I hear you LBD. Ship it over and I'll give it a whirl. Ha! Not a bad idea with the screw clamp but too late. Mos, I've already glued up 5 layers of 3/4" ply with a 2" hole.  I'll be using the glued up block for attaching the first dowel to the base so it's serving two purposes. Used a hole saw and cut the squares a little over size. Then wrapped packing tape around a dowel end and used the dowel to keep the squares centered for glue up. Clamped that to my drill press vise. The clamp holds things securely.  I'll post up some pics.
