Hi Abom. Thanks for high resolution and good light on your videos.

[@vintagespeed]

your videos are a kind distraction right now Abom, thank you. it's been a rough week.

[@melloman8210]

Same. Hang in there dude 🤘🏻

[@wheelitzr2]

Same. I totally understand!

[@GrantHorvatGolf]

I'm here for a chat if you need mate.

[@MichaelD-fn5lv]

☝️☝️☝️same! Good vibes fam, hang in there men! stay focused & keep your eye on the prize

[@-Kreger-]

You all keep your heads up. Good and bad times ahead for us all. Just get through the bad and it’s a matter of time before you turn it around to the good.

[@jeffh1269]

For all the people asking about where the grease grooves go. You have 2 parts, the gear and shaft. The gear obviously doesn't have a zerk. That leaves the shaft. Use your brain for CS.

[@stevendupre2792]

Well said.

[@grntitan1]

😂

[@johnellinwood267]

There’s a grease hole in the shaft. He made it 5 videos before this one, in “New Shaft for Bull Gear”, and explains it in that video at 9 :25.

[@PhilG999]

Bronze bearings are great! I sold a LOT of sintered oil-lite ones back in my Mill Supply days. Sometimes I would have to take a Roper (gear) pump apart, pull the bronze bushings out, and put Graphite ones in. I was the only guy in the place that could do it consistently! You couldn't press the Graphite's in, or they'd shatter. As strange as it sounds, you had to *tap* them in with a dead blow hammer! Had to get it *just* right. If you did, every time you tapped it it would *creep* a little. The other guys gave up trying because they ruined a LOT of bearings! I got to the point that I'd take 5 bushings from stock (pump took 4) and put one back when I was done! #5 was "insurance" 'cause the stock location was two floors above and having to climb those stairs up and down was a PITA for ONE bearing!

[@johnwebberley6710]

Always good to watch a profesional at work especially one who takes such care to get things right

[@avoirdupois1]

Anyone who sees that gear will know that it was made with care and mastery. Great demonstration of this process!

[@ÁREAJ27]

Olá a todos!!! Estava aguardando a continuação deste trabalho!!! Abraço daqui do Brasil a todos aí!!!

[@The_DuMont_Network]

Bom Dia!

[@tropifiori]

Gorgeous. I love turning brass

[@foxwood67]

Projects like this are what makes this a great channel. 👍👍

[@brucedryden7207]

Nice work, I like how you just dived right in without a lot of verbage , also loved the shot with chips flying at the camera. Thanks for sharing!

[@MichaelD-fn5lv]

Was about to say the same- I like that he jumped straight into the action. Intros are important, don't get me wrong, but those of us following the projects know the deal already. Everyone else needs to go back to the start of the project 😎

[@robertcarney6259]

I have found in my time in rotating equipment when machinist grove the bearings and seals always found high spots around and always decreasing bearing and seal clearances, finishing the bore after details always helps? my experience as a assembly mechanic at sulzer. found a lot when pressing in parts gaul’s would pick up and decrease bore clearance and hard to see until final assembly, so if precision matters final machine after pressing in helps final assembly for clearance achievement. my experience, thank and love all you. thanks Adam for your wonderful video very humble teaching is needed in the industry.

[@robertcarney6259]

brass if I remember a good rule of thumb is .0005”-001” per shaft diameter clearance ID. and OD .001”-.002” interference on most parts stationary for interference fits is industrial norm. rotational high speeds interference changes by knowing materials and thermo dynamics.

[@spaight711]

I was hoping you’d claim a new bore and turn the OD of the hub so it would all be true to make it easy for “the next guy”

[@jameshodgins1937]

I dont comment much on your videos but do enjoy them and learning from you. Thanks for sharing.

[@RickBaconsAdventures]

CLASSIC Abom content right here, heritage

[@AlexDeGruven]

Man, remember when we used to make really cool stuff in Detroit? I remember. Happy to see some of it coming back at least.

[@Pyle81]

I can remember sitting and waiting on mill rights to get a broken part out of a GM stamping press. Then hurry up and get it tied down and fly across town (Detroit) to a waiting machine shop. And then told "Go take a nap,Well wake you up in 7- 8 hours to have you take it back. Those days are LONG GONE, As are the machine shops all over Detroit. Thousands and Thousands of Machinest, Fabricators, Welders, and Fitters. All those jobs are gone, Good paying, skilled labor. When you could make a dam good living and enjoy life.

[@grntitan1]

Nice job Adam. I appreciate the Tuesday evening videos.

[@sumikomei]

I never really thought about making small interior linear grooves with a lathe like this, this is actually really cool.

[@iranausley8150]

It's a pleasure to watch a master machinist at work. This is an acquired skill that takes years to reach your level. Of course, you had a great teacher in your father. Love watching your videos.

[@joekanicki5306]

I’ve watched your videos for over a year w/o comment, but I just had to say this one was really great!

