Two basic combustions

[homedepotpro]

the bottom one has a 3'' chamber and a 2'' barrel it is about 3.5' long, made of abs. i get about 120 yards with a spud


the top has a 6'' chamber and a 3'' barrel, the barrel is abs and the chamber is pvc, i know doesn't sound safe but its only hair spray, im not going to put a propane injection system on it. anyways, this one is LOUD, makes my ears ring. the pump is used for venting.

hers some more pics

Wow, those are really interesting looking, especially the gold one! I am not sure how safe they are, with PVC bonded to ABS...

[homedepotpro]

the black one is perfectly safe but the gold one make me a little scared

[hi]

cool, that thing looks so cool. the smaller one is ehhh, ok, but the big one is (sic). very nice.

the big one is very cool, I'll trust you on the connection, it looks very cool and fun. I surprised you could get 6" pvc but not 3"pvc
only thing I don't like is the cheap stick lighter ignition, but the handle is good

and the smaller one is nice, but the handle looks backward

the ignition on the big one is actually from a propane lantern and it is pretty struddy. i know the handle looks backwards on the smaller one but i like the way it feels and it makes it easier to push the button with my thumb

[hi]

what did you use to go from 6'' to 3'' on the big one? it looks like you made a plug and vut out a big hole, but what is it made of?

[homedepotpro]

its 1'' laminated mdf that is glue and bolted into place
