I found a block of solid metal the other day. Of course I put it in my bag to investigate later. Well it turns out to be rather unusual, it's aluminum, a full 0.5" thick, 4.5" long, 3" wide, with one hole through it. Scratched up like a bunch of cars have driven over it, but that's just surface damage.
What do I want this for? Well, I have no idea. But I'm sure I'll use it, probably make something interesting out of it Possibly even a bike part.
