New 4th Axis Shaft Purchased
2011-03-25_1314.jpg

I used this ER32 with a 3/4" shank. I used Stepper motor with 495 holding torque and 2 : 1 Timing pulley ratio. Added the Taig lathe chuck to fit the 3/4" ER32 collet. This way I can remove the Chuck and use the ER32 collets.



The pictures will show the 4th axis parts.
