Somebody know what fuses uses in this display?

[kleberrios]

Hi guys. The fuses have several speeds, Somebody know how to make them? And these bombs that look like worms kkk

Those are also often called Mascaletta. From the few parts where you see a close up view of parts of it, it looks to be fused totally traditionally. It's just quickmatch with varying amounts string tied in knots around it. The knots temporarily choke off the fire transfer. You can see a fast section with basically no knots other than the transfer points between about 1:00 and 1:30. I don't recall approximately how much delay each knot gives, but it's probably around 0.1 to 0.2 seconds, but that will depend on the quickmatch itself. Also note that each salute is typically suspended off the ground with string or quickmatch and has it's own piece of quickmatch that splices in. If the salute is too close to the timing quickmatch, it can blow it apart and kill the chain. If it's allowed to hit the ground it can throw rocks. Suspended with string is really best.

 

Longer delays can be made with time fuse or spolette buckets.

I'm not going to watch 11 minutes of salutes to give you an answer about fuse speeds! Quick-match (piped match) can be fast OR slow, depending upon how you treat it.

 

FAST lengths are unrestricted. Slower lengths have sections that are constricted with 'ties' of hemp twine, tied tightly around single or double bends of the piped match.

 

It's a 'basic' operation, and well-known among pretty-much ALL competent pyros.

 

(PS... I see that Mumb posted before I did, and he's correct... it's just 'knots')

Ok. I Understand now. Thanks Mumbles

Knots are very difficult, but I've seen some rsrs thanks

"Knots are very difficult, but I've seen some rsrs thanks"

I don't have a clue what "rsrs" are, but really? A GOOD tight clove hitch takes about three seconds to tie, and isn't 'difficult' -- it's EASY.

 

You need to learn that simple pyro skill if you wish to duplicate such effects. It takes only a little practice. I even taught it in my 'Plastic shell class', and a few folks didn't 'get' it, but most (who'd never tied one before) did.

 

I'm not 'chiding' you, so much as trying to encourage you to learn a very basic pyro skill that will reach far into your hobby. Clove hitches (and FAST ones!) are a 'fundamental' in this art. Consider what it takes to tie 200-300 knots on a finale chain. The clove hitch is 'it'. Done well, it goes so fast you can hardly count how many knots you've made.

From some serious experimenting, quick match with one large "rope" core down the middle can be slower very easily by tying knots in binding string, or tying longer knots of many turns. With the paper casing loose it behaves like quick match, with the casing tightly bound to the core it behaves like visco, and burns slowly. This QM is called "Spanish match" in the UK and is the perfect material for timing masclettas.

 

However we failed to get useful results with Chinese QM with either five thin strands or one big rectangular string.

[lloyd]

Arthur, we made a 'double-bend' (sort of a 'bow') and tied both ends. That will restrict the 5-strand match enough to give you some useful delays.