[@Metaldetectiontubeworldwide]

Keep'm Coming Adam ☆☆☆☆☆ Your videos are my distraction of suffering covid at home alone and on top of that a flaming heatstrike outside ...its hard but you keep me going!

[@LabRatJason]

Man, there’s just something about the look of fresh turned brass/bronze. It looks so good! Gives me a little bit of gold fever I think.

[@ChristophersOverTheTop]

Always good to watch another great fabrication.

[@waynep343]

When centering gears with worn bores have you considered grinding an inviolate shape on a piece of regular steel to mount in the toolpost to allow you to center the gear mid tooth kinda like a thread gauge wire set. Bring in the cross slide till the bar or ground shape fits 1/3 to 1/2 down the gear face. Zero the dial. Back the cross slide out. Turn the chuck with the gear in it half a turn and bring the cross slide in to see if it touches at the zero on the dial..

[@chrisarmstrong8198]

I was surprised that Adam didn't indicate the tops of the gear teeth prior to boring. It's the gear teeth that need to run true, not the bore. (Although, in practice, the bore and the tops of the teeth were probably turned in the same set-up and would be dead concentric.)

[@makepartsUSA]

interesting idea. but for a gear that old is the pitch circle face contact area any more accurate than the bore?

[@an2thea514]

The face of the gear teeth are never in use, so it's quite possible they machined this coarse, milled the teeth and then chucked it in any machine to make a bore, so it's quite possible they are not concentric either

[@endemiller5463]

Love the start. Jump straight in. We're not here to muck around!

[@ritaloy8338]

Thank You for making this video and all your past videos available for our viewing.

[@ravenwilliams2370]

i lone watching real masters at work and you sir are one of those in my book ... well done

[@xoxo2008oxox]

I hope your friend can get you some footage of the linen machinery that uses this and the previous gear repair!

[@ScoutCrafter]

STILL the best machining content on KZbin!

[@gitarowiec100]

As much as i hate imperial measurments and placing them even near the word precision as much i love to watch you work. Especially long time turning. It is just so soothing to watch the lathe leave the part with mirror finish.

[@joewhitney4097]

Great repair Adam, love the attention to detail. I'm sure the customer appreciates it as well. Thanks for sharing.

[@andersjjensen]

I love when you do brass and bronze work. The chips break easily and evenly and the finish is so good I feel like licking it :P

[@BruceBoschek]

I love to see a project like this from beginning to end an out the door. Useful discussion and explanations. Thanks.

[@Joserocha-wm9de]

No matter how good Adam's new shop will get , his old shop will be always the old shop ... Im sure there is many good memories , machinery that he will never get rid of it ( sell ) and many tools belonging to his beloved Father .. Always a plessure to watch your videos , very detailed and very well explained 👌

[@rodneywroten2994]

beautiful work Adam

[@idriwzrd]

That electric press is so cool!

[@cnosprandt5155]

Beautiful bronze bushings - great work!

[@michaelkading240]

Your thought process is great.

[@KimbrellBrad]

Nice work and great explanation of other ways in case you have a tight fit or may have warped something if welding on it. Thanks Adam!

[@emilgabor88]

Nice job. Like you said, boring after the press is a excellent choice. I prefer that even if it takes more time

[@kevinknight470]

Another good video, watching a master doing his craft. Not too much talk, just perfect balance. Thanx Adam. 🙂

[@frankfiederlein4233]

Just making similar ones yesterday but there for a reducer shaft and a sleeve bearing I'll try and remember to get a picture of them love the video keep up the great content

[@frankfiederlein4233]

Sorry I thought I could attach a picture of the bearing bushing but I'm not that KZbin hip

[@russellwhite6795]

hey brother. nice video as usual. that finished bronze looks real pretty on camera. you're experience really shines with this type of job where an understanding of the stresses the part will see in service allows using tolerances that are "good enough" and let's a shop turn the work around quickly for the customer who needs it... 👍👍👍

[@elanjacobs1]

Knowing what's "good enough" is part of being a machinist/engineer. The place I work at specialises in gears and I was trying to explain to people commenting on part 1 about why there's no need to bother indicating the gear teeth for runout when the bore is going to be more than good enough.

[@Narious324]

Love your work. So interesting and fun to watch. Thank you for taking the time to make these.

[@vicmiller7191]

I do like watching the Master at work. It's great to see you back to making stuff. Thanks For Sharing

[@michaelhowell-walmsley3850]

Nice change to the format. With the audio. A pleasant surprise.

[@Davidthomasv8]

Beautiful workmanship adam fair play .

[@buidelrat132]

I like this video editing style, thanks for mixing it up sometimes, great job as always.

[@BedsitBob]

If your lathe can cut a very coarse thread (say 1 TPI), you could cut a spiral grease groove.

[@garbo8962]

Years,ago I worked in a 65 man maintenance shop as a sparky but was always interested in watching guys on la the or milling machine. Only ever saw one super dedicated machnists make spiral grease grooves to better spread out the grease. He also had some think he called them polite brass bushings in his tool chest. They had black spots that supplied great lubricating.

