I am busy with a drill/mill tool to be mounted on the place of the toolpost of my lathe



I made a 3:1 reduction with pulleys and a belt of my old Mugen MRX4 powering an ER11 chuck with an 8mm shaft. This construction will have less play and is more precise than a chuck with a direct mount on a motor shaft.
And I used a thrustbearing to take the press forces.

In this way you can use a simple 550 brushless motor
