g'day kids,

i was around at barge's place today and we had to chuck out his old hot water service, so naturally we pulled the ignitor off it and went to bunnings to get a length of 90mm PVC pipe and an end cap.

we drilled a hole into the end cap and screwed in the ignitor, then put a lemon inside it, sprayed in the flamable gas and hit the ignitor... NOTHING!

after much frustration and confusion, we went to the kitchen to get his gas stove lighter thing (don't know the technical name for it) and drilled another hole in the end cap.

we sprayed the gas in the pipe again, lit the lighter, and nothing... until after about 5 minutes when it made one of the biggest bangs i've ever heard, but still didn't shoot the lemon out!

can somebody please give me some insight as to what we're doing wrong! it's giving me the heebie jeebies!

thank you!
Mat :)

:lol: :roll: Man your NOOBs :p

You need a Combustion chamber on the end using a larger pipe/container with a end cap with a step down(one unit like a "T" joiner) into a 90mm pipe(or something that a ORANGE/potatoes [or something else] not lemons can fit into)

So the ignitor is in the larger chamber and the orange fits snugly in against the end of the step down.

The gas will fill the chamber and when the gas ignites the pressure is tight against the object and it will be forced out under pressure.

We shot an unripe orange over 300m over a toilet block :lol:

Good fun.

I wish i had pics to show you.

*Edit* This of course is Illegal guys :lol: Oh and be careful

Link Have a look at that pic.

Awesome way to blow your arm up mate. Sorry, but i'm sick of treating people for stupid accidents. If you don't know how to do it properly, don't build it. Have fun driving your AUTO evo with one hand!!!
 
it was barge's idea anyway! :lol:

something had to ease our frustration from the cars... i think we might give it another go this weekend, with the reducer on the pipe instead of the equal diameter pipe that we have at the moment.
 
hehehe just saw this thread.
I useto make them out of steel (no compression chamber) and used Black Power as the source of the bang :wink:
What ever we stuck in them, was never to be seen again :| (neither was any Cat/Doq for about 3clicks) :oops:
 
lol

ive made one of these before :D

some pvc, some green pipe glue, a ignitor.

Looked like this sort of :)

These things work alright, but only with potato's. Lemons just shread into bits. Put the potato at the end of the pipe (not in the chamber), spray some hair spray into the chamber, quickly close the lid, and flick the ignitor at the back.

I dont know where it is these days... hrm.
 
I personally prefer kittens.





















jk :lol:

i'm very ANTI animal cruelty, it's fucking sickening to my stomach.
 
my bad :lol:

something that is also good fun is putting glad wrap over the end, rather than putting an orange in it.. using the normal method, then launching it

gets about a one and a half metre flame :D
