Looking for a dovetail saddle which will accept #20 threaded rods

Posted By John MacDonough

Aluminum is pretty easy to work with.  You could just buy the dove tail you want and drill it yourself.  Regular steel bits for wood working will drill aluminum easily.

Hmpf!  Californians...  smile

Even though I didn't make this scope from scratch, I'll post this here.  I needed something to do during lock-down, so I decided to repaint a GSO 8" f/5 Newtonian I bought from a fellow Astromart member in February.  First, here's a stock photo of the stock scope.
