What kind of scopes do you build? Dobsonian?
I have something that resembles a Dobsonian on the boards right now — it's a miniaturized version of the 60" at Mt. Wilson, borrowing some of the innovations invented for the 200" at Palomar.
Basically: a "Dobsonian" (Serrurier-truss Newtonian) on a stubby equatorial wedge. It's about 3% done.
My workhorse is a rehabilitated Super Polaris C8.
