Hello!
I'm a new Israeli user on this excellent forum and I want to share with all of you some information about my visco fuse machine
So here are some pictures of the machine:

I built it according to the design on this website: http://truetex.com/visco.htm
It has drawings of the machine and I built it exactly like the drawing said and it was not very accurate. I had to do some modifications to suit the right pulling-winding/spinning ratio. The optimal pulling- winding/spinning ratio that I have found is 4.5cm to 4 spinning of the wheels. So I have almost 1 spin of wires on 1 cm.

I used pine tree charcoal BP very fine BP and a homemade nitrocellulose coat.
The fuse can be coated with a ping pong ball nitrocellulose.originaly, i had needed to use cotton wires but i used polyester wires and it works fine .
From the fire test that I have made I found that the fuse is burning in 0.7-0.73 sec to 1 cm.
My fuse can burn underground and threw more then 5 cm clay sealing but I didn’t succeed to make him burn under water because I need to coat it with a thick nitrocellulose layer and I didn't succeed doing that.
The thickness of the fuse is 1.6 mm thinner than a match you can see it on the picture above.
Here is a video of the fuse burning threw a 7 cm clay sealing:

If I will make a comprehensive tutorial with pictures and test for building this machine, will it be enogh for getting into the info pool?

Well…. I hope you will love my machine please write comments

Very interesting. Do you have a specific peice of equipment for the NC coating, or do you do this by hand?

I remember seeing the same page in the link provided from the UK rocketry forum. One guy made a machined aluminium version with the "spinning wheels" virtical to eachother. I believe the comps for other fuses like flying fish are on the visco patent.

This is one of those many things on my father and I's project list. :P
Good video, I wanted to know how it performed before hours of work went into mine.

Its great to see new users like Star Roller and youself making such a great contribution to the forum :)

Preitty cool. Talk to the mods about the project for getting into the info pool, I don't see why a tutorial like that wouldn't get you in.

It's funny all of a sudden in the past 6 to 8 months it seems like a bunch of homemade visco machines have poped up, when none could ever be found before, usually just some shitty idea about filling a hollow cotton string with BP slurry.

Very nice.

Kilo is very right, all of a sudden, these visco machines have just been "popping" up. I think I should try but as I can get visco so cheaply at the moment, I just haven't had the motivation.

That is a very nice machine that I believe the ametuer can build, unlike some which need alot of metal working to construct. Please do write up a tutorial for the info pool for us to construct our own.

thanks, i'll write a letter to the managers about the guide and the info pool.
Mr. yuk i dont have a specific peice of equipment for the NC coating, but im working on it :)
i know that no body knows what is the specific mixtur of the "flying fish" fuse but if sombody knows a mixtur that will work as good as the "flying fish" fuse please tell me it will be very usefull to me :)

This is a neat little machine, I read that website, the origional link is from a google forum. I made one almost exactly like the one in the picture about 4 weeks ago, the only problem I had with mine, was the thread wouldn't seem to wind correctly. It would just sort of twine togeather and make a mess. I will probly work on it some more soon, I got tired of picking at it and trying to make it work. Good job with yours!

Thank you
maybe the problem is in its "nozzel"
did you tried to make the grooves more deep? like on this picture:

my machine never did any problems concerning to the wire pulling.
in fact it has never did any problem at all it works smooth
if sombody knows a mixtur that will work as good as "flying fish" mixtur please write it down

do you have a video of the machine in action because I still have yet to see a visco machine at work

Once the fuse has been formed, where is it taken up at? Does it simply wind around the shaft of the handle as you turn, or do you have to take it up manually elsewhere?

Ah, I see, looking at your nozle, I see it is very thin, a few mm's by the look of it (unless you have giant hands B) ) where as mine was copper pipe, with notches grinded out (yes they were descently deep and thin enough to keep in the wires) but the fact that the entire nozzle was 1/2" is probly the problem. Maybe I can get mine to work afterall. Thanks for the tip.

To frank,
like you said it simply wind around the shaft of the handle as I turn the shaft. then I disconnect the drive band and turn the shaft backward that causing the fuse that was formem on the drive shaft to release.

ZoSo57, thanks
if you can and have the right tooling, try making a nozzle like mine
you just need a special drill like i this picture:

and i dont have huge hands actually, they are quite small
well when i'll finish the guide you will get answers for all of your questions :)
but for now, if you have more questions please ask ^_^

Thats looking nice Sason.net...Kilo my theory is that nobody amateur ever tried making one because we all believed Visco machines were beyond our skill level and were a specialist tool used by the professionals. All it took was one entrepreneur to realise hey, I could make that, scaled it down for home use and showed the rest of us that it was possible which has pushed us to make our own.

you are right,
it is true that people deterred from making a homemade visco machine because of the reasons that you marked.
the fuse is very good it is accurate, but still, it doesnt reach the quality of a commercial visco.
i dont say my fuse suck actully its very good but commerical visco is better.
after all my thoughts and considerations i got to decision that it was very worth to built my machin and make my exelent visco fuse:)

Yours looks great and you really couldn't expect any better with a machine made with home handyman tools. DIY visco machines are now in the reach of all amateur pyrotechnics and I'm sure that soon it will earn its place next to the ball mill on your garage bench. First I have to build my new ball mill...

I'm impressed... It's real nice but for 10 dollars you can get 50 feet of fuse.. Is it really worth making a machine to do it?

Maybe if you have no access to fuse then sure.

In Israel you can't buy visco.
And building a ball mill, visco machine or any other pyro tool is fun too in my opinion.

Like quest said you cant buy visco fuse in Israel so its really worth to make and you can earn the cost of the building metirials by selling some fuse
well im talking about israel I think that in your country no body will buy your fuse because you have a free access to visco in low prices
and if you earn the costs of the machine you can make yourself hundreds
of feets of visco fuse but I dont think that you will use this amount fuse

Hello guys!

I'm watching this for some time now and finally decided to post something that might be of some interest for you. Especially those building your own Fuse Machines. I made mine by idea picked elsewhere on Net and added DC motor to drive mechanics. And so far it works nearly perfect....
You can see two images by clicking these links:

If you have any questons, I'm opened for talk...
