you dont need to grind the kno3 too fine, or grind it all all, its the purity you need to make sure is adequate - say 96% minimum. Just make rcandy via the cooking method, its easier and saves a lot of hassle, it also produces more thrust per unit volume because of a higher density.
I have a question: When i try to make r candy, after cooking, i let it cool, but when cool, it still remains soft, not hard rock candy, and when I try to ignite it, it ignites for short periods instead of burning equaly. Sorry for my bad english, and thanks.
If moneys can do it why did you know how to use fractional crystallization on the kno3?? i made, tested, and successfully launched my first core burning engine at the ripe old age of....7 ahahahah. I'm 21 now and my core burning engines dont use powdered sugar anymore but carbon black and powdered magnesium. And the rocket caseing is too large vs the motor. Sugar is a soft carbon and is very very low impulse (not much thrust) that rocket would never get off the pad : O
its a giant modle rocket that blows off the nose =/
u should put a explosive charge that does damage either pressure sensitive. or afet it uses up all its fuel like u have for the ejection for the nose atm
how did you bond the kitty litter plugs? would it help maintain stability if i were too very slightly angle the fins giving it a sort of rifleing effect.
Skylighter is way too expensive. You can buy KN03 on Ebay for $2.00 per lbs. For everything else rocket and pyro related I buy from Thunder Valley and discount pyro. Their prices are much lower than skylighter. Skylighter is a rip off! By the way, great video!
I normally use gun powder I steal from my dads bullet shells and it works great, i just have to pack in twice as much as I would with black powder, but it works for me. Nice vid though all the same :)
Hmm...did you buy your nose cone or make it? I lost mine (chute and all) when things went awry in the sky. Don't have hobby shops where I live...is it possible to buy one? make it out of....?
wtf, that diagram was a crapy bear mat doodle and it rilly wasent complicated at all. if its a cross section then there is no need for dashed lines. you are building a rocket, not a missile. you havent added or come up anything new, its all well established modle rocket desine. oh yea, and the diagram was poor... i also give two thumbs down...
sweet thank the lord that atleast 1 person on youtube lives in portland pretty sweet rocket too thanks for the tut and i may take advantage of the combo of that powder and sugar to make fireworks sounds fun!
wat if the nose of the rocket is heavier than the rest? will it still go up?? im not lookign to make somthing that goes really high i just need it to go straight up
You can get KNO3 at fish and gardnaning stores it is used as a fertilizers(you can get a 25 pound bag for 50$ the name of the store is hidrotec i believe)
how do you hammer in the kitty litter plugs in with the fuel in there without it exploding, it's been on my mind for ages or is it just not that volatile?
might not want to use blackpowder for eject chare, i sugest you use flash powder because your rocket is very tall and the flame willl have to travel all the way up your rocket and blow the nose cone off. pack the powder to tight inside the top of the pipe and your rockete will explode.
can u post another rocket description thingy or email it to me to my youtube account. Dont want to give email cause dont want to get spam from other people
that's exactly my purpose of making sparkler stuffs. i don't make them to harm anything or anybody but the fucking cops make it sound like a crime. FUCKING LAWMAKERS!!!!
Skylighter is AWESOME! BUT, be careful; if you buy several things from Skylighter that CAN be used to make other types of explosives or anything like that, they'll red-flag you and won't send you anything for a while, and maybe your online purchases will be watched by some government group. hahaha.
All I buy from skylighter is shell parts and fuse... none of the chemicals ; )
I dont buy chemicals period. All I have to buy is black powder.. no big deal. I rob stars from black box artillery shells. One case is $35 wholesale.. thats 12 boxes each with 6 shells that are color coded with a thread on top. I can use the stars the same size as they already are.. or remake them into larger stars. I can make special effects with other cheap 1.4g works or fish fuse.
