Heavy Turning in the American Pacemaker

[@adambell2068]

This is the kind of content I could watch for hours.

[@larryrobinson7492]

In the 40s or 50s maybe...LOL (Stirring the pot)

[@castnetman]

This is the type video and content that got me to be a loyal viewer on the Abom channel early on. Thanks for posting it.

[@ilaril]

Last week Cutting Edge Engineering reminded me if your work and this week you remind me of them. Couldn't be happier.

[@td5disco965]

Hi Adam from the UK. It’s good to see you doing the stuff we’ve come to know and appreciate from your channel. I’ve been watching you for many years now. And while it’s good to see you progress into a new shop with lots of new equipment I really like the content you did to start with, seeing the older machines being worked by a man clearly very capable and knowledgeable. Please don’t forget your roots on this channel and those who love to see it.

[@NickyVEE89]

He has grown significantly, that's what happens when you do your job right?

[@TheObersalzburg]

Adam, I appreciate your presentations because you show the steps from beginning to end. Some channels show all the successful attempts, and try to make things look easy. You show us what you do, and the steps to get to that successful result. In other words, you show us how you solve problems. That is way more important than just showing a finished product. Keep up the good work!

[@carloseduardoabril1503]

Congratulations Mr. Adams for showing us your projects, you do them so well that you show us that respect for the profession of machinist

[@josephweaver7140]

Good to see some new heavy metal turning on your channel again. It's been a while. Nothing beats big chips!

[@dfnkt]

Adam, this felt like one of the videos I orignally started watching your channel for when you were working at the machine shop.

[@HonoluluTita]

I'm always amazed that you can take a rusty hunk of metal and cut into it with such precision with such an old tool and turn it into a beautiful part. Thank you for making these videos. You have such a wealth of knowledge!

[@Hey_Its_That_Guy]

You really put the old Pacemaker through its, well, paces. I'd be willing to bet that lathe helped win WWII. Nice to see that old iron handle the tests with ease. Thanks for sharing, Adam!

[@frfrpr]

Man that video was the bomb! Seemed like the metal was fighting back. Great filming. It's different seeing Adam actually challenged by his work.

[@Raskel8274]

I posted on your FB sometime last year about a 1948 american pacemaker I picked up. I am still learning (just a hobbyist ) and definitely learned from this video how such small adjustments can make. Still loving your videos after all the years since they helped me find a hobby which I enjoy. Folks I know give me a hard time for my first ever lathe being a 8k lb behemoth.

[@paulmcdonald9592]

Always a pleasure to watch your technical skill and passion for what you do. Thank you.

[@johncarder819]

Adam is an artist. This video is why I subscribe.

[@JohnBare747]

Fun for sure it's been a hell of a Chip Drought since you left Motion! Brings back memories of you hogging metal off those monster shafts, always fun to watch the Big Boy Chips fly. Thanks Adam.

[@davidanderson2915]

It's so good to see some serious chips like you did in your older videos. What an amazing machine you've got!

[@JerryHerb]

Been watching and enjoying your videos for years. Fun to see you turning a big piece of metal on an American Pacemaker again. I'm not a metal worker but I enjoy learning and appreciate your methodical approach to work and problem solving as you complete projects. Thanks for the video.

[@mdvener]

Just great watching you and you tools doing there thing. Being a retired electrician, something very special watching you and your machines doing what they do. You have a great talent n have been watching you for years. The sounds, the look of what you are turning I'm beginning to learn what to look n listen for. Can't thank you enough for everything you share.

[@andyoverall1951]

Feels like it has been a long time since we watched some heavy machining on this channel. I enjoyed it, thanks, Adam. I'm sure it takes a lot more to set up those deep cuts than what we saw on the video but the experience and skill still shone through.

[@sadaya69]

Great video. I sure did have fun watching this. It's great to see the pacemaker move some serious metal. Pumping out some chips in the new shop.

[@victoryfirst2878]

The American Pacemaker is one quality lathe. PERIOD !! They are the industry standard for the world. Nice cutting too.

[@JohnnyDee62]

Watching lathes make chips just never gets old--especially big ones!! Thank you for making these videos!! 👀👍💯‼🙏😎

[@stevebumstead9840]

CNC and manual. I love them both.

[@williammills5111]

That’s an impressive pile of chips. Glad to see the machine working up to your expectations!

[@jasonhull5712]

That was absolutely amazing. Man that is removing a tremendous amount of metal. And all that heat was going straight where it was supposed to, in the chip pan. Neat to watch man. Thanks Adam.

[@drstripe]

its all great but i like the pacemaker work the best. adam is always having fun! many thanks

[@Rangitatahunter]

Damn those pacemaker machines are impressive!

[@thefixerofbrokenstuff]

Good to see the ol gal making big pieces of steel into little pieces. It would be interesting to me to see the amp load when you're doing those honkin big cuts.

