Magnetic lathe chucks

I'm wondering from those who have them, the pros and cons of magnetic lathe chucks.

They don't seem very common. I first saw one used by YouTuber Stefan Gotteswinter.

I'd think swarf would cling to them something awful and hinder their use?
 
I don't have one, but have seen them on cylindrical grinders. That's going back over thirty years since I worked in that shop.

Swarf wouldn't be an issue if you just used them on aluminum.



Just kidding!

Ha ha you got me!

I did think about that and then realized some of the places I think I would want the features of a magnetic chuck may very well be with aluminum or brass projects.

In the meantime I think I will make an adjustable chuck spider for my 3 jaw.
 
The problem with the magnetic chuck is that you would need a large area of "sticking" on order to make sure part does not move - and even then any work would have to be very "delicate". On the other hand, you could work with flat sock that otherwise is hard to hold on a lathe. Niche application.

Oh ya and if you haven't seen Stefan Gotteswinter video where he is testing out his shop made tool post grinder here is the link.https://youtu.be/znTTiDv02GM
He uses a magnetic chuck near the end of the video to hold a small bearing race.
 
where do you get a magnetic chuck? A few searches kbc, shars, aliexpress, nothing.
 
I bought mine out of the UK from a supplier. It is offshore made, but was cheaper than I could buy off Ebay and Amazon at the time. The shipping was super cheap too.

It is a 6" one, wit pretty good holding power. I found another way to do the job it was intended for, soi it sits...
