Damn! You have just made my life much easier! Thanks for sharing.

I just bought a four jaw... Fought with it for 1-1/2 hours. I was ready to carefully remove it from the lathe and throw it thru a wall. Glad I watched your video. After learning your two key trick, it took me 3 minutes to get it dead on. Thanks.

Thank you for sharing your method of using a 4 Jaw Chuck. You made it look easy and gave a great presentation on what to do.

What a great informative video. I replayed your previous one several times but your method was a little difficult to follow...this one is crystal clear. Thanks for this really useful video. I have always been in awe of Adam's insanely fast 4 jaw alignment...now we can all get close

Yes sir! Thank you. Way better than the others I watched.

Thanks, i have been spending 15 min or more to set my chuck

Love these videos. That four jaw is a bear to adjust, but this video is great. Thanks for sharing again...Ken

You just made my hobby a lot more fun. Thanks.

Simple and straightforward method👍👍

Thank you for an excellent video, this has explained very clearly the method used, you now have another subscriber and I am on my way to the garage now to make another chuck key, regards Doc Cox.

Great method. Not bad at all.... Have to design that second key for a mini lathe.

Great job explaining centering on the four jaw. Thank you :-)

Thanks for the video, very help to a newbie lathe owner such as myself.

Nicely explained. Great video.

Ta, very informative, looking at a lathe the now, will go for the 4 jaw.

An excellent very informative video, very clear instructions, regards Doc Cox.

Very cool,willsave alot of time in my shop!

Great video young man!

Nice presentation Greg. :-)

Awesome, you've got a new subscriber.

Great technique

Great one chap i just spent 25 mins playing , watched your vid and 5 mins i am sure it will get better once i get / make a second chuck key

Thanks for sharing...

Mast 4 jaw chuck seting

Can you do the same demonstration with square stock, please? Thank you.

great tip.

great explanation. I inherited an old atlas craftsman, with a four jaw chuck. I can center and cut round stock, but notice the jaws are worn. "Bell-mouthed"?... I've heard it called... where they bite in the back, inside the chuck first...and I can see light under the jaws in the front. Any ramnifications of this? Should I try to correct this... or is it a real problem? How can I fix this if I need to?

good tip, thanks

thanks for sharing,

This was a good method, very easy to get the hang of it, unfortunately I never got my piece truly indicated. I had been going mad and running in circles chasing my own tail on this and that's why I started to look at videos like this. But ehhhh, now I see that two of the chuck jaws tighten at the back first and the shaft I was using was moving a whole lot regardless of how much pressure I put on it. Sigh.

Using rings or circles cut into the face of Chuck, lining up the same places on all jaws, this will get you very close this method can be used on square as well as rectangle shapes....they were put in during the making of Chuck for a reason... bell mouth jaws can be reground in chuck with use of ring clamped on i.d.,,or taken off and surface ground using form wnheel

See those inscribed circles in a face of a chuck. They are used as a quick reference marks. You don't need a ruler

❤ the job

You are certainly right about the chuck. The four jaw is the only way to be sure youi are dead on. My 3 jaw chuck has nearly 15 thousandths of run out. Thanks for the video.

Thanks a lot.

Cool video so when are you going up against the grand Master Abom lol

I don't bother scaling it in before hand... just doesn't seem necessary? I do use the 1/2 method for dialing it in though.

Hi, I have one doubt. Can you please explain in 4.46 minutes you told that lowest point you are setting zero. But that time dial gauge was showing 59. You turned the dial and made it 0. Plz explain me. I'm a student and trying to learn lathe machine

Great video. This must be the fastest centering of a 4 jaw I've seen, Okey, ABoom79 is fast but if he would jump up and sit on the lathe bed he could get lot faster, like You.

Going to give this a try! Thanks

awsome ty

thankyou

Please what's the name of the instrument with the scale

is that a 6" chuck you got ?

Now I wish I had a larger lathe.. and another chuck key..

happy halloween

Not bad, but I still prefer to do it the Abom79 way. It only takes like 4 seconds to get it to .0001 You should give it a try!

That chuck has a center hole Correct, why not make a Standard that fits in the hole and make the first adjustment off the standard. Set up a hard pin for fine adjustment. just saying

You’re a having a laugh

What a pain will stick to 3 Jaw :-)

You lost me as soon as you clamped that magnetic base to the precision ground ways on your lathe. No professional would ever do that. And no one watching your video should ever do that.
