I use 40 mesh Mg filings, really burn with that LOx lead plus the rich
combustion products of solid propellant combustion.

I made my own version of the estes to do just that. Take a 1/8NPT
nipple. Put an end cap on it. Drill a hole in the end cap for a glow
plug. Mix up your favorite sugar motor compound. I used KN/Epoxy instead
of sugar. No cooking required and I added a lot of iron for nice hot
sparks.

This is just an inexperienced shower thought, but could one use a small
Estes motor in some kind of orthogonal mount flush to the chamber wall as a
liquid engine igniter?

I second the recommendation for a spark torch igniter, which will also
serve as a team building exercise that improves confidence. Once you have a
reliable ignition system your team can move on to the next level.

From personal hands-on experience with TEA it's not ,my first choice for
an ignition system. TEB costs an order of magnitude more,i.e. $20 vs
$200/gallon as of 20 years ago. It depends on what you're igniting, how
many times,how often, ground vs flight,etc.. I prefer a pyro for one shot
or limited cycles and a so called 'torch' ignitor for multiple and
repeatable ignitions.

Any guidelines for storage and handling of small amounts of these
tetraethyl compounds?
Any recommended purveyors of small amounts?
Thanks, Edward Jones
