i bought a ryobi radial arm saw back in the eightys. it was small 81/4 i think. i got a letter saying "STOP using your ra200 radial arm saw and return it immediately" apparently some of them broke and caused injury. when it came back it didnt look like anything was done to it. none of the screws looked like they were taken apart, no tool marks on the hardware so i never used it again.
