Advance METAL LATHE- boring steady rest facing

[crapforbreakfast]

Unbelievable.

[acidbreakk]

your must not work with the ring on lathe machine.ring is dangerous..safety first.

[gomezpiro]

That is very dangerous teacher !

[TheSavumato]

was it straight in any part of this video? it shouldnt say tsih tsih tsih tsih tsih

[Volvo745T]

Guys: Note if you continue to drop in and crap all over these videos, people won't share their information. This gentlemen owes us nothing ... at the very least be respectful in your comments.

[Squarerig]

Excellent!

[hettygreene]

Great instructional video!

[ThePoseidon211]

when boring you want on center or a little above not below cause you could hit the bottom of the part. but your just going to send some bull shit comment plus your not a safe machinist. get ready to loose a arm or finger

[bahhv2]

No cotton overalls, safety glasses conforming to whatever country your in, and no steel caps?

I would've been shot if i dressed up as you...not really...but still

[UpcomingJedi]

@bahhv2 In my class, the offender would face a firing squad where he stands at the wall and the class gets 2 shots each with a tennis ball. I imagine thats not allowed anymore.:(

[chasehunter810]

I like the students shirt it says beer lol

[karlhrdylicka]

De burr the inside of the pipe and use a tube center .

[jrolands]

@karlhrdylick

If the saw doesn't cut straight the tube center would just make the alignment worse. An inside spider attachment however would give the ability to dial it in before cutting. However I'm sure the teacher in this case has considered the application and felt that this setup was sufficient, even though it's not ideal.

[geegoe1]

or files they will and have killed todaly posted under geegoe that thewife sorry derectit here

[geegoe1]

grabb a good machine from the 50s and check out of round on the outside with a magnetic base correctly spin that bugger to within a thousanth then carry that within 3thousanth max run out to64" bump youre easy rest dead zero the info on how to find that costs forth gen machinest in training, I' ll send pics. When you spend time on the end of a bench from grasshopper time u learn sevreral things .

One of the first thing my dad taught me was chinees junk machine aint worth the time of day

[topcat320]

You are talking about safety in the video yet you are wearing rings, watch, and sleeves. All can be caught and pull you into the lathe!!!!!!!

Not good practice.

[DieselCrawler86]

I would have liked to seen you face both ends and and turn it on centers then bore it.

[ed563]

how come it spinning in reverse? whats the difference with the direction the chuck spins?

[Rogue7892]

@ed563 it's not spinning in reverse, the cutting tools only work in 1 direction

[RandyCOG3]

Maybe the ideal student (for the video) wouldn't have "BEER" on his shirt... I'm jus' sayin'..

[quadzilla26b]

AND ALSO YOU WERE TALKING ABOUT KEEPING It SAFE? WHY DNT U PUT A LIVE CENTRE ON THE END OF? THEN YOU KNOW IT WONT GO ANYWHERE? ...just sayING

[MOREENGINEERING]

We require a clearance under the cutting edge to allow the cutting edge to penitrate into the material without undue friction or resistance. If we set the tool on centre height the when we get the deflection, we will reduce the clearnace under the cutting edge.

[MOREENGINEERING]

I note that "CNC addict" mentioned that he believed that the boring bar should be set up ABOVE centre. I concur with this practice. Boring bars as a rule are less rigid than most external turning tools, and as such means that once the cutting edge comes in contact with the material there is a potential for a deflection. Some of which will be downward.

[M1ST3RHYDE]

As for the rollers what if youy have air jets piped next to it so the chips wont gaul up your work?

Thanks for the info.

[JustWonderingHowToDo]

What is a good size for a spindle hole? I know the bigger the better but what is a normal, decent size hole?

[CNCAddict]

Nice video. One comment though is that I believe boring bars should be above center for stability, not below.

[FreePizza007]

Pardon my ignorance but ... Y not just stick it in weak acid. Will clean up the rust?

[wolfie83]

@FreePizza007 the point of machining is not to clean up rust, its to remove stock to a desired size...the skim on the outside is because tube is never perfectly round unless you pay out the ass for ground calibrated tube, and oval tube wont run very good in a steady.

[newcomer9747]

You really should remove this video for safety's reason. The apprentice shouldn't be wearing long sleeves at all!

[Luciferstyles666]

hi, near the end , why did you not slide the bar back after you marked it, that way no evbration would not occour,what reason to use that pipe for automotive it would rust, from what you have said about the pipe, is it test time, thank you for the view.

[william4art]

If you really wanted to make quality you would indicate that part concentric as possible, then machine a minimal depth true surface for 3 or 4 inches like he did..then turn the piece so the jaws are holding a true concentric o.d.. by doing this it reduces compounding tolerances.. someone should post geometric dimensioning and tolerancing videos on here.. work from junk surfaces machine junk surfaces.. quickly create true surfaces to work from... always get quality surfaces..and be safer too!!!

