Yep, it must be something with the little loop or swinging "U" that doesn't fall to exactly the same place every time.
But I'll clear a few things up while I'm here.
First -- the scale doesn't have some monumental "problem." Gotta realize that 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.
The scale isn't dirty, the razor edges are good to go, I've never sprayed the scale with anything and I haven't oiled it, bent anything or fouled it up. I've been using it for a good while and I've loaded about 3,450 rounds (all single stage!) since Christmas, checking my Lyman 55 with this scale.
There is no monstrous problem with the scale... I just couldn't figure out why if all the weight in the pan is hanging from that loop, it should matter in any way how the pan was placed on the scale.
I like the monofilament flishing line idea. I'd probably go nuts trying to tie a little knot and make a loop of that size...
And for the folks who are looking WAY too closely at the linked picture and not reading the TEXT very well, that's a Gunblast photo that I linked just to show you the model/brand of my scale. It's a picture for reference. That's not my scale, not my bench and I don't have it adjusted like you see in the photo. I didn't even take that photo... I found it in a quick web search just so you could see the scale that I'm talking about.
