Nathan - Yeah, I saw that.  No problem.  Just knowing the product exists is enough!  Thanks again.

Ron - For next time, I think I'd CNC 2-3 plywood collars to go around the staves and use wedges between the collar and staves to press the staves towards the center.  

Steve - I've been pondering that glue-up for a while.   I'm glad it's behind me.
