Turret rotate is a very basic setup. A 3/4" hollow shaft passes through two bearings that are inlaid into the deck. The top part of the shaft is welded to a simple brace that is bolted to the turret base. A simple 12 volt motor powers the nylon gears. Servo wires for the elevate and gun trigger pass through the shaft. Inside of the black box is a scorpion mini speed control. Works nice and smooth , no binding in either direction.

I just love how Those bottle clamps work. Thanks to Bill, Pz 38t. I saw them in his pics, asked him what they were, then found them at Mc Master Carr of course. Perfect fit , and that bottle is not going anywhere on its own. Also visible is the new bracing for the feed tube. There is a lip on the right side and a small screw on the left to keep it in place.

Operational. Red button on the right is a fire button to test the system without using the transmitter. Box on the right is the firing circuit for the marker. Thanks again to Frank for assembling the electronics. And the last piece installed today, servo city mount as the elevate. Later I will install a balance system for the gun, but it will suffice for the battle on Saturday.
Well, this would have been battlefield testing last Saturday if not for the freak snowstorm.

Latest update : Added rubber to the plastic wheels. It gives me the exact wheel size as originally planned. Also, reduces the plastic clacking noise. Much quieter now. Just used 1/4" by 3/4" rubber tiedown straps. Plus a generous helping of a 3M contact adhesive designed for these materials. Plus a few recessed brads , you know, extra engineering overkill never hurts. Performed great at our 2 day event.
