Umphrey Posted June 15, 2007 Posted June 15, 2007 Thanks for the camera advice, it really helped. After fiddling with the settings and distance, I'm finally getting acceptable photos. Pine charcoal test photo:http://img258.imageshack.us/img258/6277/pinecharcoalyh7.th.jpg My camera seems incapable of taking pictures at night, I've tried taking video of a few of my shells, but everytime it comes out as just a blurr. My camera model is Sipix SC-3300. Any advice on how to configure this one, or on a new digital camera better suited to filming pyrotechnics, would be greatly appreciated.
Tweetybird88 Posted June 15, 2007 Posted June 15, 2007 Just a quick question: For shipping an oxidiser (say potassium perchlorate) by usps, what do you need to do? Is it just get the orm-d sticker and surface transportation only sticker or do I have to do a declaration of dangerous goods thing. I tried using the usps website but I couldnt make any sense of it. Also anyone know of any good youtube videos of pyro?Here are some I like a lot. http://www.youtube.com/watch?v=PC1pVuJe4jI...related&search=
jacob Posted June 15, 2007 Posted June 15, 2007 From what i understand for shipping class 5.1 Oxidizing substances (like potassium perchlorate) by surface transportation you have to ship it in no bigger then 1lb primary receptacles, you have to mark the box with orm-d and ''Surface Mail Only'' on the address side and Each box may not exceed a total gross weight of 25 pounds. keep in mind i don't know everything.
Tweetybird88 Posted June 15, 2007 Posted June 15, 2007 That's what I thought, but do I have to fll out any forms or anything like that?
jacob Posted June 16, 2007 Posted June 16, 2007 only if your shipping it by air. oh and you can't ship it internationally. do a search for ''hazmat'' on the usps website, that should help.
Mumbles Posted June 17, 2007 Posted June 17, 2007 No forms. I have a fair bit of experience in shipping stuff. You need physical addresses, not PO boxes. It must have a label stating the contents by the proper shipping name, UN number, and hazard class. The primary receptical can be no larger than 1 kilogram. It must be contained in a secondary recptical. More than one primary receptical can be held in each secondary receptical. The total net weight of the box cannot be more than 25lbs. It has to be packed solidly with some filler like newspaper, or packing peanuts. Typically my primary receptical is a plastic bag, and the secondary is a tyvex flat rate envelope. The tyvex envelopes are free on the USPS site. Some other people use a box within a box. Search for a document called "Pub 52" It is the thing you will want to look at. They might look at you kinda weird at the post office, but they can't deny it.
mormanman Posted June 18, 2007 Posted June 18, 2007 Um I asked about this before but not the same question so here it is.Why does one need a lathe to make wooden rocket tool could I not carve and drill and glue some wooden dowels?Thanks
jacob Posted June 18, 2007 Posted June 18, 2007 Heh heh, i can just see you widdling down a set of rocket tools, however wood is a awful material for that, it's britle, porous and hard to work with, a tool made by hand will surley make poor rockets. but wood is cheep so it won't be a big loss if it fails.
pudidotdk Posted June 18, 2007 Posted June 18, 2007 If the right kind of wood is used (a hard one that is) I guess it would be able to make some descent rockets. I recall a tutorial on passfire on how to make a wooden stinger missile kit.

Umphrey Posted June 18, 2007 Posted June 18, 2007 mormanman:Why does one need a lathe to make wooden rocket tool could I not carve and drill and glue some wooden dowels? Wooden rocket tooling, regardless of how it is made, is weak, porous, fragile, and difficult to extract. Moreover, how do you plan to drill a perfectly concentric hole, and how do you plan to carve a straight and tapered spindle? If either of these if off, the tooling will jam together and be impossible to seperate without ruining it. The forces needed to press a rocket will crush and deform the hardest of woods, if you're ramming it you'll most likely split the dowel rod or use insufficent force which will fail to consolidate the black powder. With atleast a wood lathe, cheap and disposable rocket tooling could conceivably be made. Trying to do it by hand, unless you are a master carver, is essentially impossible. You'd be better off just ramming rockets with a dowel rod and drilling a core, this will atleast give you a functional rocket without too much hassle. It is better to drill it out with a hand drill, if you must use an electric drill do it very slowly so the friction cannot build up. Regardless, you should be wearing protective gear.
