Can’t wait to see a gearbox maintenance video. The last time you did one I was fascinated by the gears and the amount of oil needed. This machine is going to become better and better as you go. I appreciate the watching you clean things up at the beginning. Honestly you can lower the music volume. Hearing the sounds of cleaning and stuff is great. Keep up the awesome work, Adam! 🤘🏻

[@John-gt5fm]

Adam I have a pacemaker about twice as long as yours in our tool room at work. Our production lathe’s the tool post is about 400lbs I am one of the few who takes the time to clean like you are doing. Pride in our profession comes standard for some.

[@Garth2011]

She's alive ! I agree, bearings, shims/bushings and maybe some gears are worn. I heard some added noise when the gears were working on coast so could be the bearings or shafts are beyond reasonable. I think if there is going to be a long life in the ABOM79 shop, I'd plan on replacing most of the higher wear items under the hood. That is a nice and smooth slide for sure.

[@yambo59]

Cant wait to get a look inside the gearbox of the A.P.

December 24, 2122 AD: Discovered beneath the ruins of Old Pensacola Florida an intact early 21st-century machine shop. The shop contains a mixture of mid 20th-century and early 21st-century equipment. All equipment is in immaculate condition. Except for a thick coating of dust, much of the 21st-century equipment appears as new, as if it was installed new and never was used. It cannot be emphasized how important this find is. It is rare to discover such a complete workshop showing the transition from manual to computerized creation of components. While today such parts creation would be accomplished via AI and 3D printing, it is educational to find a complete transitional machine shop in such museum quality condition. It remains a mystery as to why this equipment was never used. Records from this period indicate that this was an immensely expensive assemblage of equipment. A further mystery is the glyph of Abom79 affixed to every smooth surface. Researchers are attempting to ascertain if this has some sort of hidden meaning, or is graffiti left behind by an urban explorer in the intervening years, we may never know. The Old Pensacola Preservation Society thanks the City of New Pensacola county council for it's help preserving this once in a lifetime find for future generations. It is unlikely that a virtually untouched discovery such as this will ever be found again.

As usual the archaeologists concluded it was a tomb and temple to worship the gods. And the structure was made using copper chisels

[@amarshall87]

Just finished Christmas Eve festivities, cleaned up the house and wrapped the last of the presents. Now I get to sit by the fire and watch some Abom79 and listen to the relaxing music. Merry Christmas!

[@brianmoore1164]

Watching you lovingly pour work into these old machines is a beautiful thing. I can tell that you want to give full justice to the craftsmen that built it and worked on it all those years ago. I can't help but believe that they are smiling down on you from Heaven. Merry Christmas and thank you for all the great videos.

[@kevinhornbuckle]

Kind words. And true. Merry Christmas.

[@brianmoore1164]

@Kevin Hornbuckle Thank you, and Merry Christmas to you as well.

What a nice relaxing video , my complements regarding your music choise ☆☆☆☆☆ Realy love the old western banjo music, as an european guy 😅 Secretly having the Anerican Dream myself .. Starting to hate the west Europeanen way of life 😢 , getting to hectic ..to much taxes and no freedom... Grtz from the netherlands Johny geerts

[@johnmiller8201]

Adam its funny that I have worked on this old machinery for the better part of 32 years and now im running a cnc lathe in a small shop here in Akron,Oh. At any rate just wanted to say to check your input shaft to the gear box experience has taught me that most of the noise causing damage is in the input but only you can best tell with your ear and a piece of half inch conduit just probing around. best of luck

[@kdaniels98]

Adam, if you still have that 3D printer, you might consider printing bolt hole guard inserts to keep them from filling up with gunk. It looked like a lot of hard work getting that machine so clean. Cheers and Happy Holidays!

[@kevinknight470]

Could you fill them with silicone.? The silicone would pop out easy when needed to loosen screws. 😃

[@wagsman9999]

Sweet! I can imagine the lathe changed the world as society entered the industrial age - it would be fascinating to read a book on the history of the lathe.

[@jamesdstallard8743]

There's a man making full use of his CRC degreaser sponsorship 😆

[@mannys9130]

We measure liquid degreaser usage in units called "Obrochtas." So the proper amount to use per job is roughly 1 Obrochta of degreaser/solvent. This unit is primarily intended for use with brake cleaner solvent. Particularly nasty jobs may require 3-5 Obrochta of cleaner. On the other hand, sometimes you only need 500 milliObrochta of brake cleaner if you just have to give it a light little "how ya doin' mama" to make sure everything's nice and clean. 😎 Adam is using 1 or maybe 1.5 Obrochta of degreaser here so that's an appropriate amount. Pretend like you're the Old God and the dirt is everyone who couldn't get on the Ark.

