electronic scale ??

[Erik Cortina]

your first definition is of MAGNETIC materials..so not what we are looking at.

i do not see the connection to eddy currents in the magnetic dampening of the scale....

i am still listening.....

1 Problem
If one pitches a penny into a large magnet, eddy currents are induced in the penny, and their interaction with the magnetic field results in a repulsive force, according to Lenz’ law.

Magnetic Damping

In the present problem the magnetic field is spatially uniform, so the magnetic flux through a moving loop does not change, and no eddy currents develop. Yet, there exists a very weak magnetic-damping effect, as discussed below.
The cube has mass m = ρa3, where ρ is the mass density of copper, so in the absence of the magnetic field it oscillates vertically with angular frequency

In other words "Bazinga" : Are YOU listening NOW...........



Sorry bozo699 the Devil made me do it. :

Jimmy Cagney also explained eddy currents in the movie "White Heat"
"Come and get me, Copper " ;D

Duh! ;D

Thank you gentlemen for all the replies and discussion. Having read every reply, I think I fixed it
I came to believe that the only point of friction could be at the knife edge of the beam axle.
It also made sense to me that magnetic dampening could serve to further the root problem.
I cleaned the beam again and the seat it rests in, this time with something more than just a rag, I used some brake cleaner. I then stoned the knife edge and polished.

Problem solved. I've just loaded 50 rounds without a hitch. I drop Varget to 24.5 then trickle up to 25.0. It read every add as smooth as it ever did. I checked my zero every 10 rounds...dead on.

I apologize for my ignorance in not realizing that just because you can't see the dirt, doesn't mean it isn't there. I haven't been keeping my scale covered, lesson learned there too. Thanks guys, your awesome!

That's the way I did it for years before I got my Chargemaster; drop short and trickle up. A total pain in the posterior but it worked.
