Compound Rebuild Begins for American Pacemaker Lathe
Вставка
- Опубліковано 30 вер 2024
- I'm getting back on the American Pacemaker project of repairing the compound slide. In this video we'll get the surface rust cleaned off the two main components then using a Biax power scraper apply a cross hatch scrape pattern to the bottom side of the slide ways. This will help provide better lubrication when the two parts are mated together.

Taking nothing away from your new machines and technology but to me, the Pacemaker is the star of the show. The old Pacemaker at Motion and the big shaft turning was the reason I started watching you.
This comment section is a bunch of babies lately. Why do you guys feel the need to be toxic? I just don’t get it. Yes fellas, changes happen. Thats what happens when you work.
Waaaa, the music-
Waaaa, CNC-
Waaa, sponsors!
Wheres my trophy? I watched the video too.
Nice video Adam.
I agree. Some people can't accept change, although it's part of growth.
@@haenmaen So people shouldn't have an opinion?
@@colinfahidi9983 where do I say that?
You know, I follow almost 160 folks on youtube of all different interest, but I think I enjoy your videos most of all. Maybe because Im an old retired steelworker myself, or maybe because your videos are just so true and interesting to me. I would have loved to have trained (worked) under you. Thanks for all the great videos....from one steelworker to another! 😃
Hi, 38 years in the trade. I love these video concepts.
I love seeing these videos of old machinery being revitalized. I remember talking with a machine scraper 40 years ago, he told me scraping cast iron is hard, it is easier if you are comfortable while doing it. That stated, I have done a bit and I think it is like welding. If you are in a comfortable position while doing it the results will be better..jmho.
I’m gonna upvote just to spite all the whiners. You know you don’t have to watch this, right?
Bc of this comment… wanted to see what got you all butt hurt and besides a few minor opinion differences not much “whining” going on. You shouldn’t read comments if this gets you hot and bothered man
Can you explain just what you believe the objective is by doing this operation?
It's great to see that wonderful machine getting the loving care it needs. The video work is also excellent and provided optimal viewing of this work. Without wishing to complain at all, I don't think the music adds to the video, but I know opinions vary on this. Thanks in any case for another wonderful video.
If you setup with the item at 45° to the table you have a reference to go by..... Looks good and will hold oil as desired!
Interesting the scraping is 0.002" deep. I would have thought it was much shallower.
Finally some real machinery again!
Thanx Adam for the good instructional videos. Not too much talking, great music, inspirational stuff for those who need a little help in this field. 😃
Im just curious but shouldnt u avoid honing the stones over the workpiece to keep anything u knock off from landing on the workpiece which could then end up under the stone gouging the metal? Probly not important here but seems like something youd want to just make a habit of not doing
Makes sense.
I like the regular intro better
Just doing maintenance and light overhauls on my equipment, I find an ultrasonic cleaner to be very useful for deep cleaning the parts before oiling and reassembly. Especially on any "touched" parts like handles and levers. Really gets them to the next level. Also gets the microscopic particles from chips and grinding out of the parts that normal cleaning doesn't remove.
I remember as an apprentice, hand scaping the ways and then hand spotting them. I was taught to create a crescent shape spot in a cross pattern, to retain oil. After many hours of practice l got pretty good at it, so much so that l felt it was a sham that it wouldn't be seen. Never used the electric scraper.
I can hardly wait to see that big boy making chips
If you want to move away from the Sharpie marks, put your piece at a 45° to your bench. If the workpiece is square or rectangle, you can visually reference off the edge of your bench to make nice estimated 45° angle passes.
Glad to see the pacemaker getting some love. I am still looking forward to some big heavy cuts on it. 🙂
Thank you for another nice video.
this is the content i love to see.
quick clean up to put her to work!
