repalcing a old entry door knob

I have a 60+ yr old house and the existing door knob has a smaller diameter than any replacement knob/lock set up i can find at the local they still make this smaller diameter door knob, or do i need to drill out a new hole.

if i do have to drill out a larger hole, should i enlarge the existing one...this may be difficult to center the hole saw bit exactly in the center

You may be able to find the older locksets at antique stores, etc. But if you want to drill out the door, place two pieces of 1x6 on either side of the door, square with the edge and clamped tightly. Measure back the proper backset and drill through the first 1x and the door, and allow your pilot to penetrate the back 1x. Remove the cutter, and continue from the other side until you get a clean hole.

There was a post many months ago regarding how to drill an existing hole bigger using a hole saw. What I would do is clamp a piece of wood onto the door, mark the center of your new hole, and drill the new hole with the correct sized hole saw.

Another idea would be to drill the correct sized hole out of the scrap of wood FIRST, then clamp that cutout in place where the hole needs to go, and use it as a guide as you drill your hole through the door.

They say there is more than one way to skin a cat, although I've never tried to skin cats. ???
