[@bigbadbugga]

Thanks guys, I've learnt more about insert tooling in the first 14 minutes of this video than I learnt from 4 years of watching youtube machining videos.

[@fredrosse]

Me too, and been machining stuff since 1960

[@meocats]

give Paul another episode on drills in the lathe, all types of drills. he's the man!

[@wheelman007]

Just wanted to say thanks. I must have watched this video 20+ times for a reference.

[@Steve_Just_Steve]

This maybe my favorite video you've ever done. Paul is such a nice guy for helping you share this with us. Would have been nice to get a better look at the inserts themselves like maybe some closeup shots so we could see what the chipbreakers looked like but great post John, really enjoyed it and can't wait for part 2.

[@nyccnc]

Steve - thanks, and agree - we'll make a better point to do that when we film next time.

[@Pow3llMorgan]

Paul is an excellent teacher and John, you acted the virtuous student very well, namely with the intermittent chip sweeps :P But seriously, Paul is like machining god.

[@antonmursid3505]

Antonmursid🙏🙏🙏🙏🙏🇮🇩🇮🇩🇮🇩🇮🇩🇮🇩✌👌

[@michaelawuku1241]

I really like how the old boy response to the questions. He don't rush to answer a question. I hope he works the same way

[@jakegiubbini]

Thanks guys. I saved this video and refer back to it frequently at work. I shared this with my old machine school instructor and he now shares it with his classes.

[@bradjunes1610]

I grew up (55 years in machining) with "Stelite" tools. "Heat the part up till it's red and start cutting" the old timers taught me back in 60's. Weld it hot and start cutting. Finished with all types of tools after straighten of boat shafts etc. Wish I had cameras back in the day before carbide you would see lathes of the 1940s doing awesome work and even to this day.

[@jorgefernandez184]

As a machining student, thank you! These long videos with thoroughly explained details are incredibly helpful and educative. I definitely commit the typical beginner mistake of taking too light of a cut, haha. It was shocking for me to see cuts that are like 4 times deeper than what I usually limit myself to. Anyways, thanks once again John and Paul, excellent content. Cheers from Spain!

[@michaele1201]

Hey John, Awesome !! there is a lot of wisdom introduced to the viewers in this video. Paul 's experience and your "curiosity" and ability to ask intelligent questions is a great combination. Well done!!

[@nyccnc]

Thanks!

[@larrysperling8801]

one of the best tutorials i have seen on carbide tooling. now we need a similar one geared toward the lighter home shop lathes. great job looking forward to the next installment

[@billdoodson4232]

I'm not a machinest, but have used machine tools and been responsible for purchase of tooling for them as part of my job as the Chief Engineer for a number of maintenance depts, mainly in the food and drink industries. I did quite a bit of research about 30 years ago on what might be the best all round tools and decided on the button and triangle inserts as being the ones that would cover most uses and be cost effective in an envirionment were we could be cutting 304, 316L and hot rolled mild steel within the same day. I still use these same inserts in my home workshop today and have to say that Sandvik have never let me down. Its nice to watch a video with a couple of real machinests, confirm that the choices I made as a total non expert all those years ago, were pretty well the correct ones.

[@BradleyWilloughby]

There’s something so satisfying about watching a manual machine make chips compared to a CNC.

[@floridasaltlife]

Paul is the very best of dudes !! I love this guys disposition, The way he shares and teaches at the same time is incredible. My lathe is smaller at a 12x36 2hp and sized right for my needs in scale model engine building but the concepts are scalable and the same. I really learned here. Million thanks to you.

[@jimsvideos7201]

Good on everyone who had a hand in making this! If you need SD cards I bought a heap for a vacation that didn't happen, you're welcome to a couple of them.

[@ZPositive]

Wow, so much learned in just one video. Absolutely top notch content. The very reason KZbin was created right here.

[@nyccnc]

Thanks!

[@cffellows]

Started out thinking OMG, and hour and half, this has got to be boring. Turns out, I watched the whole thing, and completely lost track of time. Great Video! I've long been familiar with Mr. DeBolt from his model engines./

[@nyccnc]

AWESOME!

[@bschurg3588]

Oq

[@mrechbreger]

I like such videos, it shows people who really like what they do and try to get into the details. On the other side I know people who only do what you tell them, and when they're getting older ... they're getting lost because they have no one guiding them anymore.

