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.

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.

I - E-match Testing and Serialization
- Give each e-match a unique serial number.
- 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.
- Staring 2 inches from the igniter head, mark the serial number in binary on the igniter wires. Use the Sharpie.
- Measure the resistance of every e-match with the multimeter.
- Log the resistances.
- Dispose of any shorted or open e-matches.
- Short the e-matches by twisting the leads together.
- Log the date and your name.
II - Bolt Perpetration and Insertion
- De-grease and clean the machined bolts with acetone. Use the bottle brush to clean the insides. Let the bolts dry for at least five minutes. Any residual grease or acetone will inhibit the bond.
- Slide in the e-matches
- 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
III - Gluing
...
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)
...
IV - Inspection
- Test the resistance of all e-matches with the multimeter. Log the resistances.
- 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
- If the resistance has dropped, then the e-match has shorted. Record the probable cause of the short in the table.
V - Cure and Follow up
- Let the FireBolts cure for at least 24 hours.
- Fill out the FireBolt Firing Log when firing the Firebolt.
