so can we use it or not?

I'm pretty sure thats the same piece. All you would need is a fitting to fit that onto the T instead of 3 reducers and a pipe and an end cap...that and it was like 4 bux i think at lowes, so thats gotta be way cheaper

And it being ...

I'm not sure. ill try to find one online... 1 sek

While getting the parts for my halo rocket launcher at lowes, my friend picked up a piece, because it looked funny. Only seconds later i realized its potential..i think. I snapped a pic, and ill describe what i think it can be used for to save lots of parts. Ive never seen one used before, but it is ...

Update: Central box is getting closer to done. I ran an ignition for one of the barrels, using a 15 spark gap(piece of a blank pcb) but for some reason it didn't work. so i had to redo it to just bare wires temporarily. also the cameras didn't work so i switched back to a bbq ignition. i fired the ...

I'm working on the middle box. its turning out to be a real P.I.T.A.. Ive tried 5 different materials, but cardboard is the only thing that i can cut with the tools i have and to the right shapes. i think I'm building the middle square box out of a box just cut in 3d out to that shape.its a real ...

heres a few more pix after a little more modification. I cut the wood inner lower receiver so you dont see it between tubes, and screwed it all together, so its all one, big, spud gun at this point. it still doesn't have propane injection or any ignition source(i have spark strips made, just not ...

Basic construction is complete! Details, paint,front grip,shoulder pads,and propane injection, as well as other small mods(chamber fan,spark strip,etc) are to come.

I do have one safety concern. I used all 3" fittings, and ground the little tabs(that are supposed to prevent you from doing this) off ...

UPDATE: Construction has begun. The chambers and barrels are in place, as well as both of the big tubes that house them. Glue is drying as we speak. Tomorrow I add lower receiver, 3 grips, ignition, possibly propane injection, and the big box

ill try to get some pix up tonight. its pretty sweet ...

So can i glue the ABS to the PVC barrel, or should i bring back the PVC and just get ABS barrels?

I just realized I'm using almost exclusively ABS, but i bought PVC barrels. I didn't even think to check if they glue to each other. I cant really find a definitive answer online, other than you can ...

hmmm. even tho i said i was earlier, i don't think I'm going to do coaxial. First reason being that that makes it much harder to do chamber mods,specifically a fan. second reason being I'm more concerned with how it looks, and THAT it shoots, not necessarily that it has optimum performance. also if ...

Well, just a little input, but if the two guns are the same size, you could make one propane meter for it, with a ball valve going to each gun.

Noname has the right idea with the propane system.
You might be able to set it up like this: See picture

The slanted lines in the middle indicate male ...

alright. when i get done with work(hour and a half) ill go pick up the cell core abs 4" outer barrel/chamber

im still not sure how to mount it inside. i heard 3 inch caps fit inside 4 inch pipes. does anyone know of any other peices that are easily modifyable to fit inside this 4 inch pipe?
What i ...

I'm going to add a small lcd screen and a tv receiver to the back of my spud gun so i can watch tv and spud!
