Testing flash powders (for homemade firecrackers) from the most known ingredients at home. Sulfur, Sb2S3 as catalyst increased performance highly in all cases. In the case of sulfur, 10% catalyst was ideal. KClO4 Al 70/30 and KClO4 Mg/Al 50:50 they operated with significantly worse efficiency without a catalyst. Close metal powder and oxidizer ratios they operated with much better efficiency than higher oxidizer an lower metal powder combinations. The winner was Potassium Perchlorate Aluminu
I am interested in using some leftover materials that just so happen to be perfect for salutes! I would normally use just a simple 70/30 ratio of Potassium Perchlorate to Al powder, however, I have some extra materials I would like to incorporate into the mix so they are not sitting around anymore.... AVAILABLE Potassium Perchlorate - 10lb Al - 3lb Charcoal (float) - 2lb Mg - 1lb Can anyone tell me the most ideal mixture to include as much of the above aforementioned materials as p

New design, new body, a bit advanced fuel. Turn up the volume!!!
slight issues with the start that I have to figure out - but could not be happier - almost everything worked. By gps, 1km distance was travelled. Next test - will improve launch platform and will use slightly smaller diameter stainless steel tube + integrate camera.
At friday got really bored at work, called it a day and went to the garage to prepare some fuel 1) Cooked another batch of RNX propellant (oh this is fun one) 2) Cooked finally a decent batch of kno3/sugar/Fe2O3 end burner fuel After trying out different ways of cooking kno3/sugar for more than year, I believe I have finally mastered cooking that propellant type (Im talking about at least +500g batches, small ones are easy). Got most of the moisture out, packed it really well without any bubb
Long time no seen. Had a birthday and had to spend time with guests and preparing the event, so unfotunately could not get to garage But, meanwhile I have done lot of research and finally did what everything said it's not possible - huge thrust endburner from kno3/sugar! Though it needs more work as video below demonstrates. But for now I'm dealing with TOO MUCH energy and too high temperature that burns through stainless steel casing. For that I made slight changes to the engine: 1) To g
Last 5 tests have completely failed. Massive explotions. So clearly there was something very wrong with my design and decided to investigate it a bit more. It always seemed to me, that well published 65/35 % of sugar and KNO3 is too aggressive and with too quick burning speed. And my tests have actually proved it now. Plus, I got extremely good information on how the grain actually burns and the place of ignition is highly important!!! Take a look to these two videos below. Both grains are
After going through the calculations and previous test simulations then something was bothering me. I could not get the pressure under control. So after studying more my data I found out that my pressure and thrust curves were inverted and this is wrong. After careful modelling this is the new data I am using for the new test: As you can see thrust and pressure are now much more better than in prev. test. This means slight changes in nozzle design and also propellant length and core diam
Hi I'm not native English speaker so please forgive me my grammatical and vocabular mistakes I've spent months on reading and studying rocketry and 3 months ago decided to give it a try. At first, it really seemed easy - take KNO3 and Sugar, mill it, pack it and fire. Well, the first attempt actually worked and my miniature rocket took off. But after that I failed to repeat it - and I could not understand whats wrong. Usually there was no thrust - lot of smoke but that was all. Then decide
Hallo to all pyros again! i have a problem with the ball mill! when the metal starts to be fine it sticks to barrel and i don't have any further grinding efficient! Is anyone there that know what it could be? I don't have humidity here especially now at summer! please help guys because i become crazy with this thing! + the barrel is from pvc not rubber and i use chrome steel balls half inch and quarter inch!
Once I wanted to record onboard video of my rocket flight. I had Sony Xperia Go smartphone which I didn't use anymore because it was outdated. It's video recording was still quite OK, so I decided to use it as video camera. I was a beginner and for several reasons the flight failed. But I still got some video:
The Sony Xperia Go was very tough and it survived the crash. Second time my rocket was much more powerful and it landed 500 meters away from the launch point. I was not able to find
Homegrown Oxidizers Part Thirteen WSM As we continued our cell preparations by filling the titanium tubes spot-welded to our electrodes, we encountered a major setback. The thin-wall titanium tubing was seriously compromised by the spot welding process and leaked out some of the lead-free solder through the spot welds as we were trying to fill them with the copper rods and solder. When things cooled down, we held the electrodes in our hands, and with very little force, could break them off t
Homegrown Oxidizers Part Twelve WSM Making Sodium Chlorate There are several advantages to making sodium chlorate over making potassium chlorate… and a few disadvantages. Potassium chlor-alkali salts are less and less soluble as their oxygen level raises. Sodium chlor-alkali salts, on the other hand, are more and more soluble as their oxygen level raises. What does this mean? When potassium chloride is converted to potassium chlorate in our cells, the chlorate, being less soluble than th
Homegrown Oxidizers Part Eleven WSM After drying and storing our homegrown potassium perchlorate, we need to test it for purity. This step could just as well have been done before drying our samples, but we wanted to do all our testing at the same time. The primary contaminant of concern is sodium. Sodium has very strong spectral lines (primarily yellow) that interfere with color production in pyrotechnics. In fact, the least amount of sodium will usually mask the weak violet spectrum of pot
Homegrown Oxidizers Part Ten WSM We’ve run two batches of sodium perchlorate, one with a platinum anode and the other with a lead dioxide anode. Now we have more than five liters of raw sodium perchlorate solution (contaminated with an unknown amount of residual sodium chlorate). The next step in producing potassium perchlorate involves the destruction of the chlorates in the cell solution. The treatment of choice is the gas, sulfur dioxide (SO2). Lacking the resources to buy and safely hand
Large Case Formers! Do you really want one? Well, if you do and don't have a big lathe maybe these ideas can help you. I had a smaller cheapy lathe that I bought from a big box store. They don't sell them anymore and I burned mine up trying to make a former that is larger than an 8 inch'er. I contemplated what to do about this and I came up with a solution that went sideways...literally. Instead of laminating blocks of wood and machining them round I decided to take flat sheets and cut them ro
I am always trying to find a safe inexpensive ways to improve my fireworks. Last 4 th. of July I came up with nice replacement for fire cracker tubes which can also be used as reports in a mortar shell. I had ran out of tubes and forgot to order more in time for the 4th. I decided to run to Menards to get some hdpe pipe to make mortar tubes. As I was walking in the pipe section I noticed a shelf with 5 foot 1/4 inch terra cotta pex tubing for $1.59 a piece. I cut the whole thing in 2 inch pi
I've had or made about 4 different versions of ball mills in my day. When things got serious and I moved up to a large ball mill the one thing that never changed was the mill jar that I use. This style has been an "old faithful" for me so I'll share what I have done. The material I use is schedule 40 PVC plumbing pipe and parts. There is a lighter duty PVC pipe known as Drain, Waste, and Vent (DWV). I've lived through a couple of dropped jars in my day and I would like to give the rigid schedule
I read here that PARLON works well coated magnesium, I'm doing blue stars with ammonium perchlorate and have used magnesium coated with potassium dichromate, but I want to try PARLON, but still do not know if the procedure is the same Like with dichromate or change quantities, porfabor if someone knows how PARLON add a kilo of magnesium I would greatly appreciate it.
