HI- I am building a 12.5" full thickness mirror dob. I have most of the major construction done- am working on a spider- and secondary holder- and ran into another issue. What do you use for the "teflon" pads- on the bearing surfaces? A sheet of 12x12- 1/8" thick from amazon is like 40$. ---and I need like 1/4 that amount.
What can you use and what thickness do you recommend? I know I need two pads on the azimuth bearing surfaces, and like 3 of them on the ground board- all opposed by the (I forget name) black formica (stardust or something like that).
I have some 1" thick delrin- I could cut with band saw into thin strips-
Thank you for your help!!
