Re: Threaded Rod/Cable Driven Encoders

Chris,

Not quite like that, but...

If you start with round stock for the nut; drill and tap it for the
screw, and turn a semicircular depression near one end (can be done
with a chainsaw sharpening file)

Then you stand it on end (depression end up), and saw partway down
(making 2 or 4 fingers with one or two sawcuts).

Finally put an o-ring in the depression you made earlier to provide
the force to push the fingers in... Use an "thicker" o-ring for more
force.

Works well. Will be better on acme than american std due to flank
angle.

Hope this helps.

P.S. the "other" end can be threaded like commercial nuts, or glued,
or clamped to the machine frame. If you have a lathe or drill press,
this is a quick and easy project...
