“Spolette” Is cool name

[Richtee]

But it hardly seems worth the trouble. Here’s a 2” canister. 2 end discs punched for visco. Visco wrapped in wood glue and paper to about .25”. Another end disc added with a “star cut” for the “cannula” the visco is contained in, and wood glue fillet’d around the opening. Easy Peasy.

Of course one splits the visible visco, applies NC lacquer and dips in BP fines/30 mesh.

Building spolette's for real cylinder shells. Is the least troublesome part. How are you going to get the rest of the shell built correctly. If you perceive spolette's as too much work ?

I always use spoolies now! I especially like adding a bit of titanium to the BP I ram in the spolette. You would be surprised how much just a little titanium does!

[Richtee]

I know..mine are small. But very real But that fuse will do a 12” well. You guys work too hard

Work beneath me. I have larger conerns, don’tchaknow.

Using visco or time fuse in smaller shells or inserts is totally fine, though a solid spollete when drilled back allows for more precise timing than visco. It also provides a solid tie-off point for spiking and building a crown while pasting. They also have a much larger surface for taking/passing fire. I'll use time fuse occasionally for single break shells, but for multis I consider the spolette an essential part of the structure. And FWIW I think gluing up fuses takes about the same amount of time as ramming a spolette.

Yeah..good points. I don’t build anything large enough to spike, nor anything more than a small bottom shot for “multi-breaks” so... but at least I don’t have to buy cute little tubes

Yeah, I was going to mention how spoolies help with the spiking, but forgot and then didn't bother to go back and edit my post LOL

I use fast Chinese VSCO covered with aluminum tape Too pass Fire to the center of my 3in round shells. Mine are all rocket headers so the faster the fuse to the easier it is for me to time them with the delay grain of the rocket.

Italians actually use their "Monetti" timefuse for multibreak shells. It makes it very very easy to time and construct their Insert shells, the timefuse is cut to lenght, shoved in a relatively soft passfire tube and tied with string to hold it in place. No glue at all and they still withstand the main break charge.

 

Keep in mind Italian fireworks are basically the origin of multibreak shells and most of their fireworks consist of those.

I use 1/4" timefuse on multibreak shells. I've done it since the 1980s. It's a real time-saver. Many say that to get good timing, spolettes are required. They should tell that to Tom Rebenklau...
