I am in need of information on.....

scooternauman's Avatargold
I was talking to my son the other night, he was dealing with a frustrating problem, and I had another light bulb moment. Now I find myself scouring the internet trying to find information on magnets. More to the point, I’m looking for information on how NON electric magnetic tables work with an on/off switch. I’ve spent the last 15 years of my life as a machinist but never had an opportunity to take one apart to see how it worked. Now i’ve been laid off and dont know when I’ll get the opportunity to do that. Does anyone out there have that knowledge or know where i could obtain that information? Preferably with pictures, lol.

I just started looking around for you too… Do you mean nanotechnology? This article might lead you somewhere in the right direction anyway…

No, nothing that complicated, gees. lol. Thanks though Jane, I’m trying to find out the secret behind these http://www.harborfreight.com/12-inch-x-6-inch-m...

Hey Jim, as Forest Gump says" I’m not a very smart man" When it comes to mag’s and stuff. What do you mean by flux lines? The way I’m thinking is theres something moving inside the chuck, I’m trying to figure out if its actually that simple, moving a magnet closer and further away from the top surface. BTW, I love machining , I would love to be able to buy a couple of nice CNC’s to put in my garage, to make what i want, when i want. And you are so right about being dependant on the economy, i myself just got laid off in Sept. and this economy isnt looking too hot right now, or for the forseeable future. Thinkin’ bout goin back to bartending, that was always fun,lol.

Thanks Jim, that does help in understanding the principles of how it works, I guess I really need to find a diagram of the internals of a mag. table to see if I could really apply it to this idea, I’d like to try to make my own somehow for this experiment. And good luck with the whole…“figure out what magnetic and electric lines-of-force are, then they will probably be very close to finding the elusive unified-field theory/equation/particle that ties electric, magnetic, gravitational, and the strong and weak nuclear forces together.” LOL, right over my head… Thanks though Jim.

2 cents Scooter…Kelly has pointed out on more than one occasion before your time here that innovation with magnets or copper as features…are basically starting off “behind the 8-ball” in EN searches. Cost prohibitive, I believe, but just FYI

Thanks biskit, I did read that on one of the blogs but I still gotta try it. This is for a modification of an existing productline that already sells for several hundred dollars, I believe the precieved value that this type of mod. can do for the product would be well worth it. Without giving it away, just think snowboarding and skiing and how much they’re willing to pay for the next hot item. I probably gave it away didnt I?

Please enlighten me jim, what are the 2nd and 3rd laws of thermodynamics?

thanks Jim very interesting, although i’m not sure what it has to do with this thread.

Lol, You did get a little off track there, but you came through with flying colors in the end. Thanks for all the info, I appreciate it.

Jim ,dont vacumm chuck’s hold non-ferrous materials without clamping ?

Non electric magnets can’t be turned on or off. The can only be moved away from magnetic material,even blocking he field won’t help as a magnetic field moves through almost anything . It is unlikely that you could generate enough magnetic force to do much without using electromagnets.

With regular old magnets it is all about mass, and well you don’t want to carry around a 200 lb magnet generally speaking. Even so that magnet would get quickly weaker as it is used to attract or repel other magnetic objects.

If you ever had a set of magnets that you got as a kid from a science kit, and if you stored 2 magnets repelling each other, they are basically not magnetic anymore inside of a year. That is why electromagnets are used for just about everything. They do not weaken and the poles can be reversed or made stronger with increased power.
Most electromagnets have regular ferrous magnets incorporated in them, but in most cases the electromagnet is being switched back and forth which preserves the ferrous magnet. ( as in speakers and motors).
That is about all I know about the magnetic field :)
I was obsessed with magnets as a kid and I wanted to invent a magnetic skateboard like the one used in the movie " back to the future2". Actually they never said how that was supposed to work, but I thought I could manage it with magnets. I’m glad I never got out of the brainstorming stage on that one.

Hi John,
For images, I’d recommend looking at the USPTO website, since patent images should contain enough detail to illustrate the operation. For example, search patent applications, and put in this number: 20060012094, then go to the images so you can see this one with a rotary mechanism.

Hey ken, i put in that # and it says no patent under that #. Thanks though.

Hey, that was a good suggestion by Ken…Looking at the different patent drawings!

Hi John,
For specific details for the products you have used, you could search patents for the manufacturer’s name as the assignee (using the dropdown on the quick search page) on the USPTO site.
When researching an idea, I’ll often look at related products in stores and jot down the patent numbers from the package, then look up the patents to see what features the claims actually cover. From there, the “references” and “referenced by” lists are useful to find older and newer concepts.

Thats a good idea Ken, thanks. Never thought to copy those patent #’s for use like that. Very smart.

Hi ken, I just want to know when you become a LPSG8. Because, I Don’t. Know who won this year.

Hi Eduardo,
For me it was the BB&B Paws Life search – I was one of the five G8s from that search.
