(ATMoB:Discuss) Question about Teflon



OK, I'm slowly getting sucked into this ATM thing... Time for a stupid
question:  I'd like to build a simple Alt/Az mount for a little 90mm F/11
refractor I bought during the Natural Wonders death throes.  I've got a
basic plan, but I need some pieces of Teflon to smooth the motion in a
couple of places.  I know you Dob builders do this.  The question is -- what
do I look for in the hardware store?  I was in Home Depot the other day and
my description was only good enough to get very odd looks from the people
there.  Thanks for any clarifications.
