Looks good, my only suggestion would be to tap the fuel meter fitting and ignition electrodes through 2 layers of pipe next time, and maybe use a meter that has 2 ball valves, it would be easier to operate, and more accurate.

With a 1/2" to 3/4" bushing it holds in fine, and when it is cold outside I would need multiple shots of Mapp gas because the PSI drops low in the tank, 1 valve works fine for me.

The steel pipe is of considerably more volume than the hose per any given length, simply extending the pipe a few inches (you can certainly afford to with that long chamber) and using 2 ball valves would increase the meter volume to substantially more than it is now.

Nice gun, very well thought-out, very clean construction. Looks a lot like my over/under metered propane gun.

How do you hold it? Are you going to add handles?

Peace,
Pete Zaria.

I hold the front on the barrel, then my other hand by the rear where the elblows are. I'm not entirely sure if im gonna make a handle, I might tho.

Do you have a link of your gun? I would like to see it.

I'll try to post some better pics sometime soon.

Note, I used zip ties instead of hose clamps - either seem to work fine. I might change to hose clamps when I paint it. I'm going to paint it glossy black - but I'm waiting for it to warm up outside. I'm also going to add a stungun circuit. The BBQ sparker jumps all the gaps on the spark strip and it's never misfired yet, but I want to say I have a 100,000 volt ignition. So stun gun it is.

Peace,
Pete Zaria.

Wow, your gun is insane! Very nice job, it would look awesome with black paint. I would suggest you change to hose clamps, they look better and you dont need to cut (and throw away) when you need to take them off.

Right now im finishing off breech loading for this gun, I will post pics ASAP.
