When first tasked with creating a new mod I went to my cave and started digging in bins. I was quickly distracted by my stock Starscream Blaster, shoots darts, transforms, and most importantly, it's a jet.
The next night I decided to take full advantage of those features, but I decided to give it enough power to justify running around with it at a war.
Enter parts list:
1 Big salvo tank
1 Sm3000 pump
1 Tubing T
1 Hornet Blast button
1 45 degree CPVC coupler
3 .75 to .50 PVC reduction couplers
Tiny bit of CPVC
Some 1" and .50" PVC
Random lengths of random sizes of tubing
Materials for a breech, and enough .50" PVC to cover it (if not already used in the breech)
Start with this:
Quickly open it up before you get distracted, giving you this:
I got started before taking that picture.
I had problems with the orange caps, large amounts of glue and weak plastic worked against me here, and I could not get them off, to make later stages easier, and to get an overall cleaner look, try and get them off before opening. I ended up completely cutting them off with a knife later.
Gut the internals, and dremel away at the inside's until you roughly have this:
The top is a whole new ball game that I will get to later.
Cut down the stock trigger piece thing to this:
I though I had a picture of it stock, I thought wrong.
Next you are going to want to attach your internals so you can get a feel for where things are going (or do it before, whatever):
Now make your breech, there are many types to choose from, and I leave that part to you. The one I use I received in a trade, and as such I do not have picture of its construction. You don't even need to use a breech for this mod, but I feel it fit the look I was going for.
Attach the breech to the 45 degree coupler, and shove some CPVC in the other end. The length of the CPVC will depend on how deep you get the Salvo tank into the shell, for me it was .75". Dab some super glue on the CPVC and place it in/onto the Salvo tank, you should have some wiggle room. Work fast to get the barrel and tank situated before the glue dries.
Chop down some 1" PVC into 2 pieces .75" and 2 pieces 1" or so. Dremel out 2 of the reducers so there is no ridge on the end and cut one in half. Stick the 2 full length couplers into the 1" lengths of PVC, and the now 2 half couplers into the .75" lengths. Slide the .75" sections on the breech and pump tube respectively.
Use your glue of choice to secure everything in the shell now, I used hot glue.
Cut about .50" of .50" PVC and slide it onto the end of the pump shaft, stick the 1" PVC section with the unmodified coupler in it over this. The other section goes over your barrel, wrap both in packing tape until they fit snug in the orange caps, add glue if needed.
Now for the top half of the shell, cut a hole for your breech opening in the fake barrel and cut a hole to make clearance for the Salvo tank. Go slow to make sure the fit is tight as possible.
Once you have everything fitting how you like, reassemble and start practicing your jet noises.
2 cameras died in the making of this writeup, leading to blurry photos shot with a video camera.
I could have used 2 tanks, but then it would have left me no room for the pump. I also could have placed the Salvo tank completely in the fake barrel, there is room, but it would have left me with barrel sticking out, ruining the look I was going for.
Ranges when the sun comes back, and the wind goes away.
