Default Rong-fu (round column) mills

I used one for a while and wasn't highly impressed, 0.5mm accuracy was
about its limit. The quill was tilted, the table grooves had been
milled at an angle and the fine downfeed was almost impossible to
adjust closer than 0.005" because it shifted when locked.

It was a good-enough drill press and accurate enough for the
electronic prototypes and control panels I was making on it. It was
noticeably stiffer than my Clausing, removed metal faster, and had a
larger work envelope. The table travel was enough to reach any point
on a 19" x 5" relay rack panel. The 5" quill travel was enough for
what I was doing, as long as I pre-tested the reach of all the tools
the job would need. The face mill cut steel smoothly with the quill
fully extended and locked.

If your sundials are no more demanding of accuracy than control panels
it might be OK. It was NOT good enough to make close-fitting machine
parts, I took those jobs home to the Clausing.
