Hello,
I have a model 3100 24" Beaver scroll saw from the 40's. In the manual, it states that the oil should be checked and changed periodically in the lower drive case. The actual drive arm of the scoll saw operates in oil bath format. Basically, the lower unit rests in a pool of oil. I was doing a tune up on the saw and I determined that the oil level is a little lower than where it should be (oil level is ok but needs to be topped up). My problem and reason for this post is that the manual from the 40's states to periodically change the oil but does not say what type of oil to use. The oil that's in the bottom unit seems clean and all I want to do is add to it, but I'm not sure what type of oil I should put in.
Can anyone point me in the right direction regarding this? I need something that has good lubricating qualities but with a fairly light viscosity so that it can lubricate well at room temperature. Definitely not a gear oil, I don't think, as it would be too thick. I'm leaning towards something like a 5W20 or 5W30 but a friend of mine has told me to stay away from the "W" oils as they contain detergents which aren't' necessary and they are more geared towards motor oil. How about an SAE 20 or SAE 30? Would they be appropriate? That is what my friend suggested.
And one more thing, the oil that is in there is the typical light golden colour.
Sorry for the long post on a basic topic. Thanks in advance for all your help!
