making the best of things...

Rough wood lids provide contrasting texture.
As I was working on boxes to illustrate proportion, I made the sidewalls of trays too thick, so I made thinner ones and turned the first trays into boxes. These you can see in the photo above. The lids are made with rough sawn wood, still marked by the large blade that ripped it into lumber years ago. I used a wire brush to remove loose material and fuzz. Then I sanded it lightly with 320 grit sand paper, just to make it comfortable to the touch. As usual, these small boxes will be pretty (or at least interesting and useful) when they are sanded and the Danish oil is applied.

I've been making many more boxes than normal. Last September, Crystal Bridges Museum asked me if I would make 300 boxes to serve as thank you gifts for their first year staff. Those had to be completed for distribution at the first anniversary party in November. When the museum founder heard about the boxes, she asked that I make another 500 boxes to give to their first year volunteers. Those I delivered in mid December. Now that the museum has had plenty of time to put 800 boxes into the hands of first year staff and volunteers, I no longer have to keep this box making extravaganza a secret.

The boxes were made with woods harvested on the museum site during the first phase of construction, so each box has a special connection with the museum grounds. I served as a volunteer consultant when the woods were first first processed from logs to lumber, so it was a particularly meaningful thing for me to have the opportunity to make boxes from those woods.

 In any case, I am now having some difficulty not making boxes in larger than normal numbers and my wife is wondering what we'll do with all of them.

I also started the 4th project for my new book, this one illustrating contrast through making a small series of bracelet boxes. Each will be different. The primary box in the chapter is walnut and the corners are secured by hidden splines that will be visible only when the hinged lid is opened. These new boxes are made to be glued up two at a time.

I learned that my Master Class making wooden hinges for Fine Woodworking is scheduled for issue number 234, which should come out in July.

This is spring break for the Clear Spring School, so I am getting just a bit of extra time in my own wood shop.

plus or minus two

Box makers often have difficulty deciding on the proportion to make a box. I'm always aiming toward simplification, in the hopes of removing gumption traps. I want to make things as easy for you as they've become for me through my years of work. Of course the easiest way to make a box with matching grain at the corners is to make a square box. But what if square bores you? What next?

I offer a simple design rule that can be used for making most rectangular boxes, unless there is something special that must fit inside. In honor of cognitive psychologist George Miller who passed away at the age of 92 last July, we can call it plus or minus 2. Miller had written a paper, on the Magical Number Seven, Plus or Minus Two, and whether or not you consider Miller's theory as valid, my own design rule might seem more familiar. A whole set of common proportions are based on this rule which to my knowledge has never been outlined or used as I will present.

3 x 5... 4 x 6... 5 x 7... 6 x 8... 7 x 9... 8 x 10... Are any of these pairs of numbers familiar to you? Some are the common sizes that you can have photographic prints made, and if you want to go buy a picture frame at Michael's to put your picture in, these are the sizes you will find. They just also happen to be handy proportions for box making. And if you look closely, you will see that they follow the rule that if one side is x, the other will be x plus or minus 2.

There may be a simple explanation for all this having to do with the sizes of paper easily cut from larger sizes. Or are there magical qualities to objects designed according to these proportions? In any case, a two inch spacer block works great when making a rectangular box. Put it in place for cutting the short side and then remove it for cutting the long. In other words, you can set up your stop block on the miter sled and make a box and have opposite sides fit perfectly, cutting them one after the other consecutively from the stock
