Silver Maple questions
How much does silver maple move with the seasons?
A 12″-wide flatsawn silver maple board moves about 3/16″ across a typical indoor swing from 6% to 12% moisture content; quartersawn, about 1/16″. Its tangential shrinkage is 7.2% and radial 3% (green to ovendry) — a moderate-movement wood.
How hard is silver maple?
Silver Maple rates about 700 lbf on the Janka scale — softer than red oak but sturdy (red oak is roughly 1,290 lbf). Density runs about 33 lb/ft³ at indoor moisture levels.
Is silver maple good for wide panels and tabletops?
Carefully. Its tangential-to-radial ratio of 2.4:1 makes flatsawn boards prone to cupping — choose quartersawn stock for wide glue-ups, alternate growth rings, and fasten tops so they can slide.
