I gave blood this morning. All over my radial arm drill that I got a couple
months ago. The part snatched as the drill broke though. it rode up the
drill and then popped the vice grip holding clamp off and threw it. Then the
work made made a quick revolution before i could get out of the way.

I need to get a better way to hold work in the drill press. A couple vice
grips and pieces of tubing just aren't getting it. I've tried using a spare
Kurt type vise, but that is cumbersome. half the parts won't fit in and its
difficult to quickly line the work up under the drill and through an open
spot in the vise.

what's normally used to hold all sorts of odd ball one of parts in a large
drill? Just fabrication grade work here. I use a mill and bolt the part to
it for stuff needing accuracy.

For smaller work on drill presses those quick acting cam type vices work
well. They are typically heavy enough to be hand held and slid around
to align the work under the drill.

The above is a Wilton, the Enco brand looks the same and is somewhat
less expensive.

There is a similar vice I've seen (never used one) that has stacks of
swiveling plates instead of regular jaws to hold other than square work.
Enco doesn't appear to have one but I think I'd like to get one. The
one I saw isn't quick acting but has a screw.

To hold work that is too big or too scary clamp it to the table with T
bolts and something like these hold down clamps.

With a radial drill and work clamped directly to the table a good way to
pick up a center punch mark is to chuck a dead center or a rod ground to
a similar point and with the column and head loose and spindle running
(I was always taught to use reverse but I don't think it matters) set
the point in the punch mark then gently clamp the head and arm. You'll
be right over the punch mark.
