Compound miter cut trim question

robosapien

I was replacing window trim and I cut a piece to run the width of the window underneath the sill and cut a 45 degree bevel and a 22.5 degree miter so that I could cut small pieces to put on the ends so the profile would turn towards the wall instead of just having the end grain be the ends. The problem is I cannot figure out for the life of me how to cut those small end pieces to stick in the corners. \_____/ thats the shape and there is a 45 degree back cut on both ends which I cant illustrate with back and forward slashes. Any thoughts?

Did you mean to have typed those in reverse order? The miter that returns to the wall is usually a simple 45. (half of the 90 degree turn)

And usually, that is the only cut they get........ the shape of the molding profile will give you a slight angle on each end.

hey robo,
pretend the ends of your apron (the trim under the stool/sill) is being mitered around two outside corners.

what you should have is a 45 on either end of the apron, and then a little tiny "return" piece with a 45 miter and the other end of that butts to to the wall.
unless the apron is a profiled piece, though, typically it is just end grain.

the piece will be extremely small and will probably go flying off the saw. just cut it slow and keep an eye on it.

I let off the saw trigger when the cut is just about finished and let the blade finish the cut as it slows to a stop. It won't fling the little piece then.
