Its just so positive to hear an American say "great stuff" about things made outside USA. Too many American youtubers keep repeating "American made", as if that would be a quality by itself.
I've spent over 40 years in the machine industry (as I've said before). Eyes and ears and hands are everything. Along with a brain that can process it all at once! And having "the touch" (as I'm told I do) is something you can't explain! 😁

Adam probably asks himself: ' On a scale of 1 to 10, how good will this job be for the channel' before he decides to take it on or not. I wonder if he also has a scale for ' Could this be the customer from hell?', though I suppose if you were a Patreon, it might help.
It was beautiful work that would not be affordable to have done without it being good for RUclips. The bushing work by itself MAYBE if the rest of the machine was a peach, but the spray weld repair AND the bushing? You'd be wondering why you aren't replacing the machine. Or ordering/having made a new spindle shaft. As he said at the end "A good repair and provide some content to the channel." Nice to see frankly. Even if the customer paid pretty solidly for the work, still worth every penny.
Customer probably paid for this job. I actually had Adam look at a part for a flame spray repair and received a quote for it, wasn't expecting a free lunch

Hi Adam, good of you to help this man get his lathe back up and running. It does my heart good to see Your Grandad & Dad in the closing credits. My Grandad was a butcher and Jack of all trades, Dad was a Machinest for a major Company who made seats for Willys, Ford, & Chrysler back in the Day.
As always, the fit and finish of Adam's jobs are superb. The miking of the bored-out spindle ID, fore and aft, to the exact thousandth; turning the OD of the bronze bushing to exactly 2 thousandths over; the carefully chamfered edges, along with the tip about easing the bushing's entry surface for proper fit; these are the work of a master machinist. I enjoy the CNC machining videos, but these manual projects really put Adam's wonderful skills on display. Bravo.
Man, you are a master machinist for real! It's so beautiful and so enjoyable watching a master at his work with years and years of experience. It's such a joy to hear you work that literally the music just cues my brain to be at peace knowing I get to watch stuff like this!
I like that you teleported to the old shop to do parts of the job. You need to hire This Old Tony to fix you a crazy video transition for when that happens haha
Noooo! There's too many loud and annoying transitions on RUclips, and more and more everyday. You only add these noxious transitions when you don't have any good content. Abom does it properly.
One of the _many_ reasons I love this channel, is the _last_ image. Adam has the knowledge of his father and his grandfather. Adam is passing on to the world machinist knowledge that dates back to World War II, 80 years ago. Adam just peppers his video with nuggets of pure gold information that is _essential_ to producing precision parts.
Abom - For the chip deflector you might want to consider taking a leaf from Sandblaster supplies? They use a very thin plastic sheet expecting it to be sacrificial - you could use them with a few bulldog paperclips to hold them to the deflector - Means you have a consumable that you can replace whenever you want to refresh your vision
What would speak against using a piece of actual glass? I know, if something goes wrong you get a lot of shards, but it won't scratch much. Maybe this safety glass that doesn't break into sharp shards but tiny cubelike pieces? Or another idea: put a screen protector for tablets on that plastic, so you can easily swap it out if needed. Those are pretty scratch resistant too I think, might be worth a shot, there's propably one out there in the right size.
@@CatNolara The issue with "Safety glass" is that it's under strain - due to that 1 sharp chip impact can lead to it actually shattering easier in some cases than normal glass that would just chip and be otherwise fine - Plastics on the other hand are maleable and give when impacted far better than glass Tablet screen protector is essentially the same idea as my suggestion - the reason I'd bias towards the sand blaster supply is you can talk to a supplier and get a hundred or so cut for pennies on the dollar to whatever size you want
@@RyanDoesAll Personal decision on that point - As mentioned you should be able to get them for a few cents per sheet - They're a weekly consumable for a sandblaster that is there to protect the actual glass behind it
Very similar to my Jet 1024. I had exactly the same problem, and have learned that it's common in this class of Taiwan lathes. I did pretty much the same repair. I didn't flame spray the spindle (didn't even know about it) but just polished it as best I could. Then I bored out the pulley cone, pressed in a long oilite bushing (oilite seemed like a good idea, though two plain bronze bushings with an oil reservoir between may have been as good or better) and bored the bushing to fit. I made an oil groove lined up with the oil port, just short of the ends of the bushing. It's a straight groove, not ideal, but I didn't know how to do a spiral groove. That largely fixed the problem, but I didn't give it enough clearance, and it would still seize up after 20 minutes in back gear. After 30 years of tolerating it, and just before retiring and losing access to a lathe at work, I bored another thousandth out of the bushing, and now it never seizes. I don't remember how much clearance I ultimately settled on, but it's probably 2 or 3 thou. I hope you left adequate clearance, .0008 doesn't leave much room for an oil film, or allow for spindle expansion. These spindles get pretty warm, I believe due to bearing seal friction. You did an excellent job, but I'm afraid you're not done. As for your chip shield, replacing the "window" periodically should be cheap. I got a couple of pieces of Makrolon out of the remnant bin at Tap Plastics, and they didn't even charge me.
