Thanks Flinttim. I've never glued one up all by myself. I was Will Steffen's demos for a couple of years at Mojam, and I've had him make me a couple more years ago with wood I sent him. I bought the pieces I have now from Mike back in 2005 with the intention of making some sort of form and doing it myself, then a move due to work put the kibosh on that. I remember how Will's form was nice as it was very adjustable, I just can't remember the basic starting points as far as measurements go.
