ATLAS LATHE 4-jaw chuck demo TUBALCAIN

[bond3737]

I had no idea jimmy stewart knew so much about lathes! no offense sir, your video was very informative but you sound so much like him!!!

[Deathgaze27]

You're the man, dude!

[BasementShopGuy]

"tubalcain 2" - ahhh, the early days when you were hungry ;-)

[maliburascal]

Cheers Tubal i have just got a 2nd hnd Taig and have no knowlege of machining!! I followed your tutorial and got to 5 thou in 7 minutes! Brilliant thanks for your videos and "I'll be back".

Regards from Yorkshire U.K. Chris.

[madaboutpix]

thanks for the info!

[dirtyharry793]

Again, another great video! I was trying this out today only using one key. Boy, I spent a lot of time getting things centered. I will make a second key and follow your advice. THANK YOU! You are such a great teacher.

[danahickey41]

TUBALCAIN:

DO YOU HAVE A LISTING OF ALL YOUR VIDEO"S ??? WHERE ARE THEY LISTED ???

THEY ARE GREAT !!!!

THANKS IN ADVANCE

DANA HICKEY

[mrpete222]

@danahickey41 Do a search on tubalcain . They will all come up.

[legatotek]

nice tip for using two keys!

[gracer99]

You are a genius. Your videos explain everything perfectly.  Many thanks!

[LG6327]

hello, I been searching for lathe machines and been looking at a 12x36 craftman lathe but I have also notice that there a few differnt brand names. I am wonder if anyone knows whats the differences between 12x36 Atlas, 12x36 craftsman and a 12x36 craftsman commerical. I wish to know whats the fair price for one of these lathe in good working condition.

[mrpete222]

@LG6327 These are all the same lathe--some models may not have the gear box. 600 to 800 is a fair price.

[CncObsession]

Once again I have used one of the techniques gleaned from your videos. All I can say is wow, that is easy. The results show it too. I was always thinking the 4 jaw was intimidating, well I got over it and tried your method. It was easy and I dont see a reason to go back to the 3 jaw. It couldnt take but 2-3 minutes to get it all set up correctly, especially once I found out there were witness marks on my D1-4 pins! LOL ( chuck kept coming loose).

[RonHofer]

Sir,

I want to thank you for the many of us out there who had no real training in machining but, for whatever reason, tried to understand it at a late date. I'm a former English teacher, turned law professor, who tries to machine metal in my retirement. You are an extremely patient, gentle, and effective teacher, and I very much admire your abilities, both as a machinist and a teacher. Thank you.

Ron Hofer

[OneAwesome8701]

I like this very much, tomorrow our teacher told us to set up individually a round bar in a 4 jaw chuck, I hope I would set it up faster like you did, if not I will get a failing grade XD

[doorguru168888]

Thanks for the explaination. I understand now..

Another question: I take it from your statement that Atlas only made light duty lathes and none of them were considered Industrial, Right? I know your videos are more of a technical nature and not about the lathes themselves, so you might not be able to answer this, but please do so if you can. You are still a genius in my book : ) Thanks Again.

[mrpete222]

I would say its fairly light duty. Remember, everything about an Atlas lathe is light duty compared to heavy duty industrial models.

[doorguru168888]

Hi, Tubalcain, Is the 8" chuck in the video considered light duty? Friends in the forum are now convinced that it's not for wood, but are saying it is only for light work:

Beginning of Quote

"The 4 jaw pictured, is considered a light duty chuck. Not a bad thing for lighter work. Heavy duty 8" chucks would be solid all the way through the body and pretty heavy in weight. "

End of Quote

I know I should just let it pass, But I want to convince them that they are wrong. Thanks Again

[doorguru168888]

Thanks for making all the cool, informative videos available to us beginners. I have a question.. I just bought a new old stock, 8" 4 jaw chuck EXACTLY like the one in the video.. Everyone is telling me that due to it's hollow back, it is made specifically for wood and not for metal. Could you please confirm that the chuck in the video is in fact made for a metal ? I even showed them the original Sears catalog from back in the early 70's and they are still not convinced..

[mrpete222]

@doorguru168888 You are right--not them. All 4 jaws are made that way. Imagine how heavy they would be if solid. Also--at the foundry castings must be made fairly thin to reduce shrinkage as the molten iron cools.

[bangzilla]

i love that you super experience machinists are posting tips on youtube

[MGARestoration]

I stumbled across your machine videos and found them totally riviting. I have sat for hours watching you teach and demostrate machining. I have an 1885 Seneca Falls lathe and have updated it to run on 120 volt single phase with multiple speeds and reverse. I am currently looking for a small mill and I will start casting and machining my own steam engine. THANK YOU for all you do!!

Could you do a demo on centering a piece of square stock in a 4 jaw chuck?

[hbfowler]

Good day Tubalcain,i just acquired a 1940 1950ish empire 6.5x40" mk2 lathe,i am a beginner and am interested in learning the tricks of the trade, i find your videos very informative,but there are handles and dials on the headstock and carriage that i cant figure out , i dont want to engage anything at the wrong time and "crash" it,would you have knowledge of this type lathe or can you direct me to someone that has?i would like to have a Manuel of some kind,i think that it would help me a lot .

[mrpete222]

@hbfowler Sorry, not familiar with an empire lathe. See if you can find one on ebay or do a google search.

