I want to veneer 8" to 12" wide walnut, Is there an optimal size to buy ? 4/4, 8/4, 16/4.? Also I am looking at the grizzly 18" open end drum sander, but i want 1/16" finished veneers, specs show it can only sand to a minimum 1/8" , could i send it through on top of another board w/out having to use double sided tape? or is there a better way, or procedure? Thanks
