Yes Bob . Iíve straightened and prepared the back without violating the back ring . Built a new caul with a tad more reflex. Prepared the bamboo and will glue it up sometime today.

Spent some hours on the heat bench and not finished yet.also I heat treated the back also prior to gluing bamboo on. DC did it on his laminates on his last build .  Thought I would try it on this one. Arvin

Bob the bow tested good . Short of Steveís record but may be a contender with the right conditions. 222 yds was best test shot. Just trying different  backs for simple composite class Arvin

 I was a little concerned that heat treating the back of the belly would affect the glue up but it didn't seem to harm it. I'll be watching, I've got a piece of Osage that I can't make a decision on.

The rings are real even but getting that back flat enough to not violate a growth ring took some doing with dry heat. Now if I can keep in one growth ring when tillering the belly. Arvin

that's pretty cool Arvin.  I don't think I have ever seen the horn on the back...usually it's on the belly.  Now, bamboo backed osage is a marriage made in heaven... :)

Seeing the picture of your edge grain reminds me of my favorite bamboo backed osage...but I used the most perfect edge grain osage I've ever seen for the belly slat.  It's the one I shot at MoJam.

Looking forward to seeing the finished bow and the stats on it's performance.    (SH)
