The main issue which many seem to be forgetting here is that powdered rocket propellants, such as any chlorate based which I know of (being sugar,
charcoal, etc), must be pressed into their casing to solidify the grain. This can involve a hydraulic press, an arbor press, or just a dowel and a
hammer. These pressures of forming the grain, and also the danger of accidental ignition by friction are what make chlorate based rocket compositions
so unforgivably dangerous. Back when I first began in high powered rocketry I had asked about using Chlorate for engines, and was immediately reamed
out... As it turns out they knew several people who in years past had tried either pressing or hammering chlorate based grains, which not only caused
accidental ignition, but detonation in the case of the hammer method. Its simply a matter of who wants to win the Darwin awards. When there are MUCH
safer alternatives easily accessible for equal if not lesser cost, why pose the rick to yourself and others?
BinaryClock, I hope you consider trying the Potassium Nitrate and Sorbitol propellant, after many years in rocketry this is by far my favorite
propellant. Sorbitol is pretty tough to find now a days, so shoot me a PM and if you are interested I can mail you some for the cost of a small flat
rate box. Your son will probably thoroughly enjoy the melting and casting process. It feels like like hot silly putty, but its rocket fuel!

Don't get me wrong, I wouldn't have even tried this comp without treating it as you would when working with whistle mix. Press everything from behind
the press's blast shield. Only thing I will hand ram is black powder rockets period. When trying a new comp, always start small, the smaller the
better, then work your way up in size and diameter of your rocket motor.

Did you make Chlorate? (in sensible quantities) or do you know of anyone who has (except kewls with vague recollections of doing so!)

Because I'm not 100% sure, I will not argue, but I want to know the scientific principles why metallic lead cannot be used as anode? It forms PbO2 on
it's surface in situ, and although it partly flakes off during reaction, I can't say what causes it not to work? Would it passivate or cause
alternative chemical reactions?

electrolysis with lead would be great to have the lead broken down into a powder of some sort, wouldnt it?
i actually have an idea about PbO2 and graphite, although this might never be attempted --- wrapping PbO2 or graphite stick or powder into cloth or
similar, wrapping it very tight so it stays in shape, this should then be able to conduct electricity and not crumble apart
one problem would be that the top of this which you connect electricity to might be soaking up all the solution and thus performing electrolysis
aswell on the piece you decide to use to connect it all with, although it would work with a small piece of platinum etc to get a decently sized
electrode

Not sure if any on you have ever found the following site but he has very good pages on chlorate cells and some useful electronics pages if you search
the site.
