Re: wire rope drive

Hi Arnie,

I'm late to this discussion but I have built a cable drive system. A
few hints... If you put enough winds of wire around the driving axle
to accommodate the full travel in both directions and clamp the center
of the wire to the axle it is no longer a friction drive. (That is
good...) I used a 1/2" rod for the "drum" and 1/16" wire rope. It is
strong enough to ruin 1/4" router bits if you move the thing and the
bit is still in the work and the spindle is not running. Guess how I
know that!

HTH,
