I had an idea to scavenge an old drill press and retrofit the electric motor with a hydraulic motor. Then this could be powered via the remote hydraulics on a tractor. Mount up the drill press via 3 point hitch and build a mobile pipe notching station. The hydraulics would provide adequate power to cut through anything that the drill bit or hole saw could handle. I would think that this would have to be rigged up via pulley system to allow slippage on the belt because the drill bits would shear off under the load of a hydraulic motor.
