Longleaf Pine
Old-growth longleaf pine — sold as 'heart pine' — built much of the American South and is one of the most historically significant American woods. The extreme resin content of old-growth heartwood makes it nearly indestructible; beams from 19th-century buildings are harder than most modern hardwoods. Reclaimed heart pine is a completely different material from plantation-grown longleaf: darker, harder, more stable, and dramatically more resinous. If you have the chance to work reclaimed material, do it.
- Assuming plantation longleaf has the same hardness and durability as old-growth — it's significantly softer and less resinous
- Gluing resinous surfaces without first wiping with acetone or naphtha — the oils prevent adhesion
- Underestimating how hard old-growth material is; it will dull blades quickly and require carbide
Old-growth heartwood is deep amber to orange-brown, darkening richly with age. New-growth is much paler and lighter. Sapwood is pale cream-yellow and broad in young plantation trees.
Old-growth is surprisingly hard for a softwood — harder than many domestic hardwoods — and the high resin content dulls tools quickly. New-growth works like a typical dense pine. Gluing resinous surfaces requires solvent prep. Oil and varnish finishes work well; water-based finishes may bead on resinous areas.
