I hadn’t brought along my balalaika because I knew it annoyed Dustin, and it was unlikely that the four “Martian” humans would care for it. (Most of the actual Martians seemed indifferent to music; it was background noise to them, neither pleasant nor unpleasant.) But I hadn’t thought about all the room in the warehouse, where the four workers had lived before we arrived. It was a little cold, but large and totally isolated from our own living quarters. You could back up your balalaika with a brass band, and no one could hear you.

So I set out to make a thing like a balalaika. I could have just described it to the automatic shop machine, but there was no satisfaction in that.

No wood around to work with except the blocks of koa I brought for carving, so I asked the machine what it could simulate. My balalaika at home was made of rosewood, light and dark, and ebony. I found a picture of myself playing it, and so was able to measure it precisely from the image. I found instructions for making your own balalaika in Russian, no problem.

The three strings were easy, carbon fiber and nylon wires. The “wood” had the right color and density but wouldn’t fool a termite. The thinnest stock it could generate was two or three times too thick. So my first order of business was to take a strip of it and see whether I could plane it down.

No luck. No fibrous structure, so the hand plane would just bite out a chip at a time. But I blocked it in place and used a sander to bring it down to two millimeters’ thickness. It was still strong and stiff; I clamped it to the edge of the worktable and plucked it, and it made a satisfying twang.

I experimented with scrap and decided to forego tradition and cut the “wood” by laser, which left a more accurate, smooth edge than any saw in the shop. And with modern glues, I didn’t have to improvise the elaborate clamps that the Russian plans called for. I also cheated on the tuning pegs, bridge, and tailpiece, by describing them and letting the shop turn them out robotically. So it only took a couple of days, and a lot of that was learning. If I wanted to put together another one, I could probably do it in an afternoon. Give it to Dustin, so we could do duets.

It looked identical to mine at home except for the inlaid red star and “Souvenir of Soviet Olympics 1980,” which made mine a fairly valuable antique, in spite of being very ordinary in a musical way. A gift to my father on his tenth birthday. His parents had gone to the Olympics before he was born.
