The cleanup went surprisingly easy...I created the "world's largest shop vac" and sucked it all up. The hose wouldn't reach on it's own and I had a spare 5' piece of 4" quick connect duct. Voila! Now to be clear, since I use a Harvey G700 in my shop which does not have pre-separation, this whole area was already cleaned prior to the benchtop flattening so I knew there was no metal on the floor. When I was done with about three minutes of waving that heavy thang around, there was only a very small amount of remainder to be sucked up by the shop vac.

I moved on to the sanding and finishing stages and will post a final photo when this little flattening and reconditioning exercise is complete.
