Re: Lathe Maintenance/Tick Tock Productions' videos
I haven't seen the video, so can't comment on that.
Most of what I know about lathe maintenance(which isn't much!) I've learned second and third hand.
Basically, what I've been told is that the most important thing is to keep it clean and well lubricated.
If your lathe hasn't been used in a number of years, you'll want to break the headstock down and clean it well. This part is relatively straight forward, although it may not be immediately obvious. All the ones I've seen come apart more or less in the same way. The first step is to remove the drawbar, which is a tight friction fit inside the spindle. Remove the two split rings that act as dust guards around the oil ports-these just pull off, although some twisting might help them. Unscrew the knurled ring that allows you to adjust the play in the bearings. Then, loosen the set screw in the pulley. The rear bearing-which is a tight friction fit onto the spindle-can often then be pulled off, although occasionally a few LIGHT taps on the spindle with a watchmaker's brass hammer may help get things going. Once the rear bearing is out, the spindle can be pulled out through the front bearing-just be sure you support the pulley to make sure it doesn't crash and break.
Once you've cleaned all the bearing surfaces, you can put it back together. Just be sure the set screw of the pulley is aligned with the flat on the spindle, and make sure you get the rear bearing keyed onto the spindle correctly. I was taught to set the bearings as tight as possible that allows the spindle to still turn with no apparent resistance.
For oil, I use 3-in-1 oil, although you will likely find a lot of debate about this. Others I know use various grades of automotive oil. I think more important is that it be oiled regularly and correctly. I was taught that oil should be added until it runs out, and the excess wiped off.
As for the motor-be sure the cord is in good shape. Most of the lathe motors I've seen have felt wicks in the bearings that need a few drops of oil occasionally.
