I wish I could claim credit for that one, but the suggestion came to me years ago from another ham who's identity is long forgotten. Perhaps from this very list. >I'd like to carefully remove the old lubricant and sparingly lube >the VFO where necessary. What' s the best way to go about doing this? The last time I did the ball bearings, I cleaned as much of the old grease out as I could with a paper towel moistened with alcohol. Then I troweled fresh grease in between the bearings as I turned the shaft. I think I used Phil Woods bicycle grease on that one, but it could have been TriFlow (also a bicycle grease) as well. The results were good. The contact between the brass main shaft and the outer shaft tube seems to benefit from lube as well, but this requires more disassembly. I think I used TriFlow there. Don't loosed the nut that holds the front dial on, you will have hours of fun getting the dials lined back up right. 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
