The pile of flat stock was waterjet cut by Westar Mfg.
out of 6061 aluminum and 4130 steel.
Drawings for this collection of parts along with materials, thicknesses and quantities can be found here.
The top armor and two supplimental weapons were not included in that collection to allow modifications to be made for weight purposes. Those files are located here.
These drawings were done with the intent that most would be made on a waterjet, and as such did not require dimensioning. Each of the drawings that was meant for waterjet cutting has a 1" reference square on the sheet.
With the great deal of interlocking components, the order of assembly is important. The first components to be assembled are the weapon hub, support hubs and weapon sprocket. Doing this first also showed the first issue in the build. The sprocket model on McMaster.com did not have the correct hole spacing which meant only 3 of the 6 planned bolts would fit. These holes are all meant for a #10 bolt, and without a clearance hole bit on hand, one had to be ordered.
The other main piece of the day was countersinking the holes on the inner rails to ensure there would be no contact between the moving roller chain and the bolt heads. The front threaded spacers also needed to be added and loctited as the bolt heads will be covered by the D shaped bearing blocks during assembly. A product called Nutstrip
is used to connect the panels together, allowing for quick assembly.
