Great Magnets

A big if here but if you have a microwave oven headed for the dump then you can destroy...uhdismantle it and get the magnet off of the magnetron. I think that's what it's called. I have 4 of them and all are about 3/8 thick by about 3 in diameter with about a 1 inch hole in the center. I scrounged them off the street and if you need a good magnet there is a source for free...except effort. 

Never do anything you don't want to explain to the EMT.

Re: Great Magnets

Another source for magnets are old hard drives.  There are 2 rare earth magnets in there for the voice coil head positioner.  Usually 1/8 to 3/16 thick curved and very strong.  I use one to keep my drill press key attached to the machine, my buddy is left handed so he can swap sides if he is using my shop.  I use 1 to hold a clip board on my cabinet and 1 to hold a note pad for the next HW store run. My wife has several she uses on the refrigerator to hold a calendar, shopping lists and coupons

Re: Great Magnets

For anyone that is a fisherman that has had a trolling motor go bad, and to costly to repair. Inside surrounding the lower motor casing glued to the inside is one of the most power full magnets that I have found. May take a chisel to get them loose....

If you can find an old stereo speaker where the cones is torn or trashed, harvest the driver magnet. The bigger the speaker, the stronger the magnet.

Re: Great Magnets

Old guitar pickups are great, too.  The alnico magnets stick to the 'fridge like gangbusters!

Re: Great Magnets

Panel meters from old electronic equipment contain magnets that encompasses a wire coil on the meter's needle movement. The size and power of the magnet will of course depend on the physical size of the meter. Bob

Re: Great Magnets

For small, but very strong magnets, check out the brush heads of a Sonicare tooth brush. They are good for catches in boxes, etc. approx 3/16 x 1/8 x 1/4

Re: Great Magnets

check out old old old hard drives. They usually have 2-3 rare earth magnets inside. DON'T get your fingers caught between them unless you like blood blister blue as a color.

Re: Great Magnets

Ditto here on hard drive magnets. I do computer repairs, so have a pretty constant supply. I use one to hold up a hammer , 2 together to hold a 25' tape. (2 only because of the tape being bulky, it is safer) I have them epoxied to my lathe to hold the wrenches, and other tools, I use them attached to old axe or shortened shovel handles for that elusive screw or socket that rolls under the counter. I even have 2 holding my electronic cross cut miter gauge to the wall. It needs 3 if you put a long auxillray fence on it. Grant Dorcas
