I would like to replace my stair hand rails (pine to oak), but I do not want to go to the bother (and expense) of changing the upright posts (newel posts) as I intend to paint them. The existing hand rails are attached to the newel posts by mortise and tenon, the only way to get them out is to cut through at the intersections - but then I have a problem attaching the new rails to the posts - I can't use mortise and tenon as there is no room to manoeuvre the joints into position. So I guess I could use screws at an angle from underneath but I am not sure how secure this solution would be. Maybe I could somehow use a peg from underneath or perhaps there are some brackets available! Two of the longer handrails are horizon (on the landing) but I have another 5 shorter rails which are angled downwards along the turn of the stairs. I would be grateful for any advice please. Thanks
