tricky exterior crown cuts

[mcsquared]

Question for you. I have two 12 pitch gable roofs at right angles to eachother on the corner of the house. The crown wants to come down the rake and return back up the other gable rake. The crown sits at a 45 degree angle but the problem is finding the cuts to make that a nice corner cut.

His explanation/description is fairly straightforward. He's describing a gabled roof, with a reverse gable roof intersecting perfectly at a corner. There are no eaves: only rakes.

I can give him the fascia cuts: 12/12, mark the plumb cut and set the bevel on a 45. That will tie the fascia and/or frieze together but that doesn't answer the crown question.

The profile: that's a mystery at this point.

Yeah. the fascia was what you say and that was easy enough but the crown I don't think can be cut on a miter box. The spring angle of the crown is 45 degree and its a 5 1/2 crown. So far with trial and error im looking at about a 10 degree miter and around a 55 degree bevel but i dont know.

Also just sign up and ill be working on the profile

Make a jig that swings the cut as narrow as you need it. I make a jig/sled for every crown profile I ever cut. When I'm done I tape a piece of the crown to it so I can quickly know what crown it is to. If you just make a wedge to back that up you can swing any angle, and if you are using a 12" SCMS you should have no problem. The alternative would be trial and error cutting the piece flat and adjusting the bevel and angle.
Jim says the gable rakes meet at the lower point, but I didn't get that from what you posted. I thought you meant that there was a slight inside corner to the soffit between the reverse gable.

Maybe I'm missing something, but you should be able to cut this crown standing up in the saw. Could you set the crown up against the fence (right side up, it's going up a rake not level on a wall), set the saw angle at 45 deg for the plumb cut and bevel at 45 deg to get it around the corner? You should be able to cut it the same you did for the fascia you must just account for how the moulding projects.

I see a lot of guys vaselating trying to find compound angles for gable crown so they can cut it flat. It's a waste of time in my opinion. Cut it like it sits on the gable (opposite of how it sits on a wall.)

How'd it work?
