I'm trying to build some ballasts. I have found the right cores and clips and "stuff" but I don't know the proper way to gap the e-cores. I understand it is the center leg that gets gapped but i'm not sure if i can do it or if i have to buy them gapped. Do I take it all off one side or 1/2 one each core? One gets gapped at 1 mm the other at .5 mm. The core is an E30/15/7.
Thanks for the help!
