Unfortunately this method is not going to have success, simply because you can't mantain the same flux in gap using the low voltage taps (compared to the 192V tap) because you need substantially more current (192/12=16 times more) flowing through the wire and you are going to melt it.

 
Yes, I knew that I was dreaming when I wrote it as 12V-192V coil would be impractical. Still, it is not an operation coil but an experiment coil to prove the concept. I do not remember specifically but I think I was requested from my coil guy 50-100-150-200V coil. It might be different voltages, it is not the point. The point is that no matter what kind taped coil you would make then it would be thermal compromise anyhow as the unused turns will slow down the cooling of the under-laying turns. So, a taped coil is an experimental coil anyhow and it meant to be abused or even melted.
