From geonuc re:unfinished projects
Yes, from time to time. German design. We used 3/4" Boston pillow blocks for the bearings. The base plate holding the polar axis is 1" thick steel, quite rigid (have to love the scraps available in a big machine shop). Dad came up with what I thought was an ingenious idea for supporting it. He made a 2-piece frame out of 1/4" x 2" steel strips that would bolt to a 4" square steel pillar set in cement. The mount is held in the frame by setscrews in deep indents on each side of the polar block near the front and supported by another setscrew at the back from underneath. At the rear of the block two more setscrews in the frame can be turned to give a couple degrees fine tuning in azimuth and the setscrew on the bottom gives altitude adjustment. The frame had some spring but was incredibly rigid when tightened up.

I started with a 10"f6 dob. I think I would have been dissapointed with with anything much smaller. I got a book from the library and went from there, it was a great experience. Saturn was the first object my wife and I looked at once the scope was built and we were blown away. I found the night sky to be an awsome thing that I just could not get enough of. I started with a PVC tube and found it to be way too heavy, now it is aluminum. I would suggest using as many stainless steel and or brass fasteners as possible to prevent rust.
