"Anyone have experience with grinding sparks. Anyone had a problem?
Ah, sparks starting fires Gary. I've seen it. Different situation, but it's certainly possible. A classic case from many years ago at a place I worked involved a bench joiner thinking the horizontal belt sanding machine was a great tool for regrinding his plane blades. It did do a good job I suppose, but then the fire alarm located in the dust shed went off as the dust/ chip bins caught alight. Mass evacuation of about 200 staff from the whole complex of offices, joiners, glass workers and metal bashers as the company fire marshals tackled the blaze and the fire service rushed to our site. Needless to say, that particular joiner wasn't so highly thought of after that, ha, ha. Slainte.
