Please explain my scale frustration!

The guys are right about friction at the loop. It is supposed to be another fulcrum and on an old fashioned analytical balance it would have a secondary knife edge of its own. You are just seeing the limitations of the loop and hook as a substitute for that. If it were working perfectly, when you shifted the pan everything would tilt just enough to recenter the pan mass under that point on the beam and there would be no change in weight.

Clean it, as suggested. You might try lubricating it the way a watch movement is, with whale oil. However, as that's scarce these days, you can remember that automatic transmissions were first developed using whale oil and that modern ATF was developed as a substitute, also due to scarcity of whale oil. I would just dilute the ATF with about ten parts odorless mineral spirits as a means of apply a very thin coating. If the cleaning doesn't do enough, that may well settle the problem. Just be aware there is dust in the air, so you may need to clean it periodically. I always cover my beam balance with a plastic bag hat when it isn't in use.
 
This scale measured .3 different from the two positions in the photos.

First step is to figure out why is measuring different, then you can cure it.
 
Sevens, I did a little loading today and checked out this phenomenon you are experiencing with my scale (RCBS/Ohaus 10-10; made in China unit).

My charge weight was 23.3 grains (AA2230 in case it matters). I sat the power pan down onto the platform in a canted manner - about 45 degrees - and it mattered not. The scale balanced the same as if the pan was sitting on the platform square.

Just thought I'd give you that data to chew on. BTW, from what I know (I'm not an expert on physics), it shouldn't matter. I have no idea why or how your scale is doing what it's doing.
 
I bought the Dillon Eliminator a little over a year ago, so a much newer version of the OP's scale, and have never had those problems with it. In fact, after reading this thread, the other night I tried to make it do the things the OP posted, and couldn't get it to malfunction that way. I'm assuming they must have fixed whatever the problem was 7 years ago.

Oh, and I really like this scale. I use it more than my digital and certainly I trust it far more.
 
It's funny that pan hanger will have a knife edge on one axis and not on the other. This is still the source of the problem. Get them loops to slip!

Sevens,

As they say in science fiction, "Time Swerved!" If I understand it correctly, that means you can visit yourself in prison, so long as it is done at two different ages.

As it seems grammar is very much come & go in discussion forums, I hereby request a sentence fragment.

I wanted to write a more appropriate reply, but.
 
if I place the brass looking pan in the same exact spot, I get the scale to zero perfectly each and every time. I can take the pan off, run around the man cave, put the pan back on and if it's in the same spot, it will zero.

So, what's the problem?? Other than something isn't meeting your expectations?

if you do things the same, you get the same results, right? No problem.

When you do things differently , you get slightly different results. IS that a problem? If its consistent, I'd say its not a problem, just different.
 
^this was also my conclusion. It was a frustration, an annoyance, but it was more than half a decade ago and I have rolled some 60-70k rounds since I opened this discussion. :cool:
 
My point for dead-thread resurrection

My only point was to alert those with unsolved scale inconsistencies that what I found in the hanger assembly completely fixed my issues. Aluminum shavings don't belong in there mixed up with the bearing weights, and since I removed them I have no unrepeatable scale zero inconsistencies. Now I push each scale weight and the hanger loop back into the same position before I weigh anything, and I hold zero perfectly. H110 meters very well through a HCBS Precision power meter, and I no longer am fooled into making adjustments when I periodically check weight with the Dillon scale. Maybe it will help someone if the look into their hanger assembly...
Good luck
