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.

Dont even startt. Do waht I did. Enormous tub of car body filler
moulded to upright shape...use bit of timeber to bulk it if you must.



Thanks, but I'd like some strength in the post, rather than just
having it look OK



Oh FFS its STRONGER than wood!




It's not the strength of the material that counts, it is the strength of
the connections. I agree, you could mould it round some studding let
into the wood.