This might be a silly question. But here goes. So the scraper makes micro groves for a reason, so you do it. But so does a fly cutter, or a face mill. I know this compound wasn't freshly made, but on a brand new part, would the machine marks serve the same purpose as a scraping operation?
machining marks are much much shallower and much smaller than scraping marks, so they can't hold nearly as much oil, and i would guess (this part is total speculation and i could be completely wrong so take it for what it is) the size and depth of scraping marks might allow the surface tension/film strength of the oil to come into play to help maintain the layer of oil between parts
search for "Abbott curve". it's about howmany mountains and how many valleys you have, which gives you the bearing surface. a scraped surface has a much better profile, because of little mountains to scratch the opposite part and shallow but wide valleys which carry the oil. also if you look from top down on a flycutter surface, the edges, where the cutter almost cuts tangentially, will have like only valleys, opposite to the center. the start and end of the cut can also be a problem due to uneven load on the tool.
Looks excellent Adam. You're clearly doing an excellent job. I'm just wondering why you used a power scraper and not the power flaker ? It seems to have done a good and less aggressive job but when I was building machines we used a flaker for oil grooves regularly. It definitely does the job for a smooth machine axis though. 👍
Nice work Adam it's looking good. Nothing wrong with the witness lines especially if you don't use the scraper regularly. It's kinda like shooting a gun, yeah you can hit the target but your groupings are more consistent when you practice. I found that my rows are more straight when I lock my elbow against my side and dip side to side from the hips as opposed to twisting at the waist. Keep up the good work.
It’s amazing to think that that old beast could still be making chips in ANOTHER 80 years.
That is a tricky job Adam.
Well done, it looks great and it makes sense to have it on the upper surface only.
Keep up the good work.
I'm looking forward to my this after refurbishing my old Logan lathe. I'm a little nervous so I'll have to practice a bit on some sheet metal I have laying around the shop. Thanks for sharing this.
Attention to detail and not overdoing it ! wonderful. I hope this will be a great piece of equipment that will serve you well.
That was fast and will hold oil. Good job.
Adam, really like the intro. I enjoy the behind the scenes stuff as much as the machining. Most folks don't appreciate the amount of work needed to maintain the 'old iron".
Absolutely LOVE the intro roll on this, and the music score fits PERFECTLY!
A little blue would help show what you are knocking down.
Can that center post be removed? The entire surface looks like it needs to be milled a few thou. Clean your stones.
have you considered getting a vapor blasting cabinet? seems like it would be an excellent addition to your shop for cleaning parts
The music changed. Prepare for the outage! Nice choice on the new tune.
I for one hated the old song. Not because there was anything wrong with the music itself. But because it started panned to the left and I tended to think that my headphones were starting to break.
@@Gameboygenius hey, this is a reasonable cause for dislike, and you've managed to retain your outrage. Go to the head of the class! And so you other people, take notice! This is how you react to things you may or may not like, rather than shouting everyone else down or raising a mob to cancel them. Respect+
Bonsoir de France ville de Grenoble
Vous êtes super Adam toujours dans le calme la mécanique vous parle même si vous êtes seul dans vôtre atelier
la musique est inutile dans la précision c'est mieux d'entendre le bruit du grattoir
What an amazingly thorough job man you do very good work.
Your channel is always fun to watch. One of the first videos I watched was you turning some really large item on the lathe. Listening to you talk through your projects, it’s obvious you have a passion and skill. And often, you are also like Bob Ross. Your channel is very relaxing. Thank you for doing what you do.
Adam, if someone was to per say Link a few of your videos into their course content for instructional purposes how would you feel about it?
Adam, you are not only a high-tech CNC machinist but also an artisan, able to lay down a really nice scraping pattern. The way you flattened that plate with a mill file and a pair of precision stones was a joy to watch.
Great footage, there is always something to learn from your videos but, *Adam* please can you tell me what grit size your precision stones have, or what grit size is useful ?
Special Greetings from Austria 🇦🇹
When I first saw the thumbnail, I thought you put a Guilloché pattern on the surface like the do on the inside plates of a watch.
