Wood Species: Antique Heart Pine (Pinus spp.)
Appearance: Top portion is finished with water-base finish; bottom with oil-based finish.
Color: Heartwood is yellow after cutting & turns deep pinkish tan to warm reddish brown within weeks due to high resin content. Sapwood remains yellow, with occasional blue-black sap stain.
Grain: Dense, with high figuring. Plainsawn is swirled; rift- or quartersawn is primarily pinstriped. Curly or burl grain is rare.
Variations Within Species And Grades: Moderate color variation.
Workability:
- Sawing/Machining: Good machining and hand-tooling qualities.
- Sanding: Tendency to clog paper due to high resin content; Abrasives will need to be changed frequently during sanding. Beginning with a coarse grade is recommended.
- Nailing: No known problems.
- Finishing: May be difficult to stain. To reduce the wood’s tendency to repel finish coats, surface resins may be removed with a 100% pure (not recycled) solvent that is compatibel with the finish to be used. Do not use water.
Comments Origin: North America. Often recovered from structural timers in pre-1900 warehouses & factories, or as sunken logs from river bottoms.
Properties: Hardness/Janka: Janka:1225; (5% softer than Northern red oak).
Dimensional Stability: Values can vary greatly due to the variety of species and ages used.
