Bore & Bush Bull Gear
Vložit
- čas přidán 20. 06. 2022
- This will be a 2 part video. This first video will show the boring and machining a new bushing for a bull gear. We'll set up the gear in the Monarch lathe to bore the ID true, then machine a new bronze bushing with internal grease grooves, then press it into the gear.
Second video will show machining the new shaft that this gear rides on.

Dont you love it when a repair you performed years ago come back to see you? Its been out there doing its job for decades and has finally worn our. Your repair was good. It lets me know I did a good job.
Thanks for the video Adam. I have owned a 12X36 inch lathe for 40 odd years and while I have knocked out many jobs for the farm in that time I never really knew how to use it properly. Thanks to you, Keith Rucker and Keith Fenner I have learnt so much. It has been like going to trade school for this 76 year old. I now know a lot more than I did 10 years ago, but I still have a long way to go. Many thanks to you and your colleagues for all the tuition. It has been a very interesting journey. Kindest regards from Australia to you all.
Same sort of thing except for a young guy. I fixed things and made pieces with a lathe for farm type stuff since I was a little kid, Adam and Keith Fenner taught me all the knowledge which I could immediately put to use since I already was familiar with the machines. Now I am doing much fancier and better repairs and have machines of my own!
Your Dad and grandpa would be so proud of you!
I love seeing things like a large powerful lathe being used as a hand-powered shaper. That's real machining and a real education!
I screwed up the dis-assembly of a spring-loaded retraction mechanism on a sun awning and the runaway rotation stripped the teeth off of the pawl bevel gear. I mounted the gear in the chuck of my recently purchased vintage Craftsman 101/Atlas 618, turned the threading tool 90 degrees, set the compound and re-cut all of the teeth with many passes. The gods of Machinery’s Handbook smiled on me, and the 60-tooth count on the gear exactly matched the number of index holes on the main shaft gear aiding in the process..
The cost of the lathe plus shipping was less that the price of a new awning. The first of many repairs around the house that would not have been possible without the lathe.
Adam and joe have a great unofficial partnership, I fully belive between the two of them that could fix anything that comes into their shops. Keep up that relationship!
Adam, you've turned your lathe into a shaper!
I too had a One Stop Shop. Before I opened up my shop, I was a welder, a machinist and a machine shop repairman. I never refused a job. I had 1 rule.
Clean your parts before you bring them to me.
Just watched this video, and I can totally relate to a one stop shop. I am 70 years old, got a wed/fab/machine shop in the country. Seems like people from all surrounding counties come here to get things repaired. They have learned to call, bring it, leave it, till I call. Most of them have learned, that if it is fixable, I will and they leave me alone to do that. Really like watching your videos. Im from Mt. Sterling Ky. Had welding company, Dale Welding Works LLC, until I lost my son 4 years ago, sold my trucks and stay in the shop now. If I was closer to Florida, I would visit. You and I could have long conversations.
I know we have seen it before, but watching you handle a four jaw is like listening to a virtuoso play Mozart. I can see it again and again and never tire of it.
I study mechanical engineering and your content is almost therapeutic to me
Nice to see they wiped it down before they dropped it off
Never imagined using a lathe turned off as a human-powered "shaper" - how cool!
Please keep videos like these coming. They (and not the gearhead/product placement/unboxing content) are what attracted me to your channel.
Great video, Theres something about machining brass or bronze that so satisfying.
You are spoiling us with all the videos. Thoroughly enjoying all the variety.
I think I was a crow in my prior life, I love the shiny bobbles when the machining is done. That bronze is really something to see all spiffed up.
Me too. Brass, bronze, I like the chips as they come off with some nice light shining on it -- sparkly!
Nice of the customer's maintenence staff to leave the cleaning to you.
I might tick some people off but damn it folks clean your parts that you bring to guys like Adam to be repaired. They don't need to contend with your dirt before they can start the repair process. Yes I know it takes time, but would you rather pay machine shop rates or an employee that you are probably paying half as much or less to do the job!
I guess this customer prefers to pay machine shop rates! Bring it to my shop. We'll clean stuff all day if you want!
Adam, I learned more in this video than in the last 10. Thank you.
Always wondered how to cut the horizonal grooves on a lathe.
This video took me back about sixty-five years ago, when I was an apprentice.
Great video, instructive, informative, first-class machining techniques.
My, how the time has flown by!
That was a neat trick for making the oil grooves!
Nice trick with the step to align with bore!
Adam, that is a true tour de force of technical accuracy, patience and method. Your insights are much appreciated.
Adam, thanks for being realistic about these ops.