It would make an interesting video if perhaps Adam (or even someone else) would do a demonstration of different surface oil or lube retention methods .Compare grooving, scraping ,or flaking on similarly sized surfaces and amount of cycles from wear movement and whether or not both wear surfaces need treatment and compare them to a control untreated surfaces, just an idea.
For a total clean. I found to clean old cast iron inside and out is to do a cascade soap boil out. I use half a 50 gal drum with 2" ID pipes laid in the bottom to circulate heat around the part to do the boil out in. Works very well. It draws all the old grease and emulsified oils out of the cast irons crystal substrate. Than after a torching to draw out the last of the water. I than put the part while it's still hot in 3n1 oil to soak over night.👍👍👍👍👍Even use a 5 gal industrial sonic cleaner for all the other parts using cascade.
Im curious if anyone uses comet? It doesnt just remove oils but chemically transforms them
@@GonzoDonzo I wouldn't use it on machined or polished surfaces cause of the abrasive in it, But to clean outside of shell castings would be fine.
I remember when you visited that guy to practice this. Nice to see you applying the knowledge. Looks great! Also looks like a lot of fun.
Looking great man , your scraping / flaking has improved substantially in the last few years . I really need to get to practicing my own. Looks fantastic thanks for sharing your journey up to this point 👍
Looking really good. Will be nice to have the Pacemaker back up and running. Thanks very much for sharing.
I would love a coffee table with the scrapping pattern. There are videos of these Japanese scrapers that do beautiful work it’s like art, your ain’t so bad either Abom
Hi Abom,79, could you use your CNC milling machine to do the hatch pattern ?
You didn't really go "The other way"; you just started from where you ended and just went backwards. You should have just turned the piece 180 degrees and you would have a nice cross hatch.
YOUR DOING GREAT SCRAPING, ( I THINK ) PATTERN LOOKS GREAT
I seen you were looking for a oil gun Keith Rucker has one you should contact him.
Awesome I've been hoping you'd get back to doing American Pacemaker content, as I've been really looking forward to seeing you get it rebuilt bc its such a beautiful machine!! 👍👍
Have you decided whether or not you're going to repaint it or not? I hope so bc that gray didn't do the lathe justice.
If you do paint it my vote is for a pastel Green color just bc the lathe has Art Deco design cues and bc almost everything designed during the Art Deco movement was painted in pastel colors.
Nice work on the flaking. Thanks for the video.
Do you reference one side of the compound to the other so both sides form a single plane?
Really like the new soundtrack. The old one was getting a bit weary.
Thinking out of the box on this. Way out of the box that is... Could a person not create an attachment to mount that borax scraper onto your power shaper. I know it would be easier said then done to make the mount but I feel like the stroke of the shaper would help in creating stait scrape patterns
"Easier said than done" and "More trouble than it's worth" I think would be the key
Finally some elbow grease. Great job Adam.
Wish china would make a cheap one time use version of the biax for like 60$ hand scraping is to much work for the one machine I need to work on and it’s to much of an investment for the biax to repair my 645 wells index mill actually debating scraping the head on it and building my own for a few reasons
Don’t get me wrong if I got into it and enjoyed doing the scrapping work I’d buy the biax but for what I need from one it’s just not worth it literally have 700$ in my mill hard to justify double for a tool to fix it
China can't even make a hacksaw blade that doesn't shatter .Hardening ,they understand .Tempering is just a mood swing to them with their rubbish.
@@mauricelevy9027 don’t need it to last just need it to half ass work
They do! its a harbor freight sawzall. you open up the mechanism in the front and move the eccentric pin closer to the center of the rotating hub to create a shorter stroke. then make a custom "blade" with a piece of a carbide brazed to it. Works fine for small/one off parts.
@CaLem made one on his channel from I believe a reciprocating saw
Do you know what material the gib is made of?
I like the pattern. Thanks for sharing.
OMG OH NO!!!! He has changed the music to CNC music now! I KNEW this channel would be ruined when them CNC machines arrived.
