Compound Rebuild Begins for American Pacemaker Lathe
ฝัง

- 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.
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.
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.
Glad to see the pacemaker getting some love. I am still looking forward to some big heavy cuts on it. 🙂
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.
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.
Interesting the scraping is 0.002" deep. I would have thought it was much shallower.
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 TH-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.

I can hardly wait to see that big boy making chips
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.
That’s a super idea! I like the randomness of the pattern. It reduces long term wear and can’t be matched by any automated machine. I guess there’s a reason that machinists have been hand scraping for …well… EVER!
have you considered getting a vapor blasting cabinet? seems like it would be an excellent addition to your shop for cleaning parts
Good video.Thank you.
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.
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+
Going to be a good one
Abom time
Perfec
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
I have to think that a CNC program could do that pattern with a fractal math component to imitate the hand scraped look.
Yeah, you could make the pattern look right, but most CNC machines won't hold the tolerances required. Each pass with a scraper is probably removing .0001", so you'd need a really really good machine to do it.
Post the math! What good is a comment without the proofs? Many of us watch this to learn. If you post your proofs we all can learn.
@@alexwbakker The video says he is removing 0.002" which seems a lot more?
@@machinists-shortcuts he’s probably doing multiple passes to get the geometry right. A good CNC could definitely get him closer before scraping. On anything I rebuild I like to get within .001 before scraping because I only have a hand scraper and it usually takes me 8-10 passes before I can get things “flat”. I think you can move more metal with a biax, but I’ve never had the luxury.
the flaking is for oil retention ?
Yes
Second!
I'm curious if a conventional oscillating tool, particularly a battery operated one, could be pressed into service as a scraper. I suspect not but I'm curious if anyone has ever tried it.
There's actually a TH-cam channel, Cà Lem, that did something similar with a reciprocating saw and it seemed to work quite well. Search "DIY - CHEAP Power Scraper".
The biggest downside to that mod though is the stroke length not being adjustable. It's important to adjust the stroke length as the optimal length for rough passes isn't the same as for finishing passes.
Yeah I've done it plenty of times with a small air ginder with a 90degree head and a 1' grinding pad. You don't really need the anal-intruder 4000 all the youtubers use, it's jut nice to have.
@@sheikyerbouti83😂
Aren't your precision flat stones truly only precision and flat until the first time you use them?
I agree!
they must be rubbed together, which is a self correcting operation. Watch robrenz video for a deeper explanation
Not really. Precision when new, a little less precision after using. Love mine. By rubbing together after use they’ll last a long time.
@@ellieprice363 and *before* use👍
No signature music today :(
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 TH-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!!
Do you have a 3rd precision ground stone? It takes 3 planes to maintain flatness.
Plus I wouldn’t rub my stones together over the workpiece. Any grit displaced by the rubbing is going to fall on the surface I’m dressing.
2 stones = 4 sides so that's covered
It's not a precision plane that he's trying to get. The objective, as he repeatedly said in this and other videos, is just to know off high spots. No need for a an highly precise stone.
BTW, asking if Adam Booth has "something" related to precision machining shows that you have never his videos. His stash of old and current tools is remarkable and enviable.
@markshort9098 he never rubs the the coarse and fine sides together. 2 stones and 2 sets of sides
@@stevenslater2669 Misplaced OCD. Stoning will leave abrasive on the surface anyway but that's not a problem, since you are actually doing an abrasive job. Then the work is cleaned of any residue.
I used to look forwards to a Saturday SNS but lately this episode took about 4 minutes to watch.
Those days are long gone. Oh well. Try Cutting Edge Engineering.
@@andrewterry8092 i am already subbed to CEE love his outtakes at the end lol
Mark Mawson. Yes 4 minutes. I have followed Adam for years but the last 12 months have not been anything like a machining channel. Just a lot of chat.
@@johnsawyer2516 totally agree with you, i know he can't make machining jobs up out of nowhere but he says he has projects to do but he puts 24 minute videos out about cleaning and flaking some metal how boring.
@@markmawson1 hey, buddy, here's a secret. The vast majority of time a machinist spends in the workshop is *not* spent running a machine.
“right here” “right there”. lol. just too much right there.

