As part of a favor to Justin (JUZWUZ), I have choosen to make a couple bases out of 6061 Aluminum to support a VEXTA stepper motor with a Harmonic Gear Reduction unit. The Harmonic Drive has a Ratio of 1/50, with a max Torque of 55Kgcm.
After I make the aluminum support bases, I will make an adapter plate to go between the Harmonic Drive and a 3" 3-jaw scroll chuck.
First I ordered two blocks of aluminum, 4x4x4 1/4
The next step is to machine the cube perfectly square, so the 4th axis motor will always be paralell to the base. The project begins here!
