I have an old RCBS beam scale, I guess it's the 510...it goes to 500 grains on the beam and the tenths area goes up to 10 grains. It has been sitting in its box in the top of a closet for years, and when I got it out I could not get it to zero in. I polished the discoloration off of the magnetic damper on the beam, cleaned off the knife edge things that set in the balance groove, and cleaned the groove out with a Q tip. It was still 3 grains off...would bottom out like the magnetic damper end was too heavy. I tried adjusting the leg all the way up, and even got out a level and leveled the scale itself. And yes, I did have the powder charge pan in it.
My question is have any of you fixed one that had this problem?
I took a paper clip and snipped off some small pieces at a time and put them in the powder pan until I could get it to zero out. I then took the screw out of the thingy do hickey below the powder pan, where the shot type counterweigh stuff is, and dumped them in there and put the top back on.
I then weighed three different 158 grain coated bullets and all three came out to 159.3 grains. I then weighed two bullets, that should weight 318.6 grains, and they came out weighing 318.5 grains. I then weighed all three bullets, wich should have came out to 477.9 grains, and they came out to 477.5 grains. I then took the bullets out and moved all the adjustments back to zero, and the scale popped right back to zero.
Also, does anyone have any suggestions for something I might have around the house that I could use as a check weight?
I think I'm going to order a new digital scale just to compare the weights between the two scales, and see if I like the digital one any better than the beam.
