Peter expressed precisely :
I'm trying to run a dado rail on a wall going up a set of stairs and
then along a landing.

I can't work out how to cut the joint where the horizontal (landing)
run meets the stair wall run. Am I right in my guess that you set the
internal angle on a sliding bevel, measure it with a protractor, and
then halve it to get the right saw cut on both pieces?

Do it the way I did it....

Hold the horizontal section in place on the wall and mark pencil lines
either side of it. Do the same with the bit which runs down the stair.
Where the lines intersect for each of the upper and lower pencil
lines, draw a line through them with a straight edge. Lay each piece
back on the wall in turn and transfer the line onto each piece and
cut.


Or, if using a mitre saw, work out the angle between the two sections and
halve it. For example, if the stair angle is 40 degrees, the included angle
will be (180 - 40) = 140, and you will need to set the saw at 70 degrees.
