Always watched folks centre their work but never quite known how to do it accurately. Thanks for the educational video :)

Well done, sir! I'm a Retired Journeyman Mould Maker. Thank for sharing your secret. I'll be using this method from now on in my shop. 👍👍👍

Got it out of the cupboard and dusting it off as we speak. Brilliant instructional video.

Straight away, the best tutorial/refresher since my vocational school days. Top 5 in my experience. Thanks!

You get the public service award for the week. I watched your other videos too and it seemed easy but I got lost. Now I see where I misinterpreted something you said. And a very good key to the method is that you always tighten. Might have to loosen opposite to do that though. I will practice.

Best 4 jaw ‘chook’ vid on KZfaq. Ta. It really is very good and bulletproof!

Thanks John for the video. I've a few projects to do that need the use of a 4 jaw. Your video makes it easier to setup the jaws than the way I've been doing them.

Thank you John, I'm new to using a lathe (only have a little Myford ML10) and have been going round in circles with my four jaw chuck to the point I put it back on the shelf in its box. Broke a tooth on my three jaw (my own fault I was using it right on its limit) yesterday and had to resort to the four jaw to finish the job, your way of explaining was great had it set up in no time. Thanks again, you saved the day!

Videos don't come much clearer than that, great job John.

The best explained and then shown video on the subject I have watched

Wonderful John, you explain this so well......Bravo......Paul

Thanks John really simple nicely done sir

great tip: dragged my four jaw out again...works like a champ. really enjoy your videos.

Thank you for an excellent video.

NICE JOB VERY WELL DONE MATE

I know this is an old post but its brilliant, I’ve seen you set up a 4 jaws dozens of times watching SNNC's and though I must have a go at that somewtime but never really had the need until today, so I did a search on YT and found this video and my does it make setting up simple, very clear brilliant video. Cheers

Brilliant lesson, thanks a million John.

This is the best explanation I ever saw. It is very easy to understand and it works flawlessly.

Nice refresher John - good to see the slight variations between different folk's methods.

Love the video and your accent 😊You saved me.

Thanks John good advice.

thanks John, always enjoy your videos.

Great tips and tricks video John. Very nicely done.

BRILLIANT ... well done ... great shop skills ...

Apart from the four jaw method you demonstrated, I liked the slick intro. Your film making and editing skills are coming along well.

Very good tutorial..

Thanks for posting this video Sir John!

Good lessons on the 4 jaw John! 👍

great video. I never knew how to do that. thanks.

Excellent video, John. If I was still teaching, the kids would watch it for sure. As it is, I've shared the video address with shop teachers still working.

WOW MAN YOU ARE A MACHINE THAT IS FOR ME A PERFECT SET UP!!!

Excellent tutorial sir, very helpful!

Thanks John 👍

Great explanation! Thanks!

Thanks John very helpful

Thanks John, for a very informative video. B

Thanks John.

Great tutorial John. I think I'll pull out one of my 4 jaws and get some practice in. I am one of those that do not use a 4 jaw very often but as I have some steam engine cylinder castings to turn I had better get used to it. best wishes to Debs and yourself. Gary

that's a good system. thanks for showing it.

Great job John, I love your vids, you always do a great job and provide me with good anduseful information. I hope Deb is doing better.

First rate. Thanks John!

Great video John,again I learned a bit more.

going back in time a long way......I really love your intro on this John.......cheers from Florida ....Paul

A high score for zeroing 4 Jaw Chucks. Excellent editing, close ups and vividly clear Dial Gauge views. John managed to expend about the same amount of time using only 1 chuck key, where many other vids use 2. Great job John! 👍Unlike the other guy I have no complaints about what my untrained American ear thinks is as a Scottish Brogue. Wakodahatchee Chris

he said " you clown" ha ha love the vid John! I use my four jaw more and more lately. this is the method I use as well and truly helps speed things up

great video John ,I've just bought myself one

perfect demo, sound and camera angles. now, subtitles please to make it perfect.

