Thread: Mechanical scale wont zero

SO I bought a scale as a replacment for my crappy lee set (dillon precision but ohaus built).

It wont zero, the scale just always rests on the bottom of the support. Everything is straight and I have tried on a level surface.

Has anyone had this issue? there are ball bearings under the powder pan that I assume are used to calibrate the scale from factory, am I going to screw things up by adding some extra ballast(thinking shotgun shot) until it will zero?

Cheers
Nick

Can you load a picture of it in situ?

My rcbs scale has a foot on the left hand side that winds in and out to zero the scale. Yours might have something simimar. Or you could pack one side up with paper or something to make it balance.

Ohaus make the rcbs scales that i have also. And as flincher says you can wind the leg up or down to zero.
Is it new or second hand?

Yeah the levelling foot, it still wont zero even wound right out or in. The arm just rests.

To get it to level, I have to lean it on a downward 45 deg angle. Im wondering if the previous owner had it apart and lost some ballast

Are these two reversed?

looks to me like you have a shortage of weight in the powder pan base.

You're going to have to add some small lead balls to adjust it to zero.

I've some spares if you're stuck. The markers are in the correct position/order.

Looks brand new who did u buy it off I'd send it back and ask for a new 1

My son pulled mine apart and lost some on the ballast out of it and so had the same problem, just put some more ballast/weight in it and you will find it will be back to normal.

if adjusting the feet didn't work check the knife edges foerr rust or a powder grain tap the beam when its like that does it move freely and swing back without catching .What weight is needed to get it to zero, and is it repeatable. Lastly is the pan correct for the balance

Good point about the pan. It doesn't look like it's sitting as well as it should. Maybe a different weight?

Doesnt matter where u have the weight cause it's all still hanging from the same point and is correct pan just on backwards might be hard to get exact weight right but give it a crack

I tried moving the pan, will just buy some cheap shotty loads and use some shot to even out the ballast. Its not brand new but it is in good knik. The pan looks to be the same as the OG ones I have seen.

Good point. But once zeroed he could confirm its accuracy with another scale just to be on the safe side
