Working on 100 year old victorian reno/ addition built by someone else who tried to match original house rake and fascia details which has a wide crown running down the rakes and along the fascia with little pigeon roofs as well on the underside of the rakes.
My problem is trying to line up the crown profiles on the outside corners. On the lower 5 pitch roofs after alot of experimenting with compound mitres I got it to look pretty good but right before T-day I started on the 12 pitch and it seems like its next to impossible to get them close. I looked at what the prior carpenter did and its not even close and looks like sh-t
Anyone got any advice to speed up this cut and cut again? This is a cost plus job and I dont want HO to think I am milking it plus I have to start other jobs so any advice is appreciated except for tying the airhose around my neck and jumping from the staging

Normally, when the rake and fascia crown meet, two similar but different crown profiles are used. I've seen this transistion made by changing the pitch of the rake crown (laying it flatter against the fascia) when the same profile is used. The other alternatives are using a wedge of crown to make the transistion or a retuen with a little roof to land the rake crown on.
You either need to change the spring angle of the crown on the fascia or change the profile of the rake crown.
Years ago, when FHB had more useful info. there was an article about this, with all the geometry explained.
But alas, those days are gone now....
The simplest way to understand is to think of it as a simple outside corner tilted up to whatever roof pitch you have.
The eave piece has to rotate forward so the spring angle from plumb becomes the original sring angle PLUS the roof pitch.
On a steeper roof this can make the crown look almost flat on the eaves, so they (Archys or some other sadists) started using two different profiles.
This is because when you compound miter a section it will elongate the section.
I found it!!!

I can't afford to be affordable anymore
never had to find a back issue and i dont have that one how do i find it?
This issue got a little water on it. Page 2 - I need to reduce in size a little.