Good video! Thanks for posting!!!

Loved this vid, thanks for taking the time to do it :D

Hi John great video I will dig out the 4 jaw tonight and have a play 😀

nice lesson, thanks

Hi John. Yet another excellent video. I know someone else mentioned it earlier, but I believe you should unofficially be crowned '4 jaw chuck challenge winner'. I went back to Bar z's summer bash video of Tom and Adam 4 jaw challenge (cut and paste isn't working at the mo' so search for: 4 jaw showdown oxtoolco vs abom79), and checked Adams time. It was 1:16 whereas yours was an amazing 1:03 AND I feel that it was almost certainly less than 4 tenths as well. Well done for keeping up the British side and showing those Yanks a thing or two. lol (only kidding Tom and Adam).Regards Mark in the Uk

Great video 😮

4:16 mark... It's not just easier to have 2 chuck keys, it's MUCH easier. Once I tried it, I never went back. Thx for the Vid.

Great vid

Wow, so many videos, all in a row! :>))

Efin awesome video.

Always informative john hope the Mrs is doing ok

Good and clear John, but the 1st posting was more entertaining, particularly the language which sounded like my garage does at times.

Are you watching my kitchen !!! As i wrestled my 4 jaw 😭... Sorted 😁

Hi John ! Now you really got the method simplyfied to the extreme ! This is a very fast method for dialing up a workpiece in the 4-jaw - nice and easy to understand ! You would have been the winner of the BarZ summer bash match if you were there - I'm sure ! So, let's forget the video you published sunday ... what a mess and frustrating explanation ;-((

Good video thank you ;-)

Hi mate.You could have won the 4 jaw competition with that.Marcel.

Hi again ! I forgot the mention the bright idea fastening the clock gauge to the toolpost - it stabilizes the clock when re-setting to zero ... no frustrating adjustments needed - bright idea !

goddamn your accent is thick johnny, one hell of a lesson i cant afford a 3 jaw and really been struggling with the 4 jaw thanks for making this vid. thanks from canada my background is welsh we might be related

when it goes so smoooothly one wonders how it can go skew wiff as it did yesterday. before i next use mt 4 jaw i am going to review this vid so i can give your method a try. seems foolproof, though i'm sure i will demonstrate that this fool will be able to screw it up. i also like your tip of using a second center when there is no convenient surface to gage on.

"JOHN FOR 4 JAW KING" Regards Mark in the Uk

Very helpful vid tjanks.. subd

John, Thanks for the great video! You're Briton's version of Adam Booth! If you guys were in a contest, I think it would be very close! Thanks for the video! Have a good one! Dave

You need to challenge Adam next year.

thanks John, will get the finger out and give it a go.

I havent done the hole like that John but I am going to have a play, I use an indicator. Thanks for the video

Watch this with auto-captions. It makes for quite a story.

John, thanks for the video. I’m struggling with the initial part, trying to determine which is the low point. As the needle bounces from left to right or vice-versa how do I know which one is the low point?

the dogs bollocks john

How do you check run out, on a cuboid shaped workpiece, with no hole to push the revolving centre into?

No, Thank you!

makes me want to go out and buy a lathe just so I can practice

YOU COULD HAVE BEATEN BOTH ADAM & TOM !! THE BELT , CROWN & CASH SHOULD BE YOURS :-)

Nice one - I bet you would have won the Abom79 4-jaw challenge :-) (clocked you at about 1:10)

And everything is right with the world! Great video John! Y'all take care... :o) O,,,

hmm, looks like we need to get you out to the colonies for next years 4-jaw faceoff... the belt may be going across the pond :)

7:26 I'm serious, can someone please tell me what he said? I really wanna know

sr you have done a video of 30 minutes..how u made it easy.

7:26 that was not english

thats canny man john scouser trying to be a geordie

I can't understand a word he's saying. It would be helpful if it could be translated into English.

Good save!I use the tailstock live center to get it 'almost there' and finish with a dial indicator (clock).Thanks for posting!
