Dear Ken,The decision is a bit tricky because you have two opposing issues. On one hand you want to insulate the movement of the solid from the every which way movement of the veneer, so it would be best to put a sub veneer between the face veneer and solid. On the other hand, veneer is usually run the same direction as the solid so they can expand and contract together, since you cant stop the movement of the solid anyway. With a burl this becomes a problem. I would say, that if the solid is fairly narrow go ahead and put down a backer veneer because the solid won't move all that much so it isnt going to blow the veneer off. On your panels, which will be wider, why don't you use a mdf since I assume it will be framed with solid.On other point, even burl has a grain direction if you look carefully. Sometimes depending on the burl I would run it with the grain direction the same as the solid. On your other piece that you had the problem, if I understand it correctly, the veneer was perpendicular to the solid. Thats the main problem.SincerelyDarryl Keil: Hello again Daryll,: I'm sure grateful for your time and willingness to share your : expertise. Thanks.: When using burl veneer over solid, i.e. maple burl over cherry : solids, am I safer using two ply in order to insulate the solid : movement from the "who knows what direction" movement of the burl? I : am building a tall clock and plan to veneer the stile and rail of the : door(2" wide max.). Given my recent experience with the short grain : banding on a desk top (where, because of the curving substrate, the : grain movement constantly changed directions) I'm a little concerned : about mixing solids with unpredictable veneer movement direction. : We'll also be using the burl on some panels for the base of the : clock. I have your formula for flattening the veneer which I plan to : use, then apply cross grain to a plain maple veneer for the two ply : and apply to bending ply substrate with balance plys on the back. : Make sense? Any other precautions with burls?: Thanks for your input.
