Shop notes The Southern outdoor wood — old-growth heartwood shrugs off rot. Works easily; smells faintly sour at the saw.

Baldcypress questions
How much does baldcypress move with the seasons?
A 12″-wide flatsawn baldcypress board moves about 5/32″ across a typical indoor swing from 6% to 12% moisture content; quartersawn, about 3/32″. Its tangential shrinkage is 6.2% and radial 3.8% (green to ovendry) — a moderate-movement wood.
How hard is baldcypress?
Baldcypress rates about 510 lbf on the Janka scale — soft enough to dent in daily use (red oak is roughly 1,290 lbf). Density runs about 32 lb/ft³ at indoor moisture levels.
Is baldcypress good for wide panels and tabletops?
Yes, with normal precautions: its 1.6:1 tangential-to-radial ratio is moderate. Still fasten solid tops so they can move across their width.
