Cutting for Keyhole Liner
So, I'm building a cabinet and mortising in a lock for the doors. What I'm struggling with is cutting the keyhole. I want to use a Keyhole Liner insert but am not sure what the best way to go about cutting the opening is and still having the insert fit snugly in the hole. I suppose a "keyhole saw" would do the trick but wanted to get feedback from the folks on here to see how best to accomplish this.
Or is it better to use an escutcheon and just forget about making the cut look nice.
p.s. i don't want to risk free handing a router using a keyhole bit. I'd lose my effing mind if I ruined these doors and drawers at the 11th hour.
