what is the deal that you stuck on the end of the barrel before loading it? and what do you use for fuel?

so if im not gonna get a fan, when i spray the fuel in the chamber, would it be best to wait a little bit after screwing on the cap for the fuel to settle in the chamber and not have too rich/not rich enough areas?

what does the fan do? air it out after each shot? id rather just save my money and blow it it after each shot if thats the case

in theory, with the right C:B ratio in mind, the larger the chamber the more distance you get correct?

thats too complicated for me at the moment. i just like the extremely simple design of the spray and prays. i guess ill just trash the big gun i dont want a 12 ft gun lying around i dont have any place for it. is there any way to get the peices apart? i glued them with pvc primer and pvc cement

you said you use propane, but you spray something out of an aerosol can in your vids... am i missing something here?

dam so i should really have a barrel thats 4 times as long as my chamber for it to shoot well? No, the barrel length to chamber length ratio depends on the diameters of the two pipes. With a 4"ID chamber and a 2"ID barrel the relative area is; 4*4/2*2=4 For a 1:1 chamber to barrel volume ratio, the...

ya thats what that huge thread says but i bought a can on saturday and it works fine...

dam so i should really have a barrel thats 4 times as long as my chamber for it to shoot well? thats gay i thought that if i just had a smaller barrel the energy would be compacted for a farther shot. i guess the pressure builds up throughout the barrel

yes its in the cap. and i moved the sparker into the cap on the first gun too, plugged the hole with a big hd screw i screw it on pretty tight everytime, usually have to use big vice grips to unscrew it, hope it doesn't fail though. i think the potato will fly out the barrel before the threads on th...

i have one gun that has 2 feet of 3 in pipe for combustion chamber and 4 ft of 1.5 in barrel. it shoots farther/better than my other gun that has 4 ft of 4in combustion chamber and 4 ft of 2 in barrel. is this just because i dont spray enough right guard? or will the second gun shoot better with a 1...

sports authority? easy enough

well i went to arei to see if they had one of those piezo lighter things and they didnt but i didnt see any extra flint either. would bass pro have them? thats where i got the lighers themselves.

built my first two guns this weekend. 1st was 2 ft of 3 in combustion chamber to 4 ft of 1.5 in barrel. 2nd was 4 ft of 4 in combustion chamber to 4 ft of 2 in barrel. unfortunately, i did not place the lantern lighter in the end cap on the first gun so every time i fueled it the right guard would b...
