I doubt it’s crushing the ERC as the failures seem to be in tension under the sinew. I did 3 courses of sinew with at most 3 total oz. I floor tillered it good before sinew. Maybe I rounded a back a little too much before sinew?

Ya it’s hard to say really.  I don’t thing a rounded back would be a problem with sinew.  I find with sinew on these types of bows they crown a bit anyway.  I think is just the wood then that’s found a weak spot.  I think I’d be putting some ca glue to it and moving forward to see.  The reflex isn’t that extreme either so should be fine.  You had it bending good before sinew so any issues with the wood would have popped up prior most likley.