what i found that works VERY WELL!!! for fins of a rocket are the thin flexible plastic yellow garage sale signs at home depot.they are tremenduosly strong and light weight. i use them for my rockets and i won the arizona model rocket contest in 07. they are awesome and only like 2 bucks for like a 1 foot by 1 foot sheet.
its funny how a pyros workshop ends up looking like a bakery rather than a mad scientists lab, .lol, containers full of sugar amd corn starch next to the kno3 iron oxide and magnessium powder, coffie grinders cookie sheets wax paper and electric skillet next to the mason jars full of nitrocellulose laquer and acetone..lol..i love pyros
you fill the bottom of the pvc pipe with kitty litter and then use a metal rod to pack it solid, AKA hammer the S out of it. Then you use a drill to make a nozzle. You gotta be careful when u drill because u might knock out too much of the litter. It's a good idea to make it like .5" to .75" thick.
"Kitty litter" is usually bentonite, and is used in cat litter boxes because it soaks up the stuff kitty leaves there. However, it also becomes very hard when it is compacted, and being a mineral, it also handles the heat of the exhaust gasses very well. Most small rocket motors commercially made use it as the nozzle.
that eject charge will probably explode simultaniasly as the fuel ignites:) but hey,live and learn,btw,kno3,i just bought 150kg for aprox. 230 dollar,in Norway tho
you can disolve the grants stump remover in boiling water then let it cool. It crystallizes into a pure potassium nitrate. you then drain the water and let it dry on paper towels for a few days. You get an easily grindable substance, and i mean easily because you can grind it with your bare hands. It's what i had to do because i bought grants stump remover too.
Thanks. Yeah I put the launch for this rocket up, its called 5' homemade rocket explodes. Also I'm working on another one too its the response to this video with the mostly white thumbnail.
Assuming you luck out and get a good starting Kn ratio, this motor will be very progressive, and probably over-pressurize. Also, you need a delay train in your motor. You don't want the ejection charge to go off at motor burnout. Delay the ejjection chg several seconds.
Bad news is that, if your motor works, your airframe will shred. Very quickly. Too much fin span, not enough fin root. Contact me if U want 2 learn.
OK, smart ass. You don't want to learn. OK by me. I'm only a member of the NAR Level 3 Certification Committee. I'm only Launch Director for the largest, most respected TRA prefecture in the world. I only hold three research motor class world altitude records. What do you have? A blown up fincan, and a shredded airframe. Congratulations.
I don't post vids. I fly rockets. Search for AeroPac, Black Rock rockets, Snow Ranch, etc.
Search for "Dave's Q Leap 2." I made both those motors, and developed the staging system used. That little 14 pound package went over 14K on that flight. What have you done?
Ok, in case you haven't noticed, I can't tell any of that about you by your profile or unless you tell me somehow. SO, when you post tips, regardless of how inciteful they may be, you look like a jackass know it all. Apologies for wiseassness. A video might not be a bad idea either, just to back up your claims, this is the internet ya know.
OK, in case you haven't noticed, not everyone that watches vids on here is a 13 year old dumbass kid. Some of us are retired machinists, that like to spend their time accomplishing things. And sometimes, we like to share some of the knowledge that we have acquired over the years.
My first piece of advice is for you to get a long ass roll of speaker wire, and make an electrical ignition system. You want some distance between you and the motor at ignition.
There's my vid. The only one I have. My L3 cert from 3 years ago. Is this something like what you want to do?
Join the NAR or TRA. Get certified. Seriously. Go to a launch, burn one or two motors, but see a hundred or so flights. Come to Balls 17 next Sept at Black Rock, and watch us tickle the 100K waiver, staging a 48KNs P motor to a 17.5KNs minimum diameter N.
Want to see a bad ass motor failure? This is why motor testing, and rocketry in general, should be done by qualified people, in remote locations. It's my motor, a 6 grain 98mm N2900Red. Should have burned for 5.5+ seconds, but suffered a bit of an anomaly at 3.5 seconds in. The liner gave up the ghost. Listen to the sound...
I've heard that if you know someone in the states or another country where you can have kno3, you can have them order it then send it to you discretely. Just an idear ;-) Thats really sucks tho.
