Re: [CAD_CAM_EDM_DRO] New Mini mill/drill

Search the web and you can find more on this mill. I think it started life
as an "Atlas". The Grizzly supposedly has improvements over the Harbor
Freight and older Atlas unit.

I've had the Grizzly for about a year now. I also have a Sherline Mill. It's
far and away better than the Sherline. It isn't as easy to convert to CNC as
the Sherline. I haven't converted mine to CNC yet but plan to this summer.
The X and Y will be fairly easy, the Z however will be more difficult.

The mill does come with a drawbar to keep your cutters in the spindle. It
also comes with a nice toolkit to fit the bolts on the mill.

later,
Larry E.
