Ole BB's MOD to a Vixen 1.25" 4-SLOT SCT Turret:
I ditched the SCT ring. Then, I tapped & threaded 3 x 10-32 holes at ~ 120* intervals in the collar. Now, I can slide this collar over ANY of the Vixen 36mm to 1.25" adapters on my old scopes (after removing the thumbscrew), and lock it flush against it. And, I can loosen the thumbscrews, and position the eyepiece at the most comfortable angle... I couldn't do this by threading the Turret into the focuser flange...
It also cured another annoyance: That .965" Turret that fit directly INTO the focuser adapter would rotate when changing eyepieces -- unless I over-torqued that thumbscrew!
[I've definitely gotten my money's worth out of my Tap & Die Sets. Bought the first small one during the Mogey 3 restore, and the larger when I figured out I needed to replace some of the Tinsley's old corroded brass screws.]
