Heavy Turning in the American Pacemaker
Вставка
- Опубліковано 27 вер 2024
- After getting the cross slide gib adjustments made I was ready to try some heavy turning tests in the American Pacemaker to see how well the machine will handle the cuts. This was also to test to check the headstock gears, quick change feed box and also the power feed mechanisms. I'll share the cuts I make when roughing in large gearbox shafts.

This is the kind of content I could watch for hours.
In the 40s or 50s maybe...LOL (Stirring the pot)
Last week Cutting Edge Engineering reminded me if your work and this week you remind me of them. Couldn't be happier.
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.
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!
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.
He has grown significantly, that's what happens when you do your job right?
Congratulations Mr. Adams for showing us your projects, you do them so well that you show us that respect for the profession of machinist
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!
Adam, this felt like one of the videos I orignally started watching your channel for when you were working at the machine shop.
Good to see some new heavy metal turning on your channel again. It's been a while. Nothing beats big chips!
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!
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.
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.
The American Pacemaker is one quality lathe. PERIOD !! They are the industry standard for the world. Nice cutting too.
Adam is an artist. This video is why I subscribe.
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.
Yay, back to classics Abom=heavy turning
Watching lathes make chips just never gets old--especially big ones!! Thank you for making these videos!! 👀👍💯‼🙏😎
Always a pleasure to watch your technical skill and passion for what you do. Thank you.
Got to love the OLD AmERICAN made tools
It's so good to see some serious chips like you did in your older videos. What an amazing machine you've got!
Damn those pacemaker machines are impressive!
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.
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.
That’s an impressive pile of chips. Glad to see the machine working up to your expectations!
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.
I vote to see a "giant" acme thread out of this thing. 😂
Hell ya! Old school Abom chips!
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.
I think your grandad is glowing with pride.
Some heavy turning. Exactly what brought me here all those years ago.
its all great but i like the pacemaker work the best. adam is always having fun! many thanks
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!!
Yaaay this is how I remember this channel
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.
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.
I think you should have a t-shirt made with you adjusting your 4 jaw Chuck saying tighten the highs and loosening the Lows .
What a Mad machinist… good job dude… beautiful
Adam, always enjoy your work... and it is not every day... even in a machine shop, you get to turn the big metal. I think that is why I enjoy watching the turning... even though I have done the same myself many times... it just is fun and fun to watch you do it too!!! Thanks!!!!
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.
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.
Good to know that the pacemaker is living up to its name. Nice machine. Thanks for the video Adam.
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
Amazing job. Always a pleasure to watch you wrk.
Love to see the return of some heavy metal removal on your channel, reminded me of the good old Abom content!
I wouldn't get too excited
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🇺🇸
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.
Was thinking the same thing.
Good deal Adam! That live center deserves a medal👍
We have centers a little bigger than that one at work and I have machined a shaft that weighed 26,000 lbs with it.
@@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
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.
Always enjoy your videos following you since I cannot remember. Thanks
I could say the same
why is watching chips pile up on a lathe so satisfying. lol. my big 150hp lathe makes massive chips i enjoy watching it hog some steel off. 20mm DOC they pile up fast!
I have to say that this video is more entertaining than the " look at the new toys and machines I got"...or the " my wife and I went on vacation to nowhere usa" when most of the nation can't buy anything new much less go on a vacation further that their Back yard. Hogging iron is more entertaining that what you have been showing lately...period!
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!
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.
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???
@@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.
@@forrestaddy9644 ah ok thanks. Fuck it would be alot simpler if there were 10 inches to a foot.
@@BramBiesiekierski And pi was exactly 3
Now that felt like some classic abom right there!!
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.
I like all machines but of the machines I've seen you use I think the shaper and the lathe are my favorites.
Thanks again Adam for this interesting content and great photography.
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. 😎
THANK YOU FOR ANOTHER FINE SATURDAY NNIGHT WELL SPENT
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. 😀👍
Heavy metal removal, what brought me to this channel 😮
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!
Man if I could do that I'd save some as souvenirs for the grandchildren too 😂
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.
@@aethelfreda I think he sharpened his own tooling.
Always amazes me, one piece of metal removing another. The power of the machine driving it through.
Awesome Adam thanks for the show
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 🤗
Wow, you got some new toys since last time I watched... Right on.