[@billybike57]

I’m not a machinist but I find watching your channel very cathartic to watch. Keep on keeping on!

[@PaulBenedict1]

Almost like he planned to have his new lathe be his Christmas present! Merry Christmas and Happy New Year everyone!

[@afryhover]

Beautiful seeing it move some metal! Well done 👍👍

[@h2opower]

I'd be willing to bet this machine has never gotten this type of love since it came off the show room floor🥰.

[@bcbloc02]

I am suspicious that clatter is coming from a reverse bell mouth condition on that chuck making it knock while in the cut. putting that 4 jaw on may make it sound a lot better. Alternatively could use your tool post grinder to straighten em out and see if it fixes your runout. My 3 jaw never gives me any trouble unless it’s on something thin wall. Solid you just crank it down and it will take whatever cut you want to try.

[@Orgakoyd]

Reverse bell mouth? So bigger at the back?

[@bcbloc02]

@@Orgakoyd yes that would let it hold the part but when you start pushing on it it will shove it to each jaw as it goes by making a rythmic knock

[@Orgakoyd]

@@bcbloc02 I understand what you mean, just never heard ''reverse bell mouth''. I always thought chuck jaws bell mouth at the front, and this is the condition they flex into when tightened. Didn't realize reverse bell mouth is a thing? Unless someone ground it that way?

[@Wastedwu]

I know this is a special video for you, I did not expect it to be a christmas presant four us, your viewers. Thanks.

[@markloving11]

Never clicked a video sooo fast!

[@Airtight215]

Back to the basics of where we started, I like it. Can’t wait to see what comes off it.

[@heardashot]

I've had time to consider this issue further having consumed and digested a rather large portion of turkey!!...😆😆👊 I don't believe the run out on that three jaw is issue with the chuck. I believe it is the main bearing on the chuck side of the gearbox. When you critiqued the chuck, splines feel good during nip up, that would suggest chuck in good order, looks like done little work. It would suggest the bearing is the culprit considering that noise. Food for thought!! Seasons Greetings from Ireland!!

[@lexpee]

Nice old machine, I'm afraid it needs even more attention and care. That sound is clearly a sound of a worn out gearbox. That gearbox needs an overhaul. Replacement of all bearings. not surprising after 80 years

[@jiversteve]

Merry Christmas from across the pond.

[@michaellee6168]

A full rebuild would be awsome to see. Have a Merry Christmas all.

[@apistosig4173]

the APs first turning was very impressive! gawd I'm jealous again 😋

[@v8packard]

Adam, There is a Sherwin Williams color, Urbane Bronze SW7048, that is a good match to the older dark gray colors on machines of that vintage. You can get it in the enamel in small cans. It would go well on those parts of the lathe you have cleaned. Thanks for everything you do, Merry Christmas.

[@lloydbaker7099]

Great to see an old machine brought back to its original potential and see someone who knows how to appreciate it

[@tcseacliff]

I really like the look of this lathe. Hope you can make some vids of the gearbox investigation!!😮

[@beaversixniner]

Time for a new shop tour!

[@NSResponder]

Merry Christmas to you, Abby, and your whole family, Adam. Thanks for the education and entertainment you give us, and I hope you have a fantastic 2023!

[@BrianEltherington]

Merry Christmas Adam and Abby. Thanks for another great year of content. Something very satisfying about cleaning up an old machine, seeing the scars, and wondering what tales it would tell if only it could talk. That Pacemaker is a beautiful machine. Love the old Art-Deco styling. That tool holder has similar design elements and goes perfectly on that machine.

[@patrickcolahan7499]

So glad that you are back on the Pace. Hoping we won't go months before we see more. Thanks very much for sharing.

