Pardon my poking in my 2 cents, ( Er....Pence? ) but I would think that you would be much more successsful in making small diameter black match and then coating that with N/C Laquer, then whatever suitable finish you like. Seems a bit easier than trying to find Hollow String, though I'm sure it exists.
Has anyone tried to make "Homemade Visco" by injecting BP paste into a hollow-cored string using a hobby syringe? And if so, was it successful? (burn rate etc.)
I was thinking of giving this a go but can't find any hollow cored string!

I cant make salutes either, because the fuse hole is too big. Maybe FP will be better for the job.
I WANT VISCO! *cries*

It is also not unlike how real visco is made, they just spin it with finer threads and more of them in parallel for each layer. I've got some pictures of a visco machine, I've been slowly working on making my own. Unlike some kinds of blasting fuse the casing isn't braided, it is just wrapped, I had a friend in the US do an autopsy of a piece of visco to confirm its internal construction.
The core thread(s) are moistened and pulled damp through a hopper of /dry/ fuse composition powder is almost all brands, very few apply it as a slurry. I found that rather suprising! Next a layer of up to 12 parallel fine threads are spun over the powder train and core threads. Next another layer of thicker yarns are spun in the opposite direction. If the fuse is to be lacquered it is then run through a bath of coloured lacquer and dried in a heated tunnel before being spooled up ready for sale.
Wrapping blackmatch by hand is a royal pain, I've done it a few times, and I'd never bother again. Chinese cracker fuse is easier to make and performs about the same if made well. The paper coating offers some moisture protection and it can be lacquered to become fully water-proof. You have to be cautious though, chinese fuse can skip, jump, and holdfire if the powder train isn't done properly. I 've used a paste of meal and NC lacquer in chinese fuse, which works great, but means you have to wrap it up quickly before it dries, and you usually get the paste all over your fingers. The acetone isn't great for your skin, and the dried paste is very hard to get off compared to straight meal dust.

One question though, I was confused when you spoke of 'parallel' threads being spun? Surely if the threads are spun around the core they are nolonger parallel with it?

Take a look at the picture I posted the URL to, it shows the layers peeled off. Relative to the core yarns the outer casing yarns are orthorgonal (but obviously coil around in the Z direction), and are mutually parallel to each other.

Great! Is it any good? Proper visco, not some other type? Is your 'contact' willing to sell to any of us? I would be extremely happy to buy some, how much did he sell it for you anyway?
yeah i have got it sorry for not speaking
15m for ??
Bagsie I get the next sale from him!
BTW peeps: I tried my new blackmatch, and it burns through a 4.5mm hole However for some reason I'm still getting beads of moulten BP rolling around over the fuse, even though my BP burning on its own doesnt do that any more (after a thorough milling).
"Visco?, every little helps!"

Expensive but if you have no other source then some people are willing to pay anything.. unfortunately some people will take advantage of this fact.
Before anyone gets upset, the previous comment was not aimed at anyone in particular in the forum but it is a general fact.
Personaly if I had access to something that others were having a problem getting I would try and assist without bumping up the price for a tidy profit as I am not in this to make money.
In some cases it makes sense if someone has built up a relationship with a supplier, why have it spoiled by requests from a load of other people as a supplier may clamp down on who he supplies all together.

* * * * * sells visco for ?5/meter, and a2wpyro didnt buy from * * * * *
?5/Meter is an insane ripoff, its unbelievable. With any luck whoever a2wpyro bought it off isnt charging that much. Lets just be patient and wait for his reply.

My thoughts on this matter are that the more expensive the fuse is, the less people want to use it, so the more unsafe the hobby becomes - ie at say ?10 per meter for example, you dont want to use much of it on just one device, naturally. This gives you a shorter delay and therefore a larger risk...