Can't really call that cross hatch, it's more like cross diagonal flecking than actual cross-hatch.
I'd like to see some links to the scraping that you've done.
@@vandyFixer it's just a correction with no mention of skill or results.
If I call a Tractor a car and you say "That's not a car, that's a Tractor", I wouldn't need to see you making a car now, do I?
Same thing.
Honestly you can enjoy someone’s content and still critique their work in the interest of accurate knowledge and positive feedback, ideally without the mega fan echo chamber going in to mindless protection mode.
@@an2thea514 I disagree with the logic of your second sentence and its applicability but if one is going to correct someone's effort, couldn't they be less condescending and give feedback based on experience and context for the critique?
@@MrPwnageMachine You are correct Rick but I am not sure that the comment was made by the OP in the interest of accurate knowledge and positive feedback. It didn't sound that positive to me and usually, when people do give alternatives or suggestions in the comments they qualify them with the experience that they personally have. Otherwise, how would we know that the comment was helpful and accurate?
Time to leave the channel - not the channel I joined up to see it’s all about product placement now - loved the old style channel, even the music is grating on me. Maybe you need a different channel for your CNC stuff most people don’t have that equipment in there home shop.
You came to say this on a video of him scraping the cross sled of an old pacemaker? Most people don’t have any of the equipment he has in his other shop at home either. If you don’t like it, don’t watch. He’s obviously not headed the direction you want. Rather, you don’t seem to want him to go any direction and remain stagnant. Things change.
I tend to agree.
I appreciate that CNC is a good thing for production runs, but it's also, IMO, boring.
Manual machining is the interesting stuff, for me.
@@uhavenosushiExactly! What about this has ever been “home shop” besides the fact that it was at his house? He literally inherited half of his family’s full blown machine shop and it wasn’t an atlas mill and a 9”south bend.
Odd you waited until he's restoring an ancient manual lathe to make this comment🤔
K. Bye.
Why did you change the theme music. Go back, pls.
I’m here for the machine work not music 😡
Sorry Adam, but..... this chinese flaking method, without the correct rebuild to the original Specs of this machine, is in my mind,a waste of time and material.
Thats not the right way, to do this.
🙄🤔
Where there was no oil there is now
It appears there are more oil reservoirs than flat ground bearing surface remaining. Maybe the pattern is not as dense as it appears!
Are you saying that it wont work or are you just saying your opinion? Oh also scraping is scraping, I don't know what you're on about with the racial slur?
@@musicbro8225 scraping is not scraping. Chinese Machines have often nice sraped patterns, but not correct scraped Flats, nor correct arcs, or correct dimensions.
Just to look a Like, a propper built machine. Thats not racist, thats a fact, i have 2 such machines for myself!!!
Sorry, but oil pattern scraping is not worth the time, If the geometry of the machine is Not correct.
Its Like you bring your car after an parking Crash to a Body Shop, and they only paint it, without any straighten the Panels, Bring Out the dents an scratches, without filler, rust fix and so fort.
You can do things in two ways, the right.......and the wrong way.😉
@@schwellenzaehler4564 So you're saying that Adam, who is a third generation machinist, who has been to a course on scraping doesn't know what he is doing?
Your problem is not even with the scraping, it's with the surfaces where the scraping is being done so scraping IS scraping (lol). This lathe was not built in China and it was built well so you can trust the wear marks and whatever measurements or tests Adam has done to come to his judgment so relax with your saying he is doing it wrong, he is not doing it the wrong way... Perhaps he just wants to get the lathe working so he can then decide what else, if anything, needs to be done.
Geezus!! What’s with all the opinionated bs?!? Can’t y’all just enjoy the great video?
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?
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?
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!
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.
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 like the regular intro better
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.
this is the content i love to see.
quick clean up to put her to work!
Thank you for another nice video.
It’s amazing to think that that old beast could still be making chips in ANOTHER 80 years.
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. 👍
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.
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.
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.
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!
That was fast and will hold oil. Good job.
A little blue would help show what you are knocking down.
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
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
Can that center post be removed? The entire surface looks like it needs to be milled a few thou. Clean your stones.
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 👍
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?
What an amazingly thorough job man you do very good work.
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.
Looking really good. Will be nice to have the Pacemaker back up and running. Thanks very much for sharing.
YOUR DOING GREAT SCRAPING, ( I THINK ) PATTERN LOOKS GREAT
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.
Hi Abom,79, could you use your CNC milling machine to do the hatch pattern ?
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
I seen you were looking for a oil gun Keith Rucker has one you should contact him.
Nice work on the flaking. Thanks for the video.
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.
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.
Finally some elbow grease. Great job Adam.
I like the pattern. Thanks for sharing.
Do you know what material the gib is made of?
What does *DEFL 20 I* mean?
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.
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
nice
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'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)
beautiful work Sir
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!".
Finally a shaping video
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!!
Couldn't you have just thrown it up in the grinder and surface ground it to true it? Before flaking?
Maravilha de trabalho esta máquina ajuda muito neste trabalho, fica perfeito!!!
Thank you Adam
like a fine watch.
Hi 👋 Adam.
