Hi Red.
Since posting this I have spent a couple of days at The Derby Hand Clinic having my fingers debrided after a circular saw accident.
A word of warning. If you have a fluorescent lamp over a table saw the stroboscopic effect of these lamps can make the blade look still. I turned it off and went to remove some plastic that had split to find the blade still running-down.