When I worked with gears, I was taught to never trust the bore to indicate but rather indicated the teeth with a pin that makes contact close to the diameteral pitch and indicate that in. Maybe I was doing it wrong. Love the videos and new shop progress!!!
That's pretty interesting, I could see how that could be an issue, maybe it's only an issue with cheaper made gears, it sure looked like it was running true, maybe if it had looked off he would have indicated it a different way.
I can't stop watching these. Just awesome. This some of the most rewarding and important work that a person can do.
I could watch you indicate all day long, great post!
Thanks for the video. always amazes me how customers bring such dirty stuff in for repair. imagine if it was returned the same way!
Ever since I was a kid I loved to watch welding and machining......dunno why I didn't go and apprentice somewhere. My Dad was good at both and was a farrier as well. I enjoyed every kind of welding there was but in particular I loved watching him weld with a forge. A friend of mine used to machine parts for my Husqvarna dirt bike when I could not get parts in time for a race. We traded work for work and his machining fit better than the original.......he was an Ace with his lathe. I'm an old guy now and I enjoy watching your uploads just as much.....thanks!
man that thing needed a garden hose or pressure washer first, I'd have been embarrassed sending that to any metal/machine shop like that. 😒
I'm glad to see that you took the job in spite of the part being so dirty. So many people are arrogant and mean-spirited. That expanding mandrel is really clever. Thanks much for another enjoyable and educational video.
So many people are entitled
I never thought of using a lathe in that way. Nice job Adam!
U actually make me forget how bad I hated being a machinist lol. You have a gift and make it look easy. I'm glad I have the ability and even more glad I dont have to do use it much any more. Love the vids!
It takes a true master to make something look as simple as you make this look. Thanks for sharing.
Enjoyed this, thanks Adam it's nice to see you doing jobs like this.
I have loved watching your videos, I’ve been at a machine shop for 6 months now and I’ve learned so much between your videos and my boss
I watched this repair series out of order, so I got to see the issues Adam had with fitting the repaired bull gear to the new shaft before I watched this video. I enjoyed participating in the "better methods" discussion after the final video. All of this is very interesting to me Adam had challenges and methods to address them from the beginning of the repair. Adam may have been more successful employing different methods, but he knows his shop limitations and assets well. He has done similar successful approaches and that likely affected his approach on this repair. I spent a career doing repair work. I didn't have a CZcams community to critique my approach. I enjoy the CZcams community when we add helpful and constructive comments. I am here to learn and Adam is likely learning too.
This series is the content that brought me to the channel. I need Adam's machining skills and he remains the best instructor that I have found for this content. I never intend to grow my machining skills beyond repair work. I worked maintenance in a high production shop for my career. I have had my fill of the high production environment. My hobby life is having the capacity to make and do what I need and want and to learn and refine skills that I lack. I learned a lot of skill practices and approach from this repair job. I will employ them when need arises.
I especially liked Adam's approach to the grease groove issue. I think of this as single point broaching or planing on the lathe. I employed a similar technique on the Bridgeport when I needed a square through hole on part that I was fabricating. I had no broaching capacity. I made a crude single point tool from a broken carbide end mill. I used the quill stroke to open the round starter drilled hole and to square the corners. Adam's skill and methods refinement outclassed my crude setup, but my method met my requirements. I like Adam's detailed explanation that matches well with his video skill. I think that I would have pressed the bushing into the trued gear bore and finished the bore to size on the Monarch, and then completed the grease grooves in that Monarch setup. I don't yet have the luxury of multiple capable lathes and I don't have a set of expanding mandrels. My methods reflect my shop limitations and my experience. Kudos to Adam and to any of us in the community who can expand my learning and skill.
Keep up the good work and videos Adam. =) God Bless.
Proper bit of machine shop work there Adam, thanks very much
Adam always learn by watching and listening to you. You do beautiful work. Thanks for sharing.
Clean up is the worst part good job thanks for sharing
First time that I see some kind of “broaching” done on a lathe! Fascinating even after all these years Adam
Nice, Adam. Knowing how much you love your shapers, I was absolutely sure that I was about to see you use one on that piece of bronze - which I have never seen done before on an inside diameter like that.
Actually I never even knew a shaper existed until watching you a couple years ago.
Thanks for expanding my own accumulation of knowledge … again.
never to old to learn and pick up tips, a couple of thou off the start of the bushing to help alignment.... cheers mate
this is the kind of real world repair i like to see. we do similar stuff in our maintenance shop.
vintage abom quality engineering- really good viewing thanks Adam
thats the way i did the grease grooves for the sheaves on my Insley front shovel. i learned a lot about machining when i was rebuilding the boom on it
Really like these process oriented videos. Very educational.
