Newly acquired property, has door locks that a scrawny kid could rip off with a pair of Channel-Lock (TM) pliers.

So I got some one-inch deadbolts, all keyed alike, so one key can get me in to ANY door.

Trouble is, the new lock needs a bigger hole than the old one.
The usual way to put the new lock in, is to make another hole in the door.

But I didn't want to, on one specific door.
Without a solid center to aim the hole saw's pilot bit into, it would be quite a challenge to hold the saw steady.

So I got a CHEAP plastic cutting board, drilled through THAT, clamped it over the existing hole, and it guded the saw perfectly.

Here's a picture of the rig.

Thank you for a magnificent solution to a never-ending puzzle.
This goes far, far beyond just a lock cylinder in a door.
Thank you, Mike

i just stacked 2 hole saws together... first one on is the hole size you want ,,inside of it is the hole saw size you have got in the door using it as the guide,,,,works pretty good.
