7x14 Mini Lathe - 4 jaw chuck upgrade

NOTE: I have no experience with machining, these are videos of my very first attempts. Enjoy watching my mistakes, but nothing I'm doing in these videos is correct.

Lessons
- Those tool sizes matter, too big and you won't be able to set the height
- Jaws crush threads of bolts easier than I thought
- A cutoff tool seems handy

That visual effect at the end when you are time lapsing is absolutely psychedelic. Cool video, brother. Thanks!

Do you have a link to the 4 Jaw you bought? Also a suggestion is to AC glue the threads in nits then use the nuts as work holding, when you want it off soak in acetone to dissolve the glue.

You can buy a quantity of that bolts from "Arc Euro Trade", sorry now they are out from Europe ( the company is based in England ), so buying is not so "straight forward" as before. I bought a couple of dozen, after having overtight the original bolts ( and happily i was able to turn them off of the chuck ... ).
Don't you see how your bolts are not ALL threated ? A common screw is not the ideal solution, even if cutted at right lenght. And also, are you sure to change the bolts from a three jaw chuck to the four jaws chuck and reverse, every time you'll have to change chuck ?
Believe me, changing chuck is not so uncommon as you can think now, at the beginning of your lathe experience.

Brother man before using any machine go and get some training first, because you look like you will harm yourself 😂

If the tool was at the correct height the screw was hanging out of the chuck too far, allowing deflection!

The intent of this video was good. However, watching this video scared the crap outta me, for the machine operator. I have this same machine for small projects at home. I’m not a professional machinist, I had some training back in high school, back in the day when they had shop classes. In our metal shop we had, no pun intended, “old school” Bridgeport mills and lathes. I still remember watching the safety films about what happens if the setup is incorrect, the wrong cutting tool is used, LOOSE MATERIAL flying outta the chuck, inserting tools on any part of the machine while it is in operation and using substandard hardware on the machine to replace or repair parts (E.G. using grade 2.2 or grade 5 bolts machined down to make stud bolts that can fit into the chuck that should at a minimum be grade 8 or higher stud bolts)… I also remember the shop teacher saying every morning “15 minutes of a good equipment inspection and proper setup will save time and money in screwed up equipment and project materials, not to mention a trip to the hospital or mortuary”. I ain’t hatin, I’m just sayin.

Im cringing over the screw being able to move that much

You are cutting more on the return pass whis show you lathe is bad setup now. You have too much sloppyness in your setup End Will change machine big time if fixed
