For those of you who've built triple wickers-

Assuming that you're wanting all the wicks to burn a similar length of time, have you found it necessary to make the wicks furthest from the handle bigger than those nearest, to account for the fact that they're travelling faster through the air and presumably getting more oxygen?

i.e. for each poi would it be best to have wicks of increasing size as they get further from the handles, or should they all be the same size?

Or does it not make much difference?


(I notice that the triple headers in the shop all seem to be the same size-

I'm not sure it really makes that much difference, the tripples I make tend to have some variation in burning times, but then so do my singles, though it's not just wick size that affects burning times, since larger wicks tend to expose more surface area and thus tend to burn more fuel. I have made tripples with differing diameters to account for variants in rotational speed, but frequently found it didn't really work out as intended.

Posted:It might not work out as intended, but if I were to make triples I would probably make the end heads a bit bigger if only for balance issues

Posted:for my doubles this is often the case...the wicks at the end go out before the top ones do almost every time....

so one would think that it would also matter for triples...

Posted:Having done 3, 4, and 6 wick poi, I can tell you that wick size is critical if you want an equal burn time. Some very rough numbers... For my 4 wick poi, each wick was separated by 6 inches. Individual wicks were tube-core design, using 18", 24", 30", and 36" of wick. Could probably have even used a little more wick on the end.

Those pics are incredible! 6 wicks a hand! They must be incredibly expensive...

My applogoes for not mentioning the password thingie. My friend who runs the site found that to be the only way to keep robots from downloading all the images in his site.

The six wick poi are actually nothing more than my 2-wick poi linked up to the end of my 4-wick poi. As silly as I thought the 4-wick poi would be when I was making them, I still left a hook on the end for future expandability. I build all my own gear, so the only costs were time and meterials. Still and all, that's 17 feet of pick per side, 34 feet total.

And yeah, they are freaking heavy even before you soak them. You get quite a shower of kero when spinning out, too. Hardest path, though, is the length. At just over 5 ft overall length, you're holding the wicks at shoulder height.

I've only ever spun them in that configuration twice. The pics above were from the first time. The second time I did it was just to prove that I could do a full burn without burning myself. (I'm not sure pics ever got taken that time.)

Unfortunately, I never really liked the construction method I used on the 4-wick poi, so I disassembled them for the kevlar and reused it in other projects.

Posted:There's actually a "trick" to spinning heavy wicks. Instead of using you hand as the center of rotation, try to shift the center of rotation 6-12 inches down the chain. It's somewhat hard to explain, you just need to try it. You'll be making larger, more exaggerated, motions with your hands. Personally I find this to be much more expressive, and it works with the slower, more downtempo music I prefer to listen/dance to. It also works well to dance to irregular beats. Most spinners seem to hate irregular beats, so that's when I take the opportunity to rip it up on the stage.

Posted:When I play / practice or perform with heavy or tripple and quad burners i use tripple finger loops to reduce the load on fingers, also i tend to use a much slower more expressive style of performance, incorporating much more movement in terms of exagerated moves see above comments by pj, also i'm not sure if this makes sense but i tend to follow the heads rather than keeping a tight style of performance, overall the effect is to move with the performance and adopt a much looser style

Posted:You are right that the outer head should be bigger. This can be achieved easier with "tube" type wicks. We have played around with this a bit in the past. We have just produced another size monkey fist which will help.
With current design we normally put the whole set out once one head goes out. It is very unusual even for single headed poi for the heads to go out at the same time.

Ideally everthing that we spin should be a slight conical shape.
We want to factor in centrifugalforces taking fuel to the furthest points as well as the further away poi head having a larger surface area and hence makes it burn it's fuel faster and possibly requiring a better capilary efffect to feed the flame with the extra air racing past.

If you move the center of rotation (or adjust chain length) then all the ratios between the sizes required and the speed/travel of heads will change.
A great challenge. As always we will tweek our designs for improvement

Posted:i am about to make some triple headed poi with smaller monkeyfist wicks. i'm thinking that i should make the 1st knot (the one closest to the handle) with 2 wraps for each direction. the knot in the middle would have 3 wraps and the last know would have 4. this way the size of each monkeyfist will get bigger as it gets further away from the handles.

the other oprion would be to do the 1st 2 knots with 3 wraps and the last knot with 4.

example of a monkeyfist with 2 wraps

so which design?
