George Tsoukalas:
She is moving to the weak side, Pat, so give the other side a few scrapes and short draw it.

I had a yew stave that Jim Fetrow sent me years ago. You can imagine the angst I had in making sure it would become a bow.

I took pains, to the point of using a caliper, to make sure wood removal was even...left and right. Yet, when I strung it for the first time she was a leaner, favoring one side when braced.

I just took  few scrapes from the other side and fixed it relatively quickly.

I admit I don't have the patience to deal with that much reflex so good for you.

That sucks Pat.  I’m sure you’ll get it sorted.   I personally would just try to shorten it an inch then try again then a bit more if needed.  Sinew can do some interesting things when mated to wood bow.  It’s not the same as throwing a layer of fg on the back that’s for sure.  I’m sure your sinew job was consistent to the naked eye and done very well but I wonder if a variance in sinew thickness perhaps between the two levers you developed the hinge at was enough to cause it.  It was bending good prior to the sinew so my guess would be that a touch more sinew was applied to the stronger side.  Without seeing it it’s hard to know for sure but I’m sure you’ll get all good. I think you can salvage it like you say and shorten a bit and like jawge says to do a few scrapes after to get it in line.  Fingers crossed.  I hoping good things for this bow.  All the best!

Still watching and learning.

I've decided to go with a patch. I have a thin piece of osage but I didn't want the contrast and I think it would be too stiff. My next option was a thin piece of ERC but I didn't want to chance that. Then I picked up a piece of the elm from this bow, sawed a thin piece out and flattened and smoother it with the belt sander.
 My next decision was glue. Should I use some Unibond Roy sent me or TBIII. I went with the TBIII because I wanted to glue it up at room temp. I was afraid of introducing heat for curing with the hide glue/sinew backing.
 I ground the patch flat then ground the area to be patched making sure I took just enough off to get a flat surface and made sure the patch and patch area glue surfaces mated well. I buttered both glue surfaces with TBIII and with a stiff backing over the patch I clamped with spring clamps. I'll give it at least until tomorrow for the glue to set then I'll see what I've got. After that I'll re-shape the patched area and see if it worked.

Piddler:
Same comment as Selfbowman. Watching and Learning.
I'm quite sure you can make it happen Mr Pat.
