I remember when i started work ( just over thirty years ago ) in a joiners shop and we had a new 3 phase spindle moulder installed. the man that came to show us how to use it only had his little and ring fingers and nothing else till the lowest joint on what used to be his thumb on his left hand [eek]
because he was feeding timber through the moulder free hand and it pulled his hand in and shredded it , he said he didnt feel it at first as the ( 2 inch ) cutter was running at 30 thousand rpm and was so quick it wasnt until there was blood everywhere he realised it was his hand. Taught me from an early age to respect power tools in any form and although i have had a few minor mishaps and scars as a reminder i consider myself fortunate to have been fairly mishap free
