There are many comments here on bad practises, but many of them are also recommending bad practises. The one I hate hearing and seeing the most is recommendations to wear gloves. NO, NO, NO!! No gloves, jewelry, watches sleeves. Nothing that can grab and pull your hand into the machine. Much better to get a scratch from swarf rather than lose a finger.
The simplest solution for outside turning on a diameter that pushes the limits of your lathe is a boring bar, mounted backward in the tool holder, with the tool post rotated 180° from the usual orientation. That is, if you have a moderately long boring bar.
A thing I always watch for when someone is using a drill press is table flex. Yours flexed a lot. You need to use an old scissors jack to support the table so it remains true to the drill or whatever you are using. It's what I do if using any sort of force.
Although there is a lot of room for criticism, but the fact that you were able to "machine something" that large on a mini-lathe is very commendable. This is good video for those garage-shop engineers to see that "it can be done". I graduated from my home garage to an industrial shop with bigger toys, but I remember the days with wanting or needing to do big things with small toys.
Im liking your videos, a good engineer always evaluates their work at the end of each job thats how we learn and move on. Avoid these armchair engineer’s negative comments. Keep bringing the videos in. They are quality!
Hi mate just wanted to say " thanks so much for your! time & efforts with all your videos!!! " It's awesome helping us without a clue 😂 & learning - after watching how well you re-built your lathe with all the problems you had gave me confidence to get one ( especially with the hit n miss of what you might receive?) , I was saving for a Siege mill lathe combo but it's way too small & last night looking on local ads - finally found one & was the same one you have so I bought this one instead - now I'm just watching all your videos again from strip down through 👍 thanks again & please keep up the great work & projects you do!! It helps soo much!!
I appreciate this video. I have a very similar sized disk of S7 I was not able to figure out how to use my Sieg lathe to work, but your idea of using a bolt in a center hole as the chuck mount point, that is a good way around the size limitation of a 3" or 4" chuck.

just a friendly tip use a vice and never try and remove swarf with your hands and when drilling or machining on the lathe and make sure its stopped before you do
you used a 3d printer to find the centre of round stock 0.0, overkill i love it hahaha.
It's always good to see how others manipulate their mini lathe to make it work, I learned a couple of tricks from watching this video.thank you for making it .
It is said that "There are many ways to skin a cat" and I thoroughly enjoyed watching your way!

there are many ways you can use to find the center. one was to draw a line across from 8-10 different angles from edge to edge and the intersection in the middle is the center. i have used that for years and never had an issue. just something to help ya in the future for faster results is all. but good work!
Curious: which do you find more useful, the ADDITIVE process of 3-D printing, or the subtractive process of lathing?
Look you came up with a usable solution to get what you wanted. Excellent, this is why we own these amazingly useful machines.
Nice workaround on a small lathe like that 👍🏼
i actually just bought one of these china lathes to make bushings and other spacers for our drift cars. Your videos have helped a ton! I cant wait for mine to come in, and start working with it. The way the motor is mounted still scares me though... haha. good videos man, keep uploading!
I recently bought the same Lathe as you have. I also had a lot of trouble...straight outta the crate!! I have learned a lot about my machine from watching your videos, so thank you for sharing. I did notice in this video that when you were facing the part that there seem to be ridges in the finish? I have the same problem with my Lathe...very poor ridged finishes. I upgraded to all metal gears and tapered roller bearings and still have the same results.