His target was a half thou. Not sure if he explained that, as I might have missed it. Googling the clearance for engine main bearings gives a general rule of one thou per inch journal diameter, so for this case might? imply 2 thou.
@@richardjones-sl2zd Plus, the temperature inside an engine, while fairly high, is probably fairly uniform. The problem I found is that the spindle heats up more, and quicker than the pulley cone. Whatever oil gap you have when cold shrinks as the spindle heats up. I had to take two runs at the problem, and wound up with a somewhat loose cold clearance to avoid seizing when hot.
It's great to see a real machinist at work with a manual lathe. You are very proud of your work. It's just fantastic to watch you work. Precision is your password.
Adam always love watching your program. As a retired long time tool and die maker I am surprised you wear a watch while on the lathe. Was always warned watches and rings were a no no around machinery. Safety is number ONE. I like the Flame Spray Build up on the spindle body. You are always coming up with great content! Thank you
Adam your camera work is really perfect because you care for detail. and you explain in best way and your teachings are top notch. I was service tech all my working life. I was never able to do the things you do other than turning brake drums and rotors. thanks to you and Abby for your quality work. hope you have a wonderful time in your new shop.
I love to watch the different machinist on youtube and they are all different, watching the Pakistanian machinist and ones that are in the mining industry, they all have a different approach to how they attack things. Adam is very particular and pays attention to details, he is an excellent machinist old school.
I have said it before and I will say it again. These are by far the most educational RUclips videos on the planet Yes Adam, you're that good. Thank you from the bottom of my chip pan
What a coincidence! I have been building bronze (932) bushings for John Deere sprayer booms. For turning the ID of the bushing I put some 2" blue painters tape sticking out 1.75" past the end of the bushing stock. This deflects the chips toward the back of the lathe rather than spraying out radially. Since I turn the bushing ID first, I stole an idea from youtuber Joe Pie and made a mandrel with a rubber packing gland, so I can turn the OD to size. I cut a notch in an old plastic protective lens from a welding helmet that just fits over the cutting tool in a quick change tool post to deflect the chips downward away from me. I appreciate your comments on using manual lathes in a job shop setting. That is what I do 99% of the time. My lathe is a Fitchburg made in 1898 with a National 4 jaw chuck.
Beautiful fitting, never get tired of your videos, going right back to your old shop improvements and purchasing of machinery.. miss the shaper videos.. but can understand, you must be busy Man ..
I really appreciate the fact that you did not flip the pulley around to work the backside. That was some good content - showcasing the complexity of working in opposite directions from inside the chuck!
Another great video as always... Keep on making more. A poster mentioned this repair was a lot of time and effort to do for someone you never met. Well, I think I could speak for most machinist's is that your work is all about the "exactness" of the project that keeps you going. Heck, maybe 5, 6-7 years ago I watched you make a hinged support for something bolted to a machine and everything had a chamfer and the pin to hinge was a couple thousands. Was definitely overkill, but I understood the passion of "exactness" Subscribed & liked from then.
I`ve god a Myford Super 7 and got no clue how to use it but im learning so much by watching your videos. thank you so much for taking the time and effort to show this. cheers
I look forward to and watch all of your videos....! THIS was one of the better one's. An hour of simple but accurate machining, Keep up the good work. Camera work was great also....!
When you reversed your chuck jaws, it looked like you started some of the screws with the impact wrench. As a mechanic for 35 yrs, who occasionally plays like a machinist, I can tell you this is a habit you need to break. That's the best way I know to crossthread something.
