View Full Version : Controlling cast iron dust

There was a thread a while back about the dust from machining cast iron being bad for machines. I was thinking about that today as I was getting ready to turn a piece on my lathe. I wrapped a magnet inside a piece of paper towel, and positioned it close to the tool bit with the magnetic base for the dial indicator.

The magnet caught most of the dust, and the paper towel made disposal easy. It might not work for large jobs, and it might not catch all the bad stuff, but it's a step in the right direction. I followed it up with a vacuum cleaner and wipe down.

Putting it in a sandwich bag works good too.

I also cover the ways and crevices with paper towels or polycloths too.

It's hard to beat a shop vac for collecting cast iton dust and chips as they're generated.

Use a drywall bag in the vac.

I build a rigid but easily adjusted sucker right over the tool whose capture zone is centered on the chips.

Remember to empty the vac frequently of you're makeinglots of chips. 12 gallons of cast iron chips gets pretty heavy.
