I have a high dollar Pratt n Bernerd 3 jaw that is vey accurate and repeats nicely. I don’t have to use the four very often if at all. But this video is well done and it’s nice to hear a fellow machinist that knows what he’s talking about and knows how to communicate.. rare these days.
Thank you for showing this vid I have seen it done before but not up close or explained! A very good and informative video I have subscribed , I have just got a new SC6 and I am in the process of aligning it up, thank you once again John Kinnane Tasmania Australia
nice the dial indicator is a must for hand milling machines as a point of reference and to gage any play in the material or equipment... i think it is an cool simple measuring device the makes you have really perfect measurements with out even really measuring
very good video. i when i saw you use the rule against the dead center i thought why have i never thought of that. old dogs can learn new tricks. thank you
Your Videos are really good for beginners and trainees . Im a Trained lathe Operator and searching for a channel like yours in my language. Keep up the good work. Greetings from germany.
Great video. I prefer to use the 4 jaw chuck as I can get things lined up much better than the 3 jaw chuck. I normally just use the circles to line things up. Thanks for sharing.
There's also the possibility that the 'straight' bar stock isn't as straight as it's supposed to be. If the length hasn't been stored correctly there's always a chance that it has 'settled' and bent. As much as possible I keep my small stock of bar in the house and stored on end or flat on the floor (depending on length) to reduce warping. I do this for most of my steel stock, round square, angle, etc, to keep the _rust monster_ away! The rest is -scrap- ... I mean projects yet to be started!
Thank you for sharing. It's the same way I use to. But my 4 jaw chuck has worse quality than yours so sometimes it's difficult to feel the just tight on the wrench to reach a 0,01/0,03 mm runout. Anyway to be in that range is enough for most jobs.
curious for chucks of different sizes do they all usually have the same jaws that you screw down into the chuck or is there different jaws you can buy. Not sure if different type of jaws for chucks are required to hold different things or is it usually one jaw type fits all for a specific chuck (lathe chuck that is )
+sam111880 Very basically Sam, there are two types...three jaw (all working together) and four jaw (all working separately). There are soft jaws also (you form) typically found on CNC lathes. Having said all that there will be some other setup but these are the most common in my experience.
@@machiningmoments this answers all my questions on how yo dial the chuck. I am a trainee and will be train to manual Lathe. Thanks a lot. I subscribed for more learning videos
Thanks for the videos. Say I wanted to face a part, then center drill it in preparation for live center tail support. Should this operation be done with minimal stick out, or should you face/center drill close to the chuck, then pull the work out to the desired length of stick out for turning (with tail support) and then re-dial in the 4 jaw chuck? Basically looking to see if it is necessary to dial in the 4 jaw chuck twice during that sort of operation.
Right right. So generally you would dial in your piece. Face, center drill. Pull work piece out to desired stick out. Re-dial in the 4 jaw. Then support with the tail stock. Right?@@machiningmoments
It would be difficult to do in a 4 jaw. If the chuck had accurate jaws that would help. Also I would not hang 3/8" or less diameter out very far from the chuck.
Help, I’m new to lathes, I have a 4 jaw chuck and spend a lot of time adjusting and if I need to turn the stock around I cannot seam to get it to cut even on the other side. Should I just use a self centering chuck or keep at working out the adjustable chuck? Thanks for the video.
If you are new to lathes you will likely find a 4 jaw chuck challenging. A 3 jaw is a lot easier but if you persevere the 4 jaw is more versatile. Are you using a dial indicator? You will need one with a 4 jaw.
I just got my dial indicator set-up, I used your suggestion on your video, I got it within .003 in about 10 minutes. My turning came out great, your awesome.
@@machiningmoments any tips because I’m an apprentice fitter and turner and most my jobs are rough surface I have a hard time trying to true up a job boss tellling me I’m taking to long
You tightened the jaws up too early. Don’t get them so tight to start with. I presume you were going to centre the end? As this was a long piece to turn unsupported. Taking into account this video was to show how to clock - up in a 4 jaw you never actually did that. Your chuck was naturally holding the work at an angle so it is out. Only packing shins will let you hold it tight and parallel so you can centre the end and support it in a revolving centre. Was a bit misleading to anyone starting out.

+sam111880 It definitely helps! Thanks for commenting.
Great job with the tutorial, fella. Great job.
Thank you, glad you stopped by.
Great video tutorial. Thanks for uploading young man!
My pleasure...not sure about the young man part! :)
excellent video great job for beginners like me,I'm truly thankful I finally understand how to do it rite

Thank you - I really need this information!
Glad it helped.

Very good
the first time doing this took me almost 30 mins to do it correctly. After trying and trying again, i'm able to dial it in within 10 mins max.
It's tricky and becomes easier with practice. Thank you for watching.

The rule of thumb is no more than 3 times the diameter sticking out of the chuck unsupported.

And if that bar was really 3/8" or less in diameter, would you be tapping on it ? Is there an alternative way to aleviate the wobbling ? tnx.

I will plan to get a three chuck. I’m kind of limited because I have a taig lathe.
Thank you.
@@andrewk.3902 You may be able to use the backing plate from your 4 jaw.

@@andrewk.3902 Good for You! If you get comfortable with the 4 jaw I think you will like it better than a 3 jaw.
How do you use a dial indicator on rough surface like how do you true up the job of the dial just keeps flicking around
Years of practice. :)

I've seen grown men reduced to tears clocking a 4 Jaw. If setting up on a Forging, don't be afraid of using a length of pipe to the chuck key!!
It takes practice. Careful with the pipe it can crack the chuck.
Awesome thank you !! What about dialing in a square piece in a 4-jaw…

As a novice lathe user, this video is very useful, but I think a 4 jaw chuck is too complicated for anything I intend to do.
It definitely takes more time to setup. If you ever worry that the work may come out of the 3-jaw chuck, this is the go to chuck.
4 jaw allows extreme accuracy, and you can bore off the object's center.
