Is burning steel wool with a 9v battery okay?
Is sewing thread fine as a monofilament?

Re: General Questions
Depends on what kind of thread you use. I used a nylon sewing thread, which is a monofilament. It also burned quite easily.

Steel wool I'm not so sure about though. I don't know if that's a conductable or not (assuming that's the step you're talking about). A 9v battery is kind of big. We used a circuit from 2 D batteries, and that's only 3 volts.

There once was a group of teens
Who were lean mean science machines.
They liked to win medals,
when everything settles
and their favorite color was green.

That works, we tryed that too but the thread is way too weak, fishing line FTWcourage7856 wrote:Depends on what kind of thread you use. I used a nylon sewing thread, which is a monofilament.

courage, I was not planning on using steel as the monofilament. I was using it as the heat from resistance thing.

Re: General Questions
Okay, that's what I thought you were doing (more or less). We had smoke too, and the judge was like, "Is that okay? Your device is smoking." We said that it happened all the time, and the guy just shrugged and didn't seem to care. Our coaches and our varisty counterparts (who competed right before us) were cracking up.thepotato wrote:man, your judges must be really harsh. I used string as the mono, steel wool for the resistance, and a brushless motor, but the judge didnt mind.
and I had smoke
I just realized I called steel wool monofilament. Wow. I really am tired after state.

Re: General Questions
OLD RULES stated that small amounts of smoke and odor were okay. All those years, three Missions flat-out ON FIRE (flames licking up the sides) and countless mostly-odor devices, and I never assessed the penalty. Why? Because smoke, stink and fires are fun, that's why. Free publicity, too. And when is it "excessive"? When even the BDU dogs are running for the door?
It really isn't addressed in this year's rules-- sort of. I won't encourage the burning steel wool, though, because candles are banned. Nat'l Sup himself also said, "no flames". Argue all you want about whether burning steel wool has flames or not (maybe reconsider after looking at under IR and UV light-- surprise!), but at almost all tournaments, you can't appeal a safety issue. How well do you know your event sup? A sympathetic sup can over look a few strands of steel wool without risking career & reputation, but a wad the size of a bar of Irish Spring is a different matter-- another coach sees and arbitrates, and it's suddenly out of the event sup's hands.
All tournaments where I have final say are done, and I have otehr issues to deal with; maybe a clarification needs to be sent in by someone (don't mention IR or UV observcation, though!). I AM curious, however, as to how it works out, bothy clarification and actual tournaments.