It is so good to see some excellent content again instead of advertisements of equipment none of use are likely to ever see, never mind use. I particuallyly liked the section showing the level of [pressure you use between the micrometre and bore gauge.
Mr Booth: Thank you. I am a geek. a retired computer geek. I know you are trying to learn CNC. I used to do control code for similar devices. I always admired guys who could build things with their hands. Always wanted to do as you and folks like you do. I retired about 10 years ago and 6 months later was totally obsolete. You on the other hand, who are a third generation machinist who learned from an early age KNOWS a TRADE.. Been watching your videos for over a decade. Your small tips; the things you know, help ALL of us. Adam, I have learned so much. I have a small hobby lathe and A drill-mill: Grizzly G0602 and a PM 727. What we Computer Jocks do is NOTHING like what you masters do. Please know this.: I salute you sir as a Master! btw cool vid..
Been over 5 year of watching your videos and your video quality has always steadily improved but your quality and care you put into your work is as impressive as always
Tip I learned from a coworker about chip control when machining bronze. Turn your cutter upside down and run in reverse, it will throw all the chips into the pan for you with less spread. Has worked pretty well for me, hope it helps.
Adam, I hope you know how much we enjoy and profit from these videos. Seeing those bushings in there with the oil grooves and beautiful surface finish is a real joy. Thanks so much for sharing your knowledge and expertise with us. Best wishes for a good week ahead an as always, greetings from Germany.
Adam, thank you for the great project video. Your passion and desire to teach others is clearly evident in this video. I learned a lot about indicating and set ups and so much more. You are a great teacher and a master machinist. Thank you very much for your efforts
I am not a machinist but work in gear mfg. i love the look of braze on iron. Your videos are amazing and I’m glad you show the setbacks. I’m not as calm as you!
Great video, always producing good content. For people with this stile of back gear the reason it galls up is, because people forget to lubricate the center. The reason for the center clearance is for an oil/grease reservoir. In the pully section, the center belt groove has a set screw, that set screw is actually a plug to add oil/grease for when using the back gear.
To keep your chip shield from getting etched, an easy solution would be to buy some gorilla glass screen protectors for a tablet and use them on both sides. As they eventually get pitted, they can easily be replaced.
Adam, thank you for the wonderful videos. My machining skills are just above handyman level and I do some prototype work and a few simple repairs. I find your videos both entertaining and educational. Keep 'em coming, dude.
The plastic guard you can fix it by buffing it up it should remove a lot of the scratches from the burrs. Very informative and very knowledgeable mechanist 👌
Watching you finish that second bushing without removing the work was one of the coolest things I've seen on this channel. To go around the back of the work, inside the chuck, and face a part moving in the opposite direction - this is the type of ingenious mastery that I've come to expect from this channel. Top that off with hand shaping the axial grooves and hand removing the chatter from the oil groove, what an awesome project. Thanks for another amazing learning experience!
Yep, this is the kind of videos that I love watching because for manual machining it’s educational. I still enjoy the CNC stuff as well but can’t see me ever owning CNC machines at my age - so it’s not as personally relevant to me.
I really enjoy both types of videos, I have manual machines at home but run CNC all day at work. I like to stay fresh with the manual techniques since I don't do it as often. Great stuff.
Very nice Lathe, and nice tool holder, which it's easy to bring several tools on Center, & use them when needs, in such an easy drop in and go on working, I use to work on an Engine Lathe & a Turret Production lathe with such a facilities with citting tool holder, much easier than the traditional tool holder, were you must use a metal piece to rise the tool up to the center. Machienes are getting more sofisticated and easier to use And saving times as well, I like your shop, you are a very excellent narator on the issues, keep it up and I will continue to watch. High thumb up.
A one, yes I did enjoy watching you work your magic. When skill and knowledge comes together results are usually great. Thanks for another learning experience.

