Domestic Mahogony Plywood 1/8X4X8 45*

American-made structural aircraft-grade plywood is made of imported African Mahogony veneers laminated in a hot press to hardwood cores of Poplar or Bass wood with waterproof glue. Will meet all requirements of specification MIL-P-6070, which calls for shear testing after immersion in boiling water for 3 hours. Far superior to many plywoods in which all plies are 1/16 inch thick and laminated in a cold press to make up the total thickness. Tests should be made on cold press plywoods before use on aerobatic aircraft. Available in 45° and 90°

Attention
90° 2' x 4' Plywood are cut with grain.
If cross cut required, specify at time of order

Q+A

What does the designation 90 degree or 45 degree refer to on the domestic mahogany plywood?
It is in reference to the grain direction. 90* material, the grain runs from left to right, parallel to the 8' edges. 45* material, the grain runs 45* from 8' edge, some describe it as the grain running from corner to opposite corner in a 4' x 4' section.