[@elcuhhh8761]

These types of machining videos are my favorite

[@outsidescrewball]

Long video and thought NO WAY will I watch....DAMN...couldn't shut it off...... THANKS.....so much information...awesome

[@r.j.sworkshop7883]

Thank you John and Paul. I just got done watching this for the first time. Next time will be with a notepad. Your timing is excellent for me, I am expecting my new to me 16x40 in a few weeks and I have had my nose in every catalog that I could find reading up on insert tooling. Also, I noticed a round insert tool holder in the box of parts included with the machine, and I thought that it would be a novel little tool to have, now I am certainly going to take a much closer look at it. Great work and as said by others, I couldn't believe that 90 minutes went by so fast!! R.J.

[@shiro-r4m]

I love it when you visit DeBolt

[@DavidHerscher]

This video is freaking legendary. I just learned so much. I'll be watching this at least 50 or 60 more times to soak in all the info.

[@racekrasser7869]

I would love to work with and learn from this guy. We need more people like him in this world.

[@themotofix5705]

I hope to be a fraction as knowledgeable as this master machinist, one day.

[@bostondan77]

Editing in your videos is top notch. Thank you.

[@JShel14]

So much knowledge dropped in this video. Thank you so much for sharing!

[@glenkelley6048]

THANKS SO MUCH GUYS, for knowing what you are doing. Machine tools make our world go around, and YOUR KNOWLEDGE and SKILLS make that possible. 'God Bless You BOTH!

[@ypaulbrown]

Very informative... didn't think I would make it all the way through, but after a few minutes I knew it would be great. I ran the same model lathe for over a year...made many unique parts. Well done Paul and John.....cheers, PB

[@thomaslamora1679]

This video wasn't what i expected... but it is amazing the "walk around" knowledge that some people have.

[@BeaterJeep]

I started watching “1018” and a portal to hades opened in my kitchen…… lol seriously, great video!! Thank you.

[@FrustratedBaboon]

Paul has so much knowledge about lates. Very Impressive.

[@Tf9500]

That hour and a half went quick, great video with lots of hands on knowledge. Adding to my favorites, Thanks for all you do👍

[@aeromech8563]

Guys I have watched hour after hour of you cutting steel n feeding n chipping Fkn awesome man I'm setting a private shop up when I'm back home in Australia I have learned so much tech shit from you thank you so much for your great videos and interesting tips just letting you know how great it is to watch engineers at work. Cheers Phil. Ps I'm an aerospace engineer and can't get enough of this content 🛠😎🇦🇺

[@jaypierson5955]

1 word about the educational content in this video: Goldmine!

[@nyccnc]

Thanks Jay!

[@anthonyquarrell9068]

What a guy! He'd make a good master for a lucky apprentice.

[@Dr_Xyzt]

This is a cool video. The clink of metal chips is satisfying in a way that's similar to bullet casings, but not as much work.

[@billherreid9661]

Thank you! I need to watch this about 5 more times.

[@samuelseager6785]

You would think that 1 1/2 hours would be too boring to get through, but I'm with you. This is a must re-watch.

[@MrRctintin]

Great video, thankyou. I’d love to spend a few months working with that fella, he sure knows his stuff!!

[@johndebrular979]

To really appreciate the ability of this shop and Paul you should have known his dad. A class act. Located near Zanesville, Ohio.

[@FredMiller]

Great stuff! I am going to have to watch this a THIRD time to really absorb it. Thanks Paul and John for taking the time to educate us. I am really looking forward to the next segments. All the best.... Fred Ontario, NY

[@sanforce]

Planning on turning steel for the first time today ... great timing on the video!! Thanks.

[@louiskeen8475]

Thank you gentlemen for this explanatory video!

[@nyccnc]

You're welcome!

[@rickcperry]

Watched every minute!!! He don't need no stinkin cutting oil.... BAD A$$, One of the best vids out here on the Tube!

[@vliberal]

Awsome, i hope you find time to continue the comparison video, i am super excited to see the stainless.

[@ranchis9044]

love when you said .. now thats a great Abom chip

[@jackjordan7691]

This is so informative, thank you. Fun to watch.

[@damionparson247]

Super video! Answered a lot of my questions that I had about inserts.

[@melchvanleeuwen2166]

wow what an amazing video! thanks guys i took alot from this.