Very nice I had a blast thank you Adam
Love your heavy machining videos! That was the first one I watched years ago when you were at the other place
I remember when you did this on the Pacemaker at Motion. Seems like it wasn't even long ago. Wow.
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.
Thank you Abom! You never fail to entertain me, and teach me at the same time
Thanks Adam! 👍
Thanks for the great video!
The first video of yours that I ever watched was at your old employer's shop - it was a huge gear shaft... You did a lot of cool, practical, real-world projects then... Seems as tho you've gotten away from that. I do like how your videos are like a teaching clinic, educational.....
Thank you for sharing your talents!!! Always entertaining and inspiring!!! 🎉
Adam, I will say that I worked this formula both ways & came up with same rpm, I digress !!!
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.
Old's cool Abom content from back in the day 👍
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?
Really enjoyed it, love seeing the old iron working👍
Спасибо за видео, Адам.
А теперь - самое главное. Я долго искал на видео деревянный трап около станка, но не увидел. Мне кажется, что стоять на стружке во время работы плохо. Да и ходить по ней небезопасно. Поэтому мы во время работы стоим на деревянной решетке -трапе. Стружка проваливается сквозь нее и не мешает. Ширина решетки полметра, а длина равна длине направляющих станка.
Желаю безопасной и безаварийной работы.
The first lathe that I learned how to operate in high school was an American Pacemaker. It was a good solid machine.
had a blast watching.......cheers my friend, so great to see you expanding....
you are the man......
Making big chips like the old times! Nice video Adam!
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!!!
The GOAT is back!
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.
I'd say it has proved it is a machine tool that can meet your expectations Adam.
Nice to see the American Pacemaker running.
It is your surface footage. When you chips come off the part and immediately turn that blue gray color you are on the ragged edge of reliability. You want your chips to be bright blue or yellow blue. In 1045 that is about 450 SFM for roughing dry. Hardness also plays a factor. Your cuts at the lower surface footage sound really good.
Pretty sure I went deaf from listening to this vid but I enjoyed every minute of it!
Beautiful pictures also... 📸👌
No such thing as a failed test.
A successful test also reveals errors. That’s why you test 🤠
I worked in a machine shop back in the 1980’s and the goal was to make the machines sing.
Get it wrong and they scream. I understand you are testing out a new to you machine and making interesting UA-cam videos. :)
Well done that went well and was certainly interesting.
Eh, a failed test is possible. A lightning strike destroying the electrical system would cause a test failure without teaching anything new (for an extreme example).
@@PeregrineBF Well that would prove that that what ever you are testing isn’t lighting proof.🤠
I’m just saying if a test fails you s till get a result. It doesn’t mean the test itself was unsuccessful.
I do get what you are saying though.
@@DavoShed If a selution comes forward the test was not a failure.
@@chrismate2805
If a problem is identified the test is also not a failure. Unless it is struck by lightning (apparently)
I’m just saying a test that identifies problems is also successful. That’s why you are testing after all.
I like your attitude!
I believe you could do twice as much!
The tool damage in the vibrations that are occurring or from loading the machine so you’re right the more you do the more loads machine less vibration you’ll get depends on what you’re running.
Basically the machine has flex do you want to get past them or you don’t want to run in them types of loads .
Also when you’re making them big cuts your tool stay Sharp for a much longer time and you can do an incredible amount of work with The same tool.
You’re trying to take the heat away with the chips
If they’re blue you’re not into it enough.
Excellent video
Most people back when it chatters they should double or triple their cut that way the machines loaded or cut way nicer.
Whether I agree or not is unimportant. But I like to watch a lot of Cutting Edge Engineering Australia, and i see Kurt's chips are almost always flying blue.
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?
those cuts were making the ol' Pacemaker grunt... good test of the machine and your power supply setup.
That's some pretty tough narly steel too! Killer removal rates. Adam is the tripple red stripes black belt on the lathes.
At 30:33 right when you stopped, the last big chip stayed on top of the tool for several seconds.
Heavy work indeed. The Pacemaker is a capable unit!
Impressive.
NICE TO SEE THE SKILLED, HONING THEIR SKILLS. AS I A WELDER, RESPECT THE MACHINISTS SKILLS...OLD SCHOOL!
