I have to admit that the joy of making something that works, no matter how small, is one of the reasons for me being in this hobby. The first thing I made, or rather two things because I can't remember which was first, was making a countersink and a 60° screwcutting tool from silver steel. Nothing much, I know, but from little acorns do big oak trees grow.
And recently, as of last Sunday, the lathe got me out of a hole. I dismantled a dripping tap to find that the washer was crumbling away so badly that it would not have worked if I put it back in the tap. Of course, Sod's Law intervened and the only spare washer I had was too big, and the local hardware shop was closed. So I mounted the overlarge washer in the lathe and turned it down. Job done.
Now I could not have done that before I got a lathe, well, not without a great deal of difficulty.
