Soon after wearing out the first set of strings on my rubbish DIY kit soprano (the one shown in my avatar), I noticed an annoying grinding/ semi-binding in the open backed C string tuning gears. I first thought I'd gotten something between the gears such a fragment of toothpick. When a close inspection revealed no foreign matter, I considered, then rejected, WD-40 because of the anticipated volume of over-spray. By chance, I found my son's old model train oil, a tiny bottle with a cap that resembles a tiny tube of caulking. He'd capped the tiny opening with the type of pin you'd put on a map at least 15 years ago (he turned 29 last week).
Long story short, I laid the uke upside down on my folding table and carefully dropped tiny bits of the train oil around and between the tuner gears. Still upside down on the table, I then ran the tuners down and back up several times, then left the uke in that position overnight. No more grinding! The lube job worked perfectly and has thus far lasted over 3 months. In the future, is there a better choice such petroleum jelly or the sort of graphite powder we used on the axles of Pinewood Derby cars in Boy Scouting?