Hey jackoff, how bout you watch my other videos and find out why you're retarded. I don't see you building rockets anyways so please, shut the fuck up :)
Dude, check eBay... I'm planning on buying a 35 lb bag of Potassium nitrate i found for under 50 bucks, THATS WITH SHIPPING!! don't bother with skylighter there are way overprices for many things(Except flash compounds).
Just a tip. If u live in Australia like me and u might think its hard to obtain Kno3... its not... honestly, go to a garden shop and ask for "Potassium Nitrate, Grade C". If they ask what its for, just say "Making rockets".. im not scared about what i do anymore because while ppl think its illegal, there is special rocket clubs for the stuff we like to do and its totaly legal.. heaps of proffesinals do it
Soo true :)... You might also look for spectracide stump remover, or potash, or strawberry fertilizer (I have heard has allot of kno3 in it). Lowe's hardware stores sell it for $5/lb (stump remover). I just say it's for a science project :)
Ya. But if you just said that you wanted it for hobby rockets, there is no reason at all they shouldnt sell it to you. I can understand if a differnt phrase was used such as " I want it to make bombs " that they wouldnt sell it to you
LOL. I guess some people have to learn the hard way. But seriosly man, why would you mix up fuel inside? You're lucky you didn't burn your house down.
Just 15 mins ago... i nearly blew up my room and burnt down the house....i made a small batch of rocket fuel in my room.. a spark from that small batch jumped into my bigger batch of fuel and it went up..My desk..my ipod..my lamp..ruined... (Never play with fire inside the house kids!!!!!!)
My pc isnt on my desk, but my Keyboard, speakers, monitor ect was.. the only major damage done to my comp set up was the 3 small spatter marks which burnt my screen and a small portion of my keyboard was almsost melted
but wouldn't the firemen and maby police be there if your damn desk went up in smoke :P i beleave that some stuf is "fucked" but i dont think that it was 15 min ago thats all i wanted to say.
In realitity it felt like 15 mins. I realised that once Kno3+sugar fuel is burning you cant stop it without water. All the fuel that went up was in a ceramic or clay type container thing which ended up cracking and half of it fell off my table which made all the fuel spill over my table which is how my table got burned
Im not lying...My ipod is fucked because it was near the extreme heat, My lamp was right over the fuel and was insinerated (Melted).. my desk has massive burn marks all over the table about 1mm deep, why the fuck would i lie?
Quote:"i nearly blew up my room and burnt down the house....i made a small batch of rocket fuel in my room.. a spark from that small batch jumped into my bigger batch of fuel and it went up." :P i think it might be posible but highly unlikely and there are so many comments that look like this that i thought that u where another dude making "shit" comments. :P
Please, let me get this straight. You combined a high carbon content powder with an oxidizer, set a large, open container of it on your desk, then took a chunk out and ignited it, while seated at that same desk. A spark unexpectedly "jumped" into the larger container of propellant, and the resulting fire almost destroyed your home.
OK. Just wanted to make sure I'm on the right page.
And people wonder why purchase of these ingredients is restricted. Good grief.
It was a dry mix of Sugar and KNo3.. had a bowl of it and i took like 1 gram about 1 foot away from it and tested it.. a spark from the test jumped into the bowl and ~poof~
Dude on thanksgiving, I was cooking up like 100g or smoke bombs in my garage with steel powder and the stupid stuff went off in the tin can, burned my hand pretty good and filled my whole garage with somke, it was SWEET!
Lol.. i made my FIRST batch of R candy 2 days ago.. i put some of it in a really light alluminium tube (I had to crush it up and compact it in because it was rock solid.. i dont know if there is another special way to do it).. the tube was about 1.5cm x 8cm .. it had a 5mm nozzel. This fuel burned so fast my rocket just blew up.. it was amazing.. it was like ...
~pshhh..BANG!~ .. im very proud since its my first rocket fuel
you dont need to grind the kno3 too fine, or grind it all all, its the purity you need to make sure is adequate - say 96% minimum. Just make rcandy via the cooking method, its easier and saves a lot of hassle, it also produces more thrust per unit volume because of a higher density.

