crazyboy25 Posted January 29, 2008 Share Posted January 29, 2008 I have been browsing sciencemadness lately and I have seem a lot of references to "The Hive" what is this referring to? Is it an archive? Link to comment Share on other sites More sharing options...
Mumbles Posted January 29, 2008 Share Posted January 29, 2008 The Hive is a now extinct forum for the discussion of psychotropic substances (drugs). It disappeared around three years or so I believe. It was run my a guy named "Rhodium", of whom no one has heard from. Most of the archives have not been released. The hosting company of whom the forum was hosted on changed posessions, and the new owners were not exactly excited about it, and thus closed it. http://en.wikipedia.org/wiki/The_Hive_(website) You will notice that right about the time the hive went down, Science madness enjoyed the start of the influx of the members "for theory purposes only" wanting to know how to make 3,4,5-trimethoxybenzaldehyde, diethylamine, various forms of nitrostyrenes, and the like started showing up.

bmarley5780 Posted January 30, 2008 Share Posted January 30, 2008 I made some white stars from KNO3, S, C and wow they are awsome!!! Very bright. Link to comment Share on other sites More sharing options...
mormanman Posted January 30, 2008 Share Posted January 30, 2008 I am in a pickle. I don't have a ball mill really. The stupid piece of junk won't run. I changed the pully b/c it was worn out and now it won't turn the barrel at 2.5 lbs. It is the Harbor Freight dual drum 6lbs tumbler. If anyone has any suggestions I'm willing to try them all. I have nothing better to do but read pyro stuff like Mumbles PM-ed me about. Link to comment Share on other sites More sharing options...
Mumbles Posted January 30, 2008 Share Posted January 30, 2008 Not meaning to add more to worry about, but if your jars are only weighing in a 2.5lbs, it is nowhere near charged enough. 100 50 cal lead balls weigh around 1200g, plus 200g of BP, plus say 300g for the jar assembly each. That is like 4lbs per jar, and 100 lead balls don't even properly fill it. Even if you're talking ceramic, one of the lighter milling materials, the total mass should still be up in the vicinity of 5lbs. Perhaps try running the mill with only one jar on it at a time. One thing I have found is that the rock tumblers don't have enough torque to get the jars going at first. So start the mill with no jars on and get the drive rods spinning, then add the jars. It will probably work then. Link to comment Share on other sites More sharing options...
mormanman Posted January 30, 2008 Share Posted January 30, 2008 Thanks Mumbles, but heres the thing. I do that word for word and it worked fine for about 6 months after I fixed the first time. The only thing I can think of is that I lost the bushing things on the rods and the rods have way to much friction but I grease them all the time and its not working.

oskarchem Posted January 30, 2008 Share Posted January 30, 2008 Hey, guys in June it is my step father's 60th birthday, and of course, I will be making fireworks! . Right so anyway here is my idea: Making a Fan rack of 2" mortars and firing 2" double break canisters (and 1 break canisters), I am thinking of 2 racks of 5 mortars each... This will be a big party, like tons of my familie's friends and all of that so evry thing has to go well, I know the party is in june, but as all of you guys know to make a pyro show you need lots of preparation. I guess that TT, C6 stars are nice, but if I make 10 shells with that it will get pretty boaring, So I think to make some color changes and all of that. If you have anythings to add that would make a nice efect please share it with me, so I could figure out how much time I need to make them... I guess I'm gonna start making some TT shells this weekend and order some chemicals from KeteN' some Barium Chlorate! Just love the green colour, and some copper oxide to make some blue stars.

Try rolling some TT stars around White stars. The comp for both is really easy and the white is pretty cool. I still need help with my ball mill.

jacob Posted January 30, 2008 Share Posted January 30, 2008 Good grief mormanman, I'm geting pretty sick and tired of your mill breaking down all the time, do yourself a favor and build a real one, all you really need is a 1/2 or larger electric motor, a few pulleys, pillow blocks and casters, and some scrap wood.honestly, it's not that hard and you'll be glad you did.

