Cut off a 21-in.-long board for the shelves, rip it in the middle to make two shelves, and cut 45-degree bevels on the two long front edges with a router or table saw. Bevel the ends of the other board, cut dadoes, which are grooves cut into the wood with a router or a table saw with a dado blade, cross- wise (cut a dado on scrap and test-fit the shelves first!) and cut it into four narrower boards, two at 1-3/8 in. wide and two at 4 in.
With two varieties, red and white, oak is known to be easy to work with and relatively strong. However, furniture makers often opt for white oak over red oak for its attractive figure and moisture-resistance. Depending on the kind needed, oak can probably be found at a local home center or a lumberyard for a bit pricier than other hardwoods.
Some tools required to build a picture frame are a table saw, miter saw, measuring tape, wood glue etc. A table saw with a backing board and miter gauge can be used to get the right angle and lengths of picture frame every time. You can use builders square to arrange the final cut pieces before nailing, screwing or gluing. Check out the video tutorial below for more details.
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
How do you divide 11-3/8-in. (or any other mathematically difficult number) into equal parts without dividing fractions? Simple. Angle your tape across the workpiece until it reads an easily-divisible dimension and make your marks with the tape angled. For example, say you want to divide an 11-3/8-in. board into three equal parts. Angle the tape until it reads 12-in., and then make marks at “4” and “8”. Plus: More measuring tips and tricks.
