How would I measure how to cut the panel pieces that will go under the slanted ceiling where my stairs go above my living room wall? In the picture shows the paneling I am doing but I’m unsure how to measure the angle needed for each piece going along the left side of the wall under my staircase. Thank you!
To determine the angle you can use an angle finder or you can use couple pieces of scrap if you have it, hold one piece plumb and take another piece of scrap and hold it up to the angled portion, over the top of your vertical piece and scribe your vertical piece with a pencil. This will provide the exact angle of your cut.
Once you get to the angled portion, measure to the long point of the angle and make your cut at the angle you determined earlier.
To calculate the height of your next board, measure to the short point of your angle of the board you just cut, subtract whatever you would like for the spacing and that will be the long point measurement of your next board.
