yea man :):) think it's worth a try?

very much likes jacks idea but simpler for me to make i think. i haven't made a pistion cannon yet. but i got the idea from a tank or anti airship gun how they load the cartridge into the barrel the closed the door on the barrel and fire. then remove it. it will be fun to make lol take a while and c...

i havent really been on here in a while so sorry if this has been thought of :) i've thought about ways of making a cartridge loaded cannon for a year or two now and come up with a few ideas that havent worked. most were way to expensive or two difficult to build. then i got to thinking what about p...

i'd go with braze welding. look better. will most likely be stronger. and if you can twist it free i wouldn't like to see what happens when you inject pressure.

damn. its to clean to say anything bad bout it. hows it shoot?
i need to pick my jaw back up.

gluing together a copper gun. think you shouldn't. might work but it would be better just to buy a propane torch and a few brazing rods and flux. plus if you braze it you can break it down using heat

i cant see anything to wrong with it. you might want to make a propane meter. you can wiki or search it. different ignition. say a bbq lighter or stun gun

wd-40 or similar, locktight make a product called freeze and release that works like a charm. we use it on everything encluding engines at work

multiple weld can do more damage then you think. just be careful. and get some one experienced to check

used at the rear to house the wires though would it hold. mine will use a burst disk

depends on how good a welder you are. if u have never been formally taught by a tradesman the no. btw i am a boiler maker so i do have a idea. mig welding is one of the easier welds to stuff.

no should. will take less time to fill thats all.

would cast epoxy be strong enough and seal well enough for it. thats pretty much the idea i had in my head. if you think it can seal well and not blow out for a 8 mix i will make a proto type cartridge.

cool idea but the problem still comes with the safe all steel construction. i'm stumped atm so i just need a few ides

i'm in aus. so thats a problem we can't make rockets.
also the gun would be steel for safety so i have to factor in problems caused by this
