ok thanks sorry about all the type'os im useing my phone and running a cnc at work at the same time so im not to good at multi tasking ..
so your saying cut down on my banks and coils from 10 to say 3 would be a good place to start . i have only tested one so far .and it only moved the round 6 inchs .. with one cap .. witch seemed to have way more out put then i expected .. useing that 30amp 12volt auto relay ...
haveing the arduino with one coil would be a waste i would think .. but spread the 3 coils and time the relays with arduino would be ok right .. and im not worryed about hurting myself i do see the dangers but its just for fun and i plan to use my ushal coman sense.. soo if you think 10 is to many ok but 1 is not not going to do it with what i have for a setup in less i did my coil winding wrong and should make a new coil becuse im geting plenty of power and spark and burnt out stuff with lil progress on moveing the round threw the tube .
