I need your advice

Unread postAuthor: itwentboom » Thu Mar 01, 2007 6:23 pm

Recently i was asking for info on building a twin chamber combustion cannon. I am stuck again on the ignition part. I have a 100,000 volt stun gun ignition and i am trying to wire both chambers. I can't seem to figure out how i should wire both together any info would be great.

Just run a circuit between both of them. Ummm cant draw a diagram so I'll try and explain my idea. Set up the ignition on both sides as normal axcept instead of the wire coming back to the negative/positive terminals just connect a wire between one bolt on one chamber and another bolt on the other.

P.S. Hope it helps I suck at explanations :P

Please look at the wiki before you ask things like this. Im new so I dont get anoyed at questions yet but there are many who do.

That aside, I would wire the gaps like this:

WHAT I have probably read that thing more than anyone in here. This isn't my first cannon and my question i think is a good one. I always research what i am doing and couldn't find anything on it thats why i asked. I wasn't sure i could seperate them that far. Thanks for the info.

I think this is the wiki entry you would be looking for. It doesnt explain your exact scenario but the same principles apply.
http://www.spudfiles.com/spud_wiki/index.php?title=Spark_strip

Edit: Imablackskater: you could wire them up either way, I just wired in series instead of parallel. I guess in parallel you get the same voltage but half the amps. In series you basically get half the voltage per gap, but being he's using 100kv that shouldnt be a problem.

And you use less wire.

Dude that is a spark strip? In no way shape or form does that show you duel chamber spark ignition. I only asked this because i wasn't sure how far apart the wires should be. I have ran duel spark before with a bbq ignition i just wasn't sure about duel chamber ignition. And there isn't anywhere on Wiki that shows or tells about it. "TWITCHTHEASSIE" said all i need to know. I didn't need you to tell me to read WIKI before asking these kinda ?.

Sorry, but I didnt know you only needed to know how far apart the wires should be. From how you worded the question it sounded like you needed help with the whole circuit.
(twitchtheaussie beat me to the reply cause I was drawing the diagram)
About the wiki link, a spark strip IS actually what the diagram depicts, but with part of the strip connecting the chambers.


Anyways, peace, and sorry for the confusion.