@@RyanDoesAll Personal decision on that point - As mentioned you should be able to get them for a few cents per sheet - They're a weekly consumable for a sandblaster that is there to protect the actual glass behind it
Very similar to my Jet 1024. I had exactly the same problem, and have learned that it's common in this class of Taiwan lathes. I did pretty much the same repair. I didn't flame spray the spindle (didn't even know about it) but just polished it as best I could. Then I bored out the pulley cone, pressed in a long oilite bushing (oilite seemed like a good idea, though two plain bronze bushings with an oil reservoir between may have been as good or better) and bored the bushing to fit. I made an oil groove lined up with the oil port, just short of the ends of the bushing. It's a straight groove, not ideal, but I didn't know how to do a spiral groove. That largely fixed the problem, but I didn't give it enough clearance, and it would still seize up after 20 minutes in back gear. After 30 years of tolerating it, and just before retiring and losing access to a lathe at work, I bored another thousandth out of the bushing, and now it never seizes. I don't remember how much clearance I ultimately settled on, but it's probably 2 or 3 thou. I hope you left adequate clearance, .0008 doesn't leave much room for an oil film, or allow for spindle expansion. These spindles get pretty warm, I believe due to bearing seal friction. You did an excellent job, but I'm afraid you're not done.
As for your chip shield, replacing the "window" periodically should be cheap. I got a couple of pieces of Makrolon out of the remnant bin at Tap Plastics, and they didn't even charge me.
His target was a half thou. Not sure if he explained that, as I might have missed it. Googling the clearance for engine main bearings gives a general rule of one thou per inch journal diameter, so for this case might? imply 2 thou.
@@richardjones-sl2zd Plus, the temperature inside an engine, while fairly high, is probably fairly uniform. The problem I found is that the spindle heats up more, and quicker than the pulley cone. Whatever oil gap you have when cold shrinks as the spindle heats up. I had to take two runs at the problem, and wound up with a somewhat loose cold clearance to avoid seizing when hot.
Great thing to have after dinner, playing an Abom79 video in 4K! perfect thing to relax to!
Bronze inserts could not have been turned down more perfectly. Awesome job! Thanks for sharing!
Thanks for sharing the restoration of Steven’s lathe parts. The shop talks and tips is the stuff of legend.
It's great to see you slinging chips in the new shop. That PM lathe is sweet.
Polish machinery and tools enjoy an excellent reputation. Glad you mentioned that. It was enjoyable seeing this neat job. Thanks for sharing it!
It's great to see a real machinist at work with a manual lathe. You are very proud of your work. It's just fantastic to watch you work. Precision is your password.
Excellent workmanship as always and your instructions are very, very good.
Adam always love watching your program. As a retired long time tool and die maker I am surprised you wear a watch while on the lathe.
Was always warned watches and rings were a no no around machinery. Safety is number ONE.
I like the Flame Spray Build up on the spindle body. You are always coming up with great content!
Thank you
I like watching you do the manual machines for the 1 off's jobs.
Very good series of the repair for Steve.
Adam your camera work is really perfect because you care for detail. and you explain in best way and your teachings are top notch. I was service tech all my working life. I was never able to do the things you do other than turning brake drums and rotors. thanks to you and Abby for your quality work. hope you have a wonderful time in your new shop.
I love to watch the different machinist on youtube and they are all different, watching the Pakistanian machinist and ones that are in the mining industry, they all have a different approach to how they attack things. Adam is very particular and pays attention to details, he is an excellent machinist old school.
Adam, this is certainly your finest video yet.
Thank you,
Capt. Art
I have said it before and I will say it again. These are by far the most educational RUclips videos on the planet Yes Adam, you're that good. Thank you from the bottom of my chip pan
What a coincidence! I have been building bronze (932) bushings for John Deere sprayer booms. For turning the ID of the bushing I put some 2" blue painters tape sticking out 1.75" past the end of the bushing stock. This deflects the chips toward the back of the lathe rather than spraying out radially.
Since I turn the bushing ID first, I stole an idea from youtuber Joe Pie and made a mandrel with a rubber packing gland, so I can turn the OD to size. I cut a notch in an old plastic protective lens from a welding helmet that just fits over the cutting tool in a quick change tool post to deflect the chips downward away from me.
I appreciate your comments on using manual lathes in a job shop setting. That is what I do 99% of the time. My lathe is a Fitchburg made in 1898 with a National 4 jaw chuck.
Beautiful fitting, never get tired of your videos, going right back to your old shop improvements and purchasing of machinery.. miss the shaper videos.. but can understand, you must be busy Man ..
