newel post install

[macliam88]

My next DIY project is replacing naff cheap late 70s horizontal bannisters for new traditional spindle handrail version

You can see the bottom of the stairs and stringer in picture 1 and the newly post I'm getting in picture 2.

From the various videos I have watched on the topic I am thinking (if you look at picture 3) that I cut the stringer back to where the green dotted line is roughly plus a small notch out of the last step as also shown and that the new newel slots in in blue mark drawn. Is that that right way to go about it?

Also is adhesive and long wood screws into the stringer enough to secure or should there be some sort of floor fastener too in the concrete sub floor?

Would appreciate a steer

Yes you are correct, and yes once the newel is tightly fitted with glue and screws it wont be going anywhere, as the handrail traps it in place to stop any wobble at the top.

Thanks @Jord86

Can I follow up with a couple questions on fixings?

1. do you need to bother necessarily with the fancy handrail connectors like zipbolt etc or is wood glue plus 150mm timber fixing screws like Timco enough?
2. any preference on the glue for the newel post to stringer?

Do it properly and mortice and tenon

1. No fancy connector nonsense, either mortise and tenon as ginger tuffs says as it is traditional and the best, or pilot drill and screw, either a couple of 3” screws from underneath at an angle or a 5” screw through the newel into the handrail on the level.
2. If your mortise is tight and good, PVA, if it’s a bit loose and gappy then use an expanding PU glue such as Gator glue, D4, Egger, anything that bubbles up and expands really.

you may need a newel stub for the newel to fix too saddling the string
and remember the newel must be central on the string for it to work
