Cherry : Heartwood is a light pinkish brown when freshly cut, darkening to a medium reddish brown with time and upon exposure to light. Sapwood is a pale yellowish color. Cherry is known as being one of the best all-around woods for workability. It is stable, straight-grained, and machines well. The only difficulties typically arise if the wood is being stained, as it can sometimes give blotchy results—using a sanding sealer prior to staining, or using a gel-based stain is recommended.
Maple : Fairly easy to work with both hand and machine tools, though slightly more difficult than soft maple due to hard maple’s higher density. Maple has a tendency to burn when being machined with high-speed cutters such as in a router. Turns, glues, and finishes well, though blotches can occur when staining, and a pre-conditioner, gel stain, or toner may be necessary to get an even color.
Walnut : Typically easy to work provided the grain is straight and regular. Planer tearout can sometimes be a problem when surfacing pieces with irregular or figured grain. Glues, stains, and finishes well, (though walnut is rarely stained). Responds well to steam bending.
