Black Bush Poi design

Wear a sweatshirt. A sweatshirt thicker than an engine block. Duh.

the thermite is what burns through the engine block, the magnesium is just needed to start the thermite
an idea ive been working on is a cage built in layers, but the only issue i keep getting is that it takes about 5-10 min to "reload" the cages w\ more wool
another design ive been using holds around 10 pads of wool in each cage, but the issue of the wool compacting on itself is really becoming a mad pain in the ass, pretty good show though........ive been getting a burn time of almost a minute of solid streaming sparks...working on making it to 5 min or so...any new designs or ideas ill def. post because this has been an issue of mine for quite some time
oooh and anybody that has a pic of these black bush poi things should get it to me, i could probably improve the design and get back to you w\ me modifications

link topics of black bush poi??
at the top of the page mate

right then guys seriously now, a little bit of research is needed. if this magnesuim is safe im going to do it. if its not safe im not but if it is then i will. but if its not then i wont.
yes??
or
no??
my theory is that the cages spinning will force all the sparks magnesuim etc out of the bottom going in a harmless arc away from me as does the red hot metal of the molten Wire wool.
or will it mould into a huge ball of molten metal with the magnesuim inside which then ignites and expodes spraying huge amounts of molten metal into my face.
i could do with finding out before i do it.
im going to do my own research but as they say two headsa re better than one

dont understand whenever i do sparks they always compact in on themselves and its the g force forcing its way through forcing the metal to sqeeze out of the bottom that causes the sparks.
it also causes big molten lumps. are you sparking differntley to me.??
if so how.?

magnesium wont explode...not the way your thinking at least, thats a combustion reaction......only when you mix mg with the proper chemicals will it to that
but magnesium i think is the hottest burning metal out there w\ temperatures higher than the temp of the sun (ie LOOK IT UP!!)

on the topic of my cages i use .....erm....methinks its called chikenwire
either way its very strong (hard as hell and time consuming to shape properly), its of a metal that conducts heat very very well so when im spinning the metal doesnt melt, i use 0 guage (sp?) and 00 guage Steel wool in combinations, and the cages have a crosswork so that the wool gets airated and throws the sparks
remember to get the sparking effect you need oxygen to fuel the heat...(any sort of combustion needs 3 things....air, fuel, and heat)
either way if you get a few pads of 0000 guage Steel wool and connect a 6v battery to it
youll see it start to glow, and burn, now blow on the wool and it gets much brighter...also means that its getting hotter, the brighter it is the faster it burns, and the less amount of sparks thrown off

just an example...this was before i got the design perfected..bout half the size of what i do now.......if i can figure out the time element then ill def post me findings.............so yeas......
IF THE IMAGE DOESNT WORK SOMEBODY TELL ME HOW TO DO THE DAMN THING PROPER!!!!!

oi....are you talking bout the cage poi....? they are so easy! i used them on like my second time...so easy...btw im not bragging about it, im just saying it depends how confident you are and all that
rock on-kat

well...this is an odd thread to bump as your first post


I think these black bush poi are extreeme versions of wire cages as you can *really* pack in the Wire wool tightly into the whiskey tubes.

the link isnt working for me

Firedanceuk.com is down.

Jo and Liams Black Bush Poi design was a very extreme form of cage poi; a mistake while using them could be very, very dangerous.

Due to the large amounts of Wire wool used and the heat from long burns, they tended to throw off largish chuncks of molten steel.

Jo put pictures of a nasty scar that resulted from using them, luckily it was on his chest, but still harsh.

Although dangerous and requiring a lot of prep for each burn, the results were exceptional- after much development they were getting minute-long burns of the best sparky poi I've seen.

VERY!
(nice)
(sparky)
(+horribly dangerous)

Now have a few bits and bobs regarding my own design of cage poi.
have a look at www.fieldsoffire.uni.cc
www.fieldsoffire.cjb.net

What a surprise to see this thread still going!

Shame the old pictures and video's aren't available though.

Kat, I think you should respect sparkly poi of any type as by far the most dangerous type of poi. You must respect them a lot, but even so you will still get burnt. Always be extremely careful and always wear goggles - no matter how good, confident, or brave you are.

I once watched a guy spin wirewool on a street in a residential area who couldn't even do 3 beat weave. It was cringeworthy to watch

so....let him torch himself...laugh at him for being an idiot.....laugh for a few more minutes...then put him out...
if u let him burn long enough he will never pick up another set of fire poi

*runs off to go get marshmellows and sticks

That's some dark poetry right there

arent you a cheeky bloke.........


if i ever get around to it ill post how i made my cages..i get around a 3-5min wool burn

I joined so late that I've never seen the old pictures.
Any chance for a new one?
I would like to make a couple of cages and practice a _lot_ with
them before actually putting wool in them, and even then I'd
probably stick to a simple 3-beat weave for some time
I would very much like to not make the same design mistakes
that you've already corrected, but trying to imagine the cages
from the comments is too hard for me.
I'm personally not surprised that the thread lives... sparklepoi
just looks _too_ nice for me not to try it, but I fully realise that
it's a huge step up in danger from a simple burning wick.
Any advice, save for forget it or don't do it, is very much appreciated

No comments so far...

Well, I'll throw in a more direct question..
I am assuming that the bottom of the cages is wire mesh not matter is all of the cage is or you have solid sides.
I would like if someone could post measurements of the mesh they use; wire diameter and holesize, to get an idea of what works best.
I also assume that if you use solid sides you would have a distance with mesh sides at the bottom to allow increased airflow to the wool that is at he very bottom.
If so, how long?

/Dennis

I worked out that having holes at about 1 1/4inch to 1 3/4inch works best. You also need a curved (bent outward) bottom, or else the wirewool will clump.

And since no one wanted to post new pictures I took some. These are not the blackbush poi, as I don't like whiskey enough to buy 2 bottles to make poi out of.

Instead these are made from coffee cans. Not the big fat ones, the slightly smaller ones. The wire is just chicken wire I picked up at Home Depot. Had to buy a whole roll but just used the rest for an anti-cat-escape fence on my back deck. I used a thick coat hanger on the end to attach the handles to, which are of course your average dog chain from the pet store. Were the wire starts to curve off the can, i poked holes around in the can and used utility wire to attach wire to can so it doesn't fly apart. To make the curve I had to cut out chunks of the chicken wire and form a dome and wire it all together.


The setup, they are roughly 8 inches long from the top of the can to the bottom of the wire, and about 4 inches wide.


This is the end of one of them, you can see i had to poke holes through the can to attach the hanger, and your standard link to attach the chains. I have the wire bent over inside the can to it doesn't snag on anything.


This is looking down into them, you can see about the size holes I have used.

I have noticed packing the wool differently has an effect on how long they burn, if you break it up (fluff it), not just shove chunks of it in, it seemed to make for a better and longer show (something around 45 seconds to a minute).

The only thing that would be better is if they where a bit heavier, you have to work a little harder to make the sparks fly. Pretty easy to reload as well (after they have cooled off of course).

And finally

In action

Any questions let me know.
