Let me start with the goal...
I want to end up with flat smooth shiny veneered panel.
The veneer will be on a stable base.
Most likely with solid wood edging attached to the base first, then vacuum-bag glueing the veneer to the base material and edging.
Then some combo of either a Maloof (linseed+tung) with lacquer over it, or just a lacquer
I was leaning towards a belt sander with 240 or 300+ belts and then some 600 on a random orbital.
I am wondering if I would be better off using a plane or scraper to get the surface smooth and flat.
The edging also is producing some beard-stroking as I am concerned it mad want to pull away from the base with humidity/temp expansion and contraction.
I am considering the edging to be 10-12 mm wide and biscuited onto the substraight, before levelling it to be even with the surface... Then veneer.
How would a smart or wise person go about it?
