Rcbs 5-0-5 scale won't stay zeroed

Best thing you can do is replace it. When you get a decent scale, you will wonder why you held on to that 505 for as long as you did.

Gotta go with you on this one, Gene. My 505 is nowhere near as old as Mopardoctor's, holds a good zero, and I still don't know why is taking up space on the bench. RCBS could not have put less effort into the manufacture of this unit. It is only by virtue of gravity being the same at both ends of the arm that it measures reasonably accurately. (The scale came with the Rock Chucker supreme kit that was my starter press.)

I'm with Nuggin and '55. My 505 (40+ I bought it in the 70's) is simply in a box, waiting for the time if the grid fails and I don't have a generator... the chargemaster combo with the straw trick is my go-to. Calibrates great and cross-checks with check weights.
Not afraid of stick powders any more!!!

Love my Chargemaster, but there is a 1010 on a leveling plate nearby. My bench will always have a balance beam scale.

I doctored my old rcbs beam scale up to measure one kernal of powder. Glued a needle to the end of the beam to overlap the balanced line on the frame. Stoned the balance points on the beam to razor sharp edges, polished up all the contacts for the pan and holder. It works pretty good now and didn't cost me $60-80 that the guy charges to do this to old scales. Can't remember his name but I think he is out of the game of modding scales. I also cut out notches in the small brackets that hold the plastic balance points on the frame. This lets you see where the beams balance points are sitting and not rubbing against the metal bracket on the inside.

Scott Parker, I believe is his name, and I understand he is very busy.

[joedirt199]

Yup that is right. Some guys had issues with getting their scales back in a timely manner. Guess that is when he got busy.

I liked mi 505 scale.. and I like more my 510. I would not trust an electronic scale for the same or lower budget. Electronics can be very heat sensitive, and if this happens while you are using it, no way to spot it.

Redding has a mechanical scale that is very good and unlike the junk RCBS is pushing now, it's made in the USA.
