.68 cal works out be around 11/16ths of inch I believe , I cant find any of that super heavy schedule pipe anywhere near where I live. I want a piece so that I can make a horizontal loader for my tippy 98C. For a loading tube 3/4 inch will work fine but for a barrel it is a bit sloppy unless you can...

no, Im pretty sure pyromaniacs have a bad name because there is NO good reason to run around lighting stuff on fire for the hell of it.

well if multiple sparks dont make a difference, why do they work so well in automotive engines? I realise that the fuel/air mix is compressed in an engine but that just makes it easier to burn in the first place. If they made little difference people wouldnt buy or use them, and manufacturers wouldn...

LOL, Slacker!!! 15 minutes, bah, what are you getting old and slow?
If it was one thing that I was correct with- it was that you would be sure to post some numbers. im putting you in for a raise.

That is another reason to use a fan in the chamber to mix the fuel, it will provide a much more efficient burn. With a higher voltage ignition source, you will be able to achieve not only more sparks but also bigger sparks- which will begin burning the fuel at many more spots at once, effectively cr...

Im thinking your estimate is roughly 896 high! ( if he didnt type his figure wrong) and not to be rude but I think you misunderstood the question. He wants to know how many shots can be made with the air provided by a CO2 tank that was meant for paintball guns. This question I cannot answer personal...

^UMMMM, OK. Im thinking that there might be a design flaw here^ I just built a mini last night, I brought it to work and 3 people have asked me to make them one, might be cool little xmas ( holiday- for the politically sensitive) gifts. Im trying to get one of the guys to come on the forums, he's al...

The best part is : " He beat US up....." LMAO! isnt there some unwritten rule that there is safety in numbers? and why would the guy thump ya if there was a witness? All my neighbors all around me get a kick out of spudgun, they like to watch and they even take turns firing it. the 5 0 havent been c...

My big combustion is running a C:B of 4.5:1- 4"diam chamber and 1.5" diam barrel and im landing them 600 feet out with 4.2%volume. not super distance but fun and loud just the same.

sweet lookin tater totter! I couldnt be left out of the fun, so I went and built my own. ghetto job, but what do you want for 5 minutes of effort? I was firing Q-tips and chunks of apples and little balls of modeling clay at a plastic cup. I even let my 6 year old daughter try it out (only after a s...

Sorry for the delay in replying, but that thing is AWESOME!! It looks great on that stand, and it fires like a champ. see, now look what youve done, i gotta make one for me now. I wonder if you could use pieces of french fries for ammo, seeing as it IS a mini SpudGun! That thing would be a riot on t...

I was only going on what the original description said( for the capacity ). Really cool idea though, I like it. Im sure your plan will function better than a real M249, the SAW (minimi in France) is a real turd of a gun. Gimme a 60 anyday, the hog is a much more dependable gun. but back on topic: Th...

A few people here have fired them, youll find them if you search for it. 3/4" PVC is some pretty floppy stuff so you might want to find a way to stiffen it up for accuracey. either sleeve it with some tight fitting pipe or slide some reducers ( 1" x 3/4") over the ends facing each other then put a 1...

12mm (12.7mm) is 1/2 inch, try "AA" batteries. Havent tried it yet but isnt that also known as .50 caliber? maybe some muzzleloader slugs. But um no more of this shooting at animated (living) targets,ok? try to find some 45cal rounds that are saboted up to 50 cal, they will be lighter and fly with m...

buttpipe :evil: LOL, wtf? dont hold back, tell us how you really feel. then promptly pull your head out of your......buttpipe. why do you people insist on posting useless things like that? At least TRY to make an intelligent comment ( although the odds are that you will fail horribly in the process...
