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.
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.
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.
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
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!
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
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
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
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 ;-((
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
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 !
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
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.
+kempy666999 Perhaps. But doing it for a video with unlimited takes, using your own equipment in your own quiet shop is a much different thing than doing a single try in a 104 F (40 C) shop, using a lathe, chuck, and indicator that all belong to someone else, while scores of machinists are looking over your shoulder and making noise.
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?
