Well, the easiest way to do it would have been to grab a short
length of log, and use it as a hub, with sockets cut into
it to take the ends of the rafters.

Well, the compound mitre saw will do the job, but it's not
necessary. If you set a circular saw to 45 degrees, and
just cut along the 4:12 slope line on both sides, that
should do it. Or, since this is after all, a shed,
not a piano, you could cut the 4:12 line flat, and
use a chisel, axe, or router to bevel the ends.
Trying to do fiddly end-cuts like that with a handsaw
is a good way (IMNSHO) to scrape up your knuckles.
Personally, if you've already got the
right-angle parts up, I'd be tempted to fill in the
corners with angle-blocks, glued and screwed
into place. That would give you a flat spot
instead of a point to butt the rafter in.
