increasing letter box aperture

[timbalcombe]

Hi,

Went to fit a new stormguard internal/external letterplate (keep out those draughts!) and found that the hole is too small.
What would be the best way of opening this up?
Its a wooden door approx 2" thick.
Sleeve is about 2" too long each side.

There is many ways you can do this, the best and most effective is to use a router if you have one, first clamping 2x1 to the door to act as your guide/stops, use several cuts only taking out a max of 5mm at a time. Alternatively you could drill the four corners and cut between them with a jigsaw, remembering to cut so the rough edge is on the outside, therefore covered by the letter plate, if you do not make as tidy a job as you would have liked you can cover the rear with a draught flap!
