Do you have a full sized saw?
I would glue/attach all of the boards on one side extending past the other side. Once dry, sand or trim to the 60° or whatever angle that allows the other side to be but jointed without sanding. Does that make sense? That way your only sanding 1 set of angles vs 2.
Then glue attach the 2nd board over the top of the first making an overlapping angle. Then trim that one as needed.
Only a full size hand saw, Craig.
I was quite happy with what I had before meeting you guys.
This is the full extent of my wood shop, power tools.
But it’s cedar planks. Easy to sand.
I’d glue one side up completely over extended past the other side. Then using the sander sand at the full angle (60°) vs the 30. Then run the next over the top without cutting. Then repeat. Instead of trying to get 2 30° to match you basically gluing on a flat. I don’t know if that makes sense how I’m writing it.
or you could do, what the 1:1 guys would do.
take some metal sheets and nail them on top of whatever you made.
I love “roof lines”… However I’m staying on topic as recommended!
“All ridge caps are easy”
YES they are…
It’s just a matter how far beyond the ridge cap you wish to go? I personally you’re ,your, UR structure is "screaming " for a copper ridge cap with an iron cresting above it . Call it “cottage victorian”
JMHO

Craig,
Love the idea of the overlap but with my fiddley little planks it was hard to not over do by hand and lining up over the gap was difficult.
However, I am saving your idea for a big board sub roofing as it makes sense and I think it will save time. Thanks!
So I’ve made the job a bit tougher for myself and hinged two planks with scotch tape. I seem to be able to get a decent line. So I will try to work from the Center out and glue both sides and the join under the tape at the same time🤞
I am not looking forward to this without a pin nailer.
EDIT: Pin nailer ordered tonight from the USA $158 vs if I got it here $589 USD.
@Korm & @Rooster I can’t find my fake copper anymore. Is this what you’re talking about?
Copper 
the rim in my pic was cut from the bottom of an (oneway) aliminium foil baking form.
silverish looking duct-tape would fill the role too.
Are you up early AGAIN Korm?
It’s 0530!
yup.
just finished the first cup of coffee, after i dried up part of a lovely rain, that entered the house.
70mm/nearly 3" - about a tentht of the yearly rainfall, is what i slept through between midnight and 0500!
And here it is 3:50 
19:27 here! What’s going on with you guys?!
Are you guys on a paper route?
define, what that expression means.
i stand up every morning at 0500. and go to bed between 0000 and 0400 - but i take at least two longer daily siestas - during the hot daylight hours.
It’s usually the time a young man would get up, and start delivering the morning newspaper to houses around the neighbourhood throwing them from his bicycle. He’d have a route to follow.
My hours have gotten strange as I age. currently I get up between 1AM and 5AM
thanks, understood.
i just imagine myself on a bike, with a laptop taped to the handlebar - throwing papers against peoples doors… 
does that coincide with the most common times for fire alerts in your town?
Sounds like a good time to consider world travelling eastward with a rail pass . It’s mid morning in Europe right now!
To do it properly, each resident should receive their paper in the bushes or the roof. 
THAT would be one boring ride!
there are neither mountains, woods, nor stations between Boston and Dublin.
but he could ride on Chris Walas’ underseatrain.
now you’ll have to excuse me.
i’m off to my 26,297th breakfast.
