Is there a gadget out there that would de-burr / put a 45 deg
chamfer on the end of a range of small diameter rods (say 2-10mm
dia)?

I have a grinding wheel with a drill
sharpening attachment. It is just a
short length of angle iron that holds
the end of the drill at a fixed angle
to the side of the grinding wheel.
It also chamfers the cut ends of rods
quite nicely.

When the rods are too short to hold I
stick them in the electric drill and
spin them against a spinning grinding
wheel (usually for putting points on).
Rough cuts when the spins are in the
opposite directions, face the other
way for finishing cuts.
