Gladly, don't have much actual work done yet, but have been finishing up my circuits and waiting for materials to arrive.
beginning of machining for barrel:

its made from3 layer 1/2" lexan polycabonate and is held together by 50 some grade 8 1/4" bolts to prevent it from exploding under pressure
the problem is not from the pressure of the injector (2000psi) but as extreme amounts of electrical current flow through the armature parts of the metal vaporize into plasma that can place up to an additional 5000 psi of force along with the force applied by the two parallel magnetic rails which create an incredibly strong magnetic field (up to 2 teslas)
heres 2 of my 24 capacitor which will allow me to use low current such as a car battery with inverter of standard electrical AC current to produce huge jolts of electricity up to 50,000 amps (most wall sockets have a fuse set to 5-15amps):

the quarter is there for reference size and the large red thing is a solid state silicon controlled rectifier (basically a large electrically controlled switch).
2/0 gauge copper wire (about 1/2" diameter):

will carry the electrical current from capacitor bank to rails although it is still still far from rated to handle this current and if the current was constant it would completely melt in less than a second.
I'll add some stuff later
Cheers!
