Puzzled about roof spars - Do you round the edges?

[mikeschn]

For those of you with too much time on your hands, how about making up some mini truss joists from plywood - about 1 1/2" deep? Lightweight, wide fastening flange, resistant to bowing or warping. What's not to like other than the PITA to make all of these.

Similar to these mini trusses that I did for a chassis design. But you certainly don't want to build that. Can you imagine what happens to OSB when it gets wet?

I rounded the bottom edges of the trusses, just to make it look a bit better. No need to round off the top, listen to what Mike said, he hit the nail right on the head.
