That's a 10'-7 1/2" radius. How deep and thick is the timber?
I don't have any experience with that glue. We've used West System epoxy for all the curved glulams we've made. We didn't get much springback at all -- 1/2" or less.
You'll need to exert a lot of force to bend those 3/4" thick boards that much, especially if the beam is 8x8 or bigger. I would consider using 5/8" thick laminae.
