Coilgun update

So update on the coilgun with some pictures. Charging circuit is done. I used Uzzor's modified Mazzili driver
To charge the capacitor banks to 375V.  I got this idea from Jason's 1.25kj coilgun. Actually his coilgun was the inspiration for mine. Things I'm doing a little differently are: 3 stages (2 optically triggered) with less energy per capacitor bank, shorter slug about .30 caliber, a 14.4V 2100mAh NiCd battery instead of his 12V NiMh. I will also have a bolt mechanism like a rifle to position the slug in the initial coil.  All cap banks will have to be charged separately due to not wanting them hooked together when firing so a switch will separate them. The optically triggered stages will be designed based on the time the slug is in the coil determined by initial velocity (from the previous coil) of the slug. This should make the coilgun much more efficient and achieve a greater final velocity. Stage 1 will have only about 1000uF capacitor bank while the following 2 stages have a 4800uF bank. All capacitors are charged to 375V which is 75% of the working voltage of these capacitors.  More theory and details to follow but as for now, some pictures of the coil winding, capacitor bank building and the battery pack building.
