something that may interest you, if you've been thinking of making one
of those little co-axial indicators shown at pages 83-91 in TMBR#3.
One of my customers made a run of the rockers (see page
for this project for me on a CNC wire EDM machine. They are made
from O-1 ground flat stock. They come
with the two holes drilled. They are unhardened.
The surface looks a little rough in the
above pictures, but that is more a
lighting effect than a rough surface. A brief rub on 400 grit
paper would have this part looking and feeling very nice. You'll need
to go over the edges with a fine abrasive stone to ease
the sharp edges, and you might want to harden the part, but I don't
think that's necessary, because it doesn't see a lot of wear.
Price: US $24, including postage.
