I found some rare-earth magnets! Woo-hoo!

If you have some old PC hard drives sitting around and don't mind doing a little demolition, there's two very powerful magnets used for head positioning in each drive. They're mounted on a threaded piece of steel that's in the shape of an arc (at least the ones I've been scavenging) and have raised several blood blisters already.

But they ARE cheap!

Bill,

Put on safety glasses and try to slide them apart. Be careful. Those little magnets can be nasty. If they collide from a very short distance they can shatter with a spray of very sharp shards. They can also deliver a nasty pinch if your skin gets between them. I was showing someone how they are strong enough to stick on either side of my finger. Well, one slipped to the side and took a 1/4" piece of skin off my finger. It bled profusely. It really hurt when my friend wouldn't stop laughing.

These are actually "better" than regular rare earth - MUCH stronger!
Very fast shipping - to Oz at least

Heh-he-heh! Some of those are strong enough you'ld just about hurt yourself getting them apart.

My thanks to Scottydont (fka scott) for the rare-earth magnet idea to mount my dust hood to my lathe.

I found some in my hobby room that I'm almost sure are rare-earth magnets. My question is, how do you get them apart once you get a N and a S all snuggled up to each other?
