Begin by cutting off a 10-in. length of the board and setting it aside. Rip the remaining 38-in. board to 6 in. wide and cut five evenly spaced saw kerfs 5/8 in. deep along one face. Crosscut the slotted board into four 9-in. pieces and glue them into a block, being careful not to slop glue into the saw kerfs (you can clean them out with a knife before the glue dries). Saw a 15-degree angle on one end and screw the plywood piece under the angled end of the block.
For many of us, the moment we learned that a 2×4 board is actually 1.5 inches x 3.5 inches was simply mind-blowing. The reason for this apparent contradiction is that the board has been planed down to eliminate irregularities. At one point, many years ago, 2x4s actually were 2 inches x 4 inches, but their rough surfaces made them difficult to stock and handle. The old terms, such as 2×4 or 4×4, are still used, and are known as the “nominal” size of the board. These nominal sizes are used because they are easier to say and they stick to tradition. Now, thanks to a lawsuit, most big box stores list the nominal and actual sizes of lumber.
Historically, woodworkers relied upon the woods native to their region, until transportation and trade innovations made more exotic woods available to the craftsman. Woods are typically sorted into three basic types: hardwoods typified by tight grain and derived from broadleaf trees, softwoods from coniferous trees, and man-made materials such as plywood and MDF.

Sanding the inside of a hole or curved surface can be difficult. To simplify that task, insert a 1/4 x 3-in. bolt into the pilot hole of a hole-saw cutout. Secure the bolt with a washer and nut. Using a hacksaw, cut a 1/4-in. deep slot in line with the bolt. Cut a piece of adhesive-backed sandpaper so that you can slide one end into the slot, wrap it around the cutout, and slide the other end back into the slot. Chuck the bolt into a drill, and you now have a homemade drum sander. — E.R. Comstock. How to Sand Wood Faster
Hardwoods are separated into two categories, temperate and tropical hardwoods, depending on their origin. Temperate hardwoods are found in the regions between the tropics and poles, and are of particular interest to wood workers for their cost-effective aesthetic appeal and sustainable sources. Tropical hardwoods are found within the equatorial belt, including Africa, Asia, and South America. Hardwoods flaunt a higher density, around 65lb/cu ft as a result of slower growing rates and is more stable when drying. As a result of its high density, hardwoods are typically heavier than softwoods but can also be more brittle. While there are an abundant number of hardwood species, only 200 are common enough and pliable enough to be used for woodworking. Hardwoods have a wide variety of properties, making it easy to find a hardwood to suit nearly any purpose, but they are especially suitable for outdoor use due to their strength and resilience to rot and decay. The coloring of hardwoods ranges from light to very dark, making it especially versatile for aesthetic purposes. However, because hardwoods are more closely grained, they are typically harder to work than softwoods. They are also harder to acquire in the United States and, as a result, are more expensive.
This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood
Here’s a nifty tip—with a nifty tip—from faithful reader Don Ayers: Fill snap-capped sports water bottles with glue and stick them upside down in a hunk of 2×6. Now you don’t have to wait for the glue to run into the neck of the bottle, and the cap will control glue flow (and never get lost!). To holster the glue dispensers, cut holes in the base with a spade bit that’s a smidgen larger than the cap’s diameter.
