Hello!
I have an 8" Dobsonian whose bearings are decidedly
unsmooth, and have been looking up suitable ways of improving this. Most sources seem to suggest Teflon + Ebony star, only it seems like ES has gone out of fashion... another suggestion I've heard is fibreglass reinforced plastic (FRP), although I have no idea whereabouts I might find this?
Does anyone have any suggestions for smooth dob bearing materials, and where I might be able to pick some up the small amount required? I live in Brisbane.
Cheers
