Gas anyone ever Chronoed a mini?

If so what kind of velocities were you getting and with what ammo?

Does a regular bike with a weed whacker engine count?

Yes, that is sad. I go around and take lawn mowers and stuff people throw away, figure out what is wrong with them and then sell them.

It is a good way to learn about all of that kind of stuff, and it is also a good way to make money.

Use A 1/4" NPT tap, It will fit tight. I've never encountered a spark plug in my life that had 1/4" NPT threads. Not saying they don't exist, but you'd probably have a bit of trouble finding one. Most modern spark plugs have some oddball metric threads (or at least they're odd on this side of the p...

I Knew all of that, but I thought that I would only have the use one because it would ground through the gun or me. Uh, OK. Remind me to never fire one of your guns after you've upgraded to a stungun. :D You might put the piezo sparker on your tongue then click it. Just to get an idea of what a cou...

There were two electrical connections between the piezo sparker and the gap in the BBG. One of the connections may well have been the entire metal body of the BBQ. The sparker has two connections on it. You have to find them. The plug has two connections on it. One is the end where the spark plug w...

My current gun has a 8.something to one ratio, it is a 30" by 1 1/2" chamber with a 24" by 1/2" barrel because that all I had laying around.And it shoots very good. According to EVBEC I would need a 158" by 1/2" barrel to make 1.2 to 1, and it would almost double the velocity. I would need an 20 foo...

@Jimmy: In my honest opinion, if he doesn't know that by now, he really shouldn't be messing with anything more dangerous than a squirt gun. it came off of a grill and that wire wasn't even hooked up to anything, in fact when I started to bend the wire the whole thing came out, it was press fit and...

There is a wire from the end of the ignitor to the plug, and there is a small wire that runs down the side of the ignitor but bothe ends are hooked up internally.

I just built a combustion gun with a bbq ignitor and a automotive sparkplug, the problem is the the plug only fire if I hold the metal part of it.

I need to know how to fix this.

I just built a very similar gun, mine has a 1 1/2 x 2 foot Sch 40 Pvc chamber

and a 1/2 x 3 foot Sch 40 pvc barrel. I am using a ball valve to shoot it though. I am also going to put a 5 foot barrel on it soon.

I made a cannon with a 1/2" PVC barrel and it will shoot bottles about 60 feet at 30 psi.

Your an hour to the west of me.
