Brief Description: Cut the inboard rib with drill press and fly cut
Bought 10" drill press from Orchard and fly cutter from MSC tools. First hole cut - $cost 200!! Took 45 minutes to set up and find center. Mounted / clamped to drill press backed with plywood (to give cutter something to cut into. Worked really well. Dialed in drill press laser marker to center point. 'OK' as a reference
