Your Collections?

I collect unfinished projects. Some of them are hand made, meaning they weren't a project until I got a hold of them. :)

Every once in a while I ruin one of my unfinished projects by finishing it.
So I always keep a few extra on hand if this happens.

I have a stack of clocks that need repair, and a bunch of wrist watches mostly Bulova auto-winds from the 50's- 70's and a few accutrons.
A bunch of reloading presses and their accompanied equipment.
2 darts, and an extra drive-train that I have been working on since 1985. My wife still doesn't realize that this means that at some point I will need another car to put it in.
