110mm Beraq Shell on whistle rocket


VikingPyrotechnics

Recommended Posts

Hi guys,

 

here is a 110mm Beraqshell on a 1lb whistle rocket.

The Beraqs however, were not timed the traditional way.

I have used here for Bickford Timefuse.

I'm still on some tests off the beraqs to time the traditional way.

Quite a challenge. :D

excellent work my friend!! well done!..

 

By the way, there is nothing wrong with the use of timefuse. Slurry delay is quite tricky, but if you like the challenge go for it.

 

thanks for sharing!

Thank you Fred.

 

I like the way how the Maltese do it.

And I like challenges. This is what makes the hobby so interesting. :D

Very good results, despite the "non-traditional" means, which does not really count if it can be done like that with bickford. Really nice!

My understanding was that the slurrey method on Maltese Beraq inserts were, when you get going en mass, a lot faster than traditional fusing, while also being able to get accurate timings. When you've got ten or twenty thousand insert salutes to make I'm sure cutting out the steps of measuring, cutting, priming, and sealing the timefuse in some secure way and replacing those steps with just smearing some paste over and in to a hole you made with a special spike saves lots of time.

 

However, while perhaps more laborious per unit, very good effects can be obtained with timefuse, paste, paper and string (or time fuse and glue), as VikingPyro technics has shown. If you need any more evidence, "The Master" TR has taken small timed salutes with timefuse to a refined level on his 3lb charcoal core burners with very nice headers.

 

VikingPyrotechnics, your motors performed very well too, giving you the room for those suspenseful delays. Care to share fuel and core dimensions?

Hi Seymour,

 

TR's rockets are one of the best I've seen so far.

(Dan's rockets are also very nice)

I once tried to imitate his " spiral rockets ". :)

The timing of his crossette star is absolutely fascinating, too.....

Love this guy for his rockets :D

 

The dimensions of my spindle I can tell you later

if I were in my workshop.

You tried? You succeeded! Very nice :)

 

What did you use for salute insert casings?

So, my spindle is 6.5 cm long. Diameter at the lower end

is 9mm. Fuel was 76 KClO4, 23 potassium benzoate, 1 copper oxychloride,

Vaseline 3% dissolved in acetone.

 

Thank you.

The tubes I rolled to 10mm ID. And 14 mm OD.

That is one very true point. I would love to learn how to do it, but very little info seems to be around.

Really enjoy this particular firework, it really showcases the "art" of our craft. Has anyone tried colored flash for patterns? Might have to do some work with these when I get back to the states.

Tr has been testing red and green rings of reports.

While I'm at it vp, did you side fuse the inserts or use " bushings " to top fuse them.

If side fused how thick we're the walls?

Hi Dan,

 

the inserts for the Beraq were side-fused.

There were homemade tubes. 3mm wall thickness.

In the double spiral, the inserts were top-fused,

because they were thin and long tubes.

Thanks vp, I haven't tried side fusing my 10mm tubes yet. It would help to stack them for sure.

How did you fix and seal the fuse, wood/super glue, string, a combo?

 

My tubes are able, I must be :)

I used hot glue for this.

I rolled the tubes, dried, hole punched into it, and then the fuse

glued. Then a cardboard glued to the end of the tube ( with wood glue )

then flash is filled in to the tube , another cardboard glued to the other end of the tube and spiked.

 

Tube ID was 20mm.

The 10mm tubes, I have top-fused.

Lot of work :D

Some pics would worth a thousand words.

Also, what is the top diameter of your spindle? (for 1 lb whistle)?

If it works its not too much work :) it seems we share the same method for the 10mm tubes. I use my 1/4" id tubes (2mm walls) to house the fuse and this fits snug in my 10mm tubes with some help from wood glue.

 

1/4" and 10mm id I've tested with success and need no pointers on filling and closing them its just nice to compare methods, I would side fuse the bigger tubes aswell.

I'm still rolling casings as time alows but I'm a fair way behind you guys ( you saw psyco shell )

Re read it , do you have 10mm Time fuse ? Or am I beating around the bushings :)

No, I have normal Bickford Timefuse. (6mm)

I have thin plastic caps for 10mm tubes.

There then I drill a hole into it, put the Timefuse through and gluing the TF with hot glue.

 

 

But great idea with the 6mm tube in 10mm.

Maybe I'll try that sometimes. :)

Nice rocket VP!

 

Seems like a large shell for a 1lb motor, do you know how much it weighed?

 

Then a cardboard glued to the end of the tube ( with wood glue )

then flash is filled in to the tube , another cardboard glued to the other end of the tube and spiked.

 

Do you do a paste wrap of any sort, or is the spiked on end disk enough to seal it?
