Hi from the quad v2 build again. I keep forgetting to post, but I've made a good chunck of progress, so here goes...
I started to skin the body back in early November. We had a good cold spell here in Seattle (yes, nothing like most of the rest of the US gets, but still) and I decided to bring the body into the apartment (after breaking a 10-24 tap off in the cold aluminum). When I set it on end I found the piston mounting bolts were still too long (had'nt paid much attention to them- they held the pistons in place and that was that), and needed to get shorter to start considering the ballast end of the gun


They needed to be inside the profile of the aluminum. Easy fix. Drive the nuts farther up the all thread, reset the jam nuts, and cut. Done
Then it was time to put the 6" PVC "blast chambers" in place

Add the reducers to the back ends

I'm considering changing the reducers to 6" couplers instead, it might look cleaner.
Adding the front reducers and the side wall frames, and...
or, with the plating taped on...
This was the sight walking in my door for the next day...
