A foot switch on a drill press makes a great deal of sense. I just
picked up another VFD from Ebay, and this one is going on my big
Rockwell/Delta 1hp drill press, with a foot switch hooked to "run"
That drill press WILL hurt you if one hangs a bit, with its 3MT
spindle taper and that 1hp motor

Political Correctness is a doctrine fostered by a delusional,
illogical liberal minority, and rabidly promoted by an
unscrupulous mainstream media, which holds forth the
proposition that it is entirely possible to pick up a turd by the clean end.

I was reaming a hole with my DeWalt 18v. drill today when it caught a burr
and just about hurt me. Those dang things with moving parts and torque have
no respect for soft old flesh.

In my younger years, I took enough shortcuts to realize that I can't take
shortcuts. The trick is not getting too banged up learning or even better
not learning it the hard way and doing it right from the start.
Some learn by watching, some by reading, some just got to pee on the
electric fence for themselves ;)

Sometimes I'm a bit lazy on the clamp-down, and of course a clamped
piece can sometimes get loose.
Keeping the drill pushed down was good advice, but am I the only one
that keeps the belts somewhat loose so the belt just slips when this
happens?
Its easy to set the belt tight enough that it doesn't slip normally,
but only slips once the bit grabs. Then, since kinetic friction is
less than static friction, it easily keeps slipping until I can get
the drill shut off.
This is useful even when doing everything 'right' and the drill grabs.
Or maybe I'm the only one with a belt-drive drill press?
