lol, this hybrid was originally going to be a 30lb. rifle with on board mapp gas/ oxygen injection system with a 500k stungun mounted on the side until my cousin told me that i was going to amputate my arm and possibly blow my head off. (actually he just said it wasn't smart)

it would have been ...

yea theres videos somewhere. Think they're on the old spudtech forums. This thread seems to get bumped on a monthly basis. I don't plan to make any changes to this thing. "Hi" is it even still down there?

hahahaha I thought that looked familiar. Jesus, your at almost 1k posts. Looks nice cuz. Hopefully we'll come down sometime in the next month or so.

Well if you buy one of those really cheap ass torch heads, the tube part will screw off (its lock-tited on, so use some heat and muscle to get it off). When you get it off, it will be 1/4" compression fitting threads on one end, and the propane on the other. From their you can buy a comp to NPT ...

Honestly, can some admin lock this thread? This cannon is currently in a pile of parts anyhow, and all the recent posts in this thread have been useless crap.

or they're like a buck or two off of Mcmaster.com

well its nice to know people still think this is a nice launcher

the rubber cap on the piston bubbled out and jammed on the second test firing...So that needs to be replaced, but I'm feeling lazy,

Mcmaster has em

barrel sealing valve

Well glad to hear I inspired you, I look foreward to your new valve. Ill post a video once mine is working properly.

I did test it, it holds air, but I am in the process of modifying the exhaust system (the 1/8" opening wasnt enough.) I also had to rebuild the piston, there were structural problems, but that is fixed now. Not giving up on it, its close.

Is that little bitty brass box your exhaust valve? Unless you have o-rings on the piston or that box has a surprising amount of flow, I wouldn't think it would be able to fire the valve.

In some ways it does have an o-ring. There is a complete rubber ring around it that doubles as the sealing ...

1)yes
2)holding the front end on
3)the front end is sealed with some silicon compound, like the stuff used in sealing showers (its adhesive, but removable)

Thanks for the complement, its always nice to hear praise. Hopefully it'll work

I will know tomorrow, I'm assuming yes. The rubber is about as soft as inner tubes.
