Good job Jeff, man you were quick! I just now saw this post and your already done with it....dang that's fast.
I prepped my boo the exact same way you did, and I saw some similarities the way we do other things too. Like the sawzall blade on the back of the surfaces to be glued. I think this is probably why some guys glue ups fail, they are afraid to groove the back of their material to be glued up. I gouge mine pretty good, but not super deep to cause failure, but I want nice channels for the glue to penetrate and have something to grab onto.
Great Job overall man, and I hope you get a nice bird with it this spring. I'm getting back to work on mine today. Hopefully be shootin some arras by this afternoon.
