As of 11/7/18 there is an unresolved issue with the e-match shorting on the steel screw. One proposed solution is to use nylon screws instead.

- Paper Towels
- Bottle Brush
- Gloves
- Sharpie
Fabrication
Machining
FireBolt fabrication is simple. First, purchase 1/4-20 1/2" stainless-steel cap-head machine screws. One by one, perform the following procedure:
- Secure the bolt in the chuck (preferably a collet chuck for a 1/4-20 screw) of a lathe (head end pointing outward).
- Using a center drill, create an indentation in the cap.
- Using a 8-32 tap drill size (size 29), slowly drill through the bolt. Use coolant or oil to prevent overheating of the drill bit or part.
- During the initial production round, we used a speed of 400 RPM and a feed of about 0.001" per 1-2 seconds.
- Drill approximately halfway through the bolt, bring the drill bit out, re-oil it, and continue drilling.
- Do not let the drill bit sit inside the screw without moving it.
- Tap the hole with an 8-32 tap.
- Turn OFF the lathe.
- Replace the drill bit with a center.
- Tap through the bolt with good form.
5. After removing the bolt from the chuck, secure it in a pair of pliers.
6. Use a grinder (or a drill press with appropriate mounting) to de-burr the end of the screws, which may have sharp pieces poking out of them.
E-match Insertion
...
- Staring 2 inches from the igniter head, mark the serial number in binary on the igniter wires. Use the Sharpie.
- Zero: 1/4" tick parallel to the wire
- One: Tick perpendicular to the wire
- Log the serial number and the color of the sharpie. Log the type of e-match.
...
- Log the resistances.
- Dispose of any shorted or open e-matches.
- Short the e-matches by twisting the leads together.
...
- For Standard FireBolts, slide one e-match through the hole in the 1/4-20 bolt.
- For FireBolt Jumbos, slide two e-matches through the hole in the 1/4-20 bolt
...
On the other end of the screw, you may be able to push a small amount of epoxy on, but don't get it in the threads. Log the time. (ELABORATE AND QUALIFY)
...
- If the resistance has dropped, then the e-match has shorted. Record the probable cause of the short in the table.
- Dispose of the FireBolt.
- Dispose of the FireBolt.
- If the e-match is open, record the probable cause of the break of the circuit in the table.
- Dispose of the FireBolt.
- Short the e-matches by twisting the leads together
