So I trimmed out my back door today, and then decided to make something for my coil gun.
I purchased some .5 id .625 od poly-carbonate tubing a while back, along with a little 6v motor. So I 3d printed a motor mount and a magnet mount (attaches a magnet to the end of the motor shaft.)
The motor mount has a hole that I will thread with a 8-32 tap and it will except a threaded rod to be used as repositional stop so I can test projectile placement in relation to the coil.
The projectile will attach to the magnet, the motor/projectile assembly will then slide into the barrel, motor will spin up, coil gun will fire, and hopefully will have a stable ballistic path.
I also printed out some new coil endcaps that will also be used as my new photo gates. I expect to push nearly 4000 amps through each of the new coils, I am also hoping to reach projectile speeds in excess of 500 feet per second.
