yeah! We all hear the safety phrases, be sure to read and understand all the safety instructions from the manufacturer....... and so on. Familiarity breeds contempt so we tend to gloss over the safety rules as we become familiar with the way we do things in the shop and don't think too hard about what can happen and how fast it can happen. AFTER I CHANGED MY UNDERWARE! soon after I saw this YOU TUBE video I thought others of us might benefit from a safety re-think as I did. The video author is lucky, just plain lucky!!! even though he went into this with his eyes wide open.
