I have a beam scale that I have not used for a long time, and want to start using it, however I do not remember what kind of oil that is supposed to be used. The scale is oil damping. Does any one know what kind of iol is used in these scales. Thank you for your help
 
I have a Redding beam scale i inherited from my Uncle... 5W-30 works well for me
 
Its been awhile since anyone made beam scales thet were oil dampened. Contacting a company (if its someone that is still in business) might be like contacting a car company and asking what weight oil you need to use in a zenith stromberg carburetor (likely not going to get an answer or even a guess, everyone that knew retired years ago)..

What is the make and model of the scale you have?

I have a Texan, bought in while i was in FT. hood in 69.
 
any normal weight motor oil will work. atf, or sewing machine oil would be too light, imo. i have an old redding oil dampend scale, by the way.

luck,

First of all, there is no need to use oil, because all it does is slow the beam so you get a faster reading. The thicker the oil, the faster it arrests oscillation. Thin gun oil works fine.
 
I have a pic of the Redding instructions, but can’t figure out how to post it.

It says to fill the reservoir to 1/4 inch of the top with #30 motor oil or equivalent.
 
I forget the brand of scale my grandfather had just now but I remember that he used 3 in 1 oil in his. I would think that any medium weight oil would work OK in it. Back then most of the population put their own oil in their car or lawn mower so a commonly used and already on hand oil would be what they would set it up for IMHO.The thicker the oil the faster it dampens the movement FWIW.
 
I believe that 3 in 1 oil is 30 weight. Transmission oil is 10 weight. I would use what I had on hand but if I had to go out and buy it specifically for this scale I would look for a straight 30 weight oil.
 
Forget the oil.

1. Clean heck out of both bearing/surface contact point. Dry off w/ final Q-Tip.
2. (and this is the important part) As the scale is coming to rest, gently/repeatedly tap your finger on the table next to it to slightly vibrate things into final position

Very fast, and works all the time, everytime -- fully repeatable readings.





FWIW, I have three digitals and three beams -- the oldest beam being my simplest/most reliable 60-year old Texan used as discussed above. The RCBS 1500 and the Texan are my Go-To scales

I have two, oil dampened scales. I use the lightest viscosity oil I have on hand, last time it was compressor oil. Mineral oil was recommended when these scales were popular and anything much heavier will slow the swing/centering way down...