you fill the bottom of the pvc pipe with kitty litter and then use a metal rod to pack it solid, AKA hammer the S out of it. Then you use a drill to make a nozzle. You gotta be careful when u drill because u might knock out too much of the litter. It's a good idea to make it like .5" to .75" thick.

you can disolve the grants stump remover in boiling water then let it cool. It crystallizes into a pure potassium nitrate. you then drain the water and let it dry on paper towels for a few days.

Thanks. Yeah I put the launch for this rocket up, its called 5' homemade rocket explodes. Also I'm working on another one too its the response to this video with the mostly white thumbnail.

Run a Google on Jimmy Yawn and Richard Nakka.
Both are sugar motor gurus.

Assuming you luck out and get a good starting Kn ratio, this motor will be very progressive, and probably over-pressurize. Also, you need a delay train in your motor. You don't want the ejection charge to go off at motor burnout. Delay the ejjection chg several seconds.
Bad news is that, if your motor works, your airframe will shred. Very quickly. Too much fin span, not enough fin root. Contact me if U want 2 learn.
jmar1371 4 years ago
why dont you make some videos, master.
DMarc85 4 years ago
OK, smart ass. You don't want to learn. OK by me. I'm only a member of the NAR Level 3 Certification Committee. I'm only Launch Director for the largest, most respected TRA prefecture in the world. I only hold three research motor class world altitude records. What do you have? A blown up fincan, and a shredded airframe. Congratulations.

I don't post vids. I fly rockets. Search for AeroPac, Black Rock rockets, Snow Ranch, etc.
Search for "Dave's Q Leap 2." I made both those motors, and developed the staging system used. That little 14 pound package went over 14K on that flight. What have you done?
jmar1371 4 years ago
Ok, in case you haven't noticed, I can't tell any of that about you by your profile or unless you tell me somehow. SO, when you post tips, regardless of how inciteful they may be, you look like a jackass know it all. Apologies for wiseassness. A video might not be a bad idea either, just to back up your claims, this is the internet ya know.
DMarc85 4 years ago
OK, in case you haven't noticed, not everyone that watches vids on here is a 13 year old dumbass kid. Some of us are retired machinists, that like to spend their time accomplishing things. And sometimes, we like to share some of the knowledge that we have acquired over the years.
My first piece of advice is for you to get a long ass roll of speaker wire, and make an electrical ignition system. You want some distance between you and the motor at ignition.
jmar1371 4 years ago
There's my vid. The only one I have. My L3 cert from 3 years ago. Is this something like what you want to do?
Join the NAR or TRA. Get certified. Seriously. Go to a launch, burn one or two motors, but see a hundred or so flights. Come to Balls 17 next Sept at Black Rock, and watch us tickle the 100K waiver, staging a 48KNs P motor to a 17.5KNs minimum diameter N.
jmar1371 4 years ago
For sure. I'd love to do some stuff like that. How do you get certified? Thanks for the post on that video too. Nice flight.
DMarc85 4 years ago
Want to see a bad ass motor failure? This is why motor testing, and rocketry in general, should be done by qualified people, in remote locations. It's my motor, a 6 grain 98mm N2900Red. Should have burned for 5.5+ seconds, but suffered a bit of an anomaly at 3.5 seconds in. The liner gave up the ghost. Listen to the sound...
jmar1371 4 years ago
Now this damn thing won't let me put a link to another vid. Run a search for "JPS N2900 Engine Test #1"
We learn more from the failures than we do from the successes.
jmar1371 4 years ago
What Diameter is it?
70 mm?
looks abit like a Hydra 70mm rocket :-)

awesome rocket :D
unfortunatly for me i can't get kno3 in denmark... i have tried fertiliser and stump removers but they dont use salpeter for that in denmark
solidacid1337 4 years ago
I've heard that if you know someone in the states or another country where you can have kno3, you can have them order it then send it to you discretely. Just an idear ;-) Thats really sucks tho.

Dude, check eBay... I'm planning on buying a 35 lb bag of Potassium nitrate i found for under 50 bucks, THATS WITH SHIPPING!! don't bother with skylighter there are way overprices for many things(Except flash compounds).
Kinneticenergy 4 years ago
Just a tip. If u live in Australia like me and u might think its hard to obtain Kno3... its not... honestly, go to a garden shop and ask for "Potassium Nitrate, Grade C". If they ask what its for, just say "Making rockets".. im not scared about what i do anymore because while ppl think its illegal, there is special rocket clubs for the stuff we like to do and its totaly legal.. heaps of proffesinals do it
Crywolfy 4 years ago
Soo true :)... You might also look for spectracide stump remover, or potash, or strawberry fertilizer (I have heard has allot of kno3 in it). Lowe's hardware stores sell it for $5/lb (stump remover). I just say it's for a science project :)
Kinneticenergy 4 years ago
Ya. But if you just said that you wanted it for hobby rockets, there is no reason at all they shouldnt sell it to you. I can understand if a differnt phrase was used such as " I want it to make bombs " that they wouldnt sell it to you
Crywolfy 4 years ago
LOL. I guess some people have to learn the hard way. But seriosly man, why would you mix up fuel inside? You're lucky you didn't burn your house down.
DMarc85 4 years ago
look out for fertilizer grade potassium nitrate, its alot cheaper. over here in Australia I got a big 25kg bag for $30 which is peanuts.

