Hi all
1970s dump in the 7th year of restoration :(. The staircase has a 180 degree return at an intermediate landing. SWMBO wants an upgrade to the ranch style 70s look bannister. With discussions between me, her and the builder I believe we've settled on white oak spindles and handrailing in between the existing painted newel posts. Bit of a compromise, but avoids removal/cutting of newel posts and she wants plain square newels rather than turned ones anyway.Issue is that the existing intermediate newel post on the int. landing is not tall enough! It accepts the existing ranch fencing OK, but this does not conform to current regs. I know I can ignore this at my peril, but want to know whether extending the post is possible.
The current post is 90mm square and I would want to add 4-6" - the top is currently chamfered toward the corners IYSWIM.
My concerns are: Cutting the top of the existing post off square in the first place Sourcing additional timber that will not shrink by 1/4" across flats after fitting Making an invisible joint between existing and new sections (invisible after painting) that will withstand the usual high loads imposed by teenagers decending at break-kneck speed. Re-creating the chamfer on the new post top.
Any advice appreciated
TIA
Phil
