I have to wrap two half columns in veneer. The construction is a ply box 12'' deep by 60'' long by 4'' wide to which a half turned 4'' diameter white pine column is attached. I do not want to use anything other than a rigid glue line in a vacuum bag. Normally, I would run a cross band veneer perpendicular to the column, then veneer long grain with the long dimension of the column, but the 2'' radius is a bit tight to do. Can I get away with just running the vertical veneer without the backing, or will I end up with telegraphing and checking?
The pine half round is what concerns me! Any other wood might not be a problem. I would try wrapping a very thin veneer 1/42" or thinner to crossband and then glue up face with the grain running parallel to the joint. Use only urea glue for a rigid glue line.
