Got back the other day from my holiday in belgium, amazing countryside. Belgium's fireworks are of a much higher standard than that of the french's, I even noticed that the flemish put visco on their fireworks.

Great until I got back, as my sister had left the house in ruin, broken our computer and knocked over my stars and lift powder into a puddle which had formed inside the garage.

I built a bp powder die today following the design Dan Williams has on his site, except I used 2" PVC instead of 3". Its pretty sweet, I should be pressing some BP tomorow if I'm not busy. :)

I havent used my new bp die yet because I had to make another batch of bp before I had the amount I'm going to use in the press, but I did get my star roller working finally! Yay. I rolled some Chrysanthemum of Mystery, but I need to make another batch of it because I ran out and most of the stars arent big enough yet. It was hard at first but once I got them going it wasnt too bad, I'm so happy I finally got the thing to turn at a usable speed. Its not too late yet and I think the bp is done, so I'm gonna go test out that die now.

The internet is finally a luxury I can use again. I was surprised at how little activity I saw happened while I was gone. For some reason I expected pages of missed posts, but got through it all in about 10 minutes. Oh well I guess the 4th got people offline for a while.

 

Interesting totse.com video. I always thought it was pronounce tote-see. Oh well who cares about those communists.

 

Quick question. I recently made a fountain of meal and metal. The metal used was brake dust from work. It is pretty granular and has some rust and oil mixed in, but made some very decent sparks. Anyways my plug was blown out. I think this may be due to 2 causes. Let me explain the fountain though.

 

ID=5/8"

Choke=1/4"

Meal:Metal=50g:5g

plugs: 1/2"-3/4" deep (guesstimate)

 

So I think the metal might create too much slag or my choke may have been too tight. Either way it was the most impressive fountain I've ever made. It had huge sparks about 15-25 feet in the air for ~1 second. Then the plug blew (quite loudly) and it was sending sparks maybe 3 feet in the air.

 

The meal was undermilled btw.

 

Duh, I just realized I forgot to ask the question. Well what do you think the reason for my blown plug may have been?

My guess would be slag.

 

With metal containing fountains I found that using a wider nozzel is needed because the nozzel creates alot of slag depending on the size of the metals. Make your plugs deeper to about 1" and then use a slightly wider nozzel (choke), I'd say to about 3/8".

 

If it works than after a few seconds blows again add plain BP layers every 1.5" or 2" of your fountain. Just a 1/16" layer to get rid of any slag that may have formed. These layers are also a good time to add a different comp.

wow that is EXACTLY what happened to me i posted a video:my fountain i found my nozzle a few feet away filled with slag but it was burnt at the bottom so it may have been a little thin. my meal wan't undermilled

I was wondering if anyone here was interested in ordering paper shell casings and other stuff in bulk from somewhere like supreme pyro and then distributing them in the US. I think this would be a good way since we would basically spread out the large shipping cost so we can all get what we need at a good price.

hmmm... So today I tried to see if a KClO4 (70)/pban (10)/sally (20)/ferric chromate (+1) whistle mix would actually whistle. The mix sort of "makes" a whistle. It is really muffled by the rubber. I am thinking 3-5% would work out much better. Say is xylene capable of thinning pban/der epoxy? At 10% pban this stuff is a bitch to mix... I assum 5% would be 1000X more of a pain in the ass.

Hmmm, i would be more interested if some one where to buy in bulk a large amount of KCL04 and KCL03 say, from hummel croton and resell it, phildo should do it, there are a lot of people on rec. pyro that want him to, maybe i'll make a poll to see what everyone thinks, i'd do it but i don't have the money :( .

I live 10 minutes from hummel. I guess that's my claim to fame. I think that would be great. He could make a lot of money. There is a great demand for oxidisers. Pot. Chlorate on ebay is just so expensive that you could make a fortune.

Holy cow! you have to be one of the luckiest pyros alive. it would be soooo cool if you could get a drum or two of pot. perchlorate and resell it. you could just do it by email, if you just sell oxidisers in small amounts i don't think you would have any problems with anyone, i would sure buy some. :D

Well I'll look into it. I thought they only sold to people with licenses. I'm only 15 so they probably wouldn't sell to me. My brother's 18 so maybe he could buy. My parents probably wouldn't do it for me.

Be careful people, reselling without license should be illegal, at least it's in Germany. And we usually have less restrictions due to less paranoia.

 

Probably because we don't fuck much with moslem countries (less terrorist threats), and meth is close to unknown over here. Means you can buy iodine and res phos, as well as benzaldehyde and nitroethane without *too much* trouble. Our government was wise enough to restrict ephedrine, not iodine and phosphorus. In the USA, next thing the'll do is sell ammonium nitrate at wall mart, but ban diesel! :P

 

*...* meaning it is legal, but you have to make friends with a pharmacist, or mail order from one of the few shops that *do* sell to individuals. A pint of BA costs me over 60 dollars, but it's p.a. (AR) and comes with an analysis of the trace compounds.

(Hey man, this shit is 90 percent cut! - So what, the other 10 percent are 99.999 percent pure!) :ph34r:

Yup, evaporate/boil to dryness. Its really hygroscopic though, so to really get it completely dry your going to have to heat it in a porcelain pan or something for a while. That isn't always necessary though. If you were going to want to make glacial acetic acid though, you would want it as dry as possible.

 

I'm surprised that the whistle match didn't burn fast!

 

For cooling condensers you can just have faucet or hose water running through it or use a pump. Personally i have a little pump that was on a fish tank, i just took off the filters and stuff. Similar to this:

I would recommend getting one that will last though and that you might find other uses for later on (running water jet vacuum aspirator, etc) like this:

This:

Or this:

Personally im thinking of upgrading my system to one of those 12V pumps... You can always control their output with electronics or through a y split with valves.

UPDATE

 

Ahh finally I had the opportiunity to go to harbor freight and got the cheapo 10 dollar pump. It works excellent but I need to get tubing that will have a snugger fit. I already have a vacuum pump that works very well.

Hopefully this is in the right place.

 

I was using wolter's bottle rocket tooling and decided on changing spindle for the smaller 2" casing. I took out the set screw, but getting out the spindle is much harder than just "tapping" it out. Any suggestions for people who have used this before?

Grrrr, how do you get that annoying bar of ads and stuff on the left side of the page on rec. pyro to go away, it's driving me crazy. :angry:
