I had an ERC bow go into deflex after sinew and I think it was due to moisture being absorbed by the dry wood and swelling the cells on the back but not the belly. I waited a while to see what it would do and it did start to regain reflex as it cured. I then tied it into reflex to help it along. Still have it-one of my favorites.

Did you size the back of the bow before sinewing? Besides helping with adhesion it also keep moisture transfer down, i pull mine into reflex and then sinew, then after it dries i pull it into more reflex and add sinew
failure is an option, everyone fails, it's how you handle it that matters.

Good point Bubby,
I did size it but may not have waited long before starting sinew. Can't remember for sure but that's probably the case. It was early in my sinew attempts. I do like you now and pull some reflex before starting sinew.

I guess what I did not understand from the opening post, is that you are sinewing the core before adding the bamboo belly?

so the idea of pulling  the bow into reflex while sinewing, I guess, is to make the sinew work harder to get to brace. I can see that as being a good thing because sinew can stretch a lot and take it.

But do you really want to wait until the bow has a lot of reflex before you add the bamboo? wouldn't that make the boo take set sooner?
or is there a plan to perhaps put it on a caul in some deflex, or at least, less reflex, to do the final glue up the boo belly?

No not looking for any reflex yet just noticed it deflexed but that is actually clearing up already starting to straighten out. Figure I'd put a layer down get the bamboo glue it up after it cures reverse string and add two more layers for a total of three.

I've done the same thing you are doing except I glued my bamboo on and tillered the bow to about 80%, then glued on three thin lifts of sinew with it tied into a shallow reflex. As it dried and pulled the string loose I just tightened it to hold the reflex.

Okay so did you tiller the back then ?

Yes, that's why only 80% give or take. Tillered the back till I thought my luck was running out. If you put too much bamboo on you are stuck with the poundage you end up with. Also, if you put too much sinew on it can overpower and cause the bamboo to fail. Put a lift on, let it cure and see what you have before you put another one on. The longer the sinew cures the stronger the bow gets, also.