[@robertlewis4666]

I love machining brass.....but I HATE cleaning the chips, cos they go everywhere! Nice job there Adam.

[@mikedyson7330]

Nice work . I like CNC but don't switch totally from manual your my inspiration for me and my small shop I'm 68 and always learning . THANKS.

[@thomaschandler8036]

Good job Adam, enjoy your work

[@comictrio]

Very nice to see quality work done by a master.

[@bubbernator1]

And I thought "measure twice, cut once" was just for wood butchers like me. Well done, Adam. I'm not a machinist but you've taught me a lot. Thank you.

[@fergusonhr]

Thanks man, I too needed to watch you at work...your calm attitude made me relaxed after a crap day...

[@125spectrum]

[@ellieprice363]

Beautiful accurate work as always. Love the finish on those bronze bushings.

[@chowardlaw8417]

Ah, reminds me inescapably of the time i spent at Aberdeen, Ordnance Officer Basic and then MOS course. By the time i was done, sort of wished I was a Warrant Machinist. But my career, military and otherwise went in a different direction. Still enjoy seeing good machinist work. And just so much enjoy watching bronze - the material is just so beautiful.

[@willjosephson]

Thanks for your comments on what matters and when precision is important and when to stop chasing perfection.

[@TomTalley]

Thanks for bringing us along on a great project.

[@Stan_in_Shelton_WA]

24:20, I appreciate you giving all your viewers credit for assisting you. "That step we turned in the O.D."

I remember my days as a millwright machining bearings out of oil-impregnated bronze, and digging chips out of my bellybutton at the end of the day. :) Good times..... I guess :)

[@zumbazumba1]

Dancing the hillbilly dance when hot blue chip fly's trough air and drops trough collar of work suit right on your neck :)

Long time lurker... This video got me randy. The production of your videos just reached the next level. Thank you.

[@prpunk187]

Oof a abom video right when I sat down to eat nice love the videos keep up the good work

[@tomoakhill8825]

I enjoyed this so much. I love your videos. It makes my day to see one. Thanks. I so enjoy watching your precision. Bumping 8:30 to get the three linear grease grooves _exactly_ 120° apart is so unnecessary. Being off by ±10° will make no difference to the greasing of the bearing. Nonetheless, there is Adam getting it perfect. I love your work ethic man.

[@jimzivny1554]

Great project, nice finish on the bronze, with some grease should last a long time

[@JimWhitaker]

Thanks Adam. Interesting as always.

[@StevenAndrews]

Even the lathe wants to do shaper work...

[@JTLaser1]

My Mom worked in a steam laundry in the 70s and I got a few hours of part time work, I believe that gear is for the sheet pressing machine. It’s a huge thing that damp sheets go in one end and pressed sheets come out the other. Even as a teenager I was terrified of that thing!

[@andersjjensen]

By the looks of it that machine was designed in the 40s... which means that worker safety was an afterthought a few decades later. So yeah, I get why you'd be terrified of a machine that can turn people into pressed sheets about just as fast as it can turn damp sheets into pressed sheets :P

[@JTLaser1]

@@andersjjensen Yeah, I was clueless enough to be fearless about most things, but that machine….. And I visited the newspaper once, EVERYTHING there could kill you!

[@kenore4003]

Spent years in the printing industry. Ran magazine and catalog presses. Backed several people's fingers out of the rollers. When there is a couple of 150 hp motors running them your fingers or anything else wouldn't even bother them.

[@paulcopeland9035]

JT Laser.....yep, I believe you are correct. If you review his Facebook vids, there is one which shows him at Joe's shop with a large (16" or so) roller destined for this gear and project.

[@martineastburn3679]

Looks like Si Bronze to me a beautiful gold finish. I made fancy end nuts for my 2 lathe draw bars.

[@bcbloc02]

Those bushings turned out pretty.

[@4pawsforge273]

If all of those chips were moth's, it would be like "Silence of the Lambs" when Clairice showed up to save the Senators daughter. I wish I had a lathe and dang Abom! Love all of your content. It makes me smarter about everyday stuff and I say thank you for that!

[@oldcatmech]

At 28:58 you state that you could make the bushings .010 under size then re-chuck in lathe, but then you have set up time again! That would be a good reason to have cut true the gear outer bore while it was still in the lathe when you cut the face and rechecked the run out of the bore minus the bushings! There was more area on that side to chuck too, if re-install was needed!

[@MikeBaxterABC]

Nice work Adam! ..

[@d00dEEE]

Brass and bronze are so much fun to machine, just use HSS with zero rake and look at the beautiful finish....

[@blankroomsoup666]

HSS works well, but you should try some polished carbide inserts. They will last pretty well on soft materials while leaving a mirror finish.

[@mfc4591]

Looking good. Brass is great to machine, watch out for those hot chips though, and sharp stuff!

[@petehowlett3966]

Nice to see you breaking out the HSS tools.
