Hello Tdpyro!

Happy to hear positive riwiew from the author. We could call this "in line" version of the machine which really makes threading much simpler and thus the life of a Pyro easier. Not to mention there are practically no powder spills. I checked that Ebay link someone provided here and saw well known wooden design which is much larger than compact machine (H=30cm, L=25cm, W=25cm) I made. As for NC application and drying, it's done in a separate process...you can see more details by clicking the following link:

Steve, it is not a good idea to directly post e-mail addresses, unless they want to get a lot of viagra and gold jewelery related mails!

Hi everybody.
This topic is verry coool and it can help pyros who cant find visco.
I am impresed by the design of tdpyro's visco machine but i cant understand how the string is aplied around the black powder, so can someone explain the first step of the machine how the fuse is made pls?
Best wishes Svarc

@svarc:

There is a funnel, where the BP is applied.

The yarns are canalized into the funnels bore and cover the whole inner wall. This way a closed tube is formed - not very stable but tight enough to hold the BP inside.

One may say, there is no string applied to the BP, but sone BP is put into the string (tube).

The second layer is wound in opposite direction to stabilize this tube.

Thanks newtoolsmith.
I think i understand now. So for 1,5mm fuse if the strings are 0,3mm thick you must have 12 strings to cover the inner wall of the tube where the fuse is wound for the machine to work and to produce fuse. Right?
Thanks again and Happy New Year to all.

[newtoolsmith]

@svarc,

right!

the twelve strings of 0,3mm each will form a closed tube of aproximately 1,5mm outer and 0,85mm inner diameter.

merry christmas and a happy new year - for the last one we are specialists, arent we?

Thanks again.
Where can i find some pics or videos of visco maschines? Npt the ones in this forum.
Unce more Happy New Year and let god, as every year, this one too, keep our hands and legs tight to our bodies.
Just jocking.
I wish every bodies in this forum have a great time and be safe.

Dude, we all really wanna see a video of that machine in action. I'm trying to build one myself and am kinda going by TD's design, at least in the vertical sense. I really would like to see it in motion though, especially one that makes perfect fuse like that!

[wyattp4007]

Oh and one more thing, if you need somewhere to host it I can do that for you, just send it to me and I'll get it up on my Google page, otherwise just host it through Google Video or something. Just try and get us one!

Heres a few photos of a visco machine I've been building, it will hopefully be finished in the next few weeks.

http://s11.photobuck.....Visco machine

A feature I am including in the design of the machine is a draw rate regulation system. This will keep the draw rate of the fuse through the machine constant with respect to the rotation rates of the spindle plates, regardless of the increasing diameter of the collection spool. This is just a simple friction clutch on the drive shaft of the collection spool.


The most difficult task I foresee is determining the correct draw and spin rates in relation to each other. Can anyone that has built one of these machines advise on a starting point?
