First, the proper lumber is selected for superior qualities such as grade, texture, and color consistency. Then, all the boards are surfaced to a hit and miss thickness on a Newman-Whitney EPR-24 Planer. This operation virtually eliminates cup and minor surface checking. The boards are then scanned for width and defect optimization by a Grecon Dimter Scanner and then gang-ripped on a Raimann Moving Blade Rip Saw.

Next, the boards are optimized for length and precision double end trimmed on a Grecon Dimter Opticut 350 Optimizing Saw System.

Finally, the boards are run through a Weinig outboard bearing high-speed molder that gives the finest molded S4S finish available on the market today.

Appalachian produces S4S products from most of the species we carry, although some are manufactured on a custom-order basis. Below is a list of our in-stock items in Red Oak and Poplar.
