Hi. I’m struggling with the angle for bed molding that is wrapping the tops of some exterior soffit brackets/corbels. In my first mock up, I simply back cut the top corner of the corbel so that it formed a 90 degree angle with the raked soffit. Then I installed the bed mounding in a normal way. The problem is, the projection on the high side looks shallow and awkward. In the second 2 photos, you’ll see that I messed around with the angles, settling on a 46 degree miter with a 10 degree bevel for the front. The return is a 46 degree miter with a -1 degree bevel. I also back cut the meters with a utility knife. The result was less than perfect and I sanded them together. They will be installed 25 feet up the front of the exterior and painted so it’s all pretty forgiving. I guess I’m wondering- does the projection on the high side look proportionally correct on the 2nd mockup? And also- what am I missing about this concept? I couldn’t find anything online for this particular situation even though many old houses have this style of roofline trim. Thanks.

Take a look at this:

Later today I’ll look for an example of rake trimming and hope to post a picture. Tell me this....
Is the angle that your trim sits the same? It looks more flat against the frieze bd.
Thanks for the reply. That's a good article. It actually confirms what I suspected (assuming I'm understanding it at first glance)- that one will either need to create a second custom profile to extend the projection on the face, or one will have to use seat cuts, plumb cuts etc to get the mouldings to match.
As for the bed moulding in my 1st mockup- where it's sitting at the intersection of soffit and frieze....I disassembled the first mockup so I can't reference it. But it could be in a slightly more vertical orientation. The moulding that is already installed on the building sits at a variety of angles as needed. It's an old house and many surfaces are cupped etc. Fortunately the paint scheme is white on white. Additionally, I'm pretty good at coping inside corners and it's high enough off the ground that none of that variance registers to the eye. I also realize that my moulding on the low side of the corbels in both mockups leans out further that the normal projection of the bed moulding (which is about an inch). That's just the result of cutting and installing it as a normal 45 degree miter. Honestly, It doesn't bother me. I've seen it done different ways on different buildings around here, and usually looks fine regardless. It's the high side that looks too wimpy to my eye if it doesn't project properly.
Now here’s an interesting job I didn’t do.
That certainly looks like it had its share of challenges
