I didn't want to hijack the most used tools thread, so here we go: This is about the machine that you use the least. I have lots of tools that haven't been used for many years, and some that will never be used again. A prime example would be a few purpose built wrenches I inherited from my wife's grandpa. Heirlooms. But not what this thread is about.

In the early 2000's I had the hots for a small shaper. I got a 7" Atlas, and fixed it up. I used it some, until I got a Bridgeport. Alot less after that. Then I got a Sheldon horizontal mill, And used the shaper even less. It's pretty, and not in my way so it will stay in the shop.

So what do all do use the least? and, why?
