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..

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.

That info I had to pause a couple seconds to digest.__ But I do know just where on the beam your describing that part. On my 505 its a copper plated steel blade and on my Pacific its a small blade of steel both mounted almost next to their pointers. Looks like I only did 1/2 the cleaning job tonight Unclenick._:o I wonder why hooligan1 never mentioned that?_:mad:
 
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.
 
Because we old coggers used oil dampening scales before magnetisum was invented

Well I've been at this hobby since Nixon quit. I don't believe I've ever seen a oil dampening scale now since you've mentioned it? I guess I must still be a newbe yet compared to you guys.

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.

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 !

My first scale was oil dampened. It was a Herter's I believe. It, along with all my original loading stuff burned in a fire. Oil dampening scales were a pain...the oil was in an open-top reservoir with a little paddle in it. The oil would work its way out (capillary action?) of the reservoir and have to be topped up from time to time.
