Visco Fuse Machine

- An automated Visco (Safety) Fuse Spinning Machine. I built this myself in the spring of 2011 at Franklin W. Olin College of Engineering as a Passionate Pursuit. I designed and built a visco fuse (safety fuse for fireworks) spinning machine. It takes 20 spools of thread and wraps them around a black powder core, and then coats the 1/8" fuse in a waterproof nitrocellulose lacquer. It operates at a speed comparable to commercial machines and is built for safety; it is entirely non-sparking and removed from ignition sources. I designed it completely from scratch and machined all of the parts in the Olin machine shop.
Plans for this machine can be found at www.pyrotechnicmachines.com
See www.olinproject... to see more about this project or other projects by the students at Olin College.
One of the best homemade visco machines i've seen, although it burns faster than normal visco.
Very nice work there Robert.
Boy that's slick as hell. Well done Sir.
@Fishingwithexplosive It's a modfied black powder formula to burn a little slower. regular bp will make a fast burning fuse.
I need this machine lol!!!!! Great job
Dude, you are awesome!!
Robert I'm very interested in how these machines work did you design & build this machine yourself. They're quite mesmerizing. Thanks for sharing the video
very similar to mine i built one out of knecks just to se it would work and suprisingly it did. you can call it a prototype now im going to build one to last and work more efficiently
That would be pretty cool if the school were called the Franklin W. Olin College of Engineering as a Passionate Pursuit, but it doesn't seem to be the case on their website.
also, when you say you had a fast BP, was it a well milled 75/15/10 mix? I was thinking to myself just this afternoon that a standard ratio comp might be too speedy, perhaps a 65/20/15 mix?
@z3nx10 Its dipped in Nitrocellulose laquer before winding. This sort of glues it together and waterproofs it.
How to make it as fast as you? Can you give me specific ingredients?
Hello, can you pleas send me Plans for this machine? Thank you
1/8th is a bit big for visco,have you figured out how they get commercial fuse down to 2mm is it the string diameter most homemade visco machines make more like a timefuse.
Burn speed has little to do with the manufacturing process. I only had some really fast BP at the when I tested this, but burn speed can be controlled with the BP composition.
@octavio2895, try making the hole in your top spinning die larger and/or add a larger chamfer on that hole. Or else you need more threads on top.
@Fishingwithexplosive Opposite ways. That's why one is a gear and the other has a belt.
Old video but do you have any valid links still or can you email me some info on the process you used to design it?
Thanks
Beautiful machine, fuse is Way too fast for my tastes but you may have different purposes
hi nice machine i was wondering if you can help me with mine, then the gunpowder (meal and granulated) is applied it falls off and it doesnt get inside the threads. could you help me?
hi there, really nice work, ive probably dreamt up 1000 different ways of making one, now i dont have to. Would it be ok to post this on a legitimate pyrotechnics forum with all credits to your name? Very very useful info. again many thanks for sharing with us.
This machine is amazing where can someone learn how to make it?
@octavio2895 Maybe your BP is too Granulated? Or your second plate isn't running fast enough?
Do you have powder wastage with your machine ?
how many spools and wich one has to spin faster my visco fuse machine is bult but i think i need more spools
great job 5*
Nice!
@mayhem. Yes! Definitely. Yes, I'm using standard, 75/15/10 mix, and with ultra-fast home-cooked buckthorn charcoal. (It's a great break charge, but its way too fast for fuse). Sadly, I've been away from my machine for the past year, so I haven't had the chance to experiment with any other compositions, but adjusting the burn rate is entirely a formulation problem, it really doesn't involve the machine.
@ megara13. All the numbers are now available on my website (see above description)
does it go through the NC laquer before it goes onto the holding spool?
Do you want to make another one and sell it? Name your serious price please!
How is your fuse staying wrapped? as soon as i cut mine it un-twines for a good 2 inches
Plans are up! (see video description)
Its still a bit of a work in progress, although there is quite a lot up right now, and more to come soon. I apologize for the web design, or lack there of.
Талант!
Do you have a cad file or something for this
What happen if you put flash powder instead of black powder ? ^^
Is it possible to buy this spindle machine?
What does "visco" fuse mean?
Nice machine!
Can you share the ratio speed per circle?
thanks
Cháy nhanh quá bận ạ.. có ngày mất tay
Could you build me this machine at a reasonable cost for your time & labor
can you make a tutorial?????? or how to or somethin
What was that white powder you poured into the funnel? It didn't look like BP to me.
Sugar. This was in a college dorm, so black powder was frowned upon.
+Robert McMullen Ahh, smart thinking! Nice machine by the way! I like the compactness of it.
Robert McMullen could you please send me the plans for this. My nephew and I are in the pyro hobby and this would be great to build together. I can send you my email if you are still willing to share the pans. Such a great machine!!
Could you please tell me where I can find the plans for this machine? The website no longer exists
Tutorial tube visco fuse machine
Nice worck dude can you send me the build info i wich to build me to :)
Can you sell me a fuse winding machine
Can you send me the plans?
Price
Price machine?
Can you sell me a visco puse?
máy nay bán làm sao
Can you make me one?
Motor how much v
очень быстро горит шнур
muốn mua máy này có bán ko
Tuan Duong tự lam thui bn. minh cũng lam 1 cái. dùng dc
Sold where do we send the money. Lol
i mean WTF? :D
i need this^^
Bro this fuse buy
5+
😋😋😋💜💜💜
I was just kiding dude,relax..
I am willing to pay $500 for this machine
