When I looked up the resistance, it was listed as good. I would think you could use them one time use. If you notice them starting to swell, or become thin, and trust me you will notice this, just change them. With some halogenated hydrocarbons you can actually allow the gloves to dry, and reuse them after they start to swell.

hahah i just tried making a Golden powder rocket and it catoed on me.. Very nice report. Thank you god I decided to use paper...

[DeAdFX]

The color change was not intentional. I think I might of mixed my chemicals poorly or something which might have caused the weird purple/red color at the end. I noticed that my copper tartrate and copper oxide blue's burn with a slight redish flame on the tip. Diluting the compisition with a little Basic copper nitrate helps reduce that issue and also helps with the burn rate. I haved tried burning the basic copper nitrate variant during the night so I don't know how it will affect the color/light output.

 

I think the blue could have been one of these comps... Oh by the way all of these comps are a bitch to ignite with golden powder.. you will need some fairly potent prime. Use a stargun to test your primes first as you will probably have to go through a few stars to get it right(I haven't)

 

NH4ClO4 7

Hexamine 1.5

Copper Oxide 1.5

 

NH4ClO4 6

Cu(II) Tartrate 2

Hexamine 2

 

NH4ClO4 5.5

Hexamine 1.5

Glycine 1.5

CuSO4 1.5

 

 

I kinda wish that there was a cheaper way to make the Golden powder have a better flame. I could try making some with a little bit of sucrose.

You did react very fast to my question. I made the same experience, a lot of CATO´s, nice reports, not one lift off. But I will try it again with other additives like NH4NO3 and charcoal. This comp burns well and not so fast as Golden powder. Maybe I can post a video in a vew hours.

 

No, sorry. It seems that unconfined GP as a slow down mix always burns like BP, but rammed in a rocket...no thrust.

DeAdFx, I've been trying to improve my blues lately, and I've been getting good initial results with your first comp, bound with shellac. It's a modification of "Euters Blue" listed in the Compositions section.

http://www.apcforum.net/forums/index.php?showtopic=625

 

I've noticed that using a relatively large amount of shellac will yield a very hard star that's a royal pain to light, but a smaller amount will yield a slightly crumbly star that takes fire much more easily. I used shellac, not shellac flakes plus Etoh, since that's what I had at hand. In my first test in a 4oz rocket a dozen of the crumbly stars gave a very good bright blue. Very promising.

[DeAdFX]

I haven't tried using shellac flakes and I probably will never until I can find a local source. Does the shellac solution at hardware stores work as a subsitute? I think lowes or something like that might carry a solution for an acceptable price.

[BigBang]

Ok, not fucking cool. Let's get back to approving members like uk rocketry. I volunteer to personally read and approve members. Mumbles, IM me so we can get this started again.

 

I do NOT want to see a naked dude and some whore.

[jacob]

i agree, that was nasty

[Mumbles]

Care to fill me in? It was obviously something I didn't delete.

 

There was another one in the rules section. I fucking opened it in class. Usually they're just a bunch of links, so I didn't think anything of it until I started seeing actual images. Luckily I was sitting in the back.

[ewest]

I think that's the one they're referring to.

[hst45]

DeAdFx, shellac from the hardware store is the stuff I used. Not the white pigment primer like Kilz brand, its called orange shellac, and it's, well, orange. I wetted the comp with an eye dropper and kneaded it in until the desired consistence was achieved. The downside to doing it this way is that I have no quick and easy way to know how much shellac I'm adding, since I don't know the ratio of solids to volatiles in the can. I could of course weigh a sample, evaporate the volatiles, and weigh the remainder, but in this case I used trial and error.

[DeAdFX]

Hmmm Just discovered hex nuts make acceptable improvised ball milling media. The nuts work a lot nicer than coins even though they are hollow. A major disadvantage is that the comp will get stuck in the holes of nuts while milling so you have to shake the jar up every once in awhile. Hmmm 1 step closer to making BP lift .

[Mumbles]

I wouldn't use steel to mill up BP. It has the potential to spark, and will corrode from contact with the KNO3 and sulfur when moisture is present. For individual dry chems it should be fine though.