[fgleich]

How would you center a piece of square stock or something that isn't round ? Would you use some cylindrical stock that has the same diameter as the square stock or ? great vid, btw

[newcomer9747]

Hi, I'm using the same method too and have since love using 4 jaws over 3 jaws. The only gripe is it's a tad difficult to tighten all 4 clamps without upsetting the dial indicator a little. How do you tighten the the jaws without upsetting the dial?

[mrpete222]

@newcomer9747 Just keep lightlt tightening them one by one. Go around about 4 times--each time getting slightly tighter

[man4Sam]

I just inherited an Atlas Model 618, with Starrett gauges etc, and I had no way of learning how to use it except for your videos. Thank you for sharing your wisdom with the rest of us! INVALUABLE! Please post more, belt maintenance and adjustment, power wiring to handle the heavy current load, mounting etc would all be helpful. Thanks again!

[recklessjim]

Ive been watching your videos for two nights now and love them! It's hard to get practical knowledge anywhere so thank you.

[sandwon]

Thank You I am take a Class for Machine Tool an your Video's have helped Me So Much.

God Bless You

[1TEKTRON1]

Cool, Thanks 4 the tips.

[trailbusterbrute]

Your videos are amazing and among the best on the web. This video has been very valuable to me as I have struggled and frustrated over the 4 jaw chuck on my TH54 Atlas for quite while now. A 3 jaw chuck is quite an expense and you have convinced me that I don't need one as it is only for convenience. Keep posting. I am learning so much from you.

[jben839]

Hi there I have a 36" Atlas - which I think this is. I am going to put a 4 jaw 8" chuck onto it. I am worried the one I have is too heavy - 40lbs. I can get a lighter 30lbs chuck - would that be ok? Cheers

[mrpete222]

@jben839 Yes--8" is good, and get the lighter one

[liaschinko]

@jben839

hi all out there, my cuation for this vidios, is how the masters vidio are working in the 3 th garges , sorry about languedges )

[meyeahright]

Anyone ever tell you that you sound a little like Jimmy Stewart? Good vid anyway.

[tinsmithpaul]

TINSMITHPAUL;Very informative,never thought of using two keys,will watch your other videos,thanksfor sharing your knowledge.

[PortableQRP]

Hmmm Tubalcain, interesting word, what does it mean? Do you ever travel east?

[mrpete222]

@PortableQRP From the book of GENESIS.

[93rev2sev]

MrPete222, I've become a huge fan. I'm just learning some basics lately and I'd really like to see how one would center a workpiece in a rotary table for the mill. I greatly appreciate you sharing your expertise.

[papouxs]

yo estudio mecanica de produccion , es muy interesante el video

saludos desde Peru :)

[gohuskies583]

Ive got a small craftsman 6" a 109 lathe. I dont beleive I have the circles cut into the face of the chuck. Could I cut these into the check face with an ordinary cutter? Not sure if the chuck is hardended or not. Will the cutter break when it goes across the 4 grooves in the chuck.

[mrpete222]

It should be soft enough to cut grooves. Check with a file. I never saw a 4 jaw without the circles.

[SupersawLead]

Thank you so much for this video :)

[steppapajon]

Thank you for taking the time to post this video. I used a four jaw chuck for the first time yesterday and struggled with it at first. This video helps a lot.

[wackedoutdude]

At last an easy way to set a 4 jaw. Awsome vid. I used to hate the 4 jaw because of the set up time but this trick sorts it no sweat.

[johno2355]

I like all your videos, I have seen about 6 and I wish I lived next door to you, I guess you tube is a pretty good start. bye for now.

[capriracer351]

Good information.

I use a similar method when setting the precise zero voltage output of an inclinometer when it is set at perfect zero taper on the continuous casters that I wire upon refurbishment for the steel mills.

I thought about it a while and used the locking screw to oppose the jacking screw until I achieved a precise zero voltage output.

When I started doing it this way, no one would believe I was able to do it that quickly until I showed them in person. Thank you for the videos

[makedoandmend2]

Excellent advice i have found out what a tricky job it is to do with just one chuck key

[tinysd]

Thank you! The two key method is a great idea.

[delayj]

4 jaw is more rigid and accurate than a 3 jaw.

[moto9ll]

why would anyone want to use a chuck like that if you have to dial it in every time you take something out of it?

[vlmarshall]

Sometimes you want to turn a part OFF center - like a cam or crankshaft, or hold square or oddly-shaped parts.  A 4-jaw lets you do those things easily.

[moto9ll]

i see.....after watch'n your vids I can tell your are a ball of knowledge!

[machinistguide]

Also you can get your part to run more true in a 4 jaw if your 3 jaw is running out .002 and you turn the part you will be off center .002

[OUMagMan]

Holy Moly - how simple, how clever! To think I used to dread using my 4-jaw! I think I'll go right up and give this a try!

THANKS!!

[DrFrankensteam]

Great Video, I've watched it a couple of times as I am new to machining for a hobby. I just recently purchased a 4 jaw. I was wondering if you can do a demo on centering a square bar in a 4 jaw please! Thank you!

[mrpete222]

I'll try to do one in the future. In the mean time, buy a copy (on ebay) of the SOUTH BEND LATHE booklet entitled "How to Run a Lathe". Its old, but still the best.

[DrFrankensteam]

Thank you! I actually think I have that book on CD somewhere, but forgot I owned it! Thanks again.

[AlbequerqeTurkey]

Great video. thanks for sharing

[latheworks]

That's the way to go! Very well explained.

Thx!

[cambo61]

Nice job. Thanks for posting this vid.
