I finally got off my butt and completed my air op conversion on my machine. Mounted a shortened 2 stage air cylinder without drilling a single hole in the machine. Manufactured supports with 2 diagonal having support blocks above and below z axis. Brackets below z axis prevent any possibility of support spread. All steel parts TIG welded. Control valve is mounted to small steel plate bolted to trailer light magnet. It's massive overkill on support but leaves easy accessibility to everything.
