RE: [TCML] nst

["Lau, Gary" <Gary.Lau@xxxxxx>]

I'm not sure that a short between laminations would be a problem.  I've seen cores built where a welded bead held all of the laminations together.  I would be more concerned that milling or drilling might just munge up the nice flat laminations into a mess.

You lost me on the PVC part.
