well.. a sparkstip is the reason i asked the first question 
... how to get the whires inside the metall chamber, and still make it airtight. i want to build the cannon so i can convert it to a hybrid on a later stage when i get the balls for it
edit: im from kristiansand

Threaded hole in the chamber, delrin threaded plug through it, through which the wire goes through. Seal with epoxy, voila

Not really, composite materials which heavily feature epoxy resins are on the cutting edge of technology.natas wrote:epoxy..... ghettos best friend
Do you really want to argue with a man with such large sideburns

På min hybrid brukte jeg en 3/4" blendeplugg i messing med en sveise tilsett pinne for TIG sveising med en krympestrømpe på, denne isolerte bra nok til at jeg kunne bruke høy spenning på systemet uten overslag.
Boret ett hull i blendepluggen en halv millimeter større enn "stål pinnen" og krympet strømpen på pinnen der hvor det ellers hadde kortsluttet og fyllte hele innsiden av blendepluggen med kjemisk stål (form for epoxy) og bøyde deretter pinnen slik at den nesten berørte messing pluggen på innsiden, da fikk jeg en pålitelig tennplugg.
Denne burde kunne brukes til og lage en enkel gnist stripe.
Da jeg ikke er noe særlig flink til og forklare slike ting med ord må du bare si ifra om du vill ha det tegnet, kan også tegne en enkel skisse av en gnist stripe basert på denne pluggen.

Metering system done
1/4 brass couplings soldered with silver to a 316 pipe and polished, its easy to adjust length if the size is too big.
Volume of the pipe with couplings is 0.36 litres (about 2,1 cubic inch). The idea is that if the meter pipe is big, its possible to use more of the propane before the can is empty.
Feel free to correct me if im going down the wrong path

Shineh!
Looking good, this is going to be a badass combusion

i have given up on getting the pvc needed for the cannon i want to build, 3weeks of searching local dealers for parts, and no luck 
..
So i whimped out, and ended up with ordering the pipes from Mike at ulimatespuguns. ( bl520 )
metall work is no problem for me, so ill make the other parts needed when i get the parts
making a 0x cannon in metall makes it too heavy. and pp soil pipes are no good. thats my alternatives.

im trying to find a tread talking about how much burst disc a normal pvc cannon can take (with ammo in the barrel). and is it safe safe to take a pvc to 1x ? .
im not trying to be spoonfed here, but i have a hard time finding what i look for

1x is technically a normal combustion.
0x would actually mean there's no air in the chamber
If you mean using a normal pvc gun at "2x", or with one additional atmosphere of pressurized air/fuel in it, I would strongly advise against it. If you want to remote-fire it from a distance, ok, but don't try to shoulder the thing.
One member (I think it was noname) blew up a sch80 hybrid with 2x. In theory it can take the pressure and still have a significant safety factor, but there is no way to test pvc pipe for internal defects and fatigue.
