Frank,
You're quite right there...but mostly to untrained thoughtless users. I started on a 10" Delta Unisaw at 14, now operating a 12"/3hp Wadkin clone for the last 30 years (I'm 69 now...) AND I've still got all 10...but seriously, very sharp blades and the knowledge of what's being cut and how to feed it and the sound of the cut will keep you on the 'right' side of safe...and I paint the table insert red so the brain automatically knows it's the danger zone. Now those pesky angle grinders, can't live with them or without them! I've seen WAY to many homemade 'attachments' for them that are flat out dangerous, particularly putting saw blades rated up to 6000 rpm, when the grinder goes to 11,000! On a recent stay in the ED at hospital, I asked an ambo about tradie accidents and he said, far and away the most common, was hand held circular saw cuts to arms and legs. Stay safe, even just for Mrs Frank! Cheers
