I need to make some igniters. Anyone have a recipe they love and tips
on where to get the ingredients? Gary, the igniter you gave me at the
July launch worked great! Dave, the igniters you've given me in the
past have also worked great.
Thanks for any recipes!

I know those guys have some great formulas, but in a pinch Newton's 3rd sells kits. I won one in a raffle a while ago but haven't gotten around to using it.
The only thing I've ever used was ground up sparklers bound with nitrocellulose (ping pong balls and acetone you know), worked OK on MPR, but nothing like the thermonuclear concoctions the pros use.

Michael,
My igniters were made using a FireStar kit:

I used to buy their wire but now I have just bought shooters wire and
nichrome in bulk to make my own.

Michael,
RocketFlite makes a good igniter formula that you can get through
PML. I use shooters wire & a strand of copper lamp cord, they have
all worked well.

Thanks Gary and everyone, I'm giving this approach a try. Hope to get a few made in time for the August launch, at which time, life permitting, I'm going to try that L3 again.

Can you tell me how to make these FireStar igniters? It came with
exactly no instructions. I emailed the guy and haven't heard back. I
have the wire, the pyrogen and the oxidizer.
Thanks!

I would add that if after mixing for several minutes there are still lumps
in the mixture you will need to add a small amount of thinner (bottle C) but
don't over do it! The mixture will take about 20 minutes to dry. Also, your
igniter wires prior to and after completion should have a resistance
measurement between 1.0 and 1.9 Ohms (1.5 Ohms is the nominal measure).

While that is a good reading for Fire Star wires but if you roll your
own you may want to experiment a bit. Different wires have different
resistances and different physical properties. Too little resistance
and it may burn through before the pyrogen ignites, too much and it
may take longer to lite if it lites at all. You also have to factor
in the properties of the pyrogen but I can talk about thit one
later.
Remember OHM's law when you think about the wire. at 1.5 Ohms you
will have 8 amps acrossed the wire where 2.5 Omhs is only 4.8. That's
a heck of a difference for a 28-32 gauge wire.
The best formula for igniters I have come up with so far is 70grams
very fine AP (the finer the better) 5 grams 400-300 mesh Aluminum 5
grams copper oxide and 10 grams 50-100 mesh titanium if you can get
it. mix with ping pong ball goo. Dip and enjoy.

Not quite ohm's law, actually it's the formula p=e^2/r. e is the voltage, r is resistance and p is power, in watts. Just a little increase in voltage can make a big difference in the heat generated.

Thanks guys. I now have 6 igniters dipped and ready to go. Gonna test
one tomorrow and make sure they work. My resistance is right at 1.5 so
I think I am good to go.

I made no mention of watts nor VA but the point is still the same, be
aware of the effects of resistance in your igniters.
I once had some wire that was a bit thin and would burn through too
quickly so I wrapped the wire to get a 2 - 2.5 ohm reading and they
worked like a charm. I have also had thicker wire that was slow as
hell so they required about .75 - 1 ohm to fire up reliably. Also the
more sensitive the pyrogen you need less heat (watts) for it to go
because just the slightest little bit of heat will set it off.
That's how an E-match works, it uses a very thin nicrome wire that
only takes about 1 amp to burn through. We can have Wayne do the math
on that one but it really doesn't matter because the wire burns
through before it even gets close to the full amps.
The only real point I'm trying to make is "If you are making your own
wires to dip into ANY pyrogen test a few first". It's cheap easy to
do and might even be kinda fun :)

My tests were successful. I will bring a few extra to the launch in
case anyone needs any.
