|21" Alt Bearings for John T's 13.1" F4.5 telescope.|
Continuing the "head start" on John T's 13.1" telescope, here's the alt bearings and rocker box sides for his F4.5 telescope. I need to add the "lip" to the alt bearings. Otherwise, they're complete. These alt bearings are 21" in diameter.
You can see that the alt bearings and rocker box sides are part of the same panel of Baltic birch.
