Mike,
I used to have the pleasure in having access to a friends wood working shop anytime I needed it , had my own key to the shop, about 20k sq ft. He had a drum sander to die for. It would handle a 6ft wide piece and would go down to a thickness of 1/8". It had roller in feed and out feed tables that were 12 ft long each. LOL!!
A tornado took out the shop a few years back and he retired. Oh well.
