door and hole saws?

Question

hi .. I have a preexisting hole in my front door...switching out locks..and this one is a bit bigger..

so I thought I would use a hole saw on the end of my drill to cut it bigger...big mistake...the drill basically 'took off' and left nasty looking marks in the door..
is there a way to enlarge existing holes in a door

I know you'll all just say why doesn't he just buy a smaller lock..not an option..partner wants one of the existing locks on that door..it is a long story..
so is there a way to enlarge this hole???

Answer 1

Locks require 2 hole sizes. Older locks used a 1 5/8" hole, and newer locks use 21/8". Schlage deadbolts fill both sizes. I'm not sure why you don't to change lock types, but his would be the cheapest route. My lock installation jig cost around $800, a replacement lock would cost around $30.

Answer 2

Use your hole saw to cut out a plug from a scrap piece of wood.
Install the plug in the hole with masking tape wrapped around it to take up the slack caused by the blade.
Put enough tape so that it will fit tight.
Re drill the hole for the lock using the new template supplied with the new lock.

Answer 3

Some of these ideas are worth more then the money, very spendy. For you. I would cover the area with a piece of plywood and stain it to ft the color of the door, make a new hole over the old one, simple, I've done it, you don't need a $185.00 Porter cable set up.
Then put a brass plate over that to make it look good.

Answer 4

Depends on how deep the hole saw is compared to how thick the door is. Generally, you drill through one side until the mandrel bit comes out the other side. Then you drill from that side until the hole is complete. The reason you do this is to reduce the amount of wood tearout that happens when the drill bit emerges through the skin of the door.

Answer 5

a Porter-Cable 511 Cylindrical Lock Installation Kit.

it is $185.00 well worth the money - or call around and see if anyone rents a Lock Boring Jig.

this is what you need to save the door

Answer 6

yes, making sure you center lines are line up, use a 1x ( pine ) clamped over the hole and re drill with the bigger holesaw
the 1x will prevent the bit from walking since once you drill thru that it will guide it thru the door and prevent it from walking on you

Answer 7

To cut opening for lock in door jam there's a tool they call router cut (It is mill Handy machine deep and clean cut.)

Answer 8

some will wedge a block of wood into the hole then start over.. some will clamp wood over the hole...make sure they have their center line right. i have an older version of this
