Cleaning up old chisels

[George Pagliarulo]

I need to rejuvenate a number of chisels that have sat unused for many years. Most of them were my Dad's, he did his own grinding by eye and, honestly, he wasn't great at it. I don't know how he produced all the segmented bowls he did with the way these tools were ground but then he could make anything work.
Anyway, before I regrind the tools, some of them have some rust that I want to remove. I don't know what the metal is but I know its not carbide. Some of the tools are from an old Craftsman set and some are older Woodcraft chisels.
Is there anything I should be aware of, as far as using chemical rust remover, when cleaning the tools?
Thanks

here’s a good thread on rust, others available with the search mode: https://www.aawforum.org/community/threads/lathe-bed-rust.20764/

For the gouges I would polish the flutes with a sip stone to reopen any pits.
I do this occasionally on my gouges just so I’m grinding the cutting edge against a smooth surface.

I would try Sanding the tools with WD 40. This will get the tools smooth enough to slide well on the tool rest.

I would start with a wire wheel on a high speed grinder. This is what I do with old hand planes and plane irons. This makes it easier to see how much damage there is. Next steps can be emery paper and some WD 40 or other oils. It kind of depends....

Maybe more important than rust is what type of steel you've got. If it's not High Speed Steel, you'll have to be very careful when sharpening, and avoid bluing the steel. Essentially all turning tools sold new today are made from High Speed Steel, or some variations that are even more durable and tolerant of heat.

This is a great reason to connect with a mentor from your local woodturning club. Doing so can help you stay safe, and make gains in your turning skill at a dramatically faster rate than watching Youtube videos and learning on your own. You can find your local club on the AAW main website (woodturner.org, click on chapters, click on "Find a...")

Try Apple Cider Vinegar soak. Only do this about 30 minutes at a time as if left overnight there will be lots less steel there. I have not had any ill effects except that it can leave a dark patina on some steels. It sure beats all that scrubbing and wire brushing. You will need to wash off with soap and water . Oil the after you dry it off.
