Softwood is most commonly found in the regions of the world with lower temperatures and is typically less durable, lighter in weight, and more vulnerable to pests and fungal attacks in comparison to hardwoods. They typically have a paler color and a more open grain than hardwoods, which contributes to the tendency of felled softwood to shrink and swell as it dries. Softwoods usually have a lower density, around 25-37lb/cu ft, which can compromise its strength. Density, however, does vary within both softwoods and hardwoods depending on the wood's geographical origin and growth rate. However, the lower density of softwoods also allows it to have a greater strength with lighter weight. In the United States, softwoods are typically cheaper and more readily available and accessible. Most softwoods are suitable for general construction, especially framing, trim, and finish work, and carcassing.
Not happy with the selection of sanding blocks at the hardware store, I made a few of my own from hardwood scraps left over from a woodworking project. I cut each one to 3/4 in. x 1-1/2 in. x 4-1/2 in.—which is just the right size to wrap a quarter sheet of sandpaper around. And the “kerf” cut helps hold the sandpaper in place until I’m ready to change it. —Tim Olaerts. Here are 41 more genius sanding tips you need to know.