It could be wrong but I heard the music was changed in memory of his father and grandfather
Ya the old music is actually UA-cam stock music
@@danielmclellan7762 this is too. Maybe he's ready for a change? It hasn't changed in like 5 years. Who knows. Maybe he will see fit to tell us, it's not like he can not notice that all the comments are about the music instead of the shop content. 😂
Nice job Adam. I’d love to do my Bridgeport some day. The scrapings are hardly visible anymore. It’s not terrible, but it could use some love. I actually bought the scraper blade last winter because I was gonna make one, but other projects got in the way. It’s nice to see you back on the old machines again. Not to into the CNC stuff
Agreed this channel isn't what it used to be, im out of here!!
What does *DEFL 20 I* mean?
Grate ...thank you liebe Grüße aus Deutschland ....
I always enjoy the scaping. I have a plans sheet for a complicated eyebolt for an antique aircraft that I have made. I thought you might like to have a copy to see how you could program one of the new machines to make it. let me know if you are interested.
scaping? Like.. um.. MANscaping?
I've always wondered if only using one stone on a workpiece would make it run out of spec faster
You always grind flat surfaces in groups of three. In this case, two stones and one workpiece. If you just use one stone and one workpiece, there are an infinite number of spherical surfaces that you could be grinding into your work and your stone, there's no way to know that it's flat and it's much more likely to be a slight sphere. By introducing a third surface, you can be guaranteed that the surfaces are flat if all the possible pairs of surfaces mate together nicely.
@@tissuepaper9962 I had thought I had seen that three surfaces are self-flattening (if lapped together in a graph-theory ring) whereas any chain of surfaces would at best give a sphere (and a spheroid if your technique is bad)
I'll never understand why people have this GREAT old machine and water soluble cutting oil.Those machines were NEVER designed for that garbage..please stop. The cnc machine are designed to use it but even those machines have seals so the water soluble oil won't go where it do'nt belong
I just remembered why I never read the comments, don’t like it then don’t watch it, get a grip and move on, quietly before you embarrass yourself
Good video.Thank you.
Nice Job Adam. I still have my Hand scrapers I used on a German Horizontal boring mill I used to own. And to All the doubter’s yes it helps the axis move much smoother if You have the proper lubrication. Good 👍🏻 Video
I wanted to see the face of the boss who saw what his eager employee did to his very expensive vice, must have been priceless!, "Johnson!!!!, what the fcuk have you done!?", "Sir" says Johnsons best friend, "He is already home sir!".
beautiful work Sir
Finally a shaping video
Couldn't you have just thrown it up in the grinder and surface ground it to true it? Before flaking?
Kudos!! I’ve been wanting to learn scraping I have an older Bridgeport I want to work over,, I’ve seen the finished result on instagram you did a an amazing job!!
Tay nghề quá đẹp
nice
Geezus!! What’s with all the opinionated bs?!? Can’t y’all just enjoy the great video?
I was amazed at how much material was coming off. Thought it was a scratch but that why they call it scrape i guess lol. Nice work!
Good old Biax. They're made in my neighboring town. They also got a monastery there which is unesco world heritage
Thank you Adam
Nice video, it seems harder when you are the machine skimming over the metal instead of just cranking a wheel.
Maravilha de trabalho esta máquina ajuda muito neste trabalho, fica perfeito!!!
Might be a target area for a chunk of metal or a chuck that plops down out of control.
Abom time
Hi 👋 Adam.
Biutiful!! Adam. Como siempre todo a la perfeccion !! saludos desde Uruguay
Is that your Biax power scraper? I realise it's chump change compared to some of the other stuff you've bought for the shop but those things cost an absolute fortune!
He mentioned where he purchased them from at around 29min of the last shop update.
Adam, I see you mark shafts on the lathe where you need to end your cut all the time so why do you feel that marking reference lines on items you are scraping makes you less of a expert? If it makes the job better in the end then it is the better way to go PERIOD.
