This bar rail moulding has two sets of measurements, the milling dimension is 5-29/32" wide by 1-3/4" thickness, it will require eight quarter lumber to mill this pattern properly, the installed dimension is roughly 5-7/8" wide by 2-13/16" tall. The profile design is composed of a series of tangent radius's rolling downward like a wave, this provides a smooth and comfortable area for you to rest your arms on while enjoying your favorite cocktail . The backside is rabbeted by the sizes that are listed on the image, it is rabbeted for the subtop and the countertop. This will be an expensive moulding to purchase, the reason is, it utilizes four profiling stations on a moulder with larges cuts on each spindle, moulding knife cost will definitely escalate production cost. The downloadable dxf file includes all four profile cuts needed to successfully produce this pattern, the bar rail is designed on the same plane so holding down the wood whole milling and blending the profiles together will be a breeze for any moulding machine operator.