 

The shellac can should say how much shellac, or at least volatiles percent. You can figure out the shellac concentration from there. I want to say that the commercial stuff is usually 4-10% maybe. The most concentrated stuff is around 42%

I hate not being able to do pyro. I keep being reminded of it and it makes me sad. I smelt something cooking the other day that had a hint of garlic to it and it reminded me of BP smoke. And baked a cake the other day and the smell of the oven reminded me of cooking dextrin. And the fiberglass kit with its MEKP catalyst bottle which wasn't sealed and leaked in the bag. And even the weather. It's autumn here now, the time when everything is clear and still and cool at night and good for pyro - when I did a lot of it most previous years. And I keep seeing things like tubes or aluminium bar and thinking "that tube would have been perfect for a rocket" and "I could have made an awesome set of rocket tooling with that aluminium".

 

Makes me feel weird. If this was by choice it wouldn't be so bad because I could always go back to it. But having a big part of myself forced away is difficult. All the shit in my head is useless now. It'll always be there for me to use in the future (licenced) but I'm not sure I even want to do that anymore.

 

Bah, I'm done for now.

[maximusg]

Yeah that must suck dude

 

you dont want to sell any tooling, now that your on hiatus do you?

[DeAdFX]

Ahhh... I know how you feel. Now that I have school(college) I can't devote much time to pyrotechnics. If I am lucky I can make a sparkler or a fountain on the weekends. Since I am in a dorm I cannot store/manufacture anything :/. I could roll some tubes but its not really worth the trouble.

[Swany]

Same here, I have been up to my ears in applications, studying, more studying, extracurricular stuff, and some more studying.

 

Hope everybody is well.

[asilentbob]

Today was actually the first day that i have been able to do anything pyro in a while.

 

I made 100g of D1 glitter, works pretty well for being mixed very crappily. I'm thinking that ill pump some 1/4" stars with it tonight.

[qwezxc12]

I just got two 6" HDPE mortars from Kastner and I've spent some nights this week building my first 6" shells. *%$^#! they take a crapload of materials...I've gone through almost 3lbs of ballmilled TigerTail just to roll up 200 or so 7/8" stars on colored cores for two shells. Then there's the pistil, the burst, the lift...and I thought 4" shells ate chems up.

 

Is anybody else working on anything? It's been soooo quiet around here.

[Umphrey]

This is getting ridiculous, nearly everytime I visit the forum I am greeted by pornography ads. My family was visiting and I had my 11 year old niece watching me on the computer when I was checking the forum, I click on the newest posts and am greeted by a screen full of porn.

Now most of my relatives are completely ignorant of computers, so they don't understand how it happend. They've accused me of trying to corrupt my niece.

 

There has to be something that can be done about these spambots. Member validation or perhaps a pyro questionnaire would curb this invasion. If requirements to list the constituents of black powder was introduced into the member signup, I think this would seriously prevent any bots from getting in.

 

This would of course depend on just how automated these bots actually are. I've encountered people who manually sign up bots onto forums, if this was the case it might be more difficult to prevent.

[weknowpyro]

I agree about doing the pyro questionaire. Not only would it deter spam bots but it would get rid of a huge influx of k3wls joining the forum, who have no knowledge of pyrotechnics.

Yes, i admit with no embrassment that I was a complete loser in the past and thought i was the best "bomb3r" around and I think most people are like that when they first start the hobby. But when i joined this forum I at least joined with some prior experience and knowledge; although my safety knowledge was lacking greatly.

This is why I also say we should get some sort of system in place.

[Mardec]

Funny how that goes he?

 

At first I was fearless about the most dangerous things.

 

Now I am crapping my pants with relative safe things..

 

 

 

With knowledge comes responsability I gues

[pudidotdk]

Any tricks for getting Red iron oxide shit off the floor? I made a pile of thermite, a quick movement and a smaller part was spilled. I've tried a tape-method, but that works better with small parts.

[asilentbob]

Generally you can tell which threads are spam by the title. Just don't open them.

 

But yes, a test of some sort would be good.

 

On some forum i visited a few months back they had a structual pic of NM, and you had to type its trivial name in a text box to enter. IE.

http://content.answers.com/main/content/wp...tromethane2.png =?

Answer = nitromethane

 

Perhaps we could do something like:

"Whats the "standard" composition for BP?"

KNO3=?

C=?

S=?

 

Thats three variables that they have to get right.

 

Then maybe some common sense multiple choice safety questions.

[hst45]

This wouldn't help with the spammers, but to cut down on the K3WL's, how about this question:

 

"Dude, whatz yer favorite X-plosive?"

 

And when they answer "AP". immediately transfer them to Totse
