What makes a good drawer?

Drawers are in our furniture and our cabinets. What makes some drawer work great, and others not so much? There are three things that effect drawer quality; materials, construction and sliding mechanisms.

Let’s start with materials. The highest quality drawer boxes are made from hardwoods such as maple. On high end work you may even find solid wood drawer bottoms, although veneers are the norm due to their strength and stability. One step down are boxes made from veneer plywood such as Baltic Birch. This type of plywood is not only is it strong, but the edges look good. The lowest quality drawers are made of some version of “twas” wood (thanks Walt). It twas wood, then it was ground up, mixed with glue and pressed into a board. This is the most likely to fail due to the lack of internal strength.

The next measure of drawer quality is construction. The best drawers will be assembled using dovetail joinery. It is strong and attractive, and when done well, they can’t fail. There are several methods of interlocking joints that work well but they are not as strong. The bottom of the barrel is a butt joint, two pieces of wood butt together. They are usually glued and nailed, but this is a very weak joint and usually doesn’t last. One more thing, the bottom should sit in a groove in the sides and drawer front, not just nailed on the bottom. Over time the weight of the items in the drawer will wear on the nails and eventually will cause the bottom to fall off.

A high end piece may work very well without any mechanical assistance but generally slides are required. It could be something simple like a wood on wood slide or a mechanical slide. These are generally used on dressers and larger drawer, so the need to stand up to a fair amount of wear and tear. Mechanical slides fall into two basic categories; rollers and ball bearings. Rollers are more popular due to their lower cost. Ball bearing slides are considerably stronger, smoother, and allow for over travel. Most drawers only open ¾ of the way making you reach in for items in the back. Over travel allows the back of the drawer to extend beyond the face frame.

Keep this information in mind the next time you buy a piece with a drawer in it, you’ll know what you’re getting into.

What do you need to know when buying a power tool?

Let me state that I’m not just a lifelong tool junkie; I also sold power tools for seven years. In those years I’ve trained with a lot of manufacturers and learned what makes a good tool, and what to avoid.

Rule #1: Buy the best tool you can afford. If you buy a cheap tool, odds are you’ll have to replace it faster than if you had bought a quality tool. That said; if it is something you will use once a year, you don’t need to get top of the line, just know what you getting into.

Rule #2: Make sure you compare apples to apples. A store brand 18v drill isn’t the same as one from a manufacturer like Makita or the like. Some manufacturers even make two grades of tools that look identical. They do this by exchanging bearings with nylon sleeves, and steel gears with aluminum or plastic. While the models make look the same, they will have a slightly different model number, and usually a significant price difference.

Rule #3 (and this is a personal one): Don’t buy store brand tools from big box stores. They tend to be less durable, less powerful, and harder to repair. Too many times I’ve met people who said “but they have a life time warranty” only to find out that the parts are not available, or they have to jump through hoops to get any satisfaction.

Rule #4: Do your research. Talk to contractors, go to a specialty tool store, or read woodworking magazines. Any good contractor will share their thoughts with you, and rarely will you find one of these stores that won’t help a weekend warrior. I’m a fan of books and magazines from The Taunton Press, who always have quality material.

Rule #5: Don’t get hung up on one manufacturer. Some people will only by DeWalt or Milwaukee, etc. There is a problem with this theory; every manufacturer has some great products, and some dogs (with the possible exception of Bosch). I believe that in the long run buying the best tool available is better than having a color coded tool chest.

OK, these may be the rantings of a tool junky, but I think if you use this information on your next tool purchase, you’ll end up with a tool that will last you a long time.
