Folding Finger Spinning Fire Fans

Hi All, I'm a bit quiet on these forums, but in short, my names Charlie, and i design and build fire toys, the one i make for HoP is the folding fire fan HERE.

I have decided to start my own thread rather than continue to hi-jack an assortment of other peoples threads on fire fans.

What i have been working on for some time is a folding finger spinning fire fan, this has been a 2 year project (along with about 8 other projects I'm working on simultaneously).

It was set to be released on March the 1st, however about one week out from the release date i hit a sizable snag, the company that produces the springs I use on the fans could not physically produce the spring they had sent me samples of.

WARNING - Tech Speak
The spring needed for the finger spinning version of the fire fan needed to be almost twice as strong as the standard spring to fight the effects of inertia while spinning (or simply, they have to be stronger so the fan doesn't just close as it spins). The samples had been hand made, which produced a tighter coil with higher initial tension than the machine which was going to do the mass run.
/Tech Speak

So, that said, this design is delayed indefinitely until i can find a company that has a single point coiling machine, or can hand coil me 100m+ for a reasonable price, as the alternatives to not having a stronger spring make an expensive prop even more expensive (around a 50% increase in the price as opposed to a 15% or 20%).

I'll post updates here as they happen, as well as a sneak peak photo and maybe a video of the prototype i made with the sample springs.

gah, that's depressing news, Charlie. I'll just have to keep my fingers crossed that you'll have success on that soon. Now I have to decide if I want to hold out or buy the original fans of yours.

le sigh

UPDATE

I have found a manufacturer and am testing a sample of the required spring.

Joy of all joys, if I have no further hold ups i should be able to get this project back on the road ready for release in a few weeks

Approx RRP on these is looking around max of NZ$250+GST (if your outside of NZ you won't need to worry about the GST) I will be doing everything i can to lower that figure though, my Target is $225-$235, as I am very much aware that to my knowledge these are by far the most expensive Fire Fans in the world... though perhaps one could say they are also the most advanced

An upgrade Kit will be available (initially) at the price difference between the standard and spin version so as not to disadvantage those who simply couldn't wait to get there hands on them

how does the upgrade work?

The upgrade will simply be those components which are different in the spin version, i.e. the center blade and springs. Will probably knock up some instructions to go with the kit as it requires complete disassembly then reassembly of the fans.

That looks really good actually. Do you have any footage of it lit? Would be really cool to see....

I have some footage tucked away somewhere, though none i can lay my hands on just now.

But here are two special sneak peaks in one photo for those following the development (I'm looking at you squid )



The above shows the 7 Blade prototype, and size/shape/placement of the prospective ring. (note that in this photo the ring is just resting on top of the centre blade, it will actually have a full hole in the centre )

The only assembled finger spin prototype was destroyed during Product Testing at Kiwiburn not that I mind, my philosophy is simple, if you can break it i didn't build it right, go have fun. Admittedly the death blow actually came from being accidentally danced on instead of danced with, funny stuff.

Haha, how did you manage that? I mean, I know that we NZ'rs can be clumsy sometimes... But to dance on it?

Keep us posted though, I'm interested, even if I'm more of a staffer... You never know.

I'm not sure how it was managed, but of all the sets of these fans that have come back to the workshop for repair, underfoot manipulation is the only cause of damage, normally i can straighten them out, but the prototype set were a write off.

The Staff/Fan combo can look quite cool (if I do say so myself)

I was briefly contemplating making a bullet proof stainless steel version, but they were going to be too heavy to be feasable, and one of the most common things i hear back about mine is how happy people are that they are light (around 350gm each)

So these are made of aluminium as opposed to steel?

Actually, just considering the fan/staff combo..... I suppose it could be interesting if you mounted the fan into both ends of the staff, effectively having 14 mini flames on it... Only thing I'd be worried about is getting them caught in my shorts.

Yes they are constructed of NZ Smelted and extruded 6060 T5 12x3mm 1.5mm Radius Edged aluminium

I would not recommend that with these as any drops or accidental ground touches would be catastrophic... For my staff/fan I had staff in my right hand and fan in my left and away I went.

If you like the idea of a mega-multi headed staff look up 'Dragon Staff' i think Gora or someone over on the European side has made some pretty cool ones. http://www.youtube.com/watch?v=XarnEF2FuKY

Nice.... Smelted in Bluff?

Mmmm, the other thing with the staff/fan combo would be the speed drop...

Actually, that dragon staff looks dead cool. I think I'm gonna have to build me one sometime after I build my main one....

Ok I am officially psyched!! I'm following this progress with keen interest!

Would the thing be painted? I've a pair of HOP large fire fans, and the paint job has speckles of paint that will be harsh on the finger when spinning. I guess I could always sand them down, but just saying.

Also, I'm interested in the dimensions in terms of length, though if I can use the large HOP fans with 6-inch light sticks attached to them, this pair of amazing fans should be no bigger than the regular HOP ones right?

Can't wait for this product to come out and congrats again on having overcome the spring problem!

Hey There,

It will not be painted, though in future i am investigating powder coating them, it will be bare aluminium which has been filed and sanded on any rough spots to ensure comfort of use.

The dimensions of each finger/blade are 40cm long which is just under 16", the span when open is 80cm or 31.5". The wicks are small at 5cm or 2", but a 10cm/4" version is in development at the moment which will have a slightly larger span to keep the flames a comfortable distance from the hand.

Thanks for your questions

Ooh one last question: will you sell wickless versions of the fan too?

Yes it's in the works that I will be selling such a version, TBA if HoP will stock it though.

Charlie, I have to say that the fan looks fantastic, I have not had much experience with them myself, but I have looked into buying them in the UK and these are far superior to the ones available in shops over here.

Thanks for your feedback Grottbags

They are simply like any other folding fan with a bit of modern technology thrown in to replace the leather straps or chain, to me the design was the obvious step forward and evolution for them.

I think in time other designs and manufacturers may follow suit (imitation is indeed the sincerest form of flattery, and each time it happens i take it to mean my design is spot on), i am aware of one hobbyist fire toy manufacturer who has very closely replicated mine, however instead of using springs he has used stainless steel cable, which works in a similar way though the stainless will fatigue eventually and cease to operate as a spring (which is why I don't use it).

It's definitely a goal to have these distributed by someone in the northern hemisphere some time, so they can truly break in to the northern hemisphere market.

Just a quick update.

Problems with the new manufacturer, long story short, they are going to charge me twice the quote i accepted... le sigh.

Enter a thought that popped in to my head as i was running home from work today, the only issue is, does it look any good? Chris and I were not fans of running two sets of springs on their own bolts etc, but it occured to me that two springs could run off the same bolt, keeping cost down and actually making the fan function better.

What do you think? sorry for the bad photo quality, but you get an idea.

open: they look cool. I like the ellipse it makes. Kind of reminds me of an eye shape.

closed: looks bulky. Im trying to envision what several of them would look like together when they're all bunched up.

Its a minor gripe though when it holds the potential of keeping the cost down and improving function. Besides which, few folks will be looking at the hardware when the wicks are lit.

Do you think the bulk of all the springs would interfere with being able to slide your hand up the shaft and hold the fan in the middle?
