They do use a Perc formula for the 'Fast Visco' Fuses. Sorry I do not know the exact composition

Here is some photos of the machine.
It's not completely finished yet so it isn't looking great, but it works.


Picture three shows how the nitrocellulose application works. The pulley set up is submerged in the tin to the right of the picture, this is shrinking dope , that is found in model shops. I used fabric die in this to give it the green colour.

I will try to get some videos of it soon.

I'm very impressed, having rebuilt too many old motorcyles I appreciate the accuracy of your construction.

Working at high speed as well, so little room for error.

Excellent product too.

Yeah, really nice. How much does it cost to build 1 ?
Will you do a how-to guide to build one ?
Thank You !

Here is what it produces (Viewed under a magnifying glass) :Visco

Did you get round to doing a video of the machine in action?

[pyrotechnist]

Any news on a vid yet of this machine in action?

[Pretty green flames]

Anyone know how do you control the diameter of the finished fuse.

(I have made a motor to be mounted on to it, you may be able to see the white cog at the top of the drive shaft, but havent tried using it yet)

Nice construction.

Just watch out for sparks from the motor! Also any static build up from the moving parts.

I spent the last weeks on building a visco machine too and found a little problem:

The NC-paint wont dry in the short time through the machine.

Since I am an mechanical engineer, the machine has become quite compact with relatively short ways. So, using a production speed of 2cm/s the visco has only two minutes before getting automatically spooled.

Has anybode tried to use a hair dryer to blow away the solvent? Quite dangerous and once ignited the whole machine will burn instantly. But it is the only solution I see.

By the way, the machine is electrified by using an old Accu-Drill and a Computer-Powersource. Each Yarn spool carries 1000m and the only thing you have to do is to fill BP and NC-Paint in and switch the machine on. Its overall Dimensions are round 30*30*110cm.

If I find out how to do, a mpg and some jpg's will follow.

Your machine sounds impressive.

Just a thought, if drying speed is a problem, why not try a lower boiling point solvent for the NC and an unheated (compressed?) air supply?

Wow, all those machines seem mighty impressive, though I can't get a lot of the links to work . I love building stuff, and I want to build a visco machine (I like having multiple projects at once, so if I get frustrated on one, I can cool off by working on the other, thereby greatly reducing the number of holes in the wall I will have to fix) but I want to know where you got the design/plans/directions from, or if you figured it out on your own?

I would also apprecitiate if you could tell me of any websites, books, etc. that you used.

Eclectically yours,

P.S. It's snowing...I love the snow...la-dee-dee-da...time to make snow man with banger inside head...

Hello guys!

I made my Fuse Machine by consulting TdPyro images....construction is generally the same with addition of a 24V DC motor which rotates discs and collecting drum. So far it works OK producing decent and reliable fuse. You can see images I posted on other Pyro Forum by clicking the following link:

p.s. Don't ask for blueprints or drawings as I have none of them...

[tdpyro]

Hey guys,

Sorry I havent replied to some of your questions and that the pictures of the visco machine have gone offline. I havent been doing pyro for a while now but im started to get back into it.

Blaf, Nice work on your visco machine, its turned out great, its good to see that you have used the similar vertical design like mine, it makes treading quite a bit simplier.

If anyone still wants the pictures or a vid of the machine in action I would be happy to upload some, I just dont have a webspace anymore.

RE: Drying. An infra-red lamp possibly with forced air? Or simply make the finished, laquered fuse run a longer length to dry so it won't stick together on the coil.

Just thought I would mention this... somone is selling a visco making machine on ebay:

Visco Machine

I dont really know whether it would work, but it looks impressive.

(oops somones already spotted this and posted the link in a different topic, sorry)
