G'day everyone,

I it was a very busy 2021 using the mini lathe to make many parts and upgrades. The lathe got a lot of use, however this left me with little time to be able to properly tear it down and give it a maintenance check. In this video I will tear down the lathe, re oil and grease all the parts that need it, and clean any trapped swarf or dust that needs to be removed.

I will also go over a few little mods and upgrades that I have done in the background. Quick ones that would not warrant their own video.

I hope you enjoy the video.
