Damian Lakatos, Johnstown, Penn.: “I use an old Mason jar as a ‘spark guard’ to contain the sparks on my bench grinder. I didn’t want the sparks bouncing off my shop wall and back at me, and I was also worried they could start a fire.
“The jar captures the sparks surprisingly well, with very few misses, and the glass handles the heat with no problem. I plan to apply 1/2-in. weather stripping onto the jar’s sides to keep it from rolling around.”
