 In this way the log is peeled into sheets of veneer, which are then cut to the desired oversize dimensions, to allow it to shrink (depending on wood species) when dried.The sheets are then patched, graded, glued together and then baked in a press at a temperature of at least , and at a pressure of up to (but more commonly 200 psi) to form the plywood panel.The panel can then be patched, have minor surface defects such as splits or small knot holes filled, re-sized, sanded or otherwise refinished, depending on the market for which it is intended.