Brings back old memories , I’m retired machinist enjoyed watching
Not a machinist here, but I enjoy watching a master … thanks!!!
I really appreciate the fact that you did not flip the pulley around to work the backside. That was some good content - showcasing the complexity of working in opposite directions from inside the chuck!
Enjoyed the closeups of reading the snap gauge.
Another great video as always... Keep on making more. A poster mentioned this repair was a lot of time and effort to do for someone you never met. Well, I think I could speak for most machinist's is that your work is all about the "exactness" of the project that keeps you going. Heck, maybe 5, 6-7 years ago I watched you make a hinged support for something bolted to a machine and everything had a chamfer and the pin to hinge was a couple thousands. Was definitely overkill, but I understood the passion of "exactness" Subscribed & liked from then.
The Chinese Td-4 39 inch 12 inch swing belt drive 1.5 HP lathe was sold under many Brands , Mine is Smitty BZ 239. Excellent repair !
I`ve god a Myford Super 7 and got no clue how to use it but im learning so much by watching your videos. thank you so much for taking the time and effort to show this. cheers
I look forward to and watch all of your videos....! THIS was one of the better one's. An hour of simple but accurate machining, Keep up the good work. Camera work was great also....!
Very entertaining episode Adam, thanks for the thorough explanations.
I’m always impressed that Adam, a large man with large hands, has such a delicate and deft touch when using telescoping gauges and micrometers.
The pm lathe looks pretty nice. I have dealt with Matt from Precision Matthews. He's a good guy to deal with. They have good customer service.
When you reversed your chuck jaws, it looked like you started some of the screws with the impact wrench. As a mechanic for 35 yrs, who occasionally plays like a machinist, I can tell you this is a habit you need to break. That's the best way I know to crossthread something.
It is so good to see some excellent content again instead of advertisements of equipment none of use are likely to ever see, never mind use. I particuallyly liked the section showing the level of [pressure you use between the micrometre and bore gauge.
Mr Booth: Thank you. I am a geek. a retired computer geek. I know you are trying to learn CNC. I used to do control code for similar devices. I always admired guys who could build things with their hands. Always wanted to do as you and folks like you do. I retired about 10 years ago and 6 months later was totally obsolete. You on the other hand, who are a third generation machinist who learned from an early age KNOWS a TRADE.. Been watching your videos for over a decade. Your small tips; the things you know, help ALL of us. Adam, I have learned so much. I have a small hobby lathe and A drill-mill: Grizzly G0602 and a PM 727. What we Computer Jocks do is NOTHING like what you masters do. Please know this.: I salute you sir as a Master! btw cool vid..
Been over 5 year of watching your videos and your video quality has always steadily improved but your quality and care you put into your work is as impressive as always
Great job and a very good upgrade on the machine!!
Thank you as always.
Great video Adam. And a great result, old mate will be happy with that. It's good to keep older machinery running.
Tip I learned from a coworker about chip control when machining bronze. Turn your cutter upside down and run in reverse, it will throw all the chips into the pan for you with less spread. Has worked pretty well for me, hope it helps.
I like how you teach Abom. Your a very good machinist. Thank you for your videos.
I'm impressed. That was a ton of fun. Thanks for sharing the project. Much appreciated.
Adam, I hope you know how much we enjoy and profit from these videos. Seeing those bushings in there with the oil grooves and beautiful surface finish is a real joy. Thanks so much for sharing your knowledge and expertise with us. Best wishes for a good week ahead an as always, greetings from Germany.
Adam, thank you for the great project video. Your passion and desire to teach others is clearly evident in this video. I learned a lot about indicating and set ups and so much more. You are a great teacher and a master machinist. Thank you very much for your efforts
I am not a machinist but work in gear mfg. i love the look of braze on iron. Your videos are amazing and I’m glad you show the setbacks. I’m not as calm as you!
Your work is so enjoyable
An absolute pleasure to be able watch you do all this excellent machining,
I learn so much,
God bless you all
Watching the master do job work are my favorite Abom videos.
Awesome work, Adam! Very nice set ups and procedures. Your customer will be extremely happy. I’m sure.
