so what i want to know is how i can make these operational from a distance. so i have a sg. i pop it open and cut the wire going to and from the switch. then i lengthen the wires. but wouldn't the longer wires lower the electric level due to resistance? makeing the perfomance of the sg probably not...

That should work. Thanks, Pete!

I was taking it easy. That's why I was enjoying this moment for some comic releif. Yeah, I knew about just as much when I first started. Then I discovered the joy of the forum search key and spudwiki. Two lifesavers. No harm, no foul. But just for the record I did spend about an hour searching the ...

Probably a noob question. I'm almost done building my first gun, but I'm having trouble with the threaded fittings. The male fitting is NPT Sch80 PVC, and the female fitting is NPT Sch40 PVC (this is for a combustion gun, I couldn't find the male fitting I needed in Sch40). Anyway, I can't get the m...

But a remote switch is dangerous. Any wirless signal (old cordless phone or a remote control car) could cause it to go off at any time. Wouldn't try it. Not true. Well, I guess you COULD set up a wireless remote system that could be triggered by anything. But it's not hard to make it safe. I have a...

Pete, those spreadsheets are great, thanks for sharing them. Unfortunately I already bought some 4" sch40, and after reviewing the pressure and temperature derating charts for sch40 I've decided putting more than 20% of the chamber volume in oxygen with sch40 wouldn't be a good idea. I'll probably s...

Can anyone tell me what it is about the exhaust gases that causes a problem? Does carbon monoxide interfere with combustion or something? I figured as long as there was a stoichometric mix of fuel and o2 it should combust nicely, unless there's something that reacts with the oxygen.

Cool! Thanks, Pete!

I'm building my first spud gun, and am starting off simple. It's going to be a basic inline PVC unit with a stungun ignition. But I expect at some point (probably soon) I'll get tired of opening the base cap, ventilating, adding some guesstimated amount of fuel, getting irregular performance, etc. S...
