Re: Back to the rack - nuts to the nuts

than .003 inch. This may not be attainable with cheap rack and
Browning doesn't even want to discuss the subject as their product is
not intended for this purpose. I haven't priced precision ground
rack and pinion yet.

Doug,
Look at the gates belt catalog. They sell a linear cog belt that is
meant to be stretched along a surface and used as a rack with a
matching pully. I looked a while back, cost was good, accuracy was
good and strenght was amazing. Should be no backlash with zero
thermal affects.
