... that I spent several hours in the garage over a hot lathe making stuff. It's just as well because it was freezing cold out there.
All the "custom parts" for pedal-car 2WD units are done.
The lathe has started "shrieking" again
and I measured the temperature at all the drivetrain bearings and they were all about the same (39°C). I cannot actually hear which one/set is complaining, I tried listening with a long screwdriver pressed to each but the noise is everywhere drowned by the belt-noise and none stand out. I put more oil in every button oiler and dashpot (not empty anyway) but it still shrieks.
Maybe the machine oil just isn't getting past some corrosion or build-up (the machine did stand idle for 40 years) and some penetrating oil is required.
