Yeah I did make the trunnion caps and wheels, the trunnion caps took a couple of tries before I got what I wanted with heat and bar matching the trunnions dimensions on the gun, the wheels were probably the easiest as well as fun making compared to the rest of the carriage. The axles are wood also with steel sleeves, the steel on the wheels were a bit tough tho, I formed the steel around the wheel and cut them short to create a .060 gap and wire fed them closed which caused them to shrink and stay on ( I guess it's a modern way to install tires on the wooden wheels). The whole project took over 2 1/2 months to complete.
