Thanks! The Tinsley Project feels like it's on either Repeat or Shuffle since I first got the OTA. Getting the EQ mount from Dave Trott was the watershed moment for me. It's driving this 2nd restoration. I want the scope & mount to at least coordinate color-wise -- the styles already do.
Once the DEC axis gearing is done, I start what I plan as the last OTA restore -- at least by Ol' BB. The secondary cell was missing. I made a quick & dirty one for mirror testing; then, the better quality version in it now. But what I want is an all-brass final version, and for that I'll have to go to my local machinists -- and if they take it on, it'll be on their schedule. "A brass can with an 8 inch brass rod" is how I'll describe it to them. They built the complicated shock-resistant lens cell for my Jaegers 4" F5 refractor, having never done any work like that before, and I know they can build to precision.
I went crazy polishing the brass on my 3" Mogey, and learned some lessons for the Tinsley: Now I only remove black tarnish, with the idea of having it look Old & Used -- but not abused.
JD, my powder-coat guy, has done 4 vintage scope tubes for me -- brass, aluminum, & steel -- and he does great work. I've already talked to him about 2 different medium-gray high gloss colors for the Tinsley that'll make all the brass hardware really stand out. All I gotta do is get the optics & cells safely removed -- no spare parts with this scope! -- and pick one.
It's a shame that the mount & pedestal are just too massive to keep indoors. Talk about a grand old scope! She really should be on display. Can't tell y'all the number of times I've had to explain to family & friends that the Tinsley is most certainly a telescope. It doesn't look like any of refractors, which are Real Telescopes to them.
