Hmm, I know this is an old thread but wanted to comment here.

The comments about shimming and time required for changing dies seem off to me. If a machine is set up properly with a matched set of dies (all at the same working height) then the die change should be very quick I'd think. Less than a minute, just as long as it takes to drive the wedge out and back in, with a check to make sure the dies are aligned.

If they dies have slightly different working heights, then shimming or even changing the height of the anvil block would be necessary. If the arms or die travel isn't exactly square then you have a problem getting a clean contact patch (and yeah, that would be a big pain in the butt to change dies then).

FWIW, at Fay's class he changes dies just that quickly. Yeah, he's Fay, but I'd bet he has his machines dialed in to make that possible.
