I have a large shed with 6" x 3" timber uprights resting on a stub
block wall. The bottom 2-3 feet of the posts is rotten so I want to
splice-in some new timber. I can't think how to cut a decent lap joint
in the bottom end of the remaining upright so I'm tempted to butt join
the timber and add steel plates (fish plates?) on each side - at a
guess these would be around 150 wide 450 long and a few mm thick.

Suggestions welcomed for how to cut a lap joint on the bottom of a bit
of timber that's waggling in the breeze, or for a source of suitable
steel plates.

Bit of care with a decent handsaw? 3" with a jigsaw is tricky.

I would strengthen by screwing on some 25x50mm folded galvanised steel
(because I have some:-) but 1"x2" angle would do. Use two lengths per
join.

Alternatively the agricultural approach... butt join and then strengthen
by nailing on 3"x2" either side:-)

Makes more sense to replace it entirely and use an acrow prop to keep
the roof up while replacing it.

Fair point, provided there is not too much disruption or other carpentry
required. Devil in the details, as ever.

Yeah, I guess the external cladding could well be nailed to it and it might
well be quite a bit of effort to get that off and back on the new one.
