About

My workshop is in my kitchen, so I have very little space. As a result I have a very small lathe, but my lathe and I don't let that stop us from having a go at some tricky projects. "This channel is the Mr. Rogers Neighbourhood of machining" -- Dustin Masters

Video Description

I recently bought a new Chinese CJ0618 7x12 Mini Lathe, very similar to the classic Sieg C2 lathe which is sold under different names all over the world. I have a few plans for this lathe, but the main reason for buying it was to finally answer all the questions I get asking whether the Proxxon PD 250/e is worth the money, or if a Chinese lathe is a better deal. In this video I'm trying to fix the tailstock so it properly fits to the bed, to make it stable when in use and to stop it causing wear to the bed surface. None of this video should be taken as educational, it's just a record of what I did while I was learning for myself. Don't do what I say, or what I do. If you want to use the same learning resources I did, check out the video links below.
