pudidotdk Posted March 24, 2008 Posted March 24, 2008 One thing, Did you roll those tubes? Yes, they are homemade.
Mumbles Posted March 24, 2008 Posted March 24, 2008 Very nice. I couldn't get 4 fountains to burn out that simultaneously if I tried.
cplmac Posted March 25, 2008 Posted March 25, 2008 Excellent work Pudi! I liked the spread on your fountains and that Ti looked real coarse. Hst, good job as well!
TheSidewinder Posted March 25, 2008 Posted March 25, 2008 I'm envious, too! And for the same reason Mumbles gave: Timing. Beautiful fountains. Nice and aparkly. Good job.
hst45 Posted March 27, 2008 Posted March 27, 2008 Here's a 3" ball shell, that on the surface looks o.k., but actually I'm disappointed. It was supposed to be glitter to RED, not just glitter. I used my recently improved paint can star roller to roll D-1 on RSIII cores and the D-1 didn't light the redstar comp. Since D-1 has lots of sulfur and my Redstar III is perchlorate based I made up a relay comp. of KNO3/Charcoal/Redgum to run interference between the comps and pass fire to the cores, but not a one of them lit. Perhaps I need to roll redstar/PRIME/relay/glitter? The wonders of trial and error will ensue. The shell actually broke pretty well, although I cut the fuse a bit long and it was past apogee when it lit.
cplmac Posted March 28, 2008 Posted March 28, 2008 That looked pretty nice, if the red cores had lit it would have been very nice. Maybe throw some silicon into that relay prime? Although mixing in some of the red comp probably would work. Are you sure the stars were completely dry?
hst45 Posted March 29, 2008 Posted March 29, 2008 Thanks. I was in kind of a hurry to get these going, so maybe they weren't completely dry; I thought they were, but they only had a few days to dry so they might have been driven in. I did get the D1 wetter than I liked. My RSIII is Blessers red with an additional 3% SrCO3, by the way.
lnstantkarma Posted March 29, 2008 Posted March 29, 2008 Here's all my tooling and my first 1lb rocket I just made. My tooling isn't amazing because I made it all in my metals class on a lathe that's older than me and my teacher is useless so what I do know I learned myself. My spin stabilized rocket tooling that worksMy untested 1lb rocket tooling and a rocket Closup of my spindles, guess which one I made first?one of my stingersMy first cato It was definitely because the tube was really crappy. I liked this KNO3 this guy sells on ebay and I noticed he sold rocket tubes too. Even though they're spiral wound he said they would work so I got a free sample. Also it could've been because I hand rammed the engine but I thought it was possible to make a 1lb that way. Here are the remainsI learned spiral never works
InRainbows Posted March 29, 2008 Posted March 29, 2008 Instantkarma, your talking about the stuff from Phil's general store. He has his own website, but he sells a lot of stuff on eBay too. About the spiral tubes, people say they have great results, even if spiral wound. This is just based on other people, but maybe something else went wrong. It looked sort of stormy in your vid's, did the tube get wet or damp? I don't get what you mean by rammed by hand. if your saying you compressed the fuel under the rammer with hand pressure, it might not be tight enough.
oskarchem Posted March 29, 2008 Posted March 29, 2008 Nice work, anyway, I am guessing you made the smaller spindle first? And in you pic I see that you have a Pyrocreations ball mill, I have a quesion, how long did the belt that came with it last? Mine lasted 15days... And I didn't overload it..
FrankRizzo Posted March 29, 2008 Posted March 29, 2008 The belt broke because that's a rock tumbler, not a ball mill...no matter what Pyrocreations sells 'em as.
lnstantkarma Posted March 29, 2008 Posted March 29, 2008 Inrainbows: It was windy, the fuel might have been too hot but it works for my stingers and 8oz rockets. And you know, I rammed the fuel with a mallet. I thought I would have a problem because the whole case was bulging after I was done, I don't think you can see that in the picture. Oskarchem: The ball mill works okay. Mine came with two belts and I went through them in about two months, during that time I made about 7lbs of bp I know that because I just had to order more KNO3. So then I ordered these "extra strength" belts from them and I have been running my mill nonstop since rockets use a lot of my bp and so far it hasn't had any problems. It's been about two weeks so I don't know for sure.here's the good belt in case you didn't see it P.S. and I always run mine at the max capacity 3lbs(including the media)
pudidotdk Posted March 29, 2008 Posted March 29, 2008 Instantkarma, those tubes looks like crap for rockets, especially if cored rockets.Also if using standard BP those tubes dont stand a chance no matter how hard you ram them.My suggestion will be to get better tubes, ramming 1 lb. rockets should not be an issue.
