Keith, thank you so much for these three videos. Very neat line boring bar set up. Yea, interrupted cut sure is rough on the cutting tool. It was a pleasure to watch an old school craftsman at work. I myself have an old 1942(one year older than me), 10 in. Atlas lathe that I fight with. I'm an old school mechanic, who can machine things, but I'm NOT a machinist. I really admire you workmanship.
What a fantastic job, you are a truly skilled and knowledgable engineer, you could work anywhere and for anyone. I thoroughly enjoyed this video, thank you so much for all your hard work in making this video and presenting it on you tube. All the best from Andy in Bonny Scotland.
it can be a small world, unless you are the one that has to clean it. GREAT series !
being a land speed and drag racer this was good stuff. the making of tools is one of the reasons I first loved about your show. best video in long time for me as I love cars. I bet big turbo caused the need for bigger caps. love it. thanks for sharing.
I really liked this series. I don't do machine work but I did used to build my own engines. This was very interesting to watch and to be able to see the details of how it was done
That was an awesome vid through and through . At the beginning I have to say I wondered how in the world you could do that on a lathe . Low and behold you showed us how . Thumbs up !!
Can't decide what I admire more, your skill or your attitude.
Both are over and above normal tolerances. I have been following Keith's work via his video presentations for some time, quality of his work, foreplanning and attention to detail has always been at the highest level. Having myself been involved in construction of 2, 3 and 4 wheeled competition vehicles, engines and powertrains at some length, this particular series has been of a special interest to me. Cheers from Indonesia.
This is top shelf. You're at the top of your game, Fenner.
This series is one of the reasons i watch your channel Keith. Very few people will ever attempt this type of job without the benefit of a dedicated line boring rig, but you show us how to do so in an offset lathe setup. Incredible! I've been machining for 36+ years as a student/hobbyist/mechanical engineer (very hands ON) and its videos like this that have made me much better than i was before i discovered youtube or Keith Fenner. Thanks man. Keep it up.
I got addicted to your channel a few months ago. Every “episode” the addiction is ever more pleasant and deeper. Learning from you is helpful in every facet of life. Thank you.
Keith: As always, another outstanding video (in content, explanation, process, & editing)! You had the best line boring series on the net previously, & this may top that. While there may have been alternate ways (even faster/easier) to accomplish this job, your "Getter Done" attitude using the tools at your disposal is what makes this so great; and frankly what machining is ALL about. Really appreciate you sharing your knowledge. I've NEVER seen/heard the quality explanation of toolbit location above/on/below centerline for boring; Thanks! Can't wait to see what's next.

I forgot to mention in my initial comment.....At the end you mentioned your wood stove (being redone) and heat treating; I'm very excited to see what you have in store for us relative to that subject!
Hi Keith, I love you never speed up your videos. Pure craftmanship. Happy New Year.
My experience has agreed with yours for above central line cut. Interesting how old school high-speed steel seems too be the best fall back. Great video Keith!
keith i would just like to say love your videos been watching for some time i don't do any type of this work but its amazing the type of things you can do with the machines you got , i have alot of respect for you an the amount of knowledge you have an share with us keep up the amazing work .
These 3 videos were very informative. Your explanation of the offsetting of the tool is worth a million to machinists worldwide.
Hi Keith, I was wondering how you were going to measure the bore, now I see how your going to do it. Going back to watch the rest of the video.
I really liked what you said at the end, about sharing challenging ways of doing jobs, (out of the box ways), I've always said thank you for taking the time to show the behind the scenes of the jigs and toolings being made to do a job professionally, and this series confirms the same, I would like to say thank you again, for giving the details of the complete job, not just the job itself, but the workings behind it, that makes the job work out perfectly, your patience and accuracy is top level, for inspiration to me on doing any job, machining and woodworking, to that kind of detail attention, your a great teacher on professional workmanship.
Hey Keith! Sweet videography, not to mention the creative use of the machinery at hand! Bravo ... :-)
Thank you Keith. I am not a machinist but, watching your channel helps me to better understand the work it takes to do a job right. Well done Keith. I love watching this channel it keeps my mind sharp. Very good job on the close up footage and lighting. Never to old to learn something new.
Loved the explanation of the offset toolbit, really got me to understand the mechanics of it. This was a really interesting series with many different solutions to different parts of the setup.
