I visited the shed again with more tool donations a while back, while i was there an old boy was using a table saw, no crown guard or riving knife & the bit of wood kept riding up, how he never had a kickback i dont know. I had a word with the guy that runs the shed & he had not realised, he is well meaning but was over ridden by two old guys from industry who "Are qualified wood machinists & they say we dont need those bits as they get in the way etc etc", so they had removed all the guarding. I pointed out to my friend that when someone chops off his fingers he as organiser & the committee are liable as they allowed it to happen.
I think it sunk in, & sincerely hope nobody has been hurt.
