Meanwhile, back on thread...
I can see now that it's going to have to be a right-angle turn as I can't see any elegant/strong way to provide a quarter-circular support where I intended. The support can be easily fashioned..just that it will jut out and look strange.
I jacked up both the upper string and also used folding wedges to support the top of the lower string underneath. Who needs an Acrow prop, anyway ?
Cut a housing in the new 'external' newel post to take the top of the bottom flight stringer, made up some epoxy.
Clamped and screwed to the bottom of the upper flight stringer and inserted some 14mm Domino's.
It was somewhat reassuring to gently release the car jack and see the weight being safely taken on the new newel pot. All left to harden overnight. Current thoughts are to carve what's left of the old Newel D stub into something that looks like the end of the bottom tread.
This morning I had a good long hard look all the way round the remains of Newel D and as far as I could see, any fixings were largely cosmetic. So I set to with a chisel and carbide metal blades in the Fein.
and it wasn't long before I could feel the whole stub moving about and clearly not fulfilling any useful function. After 30 minutes or so satisfying 'demolition' the stub dropped out of the bottom with a thud....felt like I'd extracted a wisdom tooth.
Dead chuffed that I've got rid of two complete newel posts.
So now I've got to make good. This riser has seen better days and is twisted and split.
Although the bottom tread is housed in the stringer, I'll still support the bullnose. I'll jigsaw down the length of that riser and remove it. Conveniently the front of the new riser will sit over the extreme end of the boards on the quarter-landing and so if I put a rebate on the bottom of the new riser, it will hide the grotty ends of the boards.
The bullnose and adjacent tapered tread on the quarter-landing platform can be taken out and new ones made to extend all the way across. Just that I'm not sure now quite how to finish off that end by the new newel post to take the ends of these new treads.
Any suggestions, sketches gratefully received.
We're getting there and its looking much, much better than I could have hoped for IMO.
