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.

A bit fiddly, but can't you make the basic cuts for a lap joint with
a circular saw? And square off with a panel saw. Then put coach bolts
through it.

Tough to do with the timber hanging down from the roof structure,
which it will be once I saw off the rotten bit. I suppose I could cut
a sort of half lap joint (zillions of half-depth cuts with a circ saw,
then cleaned-up with a chisel) while the rotten bit is still attached
and providing a little bit of anchorage, then saw off the end. Hmm,
perhaps I could first attach some sacrificial timber over the rot and
fix it to the wall to a provide temporary anchorage.

Sounds like a job for a multitool.

A bit slow, on 6 x 3.
