Certi-Sawn Tapersawn Shakes
These shakes are sawn both sides. Premium and Number 1 Grades are the
most common. Premium Grade is 100% edge grain, 100% clear and 100%
heartwood. Number 1 Grade allows up to 20% flat grain in each bundle.
Number 2 and 3 Grades are also available.
These shakes have split faces and sawn backs. Cedar logs are first cut into
desired lengths. Blanks or boards of proper thickness are split and then run
diagonally through a bandsaw to produce two tapered shakes from each
blank. Available in Premium Grade (100% edge grain) or Number 1 Grade
(Up to 20% flat grain allowed in each bundle).
Produced by hand, using a sharp bladed steel froe and a mallet. The natural
shingle-like taper is achieved by reversing the block, end-for-end, with each
split. Premium Grade only.
Produced by machine or in the same manner as tapersplit shakes except
that by splitting from the same end of the block, the shakes acquire the
same thickness throughout. Premium Grade only.
