It’s a little trickier than it looks because bamboo may look round, but it’s really not. I needed to hollow out a lip on the top and bottom to accept a glued in lid on the bottom. The top has a cap with a tennon which fits snuggly into place. The top is a little oversized to make up for the oval shaped bamboo, but I’m going to go a little smaller next time.
It’s a CA finish, but with CA being so darn hard and the out-of-roundness causing the sandpaper to rhythmically bounce off the walls, it’s not as smooth as I’d like. Next time I’ll probably try some wipe on polyurethane. Anyhow, it was a cool experiment and I’m sure I can improve on the idea.
