RCBS 505 scale jewels cleaning needed
Quickie question tonight.
Been doing a little reloading tonight to kill the evening. I have a RCBS 505 beam scale. Have had it quite a few years. And I've never cleaned its balance supports points. I just took notice the scales balance beam is getting sticky upon measuring level. Question: Just what can I use to clean those balance beam supports points with? Is there a need to take those supports both apart to clean? thanks for the help guys.. S/S |

No need, just take the beam off and clean knives with alcohol, likewise the seats, I use a Qtip, and alcohol.

Hey thanks for the advice hooligan1. I just wanted to make sure whatever I used didn't damage it. I got some rubbing alcohol here that should work than. "Yup!! I'm back in business Sir"_

Also…check the magnetic damping. The eddy current plate on the beam that moves between the magnet poles is usually fine, but sometimes tiny bits of iron filings or shavings or rust dust can accumulate in the magnet and start to drag on the plate.

Yeah. Pregaussian balance technology. Nobody thinks of everything.
I'm sure the plates are not steel. You wouldn't want the magnet trying to grab it. Probably just a hard copper alloy. Either copper or aluminum work fine to short out eddy currents and load the generator you create when cutting a magnetic field with a conductor.

Plates: I didn't scratch the copper to find out. Nor take a good look at the Hornady one. That ones in my travel bag. S/S |

The old Redding #1 and #2, for sure, were viscous fluid (oil) damped scales (I don't know how many models beyond that). Member Armedandsafe says he bought his in 1948. They do show up on eBay every now and then.

These were a jewel in the ruff , but I brought em back !!!
The knives had apparently been abused to the point the edges were turned . I slowly resharpened em & now these scales will weight dust !!! Webster W-2 scales 350gr capacity. Don`t recommend sharpening knives , but I had to try !
