RCBS 304 Scale

[Suasponte]

Does anyone out there have one of these??

I picked one up in a lot of boxes I bought at a estate sale.

My question is?

I am having a bitch of a time getting it to zero. The room has zero air flow and the scale is level. Both weight adjustments are zero and the dial is zero. I have adjusted the balance compesator to get it zero'd.

However, it does not hold the zero. Also, when I move the poise to 20 grain and put a 20grain check weght in the pan it falls about 1/8" below the zero line. This same check weight hits 20gr on my Denver Instrument MXX-123 so I am confident of the value.

Any suggestions?? I have cleaned the scale as much as I can. The balnce bearing are enclosed and I do not want to rip it apart.

HELP!!!!

Also, let me add! The previous owner glues a needle point to the end of the pointer. There are some needles taped to the bottom of the scale support as a counter weight I assume for the needle. I know this problay has a affect on the scale. But I have seen guys do this to other scales with no affect that I could see.

Sounds like the bearing area. Are the pivot points on the beam undamaged?

call or email rcbs. They will give you instructions on how to send it to OHAUS with an RA number. They will replace it or rebuild it and tune it up and ship it back free of charge

I cannot tell without disassembling the scale. The pivot and bearing area are enclosed.

I intend on calling RCBS Customer service Monday. However, these scales have not been made for several years to my knowledge.

I have heard that this is one of the better balance type scale and would like to keep it in the mix. However, with the way it is now it may get sold. Do not want to spend a bunch of $$$ on a scale.

I have one of those scales and prefer it over the electronics. It is my hope it never fails me. I had a friend send one in and the parts were no longer available for repair.
Good Luck!
