I need to bore a 2 inch hole in some 3 inch thick planking. I then need to insert a tight fitting metal sleeve inside the hole. The metal sleeve is held in place by a large top surface flange that has screws going into the planking from above. If you've ever used T nuts, think of a giant T nut inserted from above that does not have internal threads.
For the life of me, I can't remember the name of this fitting! Bring anything to mind???
