Many years ago I was given a box full of bar-ends from an engineering company. They range from 1/4" to 1" diameter and from 3" to 9" in length. Most are ordinary mild steel, but some are hard, probably EN16 or similar. Even though I use "known" material for important parts, there are many occasions when "any old bit of steel" will suffice. Hence this box full has been very useful over the years. Unfortunately during a house move (the one prior to the recent one), that box got put aside and filled with water. So, I have loads of rusty metal. Still comes in handy for the odd job. But, none that I have used before had this grain problem. Alan MODEL ENGINEERING DISCUSSION LIST.
