My next step was to veneer the curved panels. From my experience using cauls to hold down the second layer of 1/4 wig wood ply, it seemed that a different clamping scheme would be required. the cauls I made just never appeared to deliver sufficient pressure at mid span, and no manner of wedging/tightening seemed to deliver this without causing a gap to form elsewhere.
I posed the question to woodcentral.com and the old salts there advised vacuum bagging. This made sense and so I grabbed a vacuum pump and bag assy from joe wood worker's website. I could have spent the time getting my own pump and bag setup done, but this guy's got the entire solution. www.joewoodworker.com
I'll begin with showing where I left off with the panels today, sanded to 180grit.
