Wow, good eye. I cannot believe you spotted that with all of the clutter.
No real reason to have it, but it is handy for checking things before or after machining, or whatnot. The factory machine shop I used to work at had it. That placed closed last year and there were ALOT of things up for grabs that other plants did not want, all you had to do was request it. Things like nice wilton bench vise, hose real, electric cord reel, LED light real, old mag drill, puller set, Rockwell tester, to name a few.
Some of the pics you might be able to see the small steel rack with lots of round stock, pipe, and other short pieces. I made the rack while at work there, and got to take it home with me as well as everything on it when they closed. Not to mention the 45 or so 3ph electric motors that are under the white tarp that I have no clue what I am going to do with yet....
IT was a really good place to work, and they treated us real well when we left, cause everything I took, was just going to be thrown into a steel dumpster.
