The care and labor required to cut and to select Comb Grain Oak raises its value, and so it should be specified with consideration for the need and overall value to the project. Rotary Slicing – cutting Rotary veneer is similar to pulling paper towels off a roll. Rotary fine hardwoods are used in a limited way in architectural woodworking. This edition of the QSI restricts the use of Rotary veneers (unless specified otherwise) to Custom and Economy Grades. It’s probably not necessary to mention, but solid lumber can’t be produced in a Rotary manner. Rotary slicing is a lot like lumber from the viewpoint that “matching” of rotary panels Figure 200-14, page 240, Quality Standards Illustrated is just about as difficult as “matching” from one board to another. When Rotary is used in fine woodworking, it is almost always for the special effect the wild grain patterns can bring to the job. The wild figure, particularly in species which have visual contrasts between the earlywood and the latewood, is a function of the rotary cutting process. pattern seems to Matching of rise or fall from grain or figure panel-to-panel in from panel to sequential order. panel is unlikely, Book matchbecause logs ing is usually used aren’t always with Plain Sliced perfectly round, veneers.

Once we have a stack of veneer leaves sliced, we have to arrange them side-by-side to form the faces we discussed at the start of the article.
