Okay i know you may be saying you can find this all on the search but i did search several different occations actually.
My first question is what is the best way to get 2 or 3 different sparks other than a spark strip or latke's chamber short?
Secondly if you have a fan that says a running power of 12 volts and a switch to turn on the fan rated at 10 volts can you run this stuff off of only one 9 volt battery?
Thirdly do BBQ sparkers run off of battery or not?
And very lastly hopefully is i know that pneumatics can not be used in winter but can you use a combustion for extended periods of time at foresay 40 degrees fahrenheit.
Any replys will be greatly appreciated for i am very confused with these.
Saecond Edit:Just in case you were wondering heres the link to the switch i am using.http://www.radioshack.com/product/index ... age=family
Questions for my semi advanced combustion.
1) check out advancedspuds.com but unless you have a super long chamber, i don't really think you'd need two sparks, i just use one and it works fine 2) I use 12 volts for my fan, I think 9 volts would run it, just slower, but i'm not positive 3) no a BBQ sparker doesn't need a battery,
4) search... http://www.spudfiles.com/forums/prevent ... 11568.html

"Some say his pet elephant is pink, and that he has no understanding of "PG rated forum". All we know is, he's called JSR. "
im building an advanced combustion at the moment too and i am using two 9v batteries to run a 12v chamber fan.
basicly the 12v means that it can run almost indefinently without over heating at 12v. if you run it at 18v for a short period of time like i am it will not hurt the fan. just wire it in series and it will work a lot better, trust me.

BBQ igniters run on piezo-electrics so no they do not need a battery.
no, thats called parallel wirering. it would work, but you would still have 9v. to get 18v you need to wire it in series, like this-

see the difference?

yep, exactly like that.
edit- go to radio shack and get a project box to put the batteries and swich in, it makes it look really nice as opose to if you (A) try to build the box you self or (B) if you just tape it on the side. its worth the extra $3 or so.

Sorry but i have one more question. I looked all over but i just want to make sure that DWV and ABS are different materials. But which is better in combustions ,ABS right 
I would really like it if my cannon did not explode in my face. :violent2:
I would really like it if my cannon did not explode in my face. :violent2:ABS is what the pipe is made of, DWV is what the pipe is for.
ABS is a type of plastic, DWV means "drain waste vent".
most abs is dwv. so your pipe is probably both, but abs is extreamly durable and is actually my preference over pvc, for combustions. for pneumatics you want to use pvc.
on my cannon that im working on i am using DWV ABS, ive made several combustions with it and have never had any problems.
just out of curiosity, what is you chamber diameter and length?

ABS is great for combustions, it is still dwv for works great for combustions as it can withstand the pressure shock better than pvc. ABS Works great

DWV is a type of pipe. I think what you are asking is "Which is better for combustions, PVC or ABS?"
People claim that ABS is better for combustions because it holds up to shock. If it fails, it tends to split instead of shatter.
I, personally, have never used ABS pipe so I would not know. I do know that I have yet to have a failure with PVC. But, hey, if you got it, go with the ABS. These people are pretty smart here.
By the way; I just love that exploding smiley.

I have all my specs pretty much worked out. The things going to be huge. The chamber is 3 inch 20 inches long and the barrell is 1.5 inch 70 inch long. Is this even a reasonable size? With all this the C:B ratio brings it up to a 1.04:1.
