Looking fine Ross!
I do like Nathan when cutting off excess veneer, For the end grain, a box cutter (Exacto for small stuff) from the veneer side on top and only pressing down with the blade at about a 45 to the surface and as close to the substrait edge as possible without shaving a corner. If i didn't biff it, I'll then use a sanding block down stroke only, to flush up the edge.
Long grain cutting really needs to go the direction of petting the cat. if the grain dives inward, chances are high of getting a really nasty crack running onto the panel.
If I can manipulate the panel on the TS, I'll tape the veneer and trim with the veneer on top, blade at max height for the downward cuts.
It is a tough choice between trim before or after. Before leaves a surface edge to edge veneer, but that edge can catch and chip. Trim after protects that edge, bit with the change in visuals.