Now I am impressed. This isn’t just seeing machining done, this is showing you how that tough jobs get done. Thank you for the effort here, you should be as proud as I am impressed.
Nicely done Keith. Love the view from the borescope!
Wow, never thought about a setup like that, makes this seem very possible for a skilled guy in a home shop with lots of time to fiddle could get this done with a *little know how to be dangerous.. Nice work!
I've been in the business for 40 years. You did one hell of a job. Congratulations.
Fantastic set of videos Keith. I love the fact that you point out this is not your bread and butter work, there will be specialist facilities that could no doubt do this job in a fraction of the time. That's not the point though, what you demonstrate yet again is that by thinking a job through there will usually be a way to get even the most challenging task done. Thank you, you are a proper inspiration.
Keith the quality of work - and video production in this one is really up there. Thank you for taking the time to get us all in there as tight as possible to see even better than we probably could if we were standing right next to you. I personally learned quite a bit in this series (despite seeing all your other videos). Can't wait to see the heat treat
Another great Video! Rely love the shots of the bore cam, makes for a good view of the bit cutting up close. Thank You.
Hi Keith, your attention to detail in both your machining process and your videography is phenomenal and increases our viewing pleasure exponentially! I really appreciate the amount of work you have obviously put in and if there was a TH-cam Oscars, you certainly have my vote! 👍
You mentioned out of the box thinking on this job Keith ... I think you excelled yourself this time . You're a clever guy and I could listen to you explaining what and how all day long and I thank you for that .😊
Thank you for producing and showing us such an innovative and effective method for line boring.
I honestly wouldn't have considered this before, but seeing what you did and HOW you did it, I am majorly impressed and feel I have learned something from a master here!
These are some very well made videos. Very relaxing too. High level work.
Kieth you are a great teacher and have taught me to slow down and think things thru !! Thank you for all the time it takes to make the vids !!
Thank you Keith! I have been an automotive novice machinist since high school and spent a tour on a Navy tin can as a machinist mate. Your personal satisfaction with this series shows and it's great to watch the process of figuring out the obstacles and other fine points prior to putting cutting edge to metal. If I ever get to the east coast I'd like to look you up. Mean time, keep up the good work.
Keith, I love this sort of video, watching you think outside the box and all the processes to do the job is just fascinating. Thanks for sharing.
Not a machinist but I certainly enjoy your videos. Amazed at how you get these efforts come together
Amazing work. What a great way to get every penny and capability out of that machine. You are the only one I have seen doing line boring in this fashion, I figured you would be limited to what you can do by the centerline of the spindle....but you just blew my mind. I would love to try this sometime.
Thnx for nice very close up camera views. Learned a ton.
Great job Keith fantastic trade skills using the available machinery to get the job done ... passion shown and I could tell you enjoyed the project enormously old school stuff. Horizontal borer easier not as much fun!
P.S. I still use quality H.S.S regularly especially for screw cutting 45 years in the trade still love it like the day I started. Thank you Dibbo
Hi Mr. Keith,
I am very happy to see your video, because now I have got a very real proof ... because some time ago I thought that in the lathe can do various kinds of jobs including line boring work,
but some people who don't believe, don't even agree with my argument,
when I see your video, and finally I really find proof, and I will show those who have denied my opinion,
so far I have only thought about and explained it in theory, but no one believes ...
thank you sir keith, you are very extraordinary
Wow!!! Seriously the best machining camera shot ever!!
I know right, Unbelievable precision AND found a way to showcase it perfectly!! well done, Keith!
Really enjoyed this series, just binge watched all three. A big "a-ha" moment when I saw the set up in the beginning of pt. 2. Thanks for a great set of vids!
That's awesome work Keith. Amazed that you could pull that off without hitting the bottom journals. Bravo!!!
Attitude, attitude is the skill in this video that shines the strongest.
I absolutely love seeing u do a video like this Keith. Thank u
Kenneth Makes some nice Billet Main caps and you do a great job Line boring them .Love these in depth video series. Thanks Keith
Magical and well executed project, thank you. Many of us are working or have worked on machines and you have shown here how to think "out of the box" to resolve a tough challenge.
Time, a lot of time spent on the job. I respect you. Cheers from Poland
Nice set up Keith and great camera work, thanks for the for showing us some great machining work.
