The feet aren't just aesthetic, in this case they were necessary. Unfortunately I chose to make this butcher block during a period of rapid weather change in San Francisco. In just one week the weather changed from cold, dry and wintery weather to warm, somewhat humid, spring weather - with several days of heavy rain thrown in for good measure.
I can only assume all these atmospheric hijinks wreaked havoc with this project. I started out with what seemed like very straight lumber, but after it was cut and glued, to my dismay the entire butcher block curled up like a potato chip (okay, slight exaggeration - but that's how it felt). The opposite corners on both sides of the board were twisted between 1/16" - 1/8" high, making the board rock from side to side.
With some serious hand-planing and sanding, I was able to get the board mostly flat, but I was worried it might not stay that way forever - especially since the customer will be taking it home to a very different climate. By adding some adjustable feet, I hope to future-proof this butcher block, allowing each foot to be adjusted to compensate for any future (hopefully small) warping.
