this is my hybrid so far, i still have a ways to go. I just wanted you guys to look it over to make sure all of the parts look ok. I need to add the propane tank, pressure gauge and spark plug. any comments are appreciated.
thanks

Those galvanized pipes look snazy. Good luck!

Looks good but some specs would be nice.

Yup looks good, but we cant read the small text thats on the pic.

looks good!
but you can run the propane meter along the side with an elbow to make it more (compact)
other that that it is good and go on to the 6x mix

you can use a bigger union and a shorter nipple to secure it...

I'll post specs when it is finished. Working on the spark plug right now. how do you guys attach propane tanks. i can get them for $2.50 but they don't have any attachment on top, just the threads. what fits on those? thanks

you can get the propane adaptor from bcarms

or you get one of the berzomatic flame torchs and thread it like on burnt latke.

Or you can use crowlys ingenious simple method

very nice design.

small, compact, and neat. job well done mate!

just one thing....
promise us you won't take it to school. lol

it might be in the diagram, but i cant tell. so quick question, what are u ignighting it with

I got a electric bbq lighter and a propane tank today. I have to get a new pressure gauge because mine won't attach, and a hose for the propane. After i took off the little attachment on the end there doesn't appear to be a hole in the tip of the other piece with the valve on it. is it just really small or is it not there?

The hole is there, but it is tiny. I cut my torch head, which eliminated the pinhole. I rally can't tell a difference in the filling process, though. I just cut it to get it straight.

BTW: The hybrid design looks pretty good. Mine looks quite similar, although I use an elbow for the meter to put it closer to the launcher.

And here's some more advice (assuming you have not tested it yet). I used JB Weld to seal most of my threads to keep it from leaking, but I can't take it back apart (don't really want to). As far as the union goes, there should be a brass ring in it. If you take it out (mine came out when I fired it) the groove left will hold an oring, to keep it from leaking out of the union.

Just FYI, you generally use teflon tape/paste and tighten it with a pipe wrench.

And pat, you can completely remove the curved pipe from the blowtorch. It attaches at the bottom near the knob with 1/4" compression fitting threads, and can be easily removed with two wrenches. That should solve any connection problem you have.

Yeah, I know. But I didn't plan on taking it apart and figured the JB Weld would make for a better seal. I did use tape on the meter and sparkplug, just not on the chamber.

If I knew that I would of bought the $2.50 propane tank with no connections instead of the 19.99 one.

edit: I can just connect the propane tank with a hose right. just slide one end over tip of the propane adapter and the other on the hose fitting. what size hose should i get? I finished the spark plug. it looks pretty good.