[@VanFlausch]

Nice to see the Paecemaker getting a good crank Adam^^

[@c0mputer]

I’d love to see the slow mo guys with their super macro extreme high speed camera and lens getting right up in there and seeing exactly what’s going on with a cut that big. Even testing out inserts and different hss shop made tooling.

[@steveshoemaker6347]

Great camera work....Some of the other channels are selling those chips in a clear plastic about 3' by 3' cube for a $100.00 a piece....Thanks to the man with the BIG SMILE 👍 Shoe🇺🇸

[@mfc4591]

Good to know that the pacemaker is living up to its name. Nice machine. Thanks for the video Adam.

[@acurarl9929]

Amazing job. Always a pleasure to watch you wrk.

[@bchant19]

It's great to see some nice heavy cuts again in the old pacemaker. It would be nice to see you doing some real jobs soon in the new shop like the old days @ motion.

[@joewhitney4097]

Wow, Your Pacemaker was really hoggin it off with that second insert with a beautiful cut. Thanks for sharing.

[@RobertGracie]

Precisely what I wanna see when I come home from a super long shift, some super heavy duty turning on the beast of an American Pacemaker!

[@caseyboutillier7510]

Hell ya! Old school Abom chips!

[@edsmetalworks8426]

Love to see the return of some heavy metal removal on your channel, reminded me of the good old Abom content!

[@ChrisMaj]

I wouldn't get too excited

[@niksechtniks]

Thanks again Adam for this interesting content and great photography.

[@dannyarendall5233]

Got to love the OLD AmERICAN made tools

[@joshclark44]

That. Was. Awesome!! 😂😂 man, that's what I've been missing after dealing with heavy schoolwork the past several weeks. Some good old fashioned Abom79 content! Glad you're back buddy! I would totally LOVE to see you machine up some massive abom sized gearbox shafts with those big machines!! That would be freaking amazing and I'm sure everyone who follows you would agree!

[@mikeaustin9810]

I think you should have a t-shirt made with you adjusting your 4 jaw Chuck saying tighten the highs and loosening the Lows .

[@kittty2005]

I like all machines but of the machines I've seen you use I think the shaper and the lathe are my favorites.

[@forrestaddy9644]

Shaft for a vertical gear reducer? I suspect a medium carbon low alloy steel maybe rC 20. 500 FPM seems a bit fast. When you mentioned the material, I thought 350 FPM but I've been retired for too many years. From the front only viewing angle I can't see the tool overhang from the tool post. The squeal suggests you have about 1 1/2 shank heights overhang. I suggest you shorten it to one maybe less. Also maybe shim the toolholder bottom solid to the compound top. Anything to reduce elasticity. Never used those edge-on inserts. They were just coming on the market when I retired. I like the deeper edge support.

[@BramBiesiekierski]

What do you make of his calculations at 5:00? He uses 3.82 as the multiplier. I'm guessing that should have been 3.14???

[@forrestaddy9644]

@@BramBiesiekierski Kaufmann futher down addressed that. 3.83 is 1 ft in inches (12) divided by pi. You could use 4. Makes mental calculation simpler and you're only looking for a rough number to optimize.

I vote to see a "giant" acme thread out of this thing. 😂

[@johnstrauch2112]

Now this sort of video is definitely educational. I like all of your vids but really like this one. Stateing the speeds, feeds and depth of cut is really good. As well as the reason for them. Failure is one of our best teachers! Oh and what is that metal since that is another important bit of info?

[@ZAMsChannel]

I only have a small hobby lathe, but I learn a lot from you. Thanks a lot. And greetings from Germany, where the Multifix comes from, I also use them. 😎

[@omw-bavaria]

Very nice Adam 😊 looking forward seeing some gearboxshafts made in your nice shop 😎👍 as a long time viewer I missed that, but it takes time to set up a shop like this, so I waited patient for this, I hope I get to see some of the old school Abom mixed with some new school Abom working on them nice parts and machines soon ☺️ Great Adam, I learned a lot from your videos, lets see what comes next 🤗

[@kevinkatz7027]

Wow, you got some new toys since last time I watched... Right on.

[@jtrent3960]

Good deal Adam! That live center deserves a medal👍

[@TheJohndeere466]

We have centers a little bigger than that one at work and I have machined a shaft that weighed 26,000 lbs with it.

[@jtrent3960]

@@TheJohndeere466 good deal, I was thinking about the center holding down against the tool pressure. I don't have much experience with parts more than maybe 200lbs

I remember when you did this on the Pacemaker at Motion. Seems like it wasn't even long ago. Wow.

[@aethelfreda]

I watched the Swedish gearbox shaft videos last night. That was beautiful to behold and mostly done on the Pacemaker at Motion. I couldn't believe that it was 5 years ago.

[@TheJohndeere466]

I used to run an american like that except it had a hydraulic duplicater on it. I roughed 8" 4140 crane shafts. I would take .750" total at .032" feed with kennametal tnmg 542 KC850 inserts.

[@94XJ]

Now that felt like some classic abom right there!!

