I've asked questions before about routers and had some very useful
responses
which I shall peruse again on google.

This is a rather specific question:

I need to rebate a load of architrave so it sits cleanly over the plaster
which is higher in places than the door frame, and also sits tight to the
door frame. I can caulk between the architrave and wall but not between
the
architrave and the frame as the wood's on show. Need to rebate between
2-5mm or so over about a 40-50mm width (sounds like several passes).

I would put it through my table saw, do you have access to one?
