To double-check that we're talking about the same thing, this is a listing for the bottles I'm talking about: https://www.ebay.com/itm/154047574899 Or https://www.ebay.com/itm/275937666427 Many people have had good luck. The first link are the exact same geometry. As long as you're just doing chloride->chlorate, they're fine.

I made a tooling for 5/8 I'd core burning rocket, the spindle is 4inch in length and 8mm in diameter and its non tapered, from top to nozzle is both 8mm. Does it still perform good? Despite the non tapered spindle and what you guys think about the outcome, thanks for answering my question

Thank you for the info guys. I’ve run it for three days previously to today and produced around 15mm in a 500ml jar of chlorate (needs to dry before weighing) but looks very good quality so far. I’m going to upgrade all the gear with a variable power supply and some better anode and cathode that Arthur showed me, but need a bit more cash for this so end of the month I will be treating the wife so I can treat myself lol. This was just a quick trial after more reading and speaking with Arthur and I had all the gear apart from the £12 Anode. When I get an idea I just can’t wait!!!

You shouldn't buy those, they fall apart. The electrodes he bought are a good choice.

The assembly is good with the MMO anode, but the adapter is not. You will need a minimum of 4 amps and max 6V with these MMO anodes. The problem with the current power supply is that the circuit can be overloaded, and the cell will also produce slowly. Buy a 6V 4A car battery charger. The battery charger should not be a small digital one, use a larger type what should have a 6-12 volt switch and an analog charge meter. I see that it contains freshly made brine. Electrolysis will slow down as the process progresses. What I would replace that container to a 2-liter screw-top plastic mason jar. I would run the electrodes deep below the solution. 1000mA or even 2000mA adapter is not really suitable for production. It might not be ready after another month. I think whit this pair of electrodes can easily pass through the cell 1 amp or more, but they are very far apart. If you can't insulate the cell well and the chlorine are leaking run it outdoor. It is worth adding a few meters of 20 amp 1.5 Sqmm single core black and blue wire. If you want KClO3 from concentrated KCl solution the production time will have a fraction compared with NaCl.

Dark - You can get those same MMO anodes a lot cheaper as the "sanitizer generator" bottles on eBay.

This is Ttger tail (0.88) with #100 Ti (0.12) comet. GX010200.mp4 It worked as I hoped so I put it in with Buell green: GX010201.mp4

New setup. Different anode and power supply, using Sodium as the base to start this time. Added a lid with a gas release pipe and an access point to top up the sodium and check and adjust PH. IMG_5059.mov

Thank you.

professional shells, Have good days

something similar to a dough(paste) ? I asked this, because working and making nozzle with a dough mixture is easier than other methods, when we dont have nozzle instruments.

That's impressive..!! 👏

I agree these stars are worth trying despite the hygroscopic nature of sodium nitrate. I believe there are different grades of NaNO3 on the market, but stars should stay dry below 70% relative humidity with good quality material. My homemade sodium nitrate is recrystallized 3 times and stays dry below 70% rh. Shimizu states in his book that real pure NaNO3 attracts moisture first above 85% rh. But I have no clue how the purification process for achieving this is done. Anyways when the stars are first in a pasted shell, I believe the layered pasted paper provides some protection against humidity. I also read somewhere a guy who lined the inside ball shell halves with pvc kitchen film, and sealed the contents of each shell half with this before closing the shell.

I have to admit I have never used NaNO3, but this thread makes me want to experiment! When it comes to hygroscopicity, has anyone tried to coat or prime these stars with NC, Phenolic or PVB? Maybe it doesn't help much in the long run, but it sounds good in my mind....

cmjlab, I'm not sure I get your rant? In my eyes both you and Frank are on the exact same page. He was referring to the previous poster I think. It's a good rant, but I think you got it wrong

Every binder has it's own best liquid activator, each binder and activator needs to be compatible with all the chems in each of the star formulae, but a star comp without binder or activator liquid will never harden.

Thank you🫡

I dry every stars for atleast 3 days in hot weather and 4 to 5 days if weather isn't hot enough. Do remember it reabsorbs moisture even if it is dried out well and you have to store stars in moisture proof bags.

Fantastic display

That's a good point. I let my batches dry for a day and a half and that probably wasn't sufficient.

I cleared the cookies on my phone and locked myself out of my account. But I figured it out. Didn't want anyone getting the idea I blew myself up or anything....my transmission did but that's for another website.

Why would someone ever minimize the hazards associated with three component milling? If you blow up your garage that's one thing, but spouting ignorant bull shit on the internet can have more far-reaching and severe consequences than that. Debates can be enlightening; even animated ones. I hope that all the forum members can remember that we share a passion for fireworks as we argue our positions.

You may use clay or bentonite for making nozzle. I know people who use mixture of cement+sand in some cases.

I think you've got me confused with someone else...

To everyone else who has to read this bullshit, I truly am sorry. It detracts from the overall usefulness of otherwise informative threads and valued input from many different people. This type of response is against everything I usually stand for, I'm just tired of people who state everything as "fact" without any empirical data to back it up, and even when they do, feel it necessary to call everyone else's input "nonsense". Anyways, I am done. I won't contribute to the slinging contest anymore.
