Hello Everyone,
Just to clarify any possible misconceptions, the "mimi mills" I will
have a kit for are the imported variety with the cast iron dovetail
(tilting) column domestically available from Grizzly, Micromark,
Harbor Frieght, and Homier.
My Z-axis mods involve, removing the entire "rack and pinion" stock Z
mechanism, supplying a modified spindle mount housing (the one
directly behind the spindle with the dovetail in it), and running a
ball screw down the @ centerline of the dovetail. I do not utilize
either of the torsion return springs supplied with the mills. The
headstock will hold it's position with the motors unpowered. As I
stated in an earlier posting (50) .024 DIA holes thru 1/8" THK oil
hardening tool steel with a single solid carbide drill bit takes a
rock solid and repeatable Z-axis mechanism to accomplish.
I plan to have a simple website by the end of the week. (time
permitting) I will include some prototype photos and better
descriptions. I will post a link here as soon as it is ready.
I Thank Everyone For Their Time And Interest!!!!
Regards,
Ken Cardolino
