Ideas:
- Switch to a single pathway into one capsule instead of a branching fitting into two capsules
- Sandwich aluminum burst disk between two fittings and thread a modified firebolt (or two, for redundancy) into it
- What pressure are the gases from the black powder?
- TO-DO: Test sealing the e-matches in with hot glue instead of epoxy, would make integration less hazardous/quicker and re-use possible
- Design 1:
- Reducing adapter 50785K612 (3/8" F x 1/8" M)
- Plug w/ ext. hex drive 50785K23 (3/8" M, hollow)
- Drill two holes for two e-matches
- Burst disc
- (Heavy duty?) aluminum foil with maybe an o-ring or something to hold pressure (might just work without it though, could use RTV gasket if necessary?)
- Tape (aluminum duct tape, maybe just regular tape would work)
- Angled washer to promote good sealing
- 3D print with a softer material (flexible resin? TPU?)
- Faucet washer: 2801K24 (kinda thick and not exactly the right angle/diameters)
