Sorry for the delayed response. Thanks for the advice, unfortunately, I do not believe Surplus Centre had plain beveled gears in the 2009 catalogue. (Just reduction gearboxes)
Now I have yet another questions for the vets out there. As I said, I have two drill motors which have a very nice reversable speed control "throttle" which would be perfect for rc steering. The only issue is that the pot and switch for each one is of course in a little tiny black box connecting to the motor leads. How can I basically make these speed controllers remote-controlled? —Mike Måne Message sent by way of mobile device On Aug 10, 2009, at 9:28 PM, jvragu47 <[email protected]> wrote: > > Mike, > What you need are beveled gears, such as Joe used inside of the > Hetzer. > Surplus center had them for awhile, check their site. > > > > > On Aug 9, 2:54 pm, Mike Mane <[email protected]> wrote: >> As you mighy recall, I have been planning to build the M4A3 (76mm) >> Sherman.
