Hello
Just thought you might be interested in the Acme threaded rods that Enco has
in their latest flyer. Looks like they might be just the ticket for those who
want to do CNC routers. A six foot long 3/4"-6 screw is only $12.69 and the
nuts are $1.99 each.

Enco's web site is at www.use-enco.com/

The sizes range from 1/2-10 up to 1 1/2-4. They sell them in 3' and 6' pieces.
Just an FYI from the middle of the desert!

Have fun!
