I am contemplating replacing my front door with a thicker one - which would require the rebate in the frame to be made wider.
Any clues as to how best to do this in situ?
I would have thought that something involving a router (rather than an angle grinder! ) might be appropriate - but what would be the best way to control the width of cut? Maybe a bearing-guided cutter running against a temporary batten or somesuch? However, a router wouldn't get very close to the corners. How should these be tackled?
TIA.
