Stair Hand Rail on wall
I need to install a stair hand rail on a wall (the staircase has a wall up each side).
The stairs turn to the right 8 steps up,each step rise is 7 1/2" the tread is 10". At the 9th step the turn starts,the rise is 7 1/2".
The left side of the tread is 21 1/2".
The right side is 2". The 10th step rise is 7 1/2", the tread is 15" to the wall, 17" to the next step,and on right side is 2".the 11th is 21" on the left 2" on the right,with 7 1/2" rise.the last step is 10" tread with a 7 1/2" rise to the landing.
The stair case is 39" wide.I plan on putting the hand rail on the left since there's a switch on the right and a newel post at the top with a hand rail and balusters.The rail is to be at 34" high at the top of rail.
I will be putting a 3/4" x 4" oak board on the wall to attach the rail brackets.I need to know at what angle to cut and how many sections .
Also I"m wanting to avoid a compound cut in the corner.
