Joan, My 17 1\2" uses 4 1 inch pieces, 2 under each semicircle Teflon bearing. Works great!

With the hope that is sufficient in size for a someday 17.5" dob. I really don't know how much I need. Can anyone advise if I'm getting enough? ----- Original Message ----- From: kharrismar@earthlink.net To: "Brent Watson" <brentjwatson@yahoo.com>, "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Sent: Monday, January 19, 2015 3:42:32 PM Subject: Re: [Utah-astronomy] I need to get rid of some stuff Hi Brent, I'd give $10 for 4"x19" of the 1/8" piece.

There are a couple of pieces of virgin teflon someone here may be interested in. One is about 8 inches by 19 inches and is 1/4 inch thick. The second is about 19X44 and is 1/8 inch thick. I am looking for offers. Let me know what it is worth to you.
