I just picked one of these up at a garage scale mainly for its coolness factor, since I weigh on a RCBS 5-0-5. It's very nice, but ya'll probably know that. Question: how do you weigh to 0.1 of a grain? It looks like it only weighs to the 1.0,2.0,3.0,etc. Anybody have any experience with this scale? Thanks

does it have a micrometer poise (cylinder) out on the right end?
from pictures I just looked at (Google images) it looks like its the same as an Ohaus 10-10

here is a link to a manual for the 10-10 - it will explain the micrometer poise

if its not the same maybe Super Bluejax (Uncle Bob) will come through and find one

that's a good lick, thanks

but I don't have that micrometer poise thing on the end looks like

If your beam looks like this, each graduation to the right of the fulcrum is 1/10th of a grain. Each graduation to the left represents 5 grains.

Can you post a pic?

Chad has it right, this is one of the finest scales ever made, accurate to less than 1/10th of a grain. Just be sure to zero out by leveling, I have used them for 40 plus years, currently have two of them, just because I find a deal on eBay occasionally.

Does this help you?

I'll post a picture when I get back home. Thanks for the great info so far.

I'm having problems zeroing and the knives flop about a bit in the saddles

I cant screw the thing low enough to hit zero

There's a screw on the pan hanger that allows you to open it to add or remove weight (lead shot). Carefully remove the screw, open it up and add a few pieces of shot. This won't alter the accuracy of your scale at all and is described in the older owners manuals.

I believe your auxiliary 500 gr weight actually weighs 25 grains (may be stamped on the weight), so you can use it to check your scale when you're done.

Thats good info, now I need to figure out why it rides funny in the fulcrum points. I cleaned those little saddles I have to check to see if I got them back in right.

I was able to add a sliver off a lead sinker (I don't have lead shot) to the pan and was able to zero. Now I weighed the aux wt. and also used a very 158 grain bullet and my trusted 505 scale, I think this Ohaus is off 0.1 gr. How is that mitigated? thanks

I like your magnifying glass addition. You remind me of my grandfather. He had an ingenious solution for most everything.

I'd like to take credit for it, but it's not my scale or my idea.

Good advice from everyone. I've used an RCBS 5-10 by Ohaus for 35 years. It's my only scale and has never failed me. No batteries, no electronics, no BS. So you have to pay closer attention to your poise settings...... What's the hurry? Relax and enjoy your hobby!

Another hint; watch where the poise sits. On my great Lyman/Ohaus scale if I remove the pan quickly, the beam will sometimes bounce and the 1/10th poise will jump into another slot. A while back, I wasn't watching and loaded several .44 magnums .4 gr. heavy and I had to dump all 40 previously charged cases and start again ( I weigh all my .44 magnum charges...).

That magnafying glass is a great idea, and so is the set-up it's sitting on. But that's still not enough to make me want to ever use a balance beam again. I quit using them when I retired and didn't have to load at work anymore.

My more recent 10-10 has a little plastic set screw to prevent poise drift. Ohaus makes great scales.
