Thread: MY ohaus RCBS beam scale needs attention

I have an original RCBS OHAUS beam scale . I have looked after it really well , and even have original test weights to calibrate it, and its box . But . somehow i have lost for 1/10 grain measurements sticker label that was on the beam. If someone could mic up the label on theirs and maybe send me a pic i might be able to make another label and stick it on .
If i caan restore it , i,ll offer it for sale and buy an electronic scale .
please take a look at the pic .
cheers

I gave a 10:10 and the fractions are etched into the aluminum either side of the zero mark. I'd be surprised if they would use a sticker maybe that model never had them. I can measure them but there's no guarantee they will be correct.
The best option would be to use the vernier and weigh increments zero the vernier and mark the pointers position.

Measure the thread pitch, It looks as though there is one complete turn of the cylinder per grain, My Ohaus 5.0.5 which is clearly much older has separate counter weights for grains and tenths. A more bullet proof solution.
GPM.

this is what i,m looking for ...

I misread your initial post, my model has graduations either side of the zero mark and I thought you meant those. Grandpa is correct it's 1 rev per grain and that should be easy to mark out once you find your zero point.

count the threads in your photo bud...then one turn per revolution...job done...

From the very left of the label to the zero is 0.531" or 13.5mm, from the very left of the label to the 10 is 0.118" or 3mm. Each increment is 0.0413" or 1.05mm

perfect , just what I was after . I owe you a favour .
