I was discussing this problem with my friend.
(as far as engineering and design, I have just one :-)
He suggested this...

Fold the metal over a board, eg, a 2x4, so there is a
square channel. Special tools might be needed, but
maybe not.
Then take this upside-down U which is about 9" deep,
1.5" wide, and 12-24" long....
and raise the sides back up.
The folded edges become the shoulders of
your channel...and the valley forms by itself.
AUTO-MAGICALLY
Nail it down to the sleepers.

The width of the wood is calculated...
1/2 circumference + 1 diameter...
Pi*D/2 + D = 1.5 D + D = 2.5D
5/8 * 2.5 = 10/8 + 5/16 = 25/16 = 1.5"

Note, other than seeing it done as a test,
I have not done this yet...
but I expect to soon.

Sadly, the only reason I am trying is...
Radiantec is back ordered and I need them soon.

I got flashing for $32/50' - bought 3.
I also got new tinsnips that are optimized for straight.

I used a couple of short 2x4 as "wheel chocks"
so the roll of material does not get away from me.
(Trust me, it's worth wearing gloves :-)