Me encanta ver el raspado de maquinaria, ojala pueda seguir subiendo mas videos con este contenido. Fan desde hace más de 4 años.
Second!
like a fine watch.
I really like the music. It's as soothing as Adam's voice.
That's a level up for you mate, scraping is an art👍👌🇦🇺
Looking good Like always getting things back in shape and useable 👍
Bonita técnica me gustaría hacerlo aunque sea una vez 🙏👍
i thnk m gong to invest in a power scrapper as ive been hand scrapping since 1970 and my wrists arnt what they used to be. Where did you get your one from ?
What’s scrapping?
Alway a pleasure watch your video Thank you
Out of curiosity, is there any alternative machining process instead of manual scraping to get that oil retention?
That is not actually scraping. It is flaking/frosting , It does not change the flatness or lack of it. He is using (misusing) a scraping tool to do it. Proper scraping is used to get a flat surface(not to get oil retention) then you can add the flaking on top after to get oil retention. As for alternatives, only lapping can get up to the same overall accuracy as scraping.
Es sieht aus wie eine 3D Illusion, Funktion und Schönheit treffen zusammen😃
Using a sharpie to draw lines with a 45 deg triangle really helps alignment of flaking.
Love this channel, been a follower for about a year now, also HI to all the Engineers out there, i`m not an Engineer myself sadly but my Father was so i inherited some of his love for precision and quality, i`m a 53 year old Kitchen Installer from the UK with almost 40 years experience who takes great pride in the quality and accuracy of my jobs, i`m also heavily into ancient engineering techniques, specifically how the so called Dynastic Egyptians cut and polished igneous stone like Granite and Diorite which has a Mohs scale hardness of 6 - 8, there are a good few Engineers out there now who believe, as i do, that these highly accurate monuments and statues were cut on machines similar to lathes and mills, the precision on some of these artefacts is to within 100th of a millimeter yet were are told by the mainstream archaeological community that they were done using copper tools, chisels and dolorite pounders BY HAND, anyone who knows Quartz, as i do as we use it for countertops, knows it can not be cut or shaped using copper or bronze tools to this precision, also under a microscope these objects don`t show impact marks which you would associate with chiselling and hammering, they are perfectly smooth, perfectly square and they even pass the light test with an engineers light test you can`t get that accuracy by hand, many of these artefacts show evidence of tube drills cut at a rate that we can`t replicate even with today`s highly advanced CNC machines, there`s evidence that huge 1200 tonne blocks and single columns were cut using a huge overhead circular saw and Live Centre holes in the bases of 200 - 300 tonne single piece granite pillars, there is an English Aerospace Engineer who moved to the States called Christopher Dunn, his qualifications are second to none in the field of Engineering, he`s travelled to Egypt and other locations around the globe and conducted tests on many of these artefacts and he`s concluded they had to have been cut and created using ancient engineering machines, something we are told never existed in pre history yet the evidence discounts that, there is a channel on UA-cam called UnchartedX presented by an aussie guy called Ben, his channel is dedicated to exposing these incredible highly accurate artefacts and calls for academia to acknowledge that there was once a long lost forgotten ancient highly advanced civilisation that existed before 12.500 years ago and was erased from human history by what`s known as The Younger Dryas Impact, a theory that has since been proven correct and it`s been peer reviewed, my big ask in all this to all you Engineers out there is to have a look at Chris Dunns work and Ben`s over at UnchartedX, see the evidence for yourselves when you get time and if at all possible lend your expertise and engineering knowledge to their work, the more skilled engineers who get on board the quicker science and archaeology will take it seriously, the theory is that in pre history there was a highly advanced global civilisation that had the knowledge and technical ability to build these ancient monuments and that the Dynastic Egyptians only uncovered, inherited and repurposed these sites thousands of years later once Earth`s climate settled down and human population and society was rebuilt, a big ask i know but i know these guys would appreciate your time and skilled knowledge to either agree with their hypothesis or point out errors in their theories, thanks for reading all this, i appreciate it cheers.