[@1911wood]

Nice work. Those big cuts with a nice finish. Looks like hours of fun ahead. Oh hey, tell Abby her Chiefs won.🎉

[@Adventure_Van_Upgrades]

merry Christmas , thanks for the quality videos as always

[@Hendreh1]

Greetings from Germany 🇩🇪👍

[@dan-cc5qn]

I have 3 pacemakers and I consider them lighter duty compared to American Type C’s I have but they are reliable and easy to work on and they get the job done and hold perfect tolerances I recently had that brass nut that rides on screw for cross slide break in two pieces so I have a parts machine and used it to fix my lathe and I did it while running my other job and took me two days to break down clean and replace and it faces really nice now and isn’t leaving a mark in center

[@ianmurray3820]

Hey Adam I know you gotta keep moving, changing things up and learning new stuff- namely cnc machining ( a completely new and very frustrating discipline all by it’s self ). But hands down this is by far your best work.. old school machinery are things of beauty.. I appreciate the precision of modern tech, but how much more rewarding is sneaking up on a dimension with a set of callipers and a mic’ , plus if you overshoot it’s your own fault rather than a glitch in the machine…😁❤️💪🏻💪🏻💪🏻

[@elmarqo_3448]

That was great! We have been waiting a while to see the pacemaker throw some chips. Merry Christmas

[@jfa689]

I guess we are going back to basics Keep learning

[@frfrpr]

Great video. The filming was as good as usual. The music during cleaning was a plus. I enjoyed the video. Thanks

[@TheJohndeere466]

We have a lathe like that at work except its a duplicating lathe. It has a hydraulic compound that follows a sample shaft that is mounted back behind the machine. I used to turn 8" dia x 36" 4140 shafts for overhead cranes. I would take .750" cuts at .030 feed.

[@TheJohndeere466]

We use a Mazak cnc lathe now and it is much faster for finishing but the old american will eat it alive for roughing.

[@johnsharkey2699]

Merry Christmas to the booth family

[@h2opower]

Can't wait to see what's causing that noise as that's when things are going to be a true learning experience as we've already heard the noise so now time to see what's causing it. This way we all will learn from this as we get to see and inspect those guts along with you. Take care and enjoy this beauty.

[@desolatemetro]

Awesome! 👍 Definitely enjoy watching you work on this machine when you have time.

[@tannerhoward5974]

I ran a pacemaker at my first job. Normal rughing was one revolution of the hand wheel about .020 feed without strain cutting 4140. The lathe was army surplus off a Navy ship and had a load meter that we thought was broken till I accidentally pushed it with a much harder feed.

[@campnut6076]

Ran an American 20 x 76 "Style D" for 14 years before they shut our mill down. Great lathe, made a lot of pump shafts, agitator shafts, bore couplings and resleeve bearings in that lathe. The feed would occasionally give me an issue when trying to run heavy feed to break the chip on 316SS. Other than that it was a great machine. 4 jaw chuck of course gives more options to hold irregular work pieces also. Good luck with your project.

[@DH-ds5mg]

Good video. Looking forward to seeing the clutch works and inside of the gear box. Great work

[@ronnydowdy7432]

May need bearings. Some of the 3 jaw chucks are adjustable from the backside of the chuck. I think I would indicate the od of the 3 jaw chuck to just see if the run out is .012 also.

[@garyknight3019]

Merry Christmas Adam…thanks for all the awesome content you have shared this year.. Hope you and Abby have a fantastic day doing whatever makes you happy

[@paulcooper2897]

Suggestion, if you read this ... on the compound, make yourself a plug for the second unused tool post mounting hole. No sense packingnit with chips until the day you need it! Great to see the Pacemaker up and running! Thanks for sharing 🇨🇦

[@FreedomFromIgnorance]

Sounds more like the head stock bearings beating themself to death when you put pressure on it.

[@millwrightrick1]

My thought too. 80 year old bearings are just that. Time for a replacement.

[@jimmyboles3409]

Great to see a little TLC on the good old iron and making some chips in the miss of all the other projects you have going on keep up the good works!, y’all have a great Holiday!

[@tmacie2]

That pacemaker is nice! I've also got a headstock noise and cross slide feed issue going on with my Cincinnati Hydrashift. I think the noise is pump related because it doesnt always shift gears. They feed issue I'm thinking is related to the "quick reverse" on the cross slide. Lots to learn!

[@jeffnevius]

It will all come together takes time.

[@ellieprice363]

Good to see that big boy making chips again. Assuming the internal scroll on the three jaw is in decent shape all it needs is careful grinding to true them up. If properly stressed with an outer blocking ring the jaws should clean up to .003/.005 total runout.

[@jamesburba1995]

Merry Christmas ! It's good to see the ol' Pacemaker making some chips.

[@tropifiori]

A gorgeous shop

[@phalanyx3478]

I keep a 10" wrench plier in my back pocket and its replaced every wrench I use that doesn't require more than a 10" handle's worth of leverage. Works great for grabbing hot material when bench/belt grinding, parting, bending sheet metal, or wiggling keys out of a tight keyway. Its not as fitting to this machine as an older style of wrench, but I can put enough beans into it for any compound nuts on any lathe.