Bonny Posted January 30, 2008 Share Posted January 30, 2008 I only have a 1/15HP motor and my ballmill has been chuggin' away on batches up to 1kg + media for a few years now. Link to comment Share on other sites More sharing options...
bmarley5780 Posted January 31, 2008 Share Posted January 31, 2008 I have a 1/3 hp dayton motor. No problems at all. JUST DO IT Link to comment Share on other sites More sharing options...
mormanman Posted January 31, 2008 Share Posted January 31, 2008 Also, I can't find plumming or pillow blocks in Arlington. I'll try to figure something out but it will take a long time. Link to comment Share on other sites More sharing options...
qwezxc12 Posted January 31, 2008 Share Posted January 31, 2008 mormanman,Both Grainger and McMaster-Carr sell 5/8" drive shaft bar, pillow-block bearings, pulleys, belts, and rubber hose online...pretty much anything you might need for a mill. I bought nearly all of the above for my mill at McMaster-Carr: pics Link to comment Share on other sites More sharing options...
oskarchem Posted January 31, 2008 Share Posted January 31, 2008 Yeah, tomorrow, I am going to the gun shop to buy some lead shots for rolling stars, and then order the chems then get a passfire membership, and finally start making the shells and my fan rack. I was also thinking of maybe making a 4" Shell of shells with 1 3/4" shells inside. Anyone would have some info on that? Thanks Link to comment Share on other sites More sharing options...
tentacles Posted January 31, 2008 Share Posted January 31, 2008 mormanman: Any Tractor Supply Co location will have drive shafts, pillow blocks, pulley sheaves and all. Or any other place that sells farming equipment parts. Prices will probably be fairly good as well, farmers are generally a thrifty lot. You can also look in the yellow pages under "bearings", these suppliers will have all you need as well. Link to comment Share on other sites More sharing options...
mormanman Posted January 31, 2008 Share Posted January 31, 2008 Ok, I'll look on all the places. And Oskarchem why do you need lead shot for rolling stars? Link to comment Share on other sites More sharing options...
crazyboy25 Posted January 31, 2008 Share Posted January 31, 2008 Are you kidding? You have been here for seven more months then him and you dont know why you need lead shot to roll stars? It is used as a star core. Oskarchem: I think 4" is a little small for a shell of shells try making a nice 4" shell before moving on to inserts.

Bonny Posted January 31, 2008 Share Posted January 31, 2008 Although small, I think a 4" shell of shells shouldn't be too difficult. Maybe using smaller insert shells than 1-3/4" in a 4" though. I once used 1" cylinder shells as inserts in a 3" cylinder shell and they worked OK. Link to comment Share on other sites More sharing options...
Gottagotomoz Posted February 1, 2008 Share Posted February 1, 2008 When rolling my stars I never have used lead shot? Well, lead shot isn't the only thing that can be used as a core. Lead shot is commonly used, since it's a heavy core, and easy to roll. I've heard of other seeds being used as well. Mumbles also suggested using Acini De Pepe pasta. I bought a box, but I haven't gotten around to trying it out yet. Some people even use small pumped stars as cores. Link to comment Share on other sites More sharing options...
Mumbles Posted February 1, 2008 Share Posted February 1, 2008 Yeah, I'd say that 1 3/4" is too big for 4" shells. About the smallest you can go is 5" for 1 3/4". Just think about it. You can only fit 2 1 3/4" shells across in a shell (2x 1.75 = 3.5"). You need at least 4 shells to have room for burst. For 4", this is 1.44", so maybe start from a 1 3/8" base? Or you could make a more traditional one with 6 or 7 arround in a ring. This is 1" and 7/8" respectively starting diameters approximatly. But yes, you need to be able to make functioning 4" shells before trying inserts and stuff. Link to comment Share on other sites More sharing options...
bmarley5780 Posted February 1, 2008 Share Posted February 1, 2008 I tried the nitrate flash comp KNO3- 5S- 3Al-2 Didn't rupture either of the end plugs, but it shot the fuse out... Turned into a fountain of sorts. Still have a lil comp left. I was wondering if if can make a star out of this if I add some Dex? And 50/50 water/alcohol for the solvent? I thought I read that when water mixes with the Al. it has a chemical reaction and turns the Al. to something else. Oxidizes it?-Sorry, my chemical action and reaction knowledge is limited to laymens... -Joe Link to comment Share on other sites More sharing options...

Using pasta as a core might not be a good idea because the pasta will soak up moisture, either before or after rolling is complete, and probably crack the stars as the expanded pasta contracts upon drying. I always used mustard seeds without trouble... Oh yeah, and hello again. Link to comment Share on other sites More sharing options...
