Paul,
 I found a place called SCI Laboratory Specialties (
 http://www.scicominc.com/teflon_sheet_stock.htm) that has 3/8" x 12 x 24
 teflon sheet for $134.  Not a great price, but beats McMaster-Carr's price
 by $40.  Maybe I can sell two strips of it to some others on the list for
 their slide throttles.  Everything else needed I can buy locally.

The important feature of the McMaster Carr sheets is the finely finished
surface.
I don't see any reference to finish quality, and it is extremely important.
If they can match the finish for that price, I'll be happy to split one with
you.
