I did something similar to this for my 120 lb Meade 12" so I could roll it into my garage. The idea was to keep the height low so I could clear the top of the door. I used steel U channel instead of Aluminum because I was concerned the aluminum angle would bend over time. Steel is stronger unless you go to a more exotic aluminum like T-7075. Steel is cheaper but will rust. The U channel was anodized so no rust so far. Also used 4" ball bearing castor wheels from Home depot and welded them to the U channel. I think the single bolt idea will not work well as a pivot. It will gall the aluinum and get loose ever time. Turning will be a problem as well. Ball bearings will take the load. This is still a good idea - I use this scope all the time just by rolling it out of the garage. No lifting!