Just 15 mins ago... i nearly blew up my room and burnt down the house....i made a small batch of rocket fuel in my room.. a spark from that small batch jumped into my bigger batch of fuel and it went up..My desk..my ipod..my lamp..ruined... (Never play with fire inside the house kids!!!!!!)
Crywolfy 4 years ago
LOL yeah right 15 min ago it burnt down your desk and your on your pc "right". Don't lie dipshit
molomono 4 years ago
he didnt say his pc was on his desk.
I keep all my cems separate in the shed for that reason, shit dude im glad your ok.
krssnoop 4 years ago
My pc isnt on my desk, but my Keyboard, speakers, monitor ect was.. the only major damage done to my comp set up was the 3 small spatter marks which burnt my screen and a small portion of my keyboard was almsost melted
Crywolfy 4 years ago
but wouldn't the firemen and maby police be there if your damn desk went up in smoke :P i beleave that some stuf is "fucked" but i dont think that it was 15 min ago thats all i wanted to say.
molomono 4 years ago
In realitity it felt like 15 mins. I realised that once Kno3+sugar fuel is burning you cant stop it without water. All the fuel that went up was in a ceramic or clay type container thing which ended up cracking and half of it fell off my table which made all the fuel spill over my table which is how my table got burned
Crywolfy 4 years ago
Im not lying...My ipod is fucked because it was near the extreme heat, My lamp was right over the fuel and was insinerated (Melted).. my desk has massive burn marks all over the table about 1mm deep, why the fuck would i lie?
Crywolfy 4 years ago
Further more... did i say "Burnt down my desk" ? no.. i said "Its ruined"... im going to put ducktape all around my table to cover the burn marks

Quote:"i nearly blew up my room and burnt down the house....i made a small batch of rocket fuel in my room.. a spark from that small batch jumped into my bigger batch of fuel and it went up." :P i think it might be posible but highly unlikely and there are so many comments that look like this that i thought that u where another dude making "shit" comments. :P
molomono 4 years ago
Please, let me get this straight. You combined a high carbon content powder with an oxidizer, set a large, open container of it on your desk, then took a chunk out and ignited it, while seated at that same desk. A spark unexpectedly "jumped" into the larger container of propellant, and the resulting fire almost destroyed your home.
OK. Just wanted to make sure I'm on the right page.
And people wonder why purchase of these ingredients is restricted. Good grief.
jmar1371 4 years ago
hey man.. howd u prepare the fuel?.. u made r candy? where would the spark come from
cartmansos3xy 4 years ago
It was a dry mix of Sugar and KNo3.. had a bowl of it and i took like 1 gram about 1 foot away from it and tested it.. a spark from the test jumped into the bowl and ~poof~
Crywolfy 4 years ago
oo man.. that sucks.

Dude on thanksgiving, I was cooking up like 100g or smoke bombs in my garage with steel powder and the stupid stuff went off in the tin can, burned my hand pretty good and filled my whole garage with somke, it was SWEET!
DMarc85 4 years ago
Lol.. i made my FIRST batch of R candy 2 days ago.. i put some of it in a really light alluminium tube (I had to crush it up and compact it in because it was rock solid.. i dont know if there is another special way to do it).. the tube was about 1.5cm x 8cm .. it had a 5mm nozzel. This fuel burned so fast my rocket just blew up.. it was amazing.. it was like ...
~pshhh..BANG!~ .. im very proud since its my first rocket fuel
Crywolfy 4 years ago
Haha, kick ass dude. Just like mine. So how did you construct the engine casing? Weld it?
DMarc85 4 years ago
Ok so I bought an 11lb bag on kno3 the other day and fabricated a packing rod for my engine. Its coming along.