Excellent video series Mr. Keith! Thank you.
Great video Keith, I felt like I was right there with you. Thanks
Brilliant! That setup was just beautiful. It did the job and that's what counts! Thanks for the videos.
Absolutely awesome video, Keith. One of your best ever.
Keith , Absolutely loved this video ! always enjoy when you take on the challenge and share it with us, your viewers !!
Your a true machinist buddy I learn something everyone I watch one of your videos👍
thanks for taking the time and effort to actually do the job, video it and bring it out for our entertainment and education
Keith, thanks for another great video and answering my question about your tool setting.
Facinating and enlightening series of videos, thank you.
This is off topic but I wanted to post on a recent video in the hope you'll see it. I'm an industrial mechanic. We have a mixer that turns 3600 RPM and was vibrating about 5 on the Richter scale. The "cure" was to loosen the bolts on the top 4 bolt self aligning bearing, allowing it to gyrate like a drug crazed go go dancer. I cut a new piece of 2" shafting (50" long) and put it between centers. I don't have rollers and no time to make them. >021" of runout. I used your technique to straighten it. Got it within .003" in the time I had. I installed it yesterday and the mixer is now a smooth operator. Thanks, Keith.
Really enjoyed this project. Thanks Keith.
Fantastic video Keith. So much skill and knowledge you have. Having watched this video I realize I have only scratched the surface in my machining journey. So much to learn and so many different aspects.
In all jobs I got along my life, I needed that challenge of doing things for the first time, this keeps up alive and interested...
This was vrey well done and great filming, really like when you show those projects that require some thinking....
Right about HSS saving our butt way more than once... The miracle tool...!!!
ATB, Pierre
Once again I'm impressed.
Also the stuff kenax makes is amazing, he takes billet goodies to a whole new level. Thanks again for sharing .
What a terrific summary....such a good teacher.....
Outstanding work! You are truly a " Master Machinist " thank you for sharing.
"Favorite 70's tool" Those were the days my friend
We thought they'd never end
Mary Hopkin would be pleased that you remembered her
Thank you! jonka
Boring that not boring at all! Great out of the box challenge. Kudos on a great result!
Good am Keith, thoroughly enjoyed your latest 3 part video. As a retired diemaker I appreciate your creativity and attention to detail in all of your projects. Proud to be a sponsor.
Thank you! ;{)------
@@KeithFenner You're welcome. Granted a small contribution on my part, I believe you will inspire others for another generation.
Best regards, Mike
The setup you made is a thing of beauty. How you figured this out is beyond my understanding. Great outcome Keith.
Great series for sure, lots learned and many questions answered. Top class.
Thank you so much for this content. My field of work has nothing to do with yours but I did some machining in highschool and I guess that's where my interest comes from. I highly regard how you do your job. I really got thrilled with that first full cut!
Brings back memories of Frank Edwards Machinist and engineer. My tutor, I first saw this procedure back in 1980, on a flat belt southbend lathe. In olden times people got by putting imagination into actions. This was a time when there was a imputus on female engineers in the work place. This proves the skills in the past can still be used to create works.
Thanks for doing this one. I like your use of "giant" through hole boring bars.
thanks for all your videos, they are top notch !
Great video as always.
Even retired, Keith still maintains his bearing.
Hi Keith, As always with your video's I am phenomenally impressed with your setup's and the quality of your results, just wow - that's not something I say very often!
That was a testimony to your skill as an engineer and a film maker truly bloody Brilliant thank you.
Hi Keith, I've messed around with some machining but am NOT a machinist in any sense of the term. Hit your channel bout 2 years back and haven't stopped watching. Really like your Out-Of-The-Box way of doing things. Ya got me hook, line and sinker. Carry on carrying on.
This was a superb video series all around but especially due to the interesting setup and the super camera and lighting work and mirrors and all. Wow.
from the first pin line bore I saw get fixed up. I wanted my own Portable set up. Now I see your work and I really got the bug. Your video and work are above the box.
Keith I am very thankful for these videos, I have a block of my own that I am going to put new caps on. I have been thinking about different setups and will use yours, all your videos are great.
Great job on these main caps Keith!!Thanks for sharing tje knowledge!
Great work Keith. precision at its best. Thank you for all your great videos buddy. Thom
Because you can. You can most of the time. Wonderful stuff Keith. Cheers
All I can say is WOW!!! That is some machining Keith. Incredible courage and experience to pull that off. Thanks for sharing.
