pic: coupling for dual cylinder ballshifter

We can shoot ours by hand after we added a lever arm to a custom dog gear. Your design looks so refined and professional. If I didn't know better I'd have said it came from vex

Thank you so much. This is one of my favorite mods that we have ever done to a ball shifter

Since we can't 3D print, we ended up doing something a bit weirder / more foolish for our solution. We made a custom coupler that mimics the interface of the 10-32 rod and nut. Attached to the other end of this coupler is a female tapped hole for a 1.5" bore piston. That way we could use the off-the-shelf coupler but still throw more power into a system that probably needs it.

Were using quite a bit of force on ours. We had it working when using the high gear where it had to push the cylinder out of place but when we switched to using the low gear it didnt have the force to pull it free. our goal was to be able to pull it back enough to shoot from about 18 ft or so.


thank you for sharing the file. trying to find a way to get it printed out now is the next big challenge.