[@martinda7446]

This was magnificent.... I just want to add another 20 alloys... And... I'll check the playlist...

[@itsmebernie]

This series of your videos is some of my favorite content of yours! I play them over and over to try to make it all part if my thinking. Thank you!!!

[@DIRTYTHUNDERCUSTOMS]

I really dig these kinds of videos. U rock

[@nyccnc]

Thanks!

[@sandeepnepal2064]

This channel is underrated AF

[@xmaswitguns]

These men are a wealth of knowledge!

[@drienkm]

Thanks so much for doing this. I'm learning how much I didn't know about turning!

[@Hunter_S-fr4ns]

This is ACE!!!… just got yourself a new subscriber 🇬🇧

[@xtiz]

This guy is awesome, like a father. Love it 😊

[@troutfitter547]

I wish this guy was my next door neighbor.

[@904justify]

These guys have done awsome job explaining this stuff

[@hilltopmachineworks2131]

Wealth of knowledge here. Thanks Paul and John.

[@johnnym1320]

awesome video! Paul is a wealth of knowledge!

[@someoneelse7629]

Really nice to see that you both liked Sanvik inserts, when I did my last machine class, it was all Sandvik inserts, the perk of living in Sweden before international shopping and sorting for cheapest was the norm. But I talked to guy working in production recently, they still use all Sandvik, it is still cheaper in the long run since they last much longer then any thing else they have tested

[@michaelhatch6283]

I am coming to this video late but so much knowledge shared. Thank you both so much for this content. Awesome video.

[@jimmilne19]

Really, really helpful video. Super useful. Thankful here for the fine instruction. And, Paul, totally impressed with your knowledge and clear explanations. Thank you!

[@antshark]

Great video! Paul is so knowledgeable! Thank you John for creating this content.

[@tannerhoward5974]

Awesome! Showing people you can push a lathe instead of talking forever like many do.

[@ronaldwhite5887]

Well done, thanks I learned from your video that some cases you may not to break the chip completely if it is flowing out of the way into the chip pan. I used to grind a small radius on the top side just behind the cutting edge to allow the chip to break off into small pieces to avoid the “ birds nest”.

[@Musicalbullet]

Awesome video! A wealth of knowledge!

[@alextatkin1026]

This channel should have more subs.

[@davidl9410]

1 hour 30 minute video... yes!!

[@CapeCodCNC]

That was an incredible video! Make more like this!

[@nyccnc]

Copy!

[@tmcweld]

Been waiting for this video since the teaser!

[@nyccnc]

:)

[@tsstsstsstsstsstss]

I didn't know Colin Mochrie did machining! Awesome video, John. Thanks!

[@billdlv]

Great info, just like the aluminum video a while back. I was able to follow along but it would be helpful to have on screen the parameters for each cut like rpm / feed rate / DOC or at least show when one is changed. I'm going to have to get a round insert toolholder.

[@nyccnc]

TBH, I tried to do that and just couldn't keep up. Not a great excuse, but it's something I have never been able to do well when visiting someone else's copy to film/learn

[@greglaroche1753]

What a great video. Thanks!

[@TheWidgetWorks]

So far so good, I should send you some C275 or some inconel 625 so you can show what a massive difference there is in materials.

[@nyccnc]

I'm great at machining Inconel. In CAM.

[@Andrewlang90]

@@nyccnc Late to the party, but Incnonnel surface finishes beautifully, but like EN30B, it’s incredibly abusive on inserts and tooling in general

[@bcdesignco8013]

Paul is such a badass guy! Great content!

[@nyccnc]

Thanks!

[@shadowdog500]

Great info!! I'd love to see someone do a video like this for those of us with older lathes with less that 1HP, like my old MSC 11x36 belt drive lathe. Thanks, Chris

[@nyccnc]

We're going to take what we've learned and apply it to our Tormach lathe!

[@shadowdog500]

Thanks! I can't wait to see the video. Chris

[@dorsetengineering]

Hss tooling on vintage stuff in my experience...

[@glennedward2201]

Interesting all the steels I work with. At times it cuts like butter and other times I think I have different material than what’s labeled. One of the issues I’ve ran into is the use of hot knives to cut these larger end drops off can often harden the material making it hard on one end, both, or inconsistent overall which can make machining on a lathe a pain. I have found on the vertical mill I can cut it in any mix of the above without much issue. It’s good to hear what others are doing it only expands the workability.

