I have been searching on google and found nothing that would help me. I am new to RBA and everything that is rebuildable. I own Orchid v4 and kbox. I also have 24awg wire and i have problem with sizing it. I have made 2 coils on a screwdriver that came with Orchid (don't know the size and cannot estimate it due to the screwdriver being really small). Each coil had 10 wraps. I have put the coils into the atty and kbox refused to power it. I took one of the coils out and kbox powered it. I realise that 2 coils is going over 0.4 ohms. So i would like to ask how many wraps would i need? What size screwdriver or drill bit should i use for it too. I was aiming to get 0.5ohm or 0.6ohm. Saying it now: Please don't give me links to calculators because i don't understand them.
