Hi, well maybe some is made with soft steel but most have silicon steel for
laminations. making laminations from sheet metal might work but results
would be poor. A electrical shop, machine shop, motor rewind shop, or a
junkyard would be a good source for laminations. There must be a blown
transformer, ballast transformer you could have for little money. I can get
them just for stripping the copper off them from my junkyard. cul brian f.
