Lions, tigers, and large neodymium magnets, oh my!

My screw drivers pick up all kinds of metal shop steel dust is why, one of the problems of having a small time machine shop in your garage, the stuff gets everywhere....I have to demagnetize my digital calipers especially, real tiny metal dust gets in the jaws thats hard to see but can be measured, especially when you don't want to ;-)

The demagnetizer doesn't screw up your digital calipers? I was under the impression that messing up a magnetic strip on those would cause them to no longer function.

I don't want any tools of mine to be magnetic unless it is a fundamental duty to that tool. It is just too much of a pain. I've almost ruined my really nice dial calipers by picking up too many steel shards. *sniff*

OK that makes sense.

I keep all my electronics tools separate. I like magnetic screw drivers because they can remove screws from recesses, and hold them in place when screwing them in. Some of my small screw drivers came with magnetized tips.

What would be the minimum size for a pair of magnets to charge pickups? Is 3 x 1/2 x 1/2 too big?

For pole magnets, you don't need anything so long because you can pass the magnets through the field to magnetize them. If your goal was to pass through a bar magnet vertically rather than horizontally (which might make sense for a few reasons) then you'd need something long, but you can remagnetize alnico with surprisingly little. I have 1/2" cubes that will reorient rods very easily.

I took a chance and ran the digital caliper jaws over the demagnetizer, the calipers are from Harbor Freight and it didn't phase them at all, so I wouldn't worry about it unless you have a very expensive one you don't want to risk. I did this with the them turned off, also.

Maybe just doing the jaws is what makes the difference.

I prefer dials anyway, so I suppose it isn't all that important.

Like some of these I guess is what you meant !

I wouldn t risk myself with these ...lol

Digital calipers work with a capacitive sensor that shouldn't be affected by magnets in the slightest. I'd be more worried about the delicate gears inside a dial caliper.

Ok cool to know that

You re from Scotland , do you happen to know ACG s Allen & John East too , ! just curious

I'm from NJ, but I know Alan! He makes some great basses.

I didn't think they worked with magnets.

Yep true , & nice , good preamps too .
