MOCKED UP with a shorter-than-will-be-fitted barrel cluster. http://www.air-sharp.com
Another days' smoothing, and it's time for minigun paint. I dropped the chroma from this series of pics to get a better idea how the outlines were coming. It's a dead match to the CAD; very little variation from concept to reality. The carry yoke is just about completed. I went one more filling step after this, to fill in the low spots in the corner gussets.
I added the little tab to hold up the tail on the carry yoke- the bit under the joystick handle that isn't there in this pic.
Parts to make the electrical box on top of the DC motor. There are a few more parts needed to complete the minigun's electric box, so it's just sitting here for the shot.
Angle of the upright portion of the aluminum minigun yoke: 15 degrees, not 14, not 15.5.
After a bit of filing, the wing-knobs are ready to rock. A simple captured bolt design: reliable and rugged. I have a bin full of smaller ones. There were looking better in my head, so I made up a set. The wing-knobs screw into threaded bosses in the crossbar.
Next, put the wing-knobs together, fill in the holes in the delinker, add the deflector to same, add a bit more body detailing.
I will also be making up a chute adapter part to clip onto the delinker, I think. I don't have a chute devised (not one that can be economically produced, that is) for these, but it will facilitate hooking SOMETHING to it for filming. The trigger will enable the firing circuit only, and it will be a DeadMan trigger at that: this gun will have a heavy-duty cable harness with another trigger button for the director or foley to control the gun's operation. The speed control will be built so that the rotation speed can be locked at any set RPM by turning a screw in. Thus way, any visual effects from rotation vs shutter speed can be tuned in/out as desired.
I've been looking at the GAU-19 again this morning. Funny how the assembled shapes do get simpler the more that I study them. The GAU may be THE choice for a "That cannot possibly be real" oversized gun for the Killbucket Truck.
I am also going to be making a VERY realistic AMMO CHUTE for this project.
But first, off to Mr. Dentist to get impressions done. :(
Fun stuff: Killbucket is getting BIG Upper FANGS. Really. 2 weeks from today they get installed.
I can't wait to scare the crap outta my dogs.
