Step 2Assemble the enclosure
Using your design, put the rails in. put the projectile in, and attach the injector.
For the injector decide on a good chamber volume. My injection stage was 1 foot long, so i decided to use 4 feet of .5" PVC. My valve consists of a membrane, which is punctured by a nail when i push it in. If you want to go simple, use a ball valve. The enclosure should use many bolts, as to distribute the force. Make sure you material is strong, mine is made of garolite G-11. A cost effecive material is GP03 fiberglass, check out mcmaster-carr.
Your rails should only be after the injection stage. At the front, put "fake rails". This is where the projectile is accelarated by the injector. This should be non conducting, I used teflon. Before construting the bank, fire the injector, to make sure the projecile can slide through.
The projectile CAN NOT be too lose, do as close tolerance as you can.
Keep in mind the projectile has to be diamagnetic, and conductive. The best that meets the criteria is aluminum, copper, and carbon, NOT GRAPHITE!
Test how well the chamber can hold its pressure, test the vavle a couple of times. Do not get carried away with the injctor, you want the main power to come from the railgun. I only use 60 PSI. If you do not wan to pump, add a co2 system, such as a paintball tnk. Make sure you have a regulator, or a chamber capable of the full pressure.
