If you are talking about Canadian Western red cedar, than that is not bowwood. It's also not in the botanical genus Juniperus and therefore hardly related to ERC/Eastern red cedar. Any wood from the genus Juniperus will make a bow, but Western red cedar is not from that genus.
I have successfully made an English Longbow from a Western Red Cedar fence rail. 76" tip to tip, warbow dimensions in the handle area, so a full 1 1/4 inch wide grip area, roughly following the 5/8 rule, tiller is full circle and bending nicely thru the handle. There is a scant 1/4 inch creamy sapwood over the lovely dark heartwood.
It is fretted fully from one end to the other, as if an engineer distributed them according to the most careful measurements. It draws a little under 28 lbs at 30 inches draw. And it has taken about 5 inches of set.
So, yeah you CAN make a bow from it. But I think you could make a better bow of laminated used Post-It Notes and school paste.
