Some 9 o’clock net regulars wanted a picture posted on the PSRG repeater blog. Here it is:
It’s  made from a 1/4” square nut brazed to the interior of a smaller (but  still pretty large, about 1.5” outside diameter, inside diameter  circumscribes the nut) washer, in turn that’s brazed to a really large  washer (large enough that its outer diameter just about matches the  diameter of the magnet on the mag mount).
The  1/4” thread mates with a standard tripod head. Tripod is an old beat-up  one I found for $1 at the Rotary Auction and Rummage Sale last month.
