Having just thoroughly cleaned my lathe after machining some cast iron, I was sorry to find that I had a little more of the same stuff to machine. To prevent it from messing up my nice clean lathe, I held a magnet, enclosed in a plastic bag, near the tool. Result, a small bag of iron dust ready for disposal! I can't believe I haven't done it before! I intend to make a dedicated fixture with a magnetic base, for future use. I am now searching eBay for a brass magnet!

Yes Maurice, a magnet in a plastic bag reduces the mess you get when machining cast iron. A magnet (in a plastic bag) on a stick is aslo useful to fetch those small screws and nuts I tend to drop into a crevice.
Let us know when you find a brass magnet.

Doh! = the Oh b****r of previous years. I've just been machining cast iron and now my carpet tiles are a lighter shade of grey. If you know Procul Harum's song I'll allow one run through the chorus.

So where to buy a few magnets then?

PS: Keeping the job wet stops the dust but then it gets messy to clear the sludge. Don't you just love working with cast?

Errrr. No….too messy……the cuttings get everywhere……!

I recently completed a cross slide project for the Mini lathe. ( thank you Neil.. ). And the dust/ debris that created was horrendous…… ( sneezing black dust for a while ….can't be good ! )

You can with advantage set up a vacuum cleaner nozzle nearby and suck the dust off the tooling as it arises.

If I did that, I would probably be looking for new accommodation (+ a new Wife).

Upside down tool on the far side(like a parting tool). Use the backgear. Total Doddle.

Iron filings form a eat pile on the far side of the lathe

Sook up the mess with a vacuum

I use a welding magnet- they can be bought with an on/off switch. Makes disposing of the stuff much easier, also any stray nuts etc. will be spotted before being lost forever.

Just be careful of which type of vacuum cleaner you use, if it's a cylinder type, and the bag leaks, the cast iron goes through the motor, and this rather annoys the brushes and commutator, so they usually give up with a Bang.

Breathing cast iron and carbon dust reminds Me of a long ago apprenticeship. Not all bad as it's what started Me on a machinist bend with a shop full of tools.
