Screws, bolts, nails, and…

I spent a couple of hours sitting around today.

Now before everyone falls off their chairs, no, I wasn’t joining mainstream television watching culture and, no, I wasn’t having a well-earned rest either.

No, I was carrying out a vital job that’s much akin to standing on the end of a railway station platform and deciding if it was a modified Class 37 locomotive in the yard or an unmodified one.
