One more straightening technique. Get a couple of pieces of hard wood
(maple or oak) about 1.5 x 1 x 3/8. Sand or file a "sinusoidal" notch
in one piece about 1/16 deep and 3/8 long overall, all the way across
the 1 inch width. Any smoothly transitioning divot should be OK; just
don't make it too abrupt. Then make the other piece with a bump on it
to fit into the first piece. When put together, there should be no
big gap anywhere.
Hold a 5 to 6 inch piece of MW in a drill chuck (drill press is best)
and run at the lowest speed. Squeeze the wire between the two blocks,
forcing a bulge in the wire. You may need to use a pair of pliers to
get enought force. Pull away from the drill chuck slowly and the wire
will straighten. Don't try longer pieces, because when the blocks are
leave the wire at the end, centrifugal force will make the wire bend
out. Cut off any bent ends and the rest of the wire should roll
between your fingers without any runout.
I have made a tiny version with a bump about .015 high and 5/32 long
for straightening down to .005 MW.
