Sorry, no dying for any of us (if we can help it) until we get to see the finished product.A rocket powered syringe with grid fins...I can die happy now, cause I've finally seen everything.
So, my twin brothers launched a 2-stage HPR during this past Springfest in Las Vegas, and we got talking about ejection charge canisters that pass the wires through the bay lid instead of using terminals on its outside; he was really impressed with the ease of use and performance of the E-Match Mate Bulkhead Adapter Set sold by Apogee that he had used for those ejection canisters.
After looking over his installation, I decided to create a similar system to use for the primary and secondary main parachute charge canisters on the ANTI-VIRUS... these canisters will both look something like this:
I did cut the plastic shroud down from nearly 3/4" to 1/2" in length so that the initiator is right at the top of the shroud, almost peaking out. The hole for the O-ring is 11/32", the hole for the plastic shroud is 15/64", and the exit hole is 1/8".
These initiators (e-matches) can be purchased directly from MJG Technologies Inc., with the plastic shroud installed. But, the initiator needs to be pushed out of the shroud, and a small amount of 5-minute epoxy MUST be put on the wires just below the initiator so that, when the initiator is pulled fully back into the shroud, the epoxy seals the small gaps around wires. When the epoxy has cured, you are ready to assemble the charge canister.
Each assembled canister screws through a threaded hole in the top of the bay lid, sealed by the outer O-ring, allowing the initiator wires to go straight to the electronics without any mid-point connections.

I saw that flight. It was impressive. Your canisters are ingenious.
Is this person really your better half then? LOL, couldn't resist. Sorry for the new post on old thread
Next time (cuz I'm *sure* there will be one
), increase the plunger end diameter and put a ringtail grid fin on the end!
Canister design looks neat, although it worries me that the eMatch is under the BP. Generally you get better % of BP burnt if the ignition is on the top. With ignition underneath it scatters the BP somewhat.
Finally ready for the application of the graphics…
It’s been a long road for this build.

Pop lugs, not drugs
Looking really great!
Today... is body wrap and assembly day...
And, now, without further adieu, I give you... ANTI-VIRUS...
With its first public appearance at the Tripoli Las Vegas Oktoberfest Regional Launch...
Are you ready to get vaccinated at near Mach speed?

Definitely EUA, it's been way too long of a wait already.
Absolutely fantastic.
I'll get to see it in person. Oh boy, this is going to be good.
I reslly like the way it ended up. Great build,

Awe-inspiring! Love your graphics too.
@H. Craig Miller how tall did it end up being?
68” plunger bottom to needle point.
When the new OpenRocket version is released I’ll post a design file.
THAT IS A GREAT LOOKING ROCKET AND REALLY IS A WORK OF ART. I am looking forward to flight videos.
I'll look forward to it, BUT won't be holding my breath....the carrot of a new OR version has been waved in front of us for so long.... oh well, eventually.
And, now, vaccinated... at 500 mph.
How close can you stand... without getting the ANTI-VIRUS jab.
Much thanks to the folks of Tripoli Las Vegas for a great Oktoberfest 2021 launch this past weekend...

motor?
It flew on an Aerotech DMS J450DM-14A Metalstorm DM.
My only regret is not using the slow motion mode... and having one panel of the Fruity Chutes Iris 60" parachute slightly sliced by a grid fin; ouch, oh the pain (if you know what I mean).
