Hello Archie,

I am using the Sherline supplied dual axis 130 oz in steppers on all
three of my Sherline 5410 (metric 5400) mill axes with rapids at 20ipm.
I plan to move two of those motors to my Sherline lathe, whenever I get
around to CNCing the lathe. At that time I want to put more potent
steppers on my mill.

I don't need to rapid faster than 20 ipm. I just want to be able to
remove more than 4 cubic inches per hour of 6061 aluminum by taking
bigger cuts or increassing cutting speed to something closer to 20ipm.

Are your 280oz-in steppers NEMA23? Are they dual axis? Where are they
available?

Any idea how long would it take you to mill out a 1 x 1 x 1 inch pocket
of 6061 aluminum with a 3/8 inch diameter endmill?
