Veneer over mdf. I really like it Tony, so I don't wanna mess it up .
Since you can't see the ends you can't tell from that 2nd pic. If the ends show face grain then you know it's veneer, although with a burl it could be hard to tell even then. You'd have to examine it closely to see if the grain lines merge from face to side.I didn't realize it was veneer. Maybe @phinds can chime in.
Always the best ideaI have some scraps to experiment on
