Figured I needed a "Farm" pump for the kiddo if she emptied the HPA tanks from the booster and still wanted to shoot.

I started by machining an adapter that would replace the handle (attached using the factory metric screws that are counter bored below the washer) and accept a 3/8-24 studded rod end to attach to the crank (8.5" CL to motor shaft).
I removed the base and used a section of 1/4" plate (again counter bored for the factory screws) with a 7/16 rod end for the upper pivot.
Angle iron and box tube for the rest of the frame and added some ATV mounts I had to hold the rifles in place.
The he motor is an old eBay find, 3 ph 30 rpm max powered by a VFD from a 110v AC outlet.
