I realize I could spend hours searching the forum for what I need, like I've done hundreds of times. But I know the pros here are the best. I'm looking for information on making coils. Very specific. Such as size and windings and amp draw. Any leads in the right direction would be very appreciated!

What type of coils are you talking about?

Most coils are Machines Specific.

I wasn't aware coils would be machine specific. I have a PI machine I built myself, it is a Gary's Pulse 1. I thought there might be an estimate available for how many amps a certain size coil might draw for any PI machine. For example: about 150 mA for a 9 inch and maybe 250 mA for a 12 inch.

Size does not effect the A-Draw.      Larger coils still have to be the same Z impedance.   Same R Resistance.
