When Grainger's and McMaster-Carr fail to have THE items you need...you make them. 15-tooth, 4.66 module gears have true involute profiles for smooth power transition and quieter operation, longer service life. I went with the largest feasible gear teeth, because they will be stopping the barrels dead from as much as 900RPM, repeatedly. All tubing is JM Eagle ABS cellular core ABS and 600psi rated PVC. Weight is about ten pounds, Size is 24 inches long, ten inches tall, nine inches wide. Barrel pack is eighteen inches overall. The side-mounted pod that looks like the minigun's motor is empty, and has a removable rear cover. This pod can also be removed from the main chassis intact. Wing nuts are used to hold the main body assembly on the minigun together. All painted ones shown have since been replaced with fresh plated hardware. This particular example of the Killbucket CoffinLoader is a bit rough. It served as the prototype for making the initial parts for many different variations of the basic minigun assembly. On this one, the rails are thick aluminum tubing. I really dislike the wing-nutted joints at the front handle. Lots of extra effort to form the ends, and they have to be "clocked" properly to line up. The single version CoffinLoader has a pair of parallel tubes like on the dual models recently posted. Also, the barrel guard loop isn't as far forward as you see on this one, and the drive motor is fully exposed. I am Killbucket, and I have made over 60 motorized <b>...</b>
