Sherwood Posted November 8, 2008 Report Share Posted November 8, 2008 How do these magnets get posted? Do they arrive in a crate 3 foot cubed lined with lead? Depends. If you buy two they deliver the first as described, and the second is simply dropped from altitude and expected to find its own way. Quote Link to comment Share on other sites More sharing options...

cclragnarok Posted November 8, 2008 Report Share Posted November 8, 2008 If you only bought 2, they would have 3 left, so I don't think this is gonna work. Somebody should make a compass out of these. Or maybe DIY speakers. Quote Link to comment Share on other sites More sharing options...
Chekhonte Posted November 8, 2008 Report Share Posted November 8, 2008 I ordered several large ones earlier this week, 3 inch diameter by 2 inches depth. I'll tell you when they arrive how they're packaged. Quote Link to comment Share on other sites More sharing options...
Duggeh Posted November 8, 2008 Report Share Posted November 8, 2008 No kidding, I don't like anything that can generate that much force that doesn't have a on-off switch. This is of course, the biggest factor, nay ultimately, the only factor, which induces the fear in such a material. It is the knowledge that control over its forces lies beyond the users power. It's like stting on a grenade thats had the pin pulled. Depends. If you buy two they deliver the first as described, and the second is simply dropped from altitude and expected to find its own way. *wile-E-coyote cliff noise* i hope the box is covered with random nails and forks and rusty birdcages. My vision is of the postman ringing the doorbell to get help prying the parcel off the inside of the van wall. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted November 8, 2008 Author Report Share Posted November 8, 2008 No kidding, I don't like anything that can generate that much force that doesn't have a on-off switch. You have no idea. My biggest superconducting magnet is about 12 times more powerful than that thing. And its gap is 3 feet long. if you want an isolation system that really works, you really need to go with a pneumatic system, or pneumatics and active piezoelectrics.

aerius Posted November 8, 2008 Report Share Posted November 8, 2008 How do these magnets get posted? Do they arrive in a crate 3 foot cubed lined with lead? I have a couple that are about the size of a hockey puck. The magnets were wrapped with foam then stuck to the inside of a steel box, which is wrapped with more foam & bubblewrap and put into yet another steel box. Which then gets stuffed into cardboard box for shipping. The cardboard box was around an 8" to 10" cube. Quote Link to comment Share on other sites More sharing options...
Chekhonte Posted November 8, 2008 Report Share Posted November 8, 2008 wow that's pretty amazing. I'm interesting in seeing if mine are shipped the same way. by the way aerius, may I ask what you are using the magnets for? Quote Link to comment Share on other sites More sharing options...
pabbi1 Posted November 8, 2008 Report Share Posted November 8, 2008 OH i have some delightfully evil people here. Aluminum or magnesium bowling ball. Painted black to look like the real thing. Take it to a bowling alley and try and use it... Annodize, not paint, in any number of colors. And, of course, laser scribed with evil runes to render curse on all who oppose you...

aerius Posted November 8, 2008 Report Share Posted November 8, 2008 by the way aerius, may I ask what you are using the magnets for? I use them to support the hanging hooks for my bikes so I don't have to drill the hooks into the wall. The magnets stick to the steel support beams behind the drywall of my apartment, and the hooks are welded onto a piece of steel that's stuck onto the magnet. Then the bikes just hang off the hooks.

Chekhonte Posted November 8, 2008 Report Share Posted November 8, 2008 quite ingenious! Quote Link to comment Share on other sites More sharing options...
aerius Posted November 8, 2008 Report Share Posted November 8, 2008 Though to be honest I bought them because I could and I didn't find a use for them for quite some time. Quote Link to comment Share on other sites More sharing options...
Chekhonte Posted November 8, 2008 Report Share Posted November 8, 2008 yeah neodymium magnets are a lot of fun. I'd been toying with the idea of getting some for years but only now have thought of an application. Quote Link to comment Share on other sites More sharing options...
cclragnarok Posted November 8, 2008 Report Share Posted November 8, 2008 You have no idea. My biggest superconducting magnet is about 12 times more powerful than that thing. And its gap is 3 feet long. Maybe you can make a coilgun out of this. Chekhonte's new magnets should make good bullets for it. Quote Link to comment Share on other sites More sharing options...
Dusty Chalk Posted November 9, 2008 Report Share Posted November 9, 2008 Somebody should make a compass out of these.I like the way you think. "What do you mean, North isn't that way? It is now!" Quote Link to comment Share on other sites More sharing options...