oskarchem Posted March 29, 2008 Posted March 29, 2008 Instantkarma, mine came with 2 belts tto, any way I am gluing the second one together ( I have done it before and it holds about 7lbs of BP rolling). I will order some of those extra duty blets.
hst45 Posted March 30, 2008 Posted March 30, 2008 It was definitely because the tube was really crappy. I liked this KNO3 this guy sells on ebay and I noticed he sold rocket tubes too.I don't know why I'm doing this as I have absolutely no chance to make a dime off of it, but just for the sake of keeping the record straight, if you're talking about Phildo's general Store, here's a video of his spiral wound tubes used in a 1 lb. rocket. I too was really skeptical of spiral-wound tubes, and yes, I have had CATO's, but in all honesty I experiment a bunch with my fuel so for all I know I would have blown 1/4" thick parallel wound tubes too. Not that I can attest to this comparison, I'm just saying that I've used them and have had good results. (good,...no one's looking... so Phil, can I get that 12,000 feet of free tubes you promised me.....) KIDDING, FFS!!!!! Really, it works o.k.
ActionTekJackson Posted March 30, 2008 Posted March 30, 2008 Oh yes, finally seems like i've got my BP rockets dialed in. I'm so excited!!!! I know I know... I'm lame ;-) Anyway, here are two 1lb BP rockets the first one was made with corned BP that was intentionally made with different carbon for slower burn rate, did pretty good. The second one is the fastest BP JAP has, which is really fast, and I just wanted to see if the tube/nozzle would hold up to it. I think I'm gonna start using the fast stuff more and putting some bigger headers on. Enjoy! Also, beware falling rockets.... here's a picture of what landed not more than 10' away from me, from the sound this thing made coming down and how far in the ground it stuck this coulda seriously hurt someone.... notice how in the picture the rocket looks like its a 4oz rocket, thats because the other 3" of the casing are stuck in the ground! Eeek...
marks265 Posted March 30, 2008 Posted March 30, 2008 WOW, boomarang pyro That was close huh? Nice rockets when in the air-bad rockets when coming back to owner!
oskarchem Posted March 30, 2008 Posted March 30, 2008 ATJ, there's no reason you sould use that faster BP, I think the slow one will do fine, but your better off asking some one more... knowligable.
justanotherpyro Posted March 31, 2008 Posted March 31, 2008 If the rockets can handle faster BP and not CATO then I think it is better to use it. It gives more lifting thrust than the slower so in theory you can lift a heavier payload to a lower height and prevent arcing.
hst45 Posted April 1, 2008 Posted April 1, 2008 This is one I'd kind of forgotten about, but I've been going through some videos I'd shot a while ago and this came up. I was making a few 2" ball shell headers with various stars, and I was making one in red, and I had one particularly large blue star left over from a previous shell, and for some reason I thought to grab it and put it in the center next to the burst bag. I totally forgot about labeling it, and had no clue when I shot it, but as luck happened I got it on video. It's nothing really special, but I thought that it was a nice surprise when I saw it. Hope you enjoy it too.
qwezxc12 Posted April 1, 2008 Posted April 1, 2008 That is really cool! I hope you feel that imitation is the sincerest form of flattery 'cause I'm totally stealing that idea!
hst45 Posted April 1, 2008 Posted April 1, 2008 Anytime! It was just a one-of moment that happened to turn out. I've always wondered about the very first practitioners of the flame a couple of centuries ago. I can imagine some apprentice in China setting up a display, the fuse might have been black powder rubbed into a silk string, and it started to rain. The apprentice might have thought, "the master fireworks maker has told me that I can't let this fuse get wet. I know, I'll take some of these hollow reeds over here and put them over the fuses to protect them." Imagine the apprentices wonder when he lit the fuse and found that he's invented quickmatch, and advanced the science quite by accident. I'm sure that the very first starmine was a flowerpotted shell that the crowd just happened to love. For me, it's the innovation that's the fun. I could go down to the fireworks store 6 miles away any buy great shells, candles and cakes, but it's the fact the I can do it myself that's the the fun of it. And the BOOM... the BOOM's good too.
