Well after getting put aside for a bit to work on my armor I decided to start this project up again and thought it belonged here so I can leave my other thread as a armor WIP.
I started with a high torque model airplane starter motor mounted to a piece of aluminum channel. I then dug deep in the bits boxes and came up with a hard compound bot wheel, a stainless steel rod for the barrel pivot, and some PVC pipe for the barrels. After some research I decided to try my hand at a semi game spec model (ie Not much chance of me following someone elses design to the letter) the ingame version would be hella long and impossible to handle whilst troopin around in full armour so I opted for a infantry variant. I started with the barrels by cutting 3 sections the same length and gluing on some threaded adapters. Then I cut 3 plates from 1/4" ridgid PVC for the barrels 1 in a rounded triangle for the front barrel guide and 2 circles for the barrel supports and drive wheel. After tapping the circles to accept the threaded adapters and drilling the triangle to slip over the barrels I then coated the barrels with a small amount of filler right at the base. The filler allowed me to machine (LOL hitech) in the barrel taper you see in most weapon systems of this nature.
I then drilled a hole in the center of each plate to accept a bushing that rides on the stainless shaft and allows the barrel to rotate freely. After measuring the shaft and barrel setup I machined a grove in the stainless shaft to accept a E clip to keep the barrels from slipping off and welded a mounting bracket to the other end of the shaft. Next I drilled the bot wheel axle out a size smaller than the barrel plate bushing and heat seated the bushing in the wheel and barrel plate. A quick and dirty test run later and I was off for more parts and a long break to build my recon gear.

Now for the update I found a quick crete concrete casting tube that was the perfect diamiter for a body and formed a fiberglass endcap for it, then I bent a section of aluminum plate for a trigger mount which will be built up with foam and fiberglass later in the detail phase. I scrounged up a very old flight sim control stick and gutted it to mount a momentary pushbutton switch then filled all the extra holes with a epoxy stick and gave it a coat of plastidip spray. I have piles of NMHD batterys from my RC trucks so I plan on running one mounted permanently in the case with a external charging port mounted on the side it will cut down on having to dissasymble it everytime I need to charge the cells. I wired up the momentary switch to a military style lighted toggel as a main power and safety switch. I dont want anyone accidentally hitting the trigger whith someones hand in the barrels this is a friction drive so there is slippge but it will break fingers if you grab it at full spin. I also still need to come up with a realistic carry handle and build my flack shield out of lexan then mount my barrel leds that I hope will work at this rate of fire.
So with all that said and everyone caught up heres where I stand sorry for the lack of action LOL.
