I prefer a full face shield after the following incident, it saving my face from being ripped open and possibly an eye destroyed into the bargain.
Was using the Emco Star circular saw to cut 1/8 ply used for the tool drawers I was making.
My mistake was the fact that the machine was only 2" off the ground, thus when one strip of ply reached the end of the cut it jammed between saw and fence and was flung straight out and upwards, impacting the face shield.
That face shield has a dent to show the impact.
I still shudder thinking what could have happened, and not forgetting the time the blade had a go at the heel of my palm.
Geoff – The machine is now at a safer working height.
