I would like to construct tube rings for a 4" Dynascope that I can then attach to a dovetail mount for my goto. The actual diameter of the tube is slightly less than 4." I know that I can buy something that might fit this, but I was wondering if something simpler (and more economical) could be substituted.
Thanks for any information you can offer.
