Factors in choosing materials
There are many factors to consider when deciding what type of wood to use for a project. One of the most important is the workability of the wood: the way in which it responds when worked by hand or tools, the quality of the grain, and how it responds to adhesives and finishes.[9] When the workability of wood is high, it offers a lower resistance when cutting and has a diminished blunting effect on tools.[9] Highly workable wood is easier to manipulate into desired forms. If the wood grain is straight and even, it will be much easier to create strong and durable glued joints. Additionally, it will help protect the wood from splitting when nailed or screwed.[9] Coarse grains require a lengthy process of filing and rubbing down the grain to produce a smooth result.[9]
Another important factor to be considered is the durability of the wood, especially in regards to moisture. If the finished project will be exposed to moisture (e.g. outdoor projects) or high humidity or condensation (e.g. in kitchens or bathrooms), then the wood needs to be especially durable in order to prevent rot. Because of their oily qualities, many tropical hardwoods such as teak and mahogany are popular for such applications.[9]
