Nothing yet.

In the process of moving from an apartment to a house, once I'm settled in I'll give it some more thought.

So far I looked around, it seems is a little painful with a press drill vs. a mill, but obviously even a cheap mill is pretty expensive. But it still looks doable.

As for anodizing, that apparently only requires a bucket, some acid and a battery charger. Doesn't look hard or expensive to do at all.
