Sugar Pine questions

How much does sugar pine move with the seasons?

A 12″-wide flatsawn sugar pine board moves about 5/32″ across a typical indoor swing from 6% to 12% moisture content; quartersawn, about 1/16″. Its tangential shrinkage is 5.6% and radial 2.9% (green to ovendry) — a low-movement wood.

How hard is sugar pine?

Sugar Pine rates about 380 lbf on the Janka scale — soft enough to dent in daily use (red oak is roughly 1,290 lbf). Density runs about 25 lb/ft³ at indoor moisture levels.

Is sugar pine good for wide panels and tabletops?

Yes, with normal precautions: its 1.9:1 tangential-to-radial ratio is moderate. Still fasten solid tops so they can move across their width.