[@nelcann7333]

Always great to see the manual lathe at work! Awesome machine👍🙏

[@paulmace7910]

It would be interesting to see what the hp (amps) on the lathe is while doing those heavy cuts. I would think there is some hp not being used that would be fun to try and take advantage of with different tools or feeds/speeds.

[@Paul-FrancisB]

Yay, back to classics Abom=heavy turning

[@ypaulbrown]

had a blast watching.......cheers my friend, so great to see you expanding.... you are the man......

[@glych002]

Thanks for the great video!

[@gottfriedschuss5999]

Adam, Another great video. I, too, would like to have seen an amp meter on the motor, just so we could have an idea of the percent of full load when you are taking these big cuts. Machinery's Handbook, et. al., have sections talking about the HP required to remove metal with d depth of cut, s step over, and r revolutions per minute in a given material. It would be interesting to compare theory and actual, real world observations. Another aspect of a good insert that is not often talked about, but is important on big shafts and such, is that a good insert contributes to removing heat from the parent material. The lathe operator wants the chips to be scalding hot, taking the heat of "tearing the steel asunder" away from the parent material. This heat isn't just friction. There is heat just from ripping the steel apart at the molecular level. Carrying that heat away with good insert design is a "cousin" of ablative heat removal, for example, the heat shield on a space capsule.

[@andyd1006]

Love watching big machining jobs.

[@toddhaas6675]

Really enjoyed watching this. I was able to learn a lot about how adjusting the Feed & Speed affects the cut. I have a small Tormach 8L lathe and cannot make cuts like this, but this demonstration will still help me in my learning process. Thank you!!!

[@tonyshupe2334]

The first lathe that I learned how to operate in high school was an American Pacemaker. It was a good solid machine.

[@3073Sean]

Adam, not sure if you’re going to read this, but I am sure you’re aware that EBay has tens of thousands of counterfeit tooling. I did my very best on preventing that once and I purchased a Mitutoyo 6” caliper, and one day I took the battery cover off and thought it looked different. I compared it to many of my other Mitutoyo calipers and found out it was a Chinese knock off. I have had this a few times on different items. They go to the ends of the earth to generate counterfeit items. Not saying your insert was counterfeit, but it could have been.

[@stephengile530]

Was thinking the same thing.

[@dennistennyson8856]

That's some wonderful therapy Adam

[@Slikx666]

Them's big chips! I watched one of the This Old Tony's videos yesterday feat. ABomb. He's lost a lot of weight, nice one Adam. 😀👍

[@jimmyboles3409]

Really enjoyed it, love seeing the old iron working👍

[@michaelcothran4064]

Adam, I will say that I worked this formula both ways & came up with same rpm, I digress !!!

[@shaneroper5470]

I know someone who's grandfather used to be a machinist from back in the day, and he had a few examples of chips... or coils of metal he peeled off that were a half inch to 5/8 inch wide by 8 to 10 thou thick and 8 feet long. So many variables to pull that off, but he knew his stuff no doubt!

[@joshclark44]

Man if I could do that I'd save some as souvenirs for the grandchildren too 😂

[@aethelfreda]

I'll bet his tools didn't have moulded in chip breakers. None of the ones I used in the late 70s or early 80s had them. When I got ones with chip breakers it was a whole other business.

[@shaneroper5470]

@@aethelfreda I think he sharpened his own tooling.

[@patrickcolahan7499]

Adam, your tips are not failing, you are learning how to run cutting tools. Regardless of the code, not all manufacturers are the same and their product perform differently. I love this type of video with trial and error. Just like we all experience in our own home shops. Keep it up, this is the Adam we know and respect. Thanks for sharing. Question, does the performance of an insert vary depending on the lathe?

[@gordonno11]

That's a hard steel......need to run in the 250 -300 fpm speed range......500 fpm for mild steel. Love your work, keep it up!..... 37 years, as a manual machinist..... another 6 to go!!

[@maggs131]

I love the shifter design on that lathe. 24 speed with a hi mid and lo range 🤘😎 truckin

[@machiningmule5525]

Some inserts do not like mist cooling it can cause thermal shock and reduce toollife either run it dry which i don't recommend when turning or use floodcoolant

[@ellieprice363]

The shock happens when you hit a hot insert with cold water. If the insert starts cool and stays cool it works fine. Proof, a .250 cut with no problems.

[@boostbuggy217]

That's some pretty tough narly steel too! Killer removal rates. Adam is the tripple red stripes black belt on the lathes.

[@StevenHess]

I'd say it has proved it is a machine tool that can meet your expectations Adam.

[@TeachMeTheGuitar]

Fun to see that old part again. High speed footage of those chips being made would be neat. Maybe the slomo guys would be into a collab.

[@tobiasbostwick9002]

Great show, enjoyed it, Adam. Thanks.

[@MrMattydavee]

I have both of those inserts on hand right now. I got straight from my company rep and their different color then yours. I bet there counter fit

I’m wondering if that shaft has a heat treat thus making a surface hardness.
