Hi,
I'm in the process of making a dobsonian mount for my 4.5" scope the plans for which I've made using the San Fran Sidewalk Astronomers website as a reference. I've virtually all of the mount made from 15mm MDF but need one more thing....Teflon.
How easy/difficult is it to get pieces of teflon???
If it is difficult, is there another material I could use in it's place?
Thanks,
Michael
