I think he does not have a pneumatic drawbar but also he most likely made the spindle himself. Bearing most likely are not abec7 high precision matched but maybe like abec5 matched set that could be had for like $100-$200.
I wonder if his spindle is even heat treated and ground. Or even you can buy a 30taper spindle from tormach for like $600. Or if you get their r8 spindle you could even add their pneumatic drawbar.
