One of the misconceptions about planers is that they make lumber straight. They do some straightening, but they don’t make lumber straight. That is what jointers do. Many lumber mills just send rough lumber through the planer allowing the board to exit the machine with the same ups and downs and whoops that is entered with, only now to a consistent thickness. This is especially apparent when gluing up a couple of these roller coaster type of boards and trying to get them to line up. After a couple of those glue-ups, you will swear by lumber that has seen the jointer before the planer, and never skip the jointer.
Make sure to run ground wires wrapped around all lengths of flexible exhaust hose to prevent static build up, which can spark and potentially ignite. I chose the King 1.5 HP dust collector, with a 115 volt motor, so I did not need special wiring for it. A shop vac is a must, as well, used to vacuum out machinery, and to remove dust from furniture prior to finishing. Finally, an air filtration system was installed to clear the air of tiny airborne particles. The King KAC 650 unit I installed does a nice job, has a remote control, and a programmable delay – I usually have the air cleaner run for a timed two hours when I leave the shop.
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.
First, let’s take a look at four placement options for the table saw, the machine that is at the heart of most woodshops. The first option (see the illustration) places it in the center of the shop, which lends maximum space and flexibility for ripping and panel sawing, as well as crosscutting long boards. The main requirement here is a shop that’s at least long and wide enough to allow room for the workpiece, both on the infeed and outfeed sides.