[@SV_Sangha]

Wow, what a wonderful video!!

[@PurityVendetta]

That Mr DeBolt, one smart guy. Fascinating video, although I work everyday on one off type jobs I learned a lot. Lots of subjects to think about. I'm going to have to watch this a few times to take it all in. One thing that drives me nuts is that the WW2 EN system of steel types is still in use here in the UK. I have to cross reference all the time.

[@PFSDUDEK]

Great to have two really knowledgeable guys together.. I remember NYC CNC starting out... But i do prefer manuel lathes and Mills. because CNC are not human machinists.. I am.. But great video guys thank you...But remember the average guy ! the mere mortals..Ha..

[@denniss6317]

really good Video, i´m learning as a cutting mechanic here in Germany, dont know if its called like this in english. And this helped me a lot to understand it again better than before :D Thanks for that.

[@LittleRestraint]

Wow, I learnt so much from this video, thanks guys!

[@richbuege6491]

In my small machines, I don't use carbide, but HSS. Most of the steels I use are tool steels, with some exception. 1045 , hydraulic cylinder rods, of course hardened, chromed, but I got them for cheap. Watch the speeds, don't let it get too high, keep the feed reasonable, use a junk tool to get rid of the chrome and don't be trying to take .002 or .003 for a finish cut. Leave .010 or more and it works better.

[@davecreer9]

That gut knows his stuff learnt a lot thanks

[@adamsblanchard836]

hey, y'all stopped, collaberated, and i listened.....thanx V.I.

[@rlockwood2]

negative tooling can have positive, neutral, or negative rake.. positive tooling can have positive or neutral rake. Seemed like there was some confusion about that right about the start when this was being discussed. The two are related, but also not.

[@Sketch1994]

An insert can be neutral or positive depending on the clearance angle. The rake angle can be positive neutral or negative independently of that, but it is compounded by the toolholder angle which can also be positive neutral or negative(can't use a positive angle holder with a negative insert though). It's rake versus clearance.

[@doug3458]

Great video, highly informative. At 1.14.20, the cranked tool with the round insert is a right hand tool, not left hand as stated. The hand of a tool is determined by looking at it from the cutting(insert) end. Lets say you required a raised feature in the middle of the part using cranked tooling, you would cut the right hand edge of the feature from the end nearest the tail stock with a right hand tool and the left hand side of the feature from the end nearest the chuck using a left hand tool.

[@kevingerrits6979]

My journeyman sucks. I wish I had someone like this training me.

[@mustbejoking]

Awesome just pointed out how much i dont know explained alot of issues that i encounter...thanks paul you are good at what you do

[@sunppaa]

Good stuff! Looks like the 4140 moved in the jaws during cutting though!

[@maizecarter9713]

This is awsome info 👌🏼 thnks guys

[@wernerberry7800]

Super great video John! Love to the old Guys!

[@bingosunnoon9341]

Ten minutes of content packed into an hour and a half

[@kennygee6627]

Wow, PACKED with great info. Learned a lot on this one. Thank you!

[@eliascastillo1641]

Great video. Problem I’ve had taking Huge cuts like that is the material might actually start pushing back into the chuck if you can’t butt it up against the jaws.

[@ext700]

Great content. I think Paul needs his own channel.

[@jnelson4765]

Talking about the right insert for the lathe, I've been using Sandvik TNMG 222 inserts with my little 7 x 14, and they're some of the only inserts I've found that do a proper chipbreaking on cuts as shallow as that poor little thing tan take. Not everybody has a 20 HP turning center, and with limited horsepower or rigidity, finding inserts that don't beat the crap out of the machine is hard sometimes...

[@shadowdog500]

Thanks for the tip on the insert for smaller lathes. Chris

[@nyccnc]

AWESOME! Yea, I can't believe how that "T" style performed!

[@shadowdog500]

Jim, Can you post a video of that insert breaking chips on your mini lathe. I'm sure a lot of people with those smaller lathes would like to see that. Thanks, Chris

[@jeffcrossler3186]

you should tell people about a book called engineering black book it has all the info your talking about ...i love this vid keep up the great work

[@jeremydoblinger3609]

This is gold!! Really is

[@robertkutz]

Very informative video.
