I wanted a way to secure a mounting platform for a laptop, which I use to view approach plates. Using a RAM flexible mount, I decided to weld a 1/2 inch NC nut to the tube between the seats. A piece of 4130 was tapped to 3/8 inch NC on the inside and threaded to 1/2 inch NC on the outside in order to start the RAM mount above the seats, as there isn't much room between them.
