Very nice, higher spec than I imagined, that's not your average home depot garden sprinkler valve - and it looks like the traverse and elevation mechanism is quite sophisticated too. Do you tie it down for firing or is the trolley free to recoil?

The valve is a high flow gate valve rather expensive, The traverse is a simple center swivel mechanism machined from aluminum with a Delran bushing the ends ride on caster wheels to keep it from tipping sideways, its manually operated (for now), The elevation is made from parts of a train door operator system that we build at this company. It's a fast twist screw mechanism mounted to the frame and direct to the valve, there are pivot point at both mounting location to allow for the arc movement. It to is manually operated for now. the base is on caster wheels for ease of movement and we put a 40lb sand bag behind it when firing. This photo was taken before we installed the charging valve and the pressure proportioning valve.

I am wanting to go semi auto with this canon, so any ideas on how to make a loading port and a feed tube will be appreciated. We have a couple ideas but don't know if they've been tried before. Any input is welcome. Thanks