[TheALONE25]

isnt if you dont use the right rpm causes i think more accident...?????

[janovewaldner1]

Hi, I'd like to know the name of the "saw machine" that appears at the beginning of the video, the one used for cutting the pipe.

Thanks in advance.

[Srbija575]

@janovewaldner1 Just in case no one answered your question- it is called a "power hacksaw"; there were various manufacturers. Don't know if they are still made these days as metal cutting band saws are more popular for this task now.

[TYUF786]

well done video

[Icutmetal]

Any time you use a roller-type steady rest, you should sheild the steady rest from chips with a piece of cardboard- cut a hole in the center the same size as your pipe and tie it to the frame. Catch a chip in the roller and there goes your finish...and sometimes the bearing race.

[ray5961]

he has some nice videos on lathes, but as mentioned below, the ring, watch and long sleeves need to go for safety reasons - like if you enjoy having 10 fingers. When I was a kid, I had a drill press grab what I was working on and spin around the work and the vice - it caught my sleeve and pulled me into the drill press - not fun! I barely got to the emergency stop in time; dug into my skin and cut me up a bit. Happened in the blink of an eye - very scary, so be safe out there!

[filaso21]

long sleeves ring watch , my teacher wouldve kicked me out the shop lol

[wolfie83]

@filaso21 i've worked shops that would give a written warning then fire you for not having sleeves rolled down...I quit after it got ridiculously unsafe with what they wanted from the employees. That said, you can safely machine with long sleeves...shops get cold in winter

I have gotten a laugh from the comments...I've found after doing 1 year pre apprenticeship, 4 years in an apprenticeship, and 4 years post trade that there is a million ways to get the job done.

[shipboy08]

@filaso21 Yeah, thats pretty dang dangerous... one snag, he'll get pulled into that lathe in a second.

[shipboy08]

@filaso21 Yeah, that's pretty dang dangerous. One snag and he'll be pulled into that thing in a second...

[caddjunkie]

Safety First.. Shop teacher should know not to have a ring and a wrist watch on.. Poor example..

RIP mr.basso

[patinggoy16]

R.I.P Mr.Basso!!! :(

[hutchisonengineer]

critic the guys good teaching? you clearly know little about speeds. i'd like to see your video with added speed, i need a good laugh. i think you are doing a stirling job teaching the students, keep it up.

[chipmaker2]

A quicker, better, and safer way to cut the O.D. is to grab the inside of the pipe with the 3 jaw chuck. Tap the outboard running true as you did and then make your O.D. cut near the chuck.

[hutchisonengineer]

it'l push the tube out of round the way you explain, it will also have a smaller contact area for grip. if he chucks external he has spread the load . then use a boss with a shoulder down the end bore with a live centre for axial pressure application into the face of the chuck.

[ytmachx]

That's the way I do it! Just a piece of aluminum hammered into the end and center drilled lightly. Works great and it's quick and accurate!

[noeliscool]

00:25 better known as telescoping gauge

[Tommiclio]

Not enough spindle speed or drive...

its not a hard metal dont fear it!

[Vantechmetalwork]

The feeds and speeds= STUDENT SAFETY- It is best to be conservative in this approach. Crashes happen when students do not have experience on processes. Several other factors are tool geometry and radius of the insert, this dictates speed. In order to reduce vibration I have slowed the speed and reduced the feed. I need a good finish or the turned steady rest area would damage the roller bearings. Similarily, the bore begins with an intermittent cut because of the weld seem. Thanks

[wrobinson7]

Excellent vid. Thanks. The shop I work for does custom tooling and machine building, but our specialty is repair and new build of hydraulic cylinders. Trust me, we use a steady rest, a lot. What these young "experts" that comment don't get, is that when it comes to work like this, slow and "steady" wins the race.

[Tommiclio]

@Vantechmetalwork Student safety...He's wearing a T-shirt.......thats hanging out and could catch....yes...very safe....

The goggles arent going to stop your body being ripped to bits! Wear some overalls !

[iiredeye]

@Tommiclio Sorry poor comment sleeves around lathes are a very bad idea, I used to always wear them in the tool room, but when I was turning I used to roll them up...being dragged into the lathe by your overalls never did much for me.

[M1ST3RHYDE]

@Tommiclio

Theres more than 1 reason to skin a cat.

[ronBurgundy222]

wOW that was boring! Haha could resist that one. great video, lots of good tips

[beatnic50]

I'd have faced one end as square as i could get it and then turned the part around so the square end rested against the chuck. This adds rigidity to the setup. Also I'd use high speed steel tools to face and cut the place for your rollers as you don't use as need pressure to cut.

Loved the video, good work.

[sunnyboy67]

I like it

[bastion777]

I thought it was pretty interesting!...

Well, not really, but its great to have educational videos like this.
