Lyman D7 scale

any one used this scale ?.wondering how good it is and if its magnetic balance

I used one for years before I went digital. Did well.
It is magnetically damped, if that is what you mean.

I got the scale, setup was simple, whats the knob on the right for ? has an arrow and the word UP on it ?
I didnt get any instructions with tthe scale.

It is a beam lift. Turn the knob to "UP" and a bar lifts the beam off the knife edges (pivots.) It is to keep the knife edges from wearing with every little draft in the air while the scale is not in use.

Thanks, just found it, ( the post) it was up inside the bottom, works great.

How does one measure SMALL powder weights on this thing? The manual is pretty worthless - i.e. .45ACP - 5.1 grains of Winchester 231... the smallest indication on the beam is for 10 grains! sub-scale only goes up to "5" - Do you slide the compensation poise up toward the 5 to achieve this, and what are the corresponding indications?

If 10 is the lowest number on the left side of the poise, then 10 grains is the lowest amount it will measure.

Sure there isn't a zero?

A D-7 will weigh down to .1 gr., or zero actually, same as any other reloading scale.

Only way I'd have a digital gimmick is if someone gave it to me. I used to maintain those quirky things in the space program, no way I would pay for one now.

+1 on what wncchester said,I've had and use a set of Lyman D-7 scales for 20+ years.

For the D-7

On the right side it will measure up to 5 full grs. in 1/10th increments with each move of the small counterbalance. On the left side it measures in 5 gr. increments with each move of the larger counterbalance.

After zeroing the scale,If you want to weight out 6 grs. set the left adjustment on the first notch which is 5 grs. and the right notch on 1 which is one gr. for a total of 6 grs.

If you want to weigh a charge of say 10.2 grs. set the left adjustment on the second notch which is 10 grs. and the right adjustment on the second notch form the zero position which is 2/10 tenths.

Anything under 5.0 grs. just put the left setting on zero and use the right side. Anything over 5.0 grs. and you have to use both.

Yeah, dummo here finally noticed that 10 divided by 20 = 5 on the scale. Checked it against my ancient LEE and it's spot on; figuring out the zero is very intuitive, too. Thanks to all who laughed at my apparent inability to figure out the obvious.

How would I read a charge of say 22.5 GRS.? On that scale can someone illustrate that for me.? Thanks
