I had occasion the other day to contemplate milling a smallish flat bit of
metal to reduce its thickness a bit. it's L shaped and roughly 2" on a
side, and about 3mm thick.

Since holing it in the drill vice is obviously not going to work, and I
don't have a magnetic chuck (and in any case it's not ferrous), how do you
go about holding it on the machine so that it's flat, supported and stays
there to be milled?

Austin,

If it is flat you could try gluing it to another piece of metal which you
can hold in a vice.

Solder it to a base part or superglue it. Heat releases both methods.

I find plumber's soft solder very effective for this sort of thing and
easily removed by wiping with a damp cloth while hot. Just done this
while thining down some steel strip for replacement gib stribs for a
small lathe.

Superglue, Loctite 603 or Permabond A1046 onto a flat plate.

Light cuts

Release, either with heat (250deg C) or with a sharp hammer blow via a brass
drift (if the work will take it)
