Had a discussion with Cody about putting magnets on the outside of the trans pan to catch particles on the inside.
I suggested neodymium magnets, since they are so strong that you can use a small one that won't get snagged, and still have more than enough power to collect particles through the steel of the pan...
Anyway, Googled up and found two sites that do nothing but sell neodymium magnets.

There'* some neat stuff on here, lot'* of possibilities for small projects. I ordered some discs with counter-sunk screw-holes. Gonna use them to keep the cats out of the cabinets...they're 3/4"x1/8" and they can lift over 33lbs...

Need some place to hang a work light, and don't have a handy projection?

They also sell some real monsters, this site has a 6"X1" disc that has a pull force of 540 pounds!

Anyway, on the original topic, these are the ones they recommend for oil pans. They're high temp material, so they can go to 300* without losing strength. Regular Nd magnets can only go to 175* before they begin to lose strength.

If you've got some old hard drives laying around you can always hack 'em open and take the magenets out of them. I'm not sure what they're made out of, but they're pretty strong.

500+ pounds of pull from a 6" big magnet? holy ****!

anyone got an old used monitor?

that'* what i was thinking..

jesus, i want that big one, i can imagine there would be alot of injuries from that tho, lol. that would probably mess with the internals of the trans huh?

This is what I did last year.

(long thread but worth the read – plus some cool home videos in there)

Definitely the best magnets to use! I did not get high temp ones because though they may operate better in higher temps their strength isn't nearly as good. I haven't had any problems with the NdFeB magnets I've used (strength grade N42 IIRC). Plus they only BEGIN to lose strength at 175*, and these magnets will not get that hot or much hotter on the outside of the pan.

Objects can become airborne if you have a big enough magnet. Fun stuff but potentially extremely dangerous (deathly).

Yeah the high-temp ones aren't totally necessary for a trans pan, ours trans shouldn't get hot enough to kill a regular one.

BTW, that 540lb magnet would have to be handled with EXTREME care. Not only could it could SERIOUS injuries, but if it was allowed to slap onto a piece of steel without control, it would probably shatter...

IIRC Haro broke a few...

Mine made it on the bonne without a scratch, but damn they were strong...

Wish I had taken them off..

I broke a few too playing around with them in my videos, and these were the small (but still strong!) ones. I had blood blisters and red marks on my hands for weeks. Those very large ones WILL shatter if not handled with care. They'll also shatter bones.
