Weldo commented on our “Hot or Not? Metal Chop Saws For Home Shop Use” post — where I lamented how the mess they make keeps me from having one in the shop — with a kick-ass solution:

I keep some paperboard (like what cereal boxes are made of) over a set of welding magnets behind them to catch the debris.  That way you just peel off the paperboard and let the filings fall into the trash.

Why didn’t I think of that?  Awesome, and I’m totally going to try it.

    That’s a fantastic idea for chopping anything iron based. Any ideas for my aluminum mess?

    That’s brilliant! I’m going to try that with my bench grinder and maybe the drill press too.

    And a good source for magnets: Whenever you install new speakers in a car, gut the old ones. They’re huge, yes, but in this application, I’m thinking more square footage is better, right?

    Hmm…. Paperboard in close proximity to a spark source? Am I the only one seeing a potential issue here?

    About grinding aluminum: be careful and remove all traces of aluminum before cutting steel. You might produce combustible thermite, which is powdered aluminum and iron oxide, and is used as a source of intense heat to weld high strength materials.
