Quoted from eb94114:Lloyd, I finally got around to putting some 3-in-1 oil on the shaker where you suggested. Unfortunately, I still get the high-pitched squeaking/whining sound. I get that same sound even if I just manually move the shaker around a revolution or two. Any other thoughts on what I might try? Thanks.
I used "tri flo"
A lil expensive, but never heard that whining again!
