I donated this drill press to Noisebridge a while back, so will comment
on it a bit... This is designed to be a wood-working drill press, and
as such is somewhat different than a general-purpose/metal-working
drill press (it's ok for drilling metal, but more for smaller
diameters -- doesn't go quite slow enough for large bore cuts in
hard materials). Rather than having a table that moves up & down
relative to a fixed head, the head moves up and down relative to a
fixed base, or "table". There's a crank on the side of the head for
raising & lowering it, just be sure to unclamp where the head mates
to the column before adjusting, and re-clamp after making the height
adjustment. The whole column/head assembly will pivot on the socket
in the base, just be sure to unclamp/re-clamp that union before &
after making any adjustments using the clamp knob in the base near the
column. And if the drill bit is coming down in a region of the base
that is not where the slot is, and it's a through-hole you're making,
please use some sort of consumable backing material between the base
and your workpiece.
