Don't I know it... I've got an Expo Reliant Minidrill. It's not too bad, but
the bearings are lousy. If you run it at any speed, you can see the
unevenness in its motion - the drill bit seems to "bob" from side to side.
This in turn causes the bit to vibrate, then the drill and stand, then you
get a horrible noise as the stand starts resonating, then finally.. boom.

I really need a new drill - anyone got any suggestions? I'm thinking about
getting an Expo Zircon primarily because I've already got a stand that fits
it. The specs are on <http://www.expotools.com/> (IIRC) if anyone's
interested.

I was going to build a CNC myself, but getting the parts seems to be the hard
bit.. that and actually designing the thing.

Later.
