I have @ 80 feet of laminate steel for making the EI core needed for the Meyers Bobbins I drew up.This material was bought from a core manufacture.It is grain oriented and measures .010" thick X 39 inches wide.I will sell it by the foot at 39" wide for $5.It already has the coating on it,and can be cut out with a laser,and it doesn't hurt the coating.
I have attached pictures of my core so far.You can see the E and I, I made.You will need 75 pieces of each.They can be all made from a three foot piece if laid out and cut with a laser.Other wise it may take more if you make them by hand with sheet metal shears.I cut mine out with a guillitine paper cutter.But it takes time.
