a decent machine shop and so are, at this point at least, trying to torque-up in low speed mode w/out building an external shifting mechanism (other than the servo swiching of the drill gearbox).
I also just saw the previous thread. Thanks for the link!