So much fun to see your work. You explain the process and why so well.
It is such a pleasure to watch an artist work!
Nice to see the home shop in action, looking forward to part 2.
Great to see a machining video. Like the expanding mandrels! 👍
You are a master. Love to watch your videos and your explanation of the process.
Amazing Those views of internal grooving are priceless.Thank you.
Tool bits are the way to go with bronze and brass I was building an item today out of brass and it easy fairly easy material to work with !
That bushing looks absolutely beautiful finished like that! I love it!
Really enjoyed that one Adam. Thanks as always for sharing your skills.
Beautiful work, really enjoyed it. That brass chip spray was just mesmerising.
Smooth operator you are Adam. Visualization of experience. Well done!
Lathe - Broach! I am no machinist but I love the way a great machinist can get more out of their equipment!
Nice planning and machine work. Thanks for the share.
Great video and audio of the shaper work on the lathe. Well worth the effort.
Definitely enjoyed the video. Top notch filming.
First time I ever saw a lathe used as a shaper. Great stuff!
I love the lathe operation where it's not turning, the longitudinal oil grooves.
Great video Adam. A lot of tricks for a small job. Cool!
Outstanding lessons to be learned in this episode... Thank You Brother.
You are an amazing teacher, thanks for sharing and explaining.
We do similar bushings, different material. The OD and ID are on the lathes of course, but then we move it to a Haas UMC to do the grease grooves. Never thought of how it would be done on a manual machine. Cool stuff, thanks for sharing!
Hey Adam, I just finished watching all of your past videos. Thanks for all the great content, I have learned so much from you. It would be good to see the install of the DROs on the Victor and the Monarch, they probably would be of more use on the machine then just hanging around the shop, but I know how it is, I am just getting to projects I have been putting for years, thanks again.
This kind of work mesmerizes me! It’s fascinating to see such perfection! 👍🏼
Always a pleasure watching your skilled, dedicated and thorough work, thanks for sharing!
Greetings from Norway.
A pressure washer would have been the fastest and easiest way to clean that gear. Having a cheap electric pressure washer around to do jobs like that is well worth it, you can get a decent one for under $100.
There are a lot of customers who don't realize that most machine shops have to order material for every job. Waiting on material is a major component in the total time it takes to finish the repair.
In some places there are regulations that prevent machine shops from washing stuff like that gear outdoors.
Adam as always with your work that is a thing of beauty. Great video work as well. Best Regards to you both Sarah
That final shot of you pressing it in was very cool. Nice work.
Always love the look of property machined Bronze
Needed this exact thing done on a large drive wheel for a portable mill. NONE of my local shops were willing to do it. Spent over 600.00$ on a new drive wheel.
Great video , Always something new i learn . Helps me out when i get some of the little jobs i do . Thank You !!
Wow, had to pat myself on my back. When you explained what you had to do, what you did instantly popped into my head. Scary!
I watch a lot of your videos and this has to be the most informative and interesting ,how you work with the brass and measuring it all excellent work !Adam awesome 👍
That is some good work Adam! I really like to see those this kind of machine work.. great video..
Good work! Enjoyed watching, thanks.
That Bore cut Chip-Flow was beautiful.
"I have enjoyed following along with this one" thanks for sharing.
Excellent work as usual Adam-!
Nice job Adam always a treat to watch👊👊👍
talented machinist, talented content creator... thanks for the countless hours of entertainment
You do such great work Adam.
Lots of nice detail work.Thank you.
Awesome work, I’ve been really looking forward to this video. Definitely learned a lot of tricks that I will be trying out myself. Thank you.
That was excellent work very informative and a joy to watch. Thank you
As always another great video! Thanks Adam.
Great techniques. Good work. Linen gear bushing.
its interesting how those brass...or is it bronze....chips spray off the tool bit. And that line up step is a Great idea. I can think of 2 times that would have been handy on pulleys i had to work with. SWEET
Bronze. Probably phosphorus bronze at that (since it's a bushing). But yes, copper, bronze and brass chips break easy, and they all machine very nicely with a sharp tool.
Great job as always Adam 👍
awesome video as always, love the detailed explanation.
Love the expandable mandrel. Gotta get one. Thanks for the info on CRC. Right down the road from my work at Coca Cola Robertsdale. And as always, another flawless job. Thanks for sharing.
A nice professional job Adam!
Nice work. Great video and explanation as always.
I watch you work every single chance I get.......although I've done very little on a lathe, I could stand and observe all day. Thanks, Tom P.S. I is SO RELAXING!!
I've learned so much from you, Adam. Thank you!
