Before I tear it all out and start over.
I am finishing built-in bookcases in the corners of my living room. I have built up a series of moldings to be concluded with a 3″ (inside measure) ogee crown molding. I built a jig to be sure I started the moldings at the right height so when it came time to install the crown molding, it would fit sweet. IT WORKED. But – I calculated everything with the molding unside down.
The molding is a standard 52/38 d molding. The cut I am attempting is for an outside corner (45d). With the spring angle at 52d. my trig tells me I need a miter cut of 68.2d and a bevel of 42.5d. Of course, my SCMS (Makita) won’t do that. Is there another answer? My upside-down molding ceiling measure is 2 7/16″ (the run), the wall measure is 1 3/4″ (the rise) and the molding itself measures 3″.
Before I start ripping it all down and starting over, I thought I would inquire here. Thanks for any help.
Is it a fact that the wall measure must be longer than the ceiling measure?

Morning,
Build a wooden box and hand cut or set-up your SCMS to what ever up/down(vert.rise) and out (horz.run) dimensions you want and cut it. You will probably have to re-cut the angle on the back, in order to fit tight at the cabinet. This can easily be hand planed. If it is going to be painted, just caulk the small gap,you will probably caulk anyway.
Remember, upside down and backwards. Your fence is the wall(vert./up/down/rise) and your platform is the ceiling(horz./out/run).
I would cope the inside corner(OH,BOY!-hot topic lately),but your choice.
GOOD LUCK,
DAVE
Never tear down today, what you can tear down tomorrow.
Thanks all. I thought I was limited by the angles on my SCMS and I am not. If I insist on cutting the molding flat I am, however, if I cut the molding using the traditional 45d miter cut (upside down....etc.) I can salvage the job. Thanks.
If you are going to put the molding upside down on the project to stay with your layout, cut the molding right side up.Beat it to fit / Paint it to match