Great video, always producing good content. For people with this stile of back gear the reason it galls up is, because people forget to lubricate the center. The reason for the center clearance is for an oil/grease reservoir. In the pully section, the center belt groove has a set screw, that set screw is actually a plug to add oil/grease for when using the back gear.
Finally, a good educational video without too much advertising, see that's why I subscribe to ABOM79.
Keep up the good work Adam. 👍
These special one-off repairs are amazing. Really shows the art of the craft.
Real talent and skill - and there is never a substitute for experience !!!!!
thank for the new video enjoy and looking forward to this everyweek
Thank you Adam for sharing! Your skill and knowledge is excellent and you explain things in such a concise and simple way. Really appreciate it!
Excellent tutorial and it is free valuable knowledge compiled over 3 generations.
Love to watch you work on the manual machines
Very instructive Adam
Thanks
Frank
To keep your chip shield from getting etched, an easy solution would be to buy some gorilla glass screen protectors for a tablet and use them on both sides. As they eventually get pitted, they can easily be replaced.
Hey Adam,
Steven is not going to believe the difference this repair is going to make/have on his machine. Awesome job!
Thanks for that brilliant video Abom; craftsmanship on the lathe and very clear camerawork as always
Very precise work from a very experienced engineer 👍👍
I really enjoy seeing you put to use all the tricks of the trade you have picked up. Keep the videos coming, I'll keep watching!
Adam, thank you for the wonderful videos. My machining skills are just above handyman level and I do some prototype work and a few simple repairs. I find your videos both entertaining and educational. Keep 'em coming, dude.
Really enjoyed watching this repair, I’ve learned a lot from you over time , Thanks
Amazing. Your skills on the lathe are as good as a surgeon.
The plastic guard you can fix it by buffing it up it should remove a lot of the scratches from the burrs. Very informative and very knowledgeable mechanist 👌
You're a great teacher Adam. Thank you for showing all the little details of setup, measuring, tool bits, etc. It's all great content!
Loved to see this lovely machinery, tools and skill in action. That was a beautiful job. I really enjoyed this. Thank you.
Watching you finish that second bushing without removing the work was one of the coolest things I've seen on this channel. To go around the back of the work, inside the chuck, and face a part moving in the opposite direction - this is the type of ingenious mastery that I've come to expect from this channel. Top that off with hand shaping the axial grooves and hand removing the chatter from the oil groove, what an awesome project. Thanks for another amazing learning experience!
Yep, this is the kind of videos that I love watching because for manual machining it’s educational.
I still enjoy the CNC stuff as well but can’t see me ever owning CNC machines at my age - so it’s not as personally relevant to me.
I really enjoy both types of videos, I have manual machines at home but run CNC all day at work. I like to stay fresh with the manual techniques since I don't do it as often. Great stuff.
Very nice Lathe, and nice tool holder, which it's easy to bring several tools on Center, & use them when needs, in such an easy drop in and go on working, I use to work on an Engine Lathe & a Turret Production lathe with such a facilities with citting tool holder, much easier than the traditional tool holder, were you must use a metal piece to rise the tool up to the center. Machienes are getting more sofisticated and easier to use And saving times as well, I like your shop, you are a very excellent narator on the issues, keep it up and I will continue to watch. High thumb up.
Excellent illustration of skill, care and education. Well done.
If you use a polarizing filter on your camera you should be able to reduce if not eliminate the reflections when using the plastic defector sheet.
Excellent machining and filming. Thanks
34:22 - loosen your lowest; tighten your highest.... 👍🏼👍🏼 I’ve run a le blond in years past ... nice looking shop...✌🏼
WOW! That’s some fancy, intricate machining you did. So impressed.
A one, yes I did enjoy watching you work your magic. When skill and knowledge comes together results are usually great. Thanks for another learning experience.
Always love the long format videos Adam, even though I know it kills the algorithm. Thanks, always appreciate your productions
Hey Adam, been a subscriber for about 4 years now love the New CNC and New Shop content, but was great to see an in depth hand machining repair like this. Love the content
With both types of machines available to do the work, it will offer the best option to get the work done.
Superb job, very fine result, really good to this kind of manual machining again.
I throughly enjoyed this video. Nice job Adam.
I love watching your small but technical jobs so interesting
I enjoyed this very much. I like the manual lathe stuff.
Excellent rebuild, tips and techniques.
