Thanks for the additional photos, Stefan. They're most helpful, as
the time has come for me to build a rotating drill press. I see
you're using an inverted wood screw as a downward limit to motion. I
notice also that you have designed a simple fixture consisting of a
horizontal 3/4 inch (20mm)hole to hold the tool's fitting collar and
two horizontal woodscrews covered in rubber between which you wedge
the tool's opposing handgrips.
That's much simpler than the tool-holding fixture I first had in mind.
Very nice design.
Let me just ask you a couple of questions about your drill press:
(1) When you position the rotary tool's bit above the workpiece and
then let go of it, does the weight of the tool cause it to drop the
bit downwards, or does the spring cause the bit to move upwards, or is
it neutrally balanced? Does it matter?
(2) If you were to remake a drill press, is there anything that you
would do or make different?
