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?
They're in the same plane ie not turning a corner...
TIA
