I used silicone putty for bathrooms and I did just a single grain. Both ends of the rocket were machined from steel rod on my lathe and screwed into
the body. The nose part had a small reservoir which I filled with an easily ignitable thermite pyrogen, I think it was based on CuO/Mg. I don't recall
the Kn, but the throat was around 2 mm IIRC. The burn time was much less than a second, maybe around 0.2 seconds, and it seemed that the SiO2 tended
to condense on the nozzle rather than erode it (at least in static tests).

Thank you! Did you use steel for the body as well? I like the idea of containing the igniter comp in the nose plug. Working on some new AN now and
i´m eager to get this propellant to work!

I generally used aluminum tube for the body, but did do a few with steel bodies. I didn't notice any compelling reason for using steel in the tests I
did.
