Are you making just 1? If so, just put strap clamps on the long sides(three per side) and mill the short sides. Then clamp the short sides(2 per side) and mill the long sides.

Stack them. Mill 4-5 at a time.

Not sure what you're asking then.

You want to bolt them down, mill and chamfer. Go ahead.

How accurate do you need the chamfers to be? To mill I would think you could get away with every 6"-8" apart, especially if you used thick 1" washers.

This sounds like a good candidate for a vacuum table to me.

2 rows of 3 bolts with a long strap clamp should be all you need. We make our own, just grab a chunk of 1018 flat stock saw to whatever length you need, and drill 3 clearance holes in it.
