So I figured out I just use 3/4" PVC for the thruster cones, but I still have no idea what the round parts are for. I will keep looking.
Anyways, here is an update from the weekend and this week so far:
Started cleaning up the pack, and as I said, got the connections in via PVC and elbows for the thrusters.
Also started received my Fetttronics and the Pulse 40 in the mail:
Also I got the knee darts and gauntlet darts in, and I began the mounting for those:
Added the Bantha skull to the shoulder bell:
Plus got a ton done on the gauntlets. I used the Wizard of Flight templates to get the back part of the right gauntlet. I actually just printed it on paper, cut it out, taped it up, then filled it with Great Stuff foam (the less expanding kind). The I just bonded it and mounted it to the gauntlet:
And here is what the gauntlets look like today:
And the left one:
Still have the left rocket to paint and install, and some leather work to do (not to mention the jet pack), but all in all I am pretty happy with the progress so far.
