OK. So the wife goes out and buys new hardware for the bathroom door. I remove the old hardware and find I am faced with a 3/4" hole. The new hardware requires a 1- 1/2" hole. I've got a set of hole saws so the size is not my problem. My problem is how in hell do I keep it on center-line? There would be no problem if there was no existing hole but the pilot drill for my hole saws is 1/4" -- rather sloppy in a 3/4" hole.
I am wondering if someone manufactures guide bushings for such an ordeal. If I was still working I'd make my own guide bushing -- but I'm not. So now I am married to whatever is commercially available. I have seen nothing. Surely builders and home improver's must run into this same problem quite often.
Hmmmm. Do I smell a business opportunity?
any known trick for this?

You can buy a door hardware installation tool. They are adjustable and have both a holesaw guide for the bolt as well as the opening for the knob acuator.

Re: any known trick for this?
Don't know what your holesaw set looks like, but can you sandwich a 3/4" holesaw and the 1 1/2" holesaw bit in the provided rig, using the smaller holesaw as the guide? This is possible with the set I have, but they're all different...
Otherwise maybe just mark the circle you need, press hard, close your eyes and go for it without a pilot? (Much more my style)

How about gluing and stacking washers in the 3/4 inch hole, or filling with plastic wood?

Re: any known trick for this?
Take a small piece of wood, screw it to the door with 2 screws approx. 1" apart over the 3/4" hole. Drill your 1/4" pilot hole centered in the 3/4" hole, Then drill from the opposite side with your hole saw, may have to use a longer bit in the hole saw to reach the whole way through. When the hole saw breaks though the door the screws should be inside the cut circle and the piece should fall off.
