I am looking for advice and or solutions for a wooden chair seat that has a split of a previously glued butt joint. The split is actually wider on the under side of the seat, and is spilt from back to front with about an 1 1/2 inch glued together section in the front. It appears to be glued long grain to long grain, looks like a slight bevel of a 1/2 degree at the bottom of the split from the top. I tried to clamp the split together to see what I was dealing with and noticed the forementioned bevel, the joint would not close and left a 1/16th of an inch gap.

Any Ideas on how to fix the problem, short of resawing the joint and regluing.?
