I am not sure if this will help but one ( or two ) of Roger Smith's 
videos gives a very good account of how he built his inductor from a 
scrap transformer ................. a MOT should do for the inductance 
you need
Here is one of Rogers Videos you may have to search through  .. More 
from  ROGERINOHIO ... to find the one you want
