Some more of the pics from building the framework for the “working” quad gun out here in Seattle.
Trying for a little bevel on the the reducer and the 2″ PVC “slide” so it’s not as obvious its a separate piece
Making an end cap for the moving barrel
The barrel and end cap attached to the piston. The 1 1/2″ PVC barrel slides in the 2″ ABS pipe “slide” supported by the reducer with the “1” on it at the frame end, and the body of the gun at the business end
The PVC cement isn’t rated for the reciprocating action (found that out the hard way), so I threw a 10-24 bolt through the layers of PVC. Thinking of ways to make it better, but for now, the nut can turn on the piston shaft, so it works.
The over/ under pair with the slide showing on the lower, to give an idea of how the frame sits. Default is with the barrels extended
And after the lower barrel has “fired,” showing the 8″ travel distance
A different view
A co-worker of mine engraved this for me from a roofing nail. Thought it was a neat share.
Adding some support for the 6″ tube, as well as a location to attach a counterweight frame for behind the pivot.
The gun assembled and hooked up to air to show a friend who is now going to look at control for the solenoids for this thing. You can see in the foreground the second frame being assembled
The beginnings of the counterweight frame
The holes ill have 3/8″ bolts welded in through the frame to attach weights to.
the counterweight frame built. I later realized I am going to have to go back and fix where the stand-offs attach- the spacing is just a bit too tight vertically with the piston frames
This gives an idea of how it goes together. The counterwieght frame will bolt on, rather than be welded, an
The shot hammer is there because of the misaligned tabs and sleeves for the counterweight frame. Also give a bit of color, don’t you think?
The body on the frame. Notice how the 6″ tube doesn’t sag now that there’s a bit of support under it, compared to when it was hanging off the side of the lighting rack.
Welding the two frames in to one piece.
I had to pack everything up for when we loaded out of the theatre. I’ve already been appropriately chastised for it being piled like this. (head held low) Hey, at least I used a packing blanket.
Greg and I have been talking about figuring out the Rolls engine piece that forms IG-88’s head, and more importantly, the forward end of the main body of the gun, in order to replace the 6″:4″ – 4″:3″- 3″:2″ reducer sequence. Greg talked to a guy on theRPF who has a pep file of it. Printed out on 8 1/2 x 11″ card stock, the thing is HUGE. But that’s what scaling is for, right?
More to come
