My new propane cumbustion luncher

[David603]

Taking in mind that this is my fist spud gun, i am quite pleased of the final result. I don't think there will be an other one very soon though ($$$) but i think i may refine it and maybe try to do a faster reloading system. Any ideas?

Nice job! Not sure what kind of "grinding, cutting and tapping" you did on your propane bottle adapter...all you should have to do is unscrew the crooked torch pipe out of the valve adapter housing. It's locked in pretty good with an epoxy of some sort but it can be broken loose with some big pipe wrenches or a pipe wrench and a vise and some he-man effort.

Once the torch pipe has been unscrewed, you can screw a 1/4" compression (tube) brass fitting in there...usually a 1/4" tube to 1/4" NPT brass adapter will do the trick.

Well the thing I did was that instead of unscrewing the nozzle of the torch, I just cut it with a grinder, used the same grinder to take off a bit of the wall material and then I used a tap to thread the tip (1/8 NPT)





And this was the final result...

Hey.. You shouldn't be posting on old threads.. Just private message him, and ask him what he did.. I saw your other thread too.. You should really show us what experience you've had with cannons before attempting to build one of these.. They are a LOT more complicated than they look.. (Sometimes, that is.. haha) Again.. Just private message someone like me for answers, but preferably a moderator.. Happy shooting!!
