Re: What is everyone doing, building, wanting to learn?

Hi John,

You developed the Sherline DRO and I started the Sherline Users Group
here on egroups. Your gantry mill sounds interesting, I am in the
process of building a table top bridge mill which will also use the
Sherline spindle and motor. I am looking to get a minimum work area
of 12 x 8 x 5 for x y and z respectfively. I for one would be
interested in seeing pictures of your gantry mill and hearing about
the major prolems you encountered in building it.