Amazing work Keith! Even as a hobby machinist it always astonishes me how often HSS tool bits perform when new age inserts fail to deliver the required results.
I have heard it said Carbide likes work pressure and minimum cut of nose radius plus some. Its not a .00# cutting tool and microns? - forgetit. HSS can work down there. Great educational ‘cause I can’ series. Its been three years, but I would bet the bar and bearings did not find other work n maybe got lost in the move.
This is just very nice work. Way cool that you shared this job with us. Looking forward to the next video... ☺
I really appreciate the thought process and the carbide,carbide, HSS explanation.. You have earned the title of "Master Manipulator of Machining Metal"
I can hear the satisfaction in your voice as you dialit in,great job
I still remember having to pull the bar for accurate measuring. A necessary evil for sure. This is taking me back big time and I sure appreciate it my friend. WELL DONE EH ! Great video work !
Steam Turbine and all kinds of pump cases, closed bonnets and all by feel and guts, in the yards were a regular diet. ;{)-----
A really excellent series. Thank you
Good series. Appreciate info on tool bits. Thank you.
Thanks for taking the time to share that.
Great content true to your word because I can. Fantastic setup work camera angles were spot on 👍
First class Keith. A very inventive approach.
Keith, nice setup, a tip, back in the mid 80's I did quite a bit of work on v4 and v6 outboards, had to repair the mains on several of them, built a setup very similar to yours with one notable difference, to set my tool bit depth, I bored an additional hole next to the bit for my kwik-way boring bar micrometer, it would snap into place,( just like it did on the engine boring bar ) I used a small spring ball detent set screw ( the screw you use to back up your tool bit ) and it would provide just enough thrust against the tool bit to push it against the setting face of the micrometer. I would then lock the bit down with two set screws, made for fast ,accurate and repeatable setups
My grandson figure out my smart TV can play TH-cam videos, today was his first day back to school. I got to watch my type of fun TH-cam channels, my wife walks in and your at the reflection filming at chamfered cut and you stuck you hand in the shot to feel the corner. My wife walks in and said “omg that’s the ugliest B--Bs I have every seen, what are you watching p--n! “ me “yep!!!” Her face turn red when she saw it was just you hand. Thanks for sharing and making my day.
Keith: I'm sure there probably easier ways to do this operation but thanks for choosing this one. This is very educational and very interesting to watch. Good job....
Keith, well played. You are absolutely right that this approach is NOT for production work. However, the different techniques and approaches you took, showing different ways to do things, and there is no substitute for the experience you provided in setup and work holding on this. considerations for tool placement and anticipating what can go wrong were absolutely spot on. Kudos on the various "school of hard knocks" knowledge you shared in this video! Git er dun!
Expert work on display here...
Hey Keith what a very cool setup you made on the lathe to a line bore on the Block very cool video as always and I'm sure Dennis and the boys will be very pleased with machine work thanks for the video Scott from the cape
Fun stuff! Just to mess with ya: When was the last time you had that torque wrench calibrated? When I worked for Deutz the main caps were torque-to-yield. No torque wrench used. Hand tight then so many degrees all around, then so many more. About four passes and they were done. The bolts were never reused. I was Warranty Engineer but for some reason I was always called on Friday afternoons when there was a crisis build! Oh goody goody! Good times. Half the German guys didn't speak much English. I spoke a little German. It was fun for six of us with the one guy that spoke both translating while we were spinning wrenches! Help build an engine with all the needed accessories and get it ready to ship. German beer and pizza for dinner about 8:00 wrench until 10:00 and Dyno that SOB. Yes we had a BIG dyno... Crate it and wait for the truck to show up at midnight!
You mentioned torquing on a Deutz engine, this reminds me of a Deutz engine (I think it came from a Magirus Deutz truck) that came to my friends workshop for overhaul way back in the 1990's. It was an air-cooled diesel engine, and he just could not get the front pulley bolt off as it was so tight the like of which he or non of the mechanics had experienced. They tried heat, a strong bar and long pipe, shock but the bolt stayed put. They finally did get it loose after a day or two of struggling and researching, I am not sure how.
And as you say the bolts were never to be reused, it would be so for a high spec engine like that.
