Hello

Could somebody show me links on the internet or refer me to books or
something that shows me how to build a dobsonian telescope?

For my 20" mirrored, 24" tubed telescope should I use altitude circles of
20" diameter or more?  Or maybe 25" diameter, 30" diameter (if it were 30"
in diameter that would be good because I already have some cut up that way
2-3/4" pieces glued and screwed).

Then what about the azimuth bearing?  What should I use for that?  A piece
of teflon; and where would I get some teflon?

Does anybody know where to get teflon?

Thank you.
David