pudidotdk Posted June 18, 2007 Posted June 18, 2007 Well some of the tooling COULD be made out of wood, such as rammers and base, however the spindle would need to be brass or aluminium.
mormanman Posted June 19, 2007 Posted June 19, 2007 Ok guys thanks alot for ruining my idea (just kidding).Right now I'm looking at the UNIVERSAL ROCKET KITIf you want a rocket kit that does it all, here it is. Steve Laduke perfected the universal rocket kit. The universal rocket is one rocket kit that fills the role of 4 different kits. With this kit you can produce red strobes rockets, blue strobes rockets, long winded screamer rockets, and conventional black powder rockets. All you need to do is use a different formula and you get a different rocket. It's just that simple. The kit comes with a stainless steel spindle mounted on a square aluminum base, 3 rammers, puller, and Steve Laduke's formulas and instructions to make all four rockets. Note: Strobe rockets and long winded screamer rockets must be pressed, NEVER rammed. Product Stock# WT Price 1 # Universal Rocket Kit 168-1 2 $91.00 2 # Universal Rocket Kit 168-2 2 $95.00 3 # Universal Rocket Kit 168-3 2 $93.00 4 # Universal Rocket Kit 168-4 2 $110.00 So can anyone tell me about the difference between the numbers, like what the numbers mean?To break down the question b/c it might be confusing. What is the difference between 1 and 2, then 2 to 3, then 3 to 4 and so on? Thanks for all the help guys.
qwezxc12 Posted June 19, 2007 Posted June 19, 2007 I'm sure they're based on size...1/2lb., 1lb., 3lb., 6lb. etc...
mormanman Posted June 19, 2007 Posted June 19, 2007 I'm sure they're based on size...1/2lb., 1lb., 3lb., 6lb. etc...Is that just a guess its fine if it is but which would u recomend one investing in. EDIT++++Um I got a question its pretty simple so here.I keep hearing drill the core. Does that mean to drill the nozle and thats it or drill to the plug? And again thanks.
Swany Posted June 19, 2007 Posted June 19, 2007 Hello y'all. Figured I'd check in, right now I am at a university for a state program and I am working in a organic chemistry lab with graduate students, and it is awsome. Jars of sodium metal, today we used lithium powder, solvents on tap, a 5lb jar of iodine that is 2 feet from my desk, stuff like that. We have a sound system that plays tunes while we do our stuff, everyone I work with is very neat. Mom was happy I was coming to this program as I wouldnt be home to burn/gas/blow/irradiate the house, and figured this would be more safe. Ehh, my first reaction used Br2, PBr3, and P2O5 all in one pot. SO yeh. Stay safe!

asilentbob Posted June 19, 2007 Posted June 19, 2007 Swany, I'm so freaking jealous as you can likely imagine!
weknowpyro Posted June 19, 2007 Posted June 19, 2007 Well, I literally just had a once in a life time experience. There was lightening storm and I was filming from my kitchen. Then the lightening literally hit right in my garden 18 meters away. I can tell you that it was the loudest bang I have heard.Stills from the video is kind of rubbish.
mormanman Posted June 19, 2007 Posted June 19, 2007 Flip thats crazy your lucky and can some help with the question I left a while ago.
crazyboy25 Posted June 19, 2007 Posted June 19, 2007 WOW nice what does it look like where the lightning hit? and mormanman correct me if im wrong guys but you dont need to drill a core if you have rocket tooling if you dont drilling the core means to bore or drill a hole in your rocket through the nozzle (if it has one) and a good way into your fuel creating a core which ignites more fuel in a shorter amount of time.
mormanman Posted June 20, 2007 Posted June 20, 2007 Alright thanks for clearing that up for me crazyboy25
weknowpyro Posted June 20, 2007 Posted June 20, 2007 Its quite weird I was searching for ages last night to find some sort of mark on the ground or on a tree but theres nothing. I expect it was because electrons moved upwards to meet the electrons that were coming downwards, so they met mid air leaving little noticable trace.
optimus Posted June 20, 2007 Posted June 20, 2007 Stills from the video is kind of rubbish. Any chance you could upload the video itself - that looks cool! I was once zapped by a tap just after being forced inside by my GF while watching a storm pass over. Didn't knock me out, but it did scare the bejesus out of me!
