I'll start this thread off with my fireworks from last night.

19mm ID end burner.

3" shell.

Brocade horsetail

4" shell with 'purple' (more like pink??) pistil and a D1 petal that blew blind!

4" shell with silver petal and green pistil that blew blind!

4" mine containing all sorts.

4" brocade shell with a few of the pink/purple stars thrown in too.

Filmed from closer by me, and from farther away by my lovely sister.

Wow! those were all quite excellent! Great job, I especially liked the willow type one. That was great, do you care to share the formula for that one?

All in all a great set a fireworks! You should be proud of those ones!

March 21, 2009

Awesome , good job i did really like the rocket,

it look like you have some titan in the rocket , am i right?

March 21, 2009

Some really nice stuff there, great horsetail!

I liked the purple too, what was the formula?

March 21, 2009

That was a great show, Seymour!

Looks like the family was suitably impressed, too. Good job!

Thank you all for your compliments.

That was by brocade inspired by Dave Buell's Slow Gold formula. However, perhaps due to the Pine charcoal I use for streamer stars, the stars burned fairly fast and did not have that glittering effect I wanted. I added extra Sulfur and some bicarbonate to get it going how I like. All but the Titanium were ball milled for an hour.

Pakeha brocade:

Charcoal 39%

Potassium nitrate 34

Sulfur 12

Titanium 7

Sodium bicarbonate 4

Gum Arabic 4

it look like you have some titan in the rocket , am i right?

You are! 10-30 mesh sponge.

I liked the purple too, what was the formula?

Pakeha purple - Fuchsia

Potassium perchlorate 47

Parlon 14

Strontium carbonate 10

Copper (II) oxide 9

Magnalium (-100 mesh) 8

Charcoal 4

Sulfur 4

Gum Arabic 4

So happy with it ^_^

Another whistle rocket: 19mm ID Whistle Rocket And 15g FP Header

March 23, 2009

Good shells Seymour. Really like the mines with the delayed shells in there. Homemade bees?

Cool rocket and shell you had there PGF.

Props to Zmuro's Whistles also.

Maybe I will find the video of my whistle I shot the other night and forgot to tape the stick on. It was hot glued, for about 1 second!!!

March 23, 2009

Zmuro, that was a very good rocket. What size was the core, and how long was the "delay" segment? The brocade stars were 18mm for the horsetail and 11mm for the final shell. I believe the purple stars were something near 10mm too.

PGF, that rocket and it's header were both very nice! What size were each? What size were the stars? Better pearl is a formula I have not yet tried, but seeing that I will be.

psyco_1322, the Bees were homemade. They were 19mm I with 4mm vent holes and used BP + 5% MgAl (-100 mesh) and 5% Ti (10-30 mesh).

Thanks, the rocket was 20mm ID and 115mm long, core burner. The header was a 2.5" plastic shell, I think the stars were 10mm cut. Still needs a little more flash for a stronger break IMO, even though the effect is pretty nice.

Here are all the measurements you need: http://www.shrani.si/f/U/Pz/4kXrWAa8/whistle-tool-mere.doc

Great job, all of you.

I would like to know more about the insert shells used in Seymour´s bees mine. That effect was really nice and the stars were too. How were these insert shells made?

They were 25mm ID tubes, 100mm long. For simplicity I rammed clay plugs in one end of each, and for the other end I glued a thick card disc (4mm), and then sealed it with masking tape. They were completely filled with 9mm rolled stars( BP + 15% Aluminium- 45µm granular, and bound with 5% Gum Arabic). I also threw in a few nitrate strobes, which I think looked a bit messy and was a mistake.

They were side fused with Chinese timefuse (the quality of which is good, the inaccuracy of the timing was due to laziness whilst cutting them on my part), and burst with about one and a half to two teaspoons of standard 70/30 flash using Indian dark flake.

I see. Quite long these units.

What was the wall thickness and which paper did you choose?

As you are a member of Pyroguide as far as I remember, you could work the rough guidelines into a tutorial, if you want. If you share some more basic information someone else could also do that.

Here is the video of my 4oz whistle rocket that I totally forgot to tape the stick on in all the excitement to shoot it. I hot glued it on and for to add tape. It just hung in the sky spinning around in a circle until the header went off. Made a neat noise. I did use a piece of blue falling leaves fuse to light it though. 9 seconds/inch is really slow for fuse!

Not bad! What did you end up using for the catalyst? Copper oxychloride?

Wall thickness is 3mm. These are tubes from the textile industry that I pick up for free. I'd say the paper quality is low, though I ram perfectly good rockets from them.

I'm not sure that there is really enough to it to necessitate a tutorial. Fill it completely with easy to light, hard stars, pour plenty of flash in the gaps, seal it to prevent the lift lighting it. And you are done!

It certainly worked well even with an in flight abortion of the stick!

No, that was actually a red iron catalyst in sally fuel. The fuel is actually very similar to what Jerry Muth burns in his 3/8" rockets.

I think I missed actually seeing the take off, as I was thinking it was still a little slow, but after watching the video it seemed to be moving pretty good. Still not fast enough though.
