I love how the entire video is full of super high precision then it ends with "Hulk smash!" :)
OK...a lot of people won't get this, but my deepest thanks for doing such a simple project Well. Anybody can put an Internal thread and use it for collets. The people who catch my attention are the ones who make every machining effort to be the best expression of itself.
Nice Job!! Well Done!!!😊😊😊😊😊
Other videos can wait.
What a nice break from applying for jobs. This made my evening.
That press fit at the end is especially satifying. Thanks Chris, but miss hearing your mellow Ozzie narration on these Clips series videos!
Now I know how a collet lathe works, except for the drawbar. Thanks ! anytime I learn something new , it’s a good day for me
Beautiful workmanship. As always.
Thanks!
Cheers mate :)
More impressive work amazing job 👍🏻👍🏻👍🏻👍🏻
Doing a similiar project for a grinding spindle. Just used a er16 holder with high accuracy, and build some bearings around it.
The 3C collet , big brother to my 6AT collets .
Very nice work mister.
Watched the whole thing to see what a draw tube is for. Still don't know.
A draw tube is for pulling on a collet and "drawing" it into a taper so it grips whatever's inside the collet. On a lathe you need a draw tube long enough to extend through the headstock (where all the gears are) and protrude out the back. There's usually a flange and some kind of bearing on the back which a lever pushes/pulls against. This way you can open and close the collet while the lathe is running.
The draw tube attaches to Collett and will pull them into(connect to) the head stock on a lathe.
Totally tubular man!
Thanks for sharing 👍
I'd love to see a video of what equipment you use to film these. How and why you film them the way you do? Basically, the what, why, when, who and how of making them.
The doobley-doo has all the links of his equipment. Get that, and copy his style. Done!
That is a long ream. Good lord
I'm a simple man. I see a Clickspring video, I watch it.
Look in the video description for answers to your questions.
Shiny! 👍
Next installment...making covers for your ways...🤣
Nice build. But it would have been even nicer to show it being set up and used.
How or when do you decide to use the 3 jaw chuck versus a collet style holder??
Generally, a collet will be suitable if the work is being re-chucked for more cutting & reasonably good concentricity with the OD or just-turned features is a priority. If the features are all being turned in one sitting, perhaps the convenience of the 3-jaw might be preferred. Need dialled in centering? perhaps the 4-jaw. Planning a set of must-be-concentric features at both ends? Perhaps between centers will be best. Need to protect the OD surface finish of a part? Perhaps a better grip than the jawed chucks? Again, possibly collets. Many factors play into the decision of lathe workholding. It will depend on the available tools, what the part requires, and the creative whim of the turner - Cheers :)
😎👍
👍😎
Why did you ream the inside?
Because he can 🤣
So it looks really good where you can't see it!
Why have you started doing that TikTok-esque staccato rapid-fire jump-cut editing lately (like at around 2:10, for example?)
Maybe speed through turning the equipment over instead of cutting it out?
Out of interest, what are the clamps for? - To add additional weight to help with balance? 🤔
Are you asking about the drive dogs he used?
One drive dog clamped to the dead center which spins with the chuck, the other drive dog clamped to the workpiece and being driven by the first drive dog. 🤔
If you mean the ones that you first see at 1:57, it's as mr.b2232 said. Without them, you couldn't transfer enough torque to the work piece when it's only held between two pointy centers.
His drive dog seems to be not big enough, so he bridged this with 2
Drive, dog, and let's gitatta here.
I am not worthy
Wow you made a tube. We'll put a picture of it on the refrigerator. 🙄
yeah no example or explanation what a draw tube does, title says "for the lathe," should it say "on the lathe" ?
@@jyvben1520 I'm pretty sure it's both (for/on). That said, I have no idea what a draw tube is.
@@steamer2k319 It goes through the body of the lathe, so you can use it to pull a collet back against the collet chuck and get a better hold on a piece you're turning.
