No can do. Anyway, our thickness needs might change over the years it
takes to go through the amount we have to buy each time, so slicing
off a chunk to send out for machining is what I aim to do.

Not for nothin', but it might be cheaper to send AND ship back the whole
piece to a shop that can handle it.

That's a big lump o'metal. If the shop is in a 50 mile radius of you, it
would probably be cheaper to do it that way.
