Well here is the videos of the Sun and planets 5 inch shell, if you look on vid 2 the lovely camera lady did just what i wanted and caught the suprise in the lift Oh by the way this was lifted with 125g lift. Mortar was buried in the ground and we used spun fiber tube.

Select 'Videos' - Download 'sunandplanetscam1.wmv' for cam 1 or 'sunandplanetscam2.wmv' for cam 2

Will add the other vid when i get the file off Wazi, or Wazi if you want edit this post and add it thats cool.

Hope you all like the shell, its good to have a multibreak shell under my belt now

Check out these lift charge stills! Cant beat magnesium reds

Fantastic Karl

That shell was certainly the highlight of my evening. Its been a top 2005, we have a great crew around us and i'm looking forward to 2006.

(Red lift charges come out real nice when I once again have the camera on the wrong settings )

[karlfoxman]

Right guys, time to discuss this shell. How do you all think it performed? Timings i thought were on cue, but the break pattern on the first break was not how i wanted. This is either due to a spiking not enough, inserts not packed well enough or break charge not strong enough. Please look at the vids and give any feedback you can.

Thanks

Going from left to right. There is a 2" Ti salute shell. It contains about 10g of flash powder, -60+100 Ti flakes, and BP covered rice hulls to fill in the rest of the space. That thing is going to be a nice way to ring in the new year.

Then we have a 3" canister of goodies. There are 8 1" shells with 1g of flash in each of them. There are also 30 1" pieces of chinese visco for use as a flying fish type of thing. The shell is off center spiked and beautiful if I do say so myself. The string isn't messed up, it is the fuse hole that is not in the middle of the disk. There are 16 verticals and 9 horizonal spikes. The burst is BP on rice hulls. I am officially in love with off center spiking.

On the right we have a 4" crown brocade. There are slow gold stars(from passfire). The burst in BP on rice hulls with .5g of flash booster. There is a "snowball sparker" comet(by Davis) on top.

Mmmmmmmmm, check out that sexy off center spike. By the way, it isn't the string that is messed up, it is the fact that I had to hand drill the fuse hole in the disk, and I didn't get it right in the middle. That is why the fuse isn't in the exact middle of the string.


Lets just say the shells look better in picture than they preformed. My lift crapped out on me. Nothing got more that 10 feet in the air. It is hard to understand it. I tried using SGRS, so perhaps that was it. It was -4+16 mesh which has worked for me just fine in the past. Burning small samples of lift before attaching to the shell showed nothing unusual. I will have to experiment with it more when I get home. Looks like I am using dextrin again. It's a shame, it binds those granules ROCK hard. The shells would have been beautiful, ya know, if they were in the air. I think I had the timing just right too. Now I am just going to be curious about this until I get a chance to try them again.



That sun and planets looks beauiful by the way. I really like the way it was timed. It seems like the inserts bursted relativly symetrical.

there I got the clip on the net 3inchshell.mpg and I have a 3 inch canister shell that I will probably set off tomorow when my bp on rice puffs dry

Hi Mumbles

I am sure your shells would have looked fab in the air.
How much dextrin are you using? I use 7% to bind for corned lift.

Nice shell, your timings are spot on. Post the can shell once youve launched it, i am sure everyone would like a look.
ps. got any construction piccies?

[completebeginner]

no pics my camera is dead at the moment but ill post the video tomorow

8" spherical shell shooten up successfuly!

On 31st of December I tested my 8" shell with success. The effect was:

"Golden wave to bright red with green to red pistil"

Lifted with 200g of coarse grained Blackpowder it reached about 200m and exploded after a delay of 4 seconds. I?d uploaded the video on infernolabs, but the site doesn?t starts

Thats a damn impressive shell sprengman, what can I say but - well done! What burst charge do you use? Do you form your own hemispheres?
Keep up the good work and keep the video clips coming.

[completebeginner]

I just set off my canister shell it worked magnificently but not all of the stars ignited and the delay was a bit long I would post a clip but my friend screwed up on the filming

[chemicalwazi]

Well done Sprengman that shell is fantastic! Know wonder everyone is cheering.

[paul]

WTF isn?t there sound, Mr. Sprengman?

The burst looks very powerful, but many stars seemed to be crushed from the break or something. Would like to have a longer version of that video!

[Sprengman]

@JamesH : The burst is simply blackpowder on corn cob without any Flash or whistle mix. I?d formed the hemispheres in a milled wooden form.

@paul: There is sound in the Video. I don?t know why you didn?t her it. Send me your E-Mail and I will try to send you a larger version. You?re right, many Stars had been crushed from the burst but I don?t know what to do with this damn Stars. The core of the outer Stars was:

55 Strontiumnitrate
28 Magnesium
10 PVC
7 Red Gum

On this I rolled a hot prime and cooked Chrysanthemum 8 (Shimizu). Although I rolled with a small amount of water an very thin layers some of the stars split of down on the core.
Last year I shoot a 6" Golden wave to red with the same problem. This sucks.
