Hello John, I really admire the way you've set about this project; considering all the various steps in advance, investing the time into making appropriate jigs, and carefully planning and practising the glue-up. You're a woodworker that deserves to do well.
My workshop isn't a million miles from you, where there's a 405mm planer and thicknesser, panel saw that can take full sheets of plywood, morticer, spindle moulder with power feed, bag press, and loads of other kit. Don't hesitate to let me know if I can ever be of any help with future projects.
