Balsa
Balsa is the world's lightest commercial wood — technically a hardwood despite being softer than most softwoods. 'Balsa' is Spanish for 'raft,' which gives you a clue about its best quality: extraordinary buoyancy and lightness. For model making, carving, composite cores, and any application where weight matters above all else, nothing else competes. Don't knock it for being soft — it's perfect for what it does.
- Using dull tools — balsa cuts beautifully with sharp tools and makes a fuzzy, torn mess with dull ones
- Skipping a sealer coat before finishing — balsa is so porous it can absorb enormous amounts of finish before building
- Trying to hold it with nails or screws — always glue balsa; fasteners have essentially no holding power in this wood
Sapwood (which is what is sold commercially) is white to off-white or tan, sometimes with a pink or yellow hue. True heartwood is pale reddish brown but rarely seen.
The easiest wood to work that exists — cuts like firm cheese. Dull cutters produce fuzzy surfaces, so keep tools sharp. Glue is preferred over nails (too soft to hold fasteners). Stains and finishes well but soaks up considerable material on initial coats; seal first.
