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.
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.
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.
Thanks for taking us all on that journey Keith, it was for jobs like this, and the repair jobs I originally subscribed to your channel. Having spent my working life in a machine shop, almost exclusively on a manual mill, looking at jobs though the eyes a turner gives new insight. Please keep it up.
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
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.
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.
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.
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! 👍
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 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!
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.
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.
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
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.
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!
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.
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
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. Robert
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 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.
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 .😊
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.
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
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 !!
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.
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.
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
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!
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.
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.
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.
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.
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!
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.
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.
I really appreciate the thought process and the carbide,carbide, HSS explanation.. You have earned the title of "Master Manipulator of Machining Metal"
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!
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!
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 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 .
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!
I am impressed. Having been in the automotive machine shop business I have seen this job in the past. However even in the State of New Jersey there were only a couple of shops that could handle it and those shops had the honing equipment. Thanks for sharing and I hope that you get another chance to do the job and use the set up again.
Steve, I thought of you as soon as I saw this series, and looked for your comments. Unfortunately the number of automotive machine shops in south jersey is dwindling. Schumer’s (formerly Sclangers). Is the only one of the old automotive machine shops in my area with the equipment and experience to handle stuff like this. Chris
There are a few Race shops that can still do this work, but like you said most of the shops are gone. My shop was full service but there was not enough demand for align boring in my area to warrant the investment in the equipment.
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 !
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
Very well executed. I wish you would have gone more into detail on the tool bits and their failures though. I am surprised that the carbide was such a brittle problem. I run my tool bit holes on centerline for mostly the same reasons as you stated with your above center. Since most cutters are top faced that automatically puts them above center even when the hole is on center and it lets you be able to orient and run the bar both ways. Sometimes I have to give some extra angle to the bit tip though to keep it from getting too negative on the rake. I really enjoyed seeing you tackle and prevail over all the challenges on this job.
I'm not a machinist, but the RPM seems pretty low for carbide. I'm not surprised that HSS was the answer. I'm not doing any SF/M calculations or anything, but 160 RPM on a 2 - 1\2" diameter doesn't seem right.
Your final remarks about tool offset were interesting. I served my apprenticeship at PSNS. You may remember from your days at Mare Island it was not uncommon in peak workloads for crews of craftsmen from other shipyards to be detailed in for a few months to assist. I was detailed several times over my career to Hunters point, Pearl Hatbor, etc. The details not only assisted with the work but transfused technique and technology at the shop floor level to the betterment of all. One technique for line boring involved the use of heel-dragger tools and consideration of trigonometry in calculating radial stock removal Vs outfeed of a tool whose cutting edge was offset from the bar axis and the consequent effect of the tool clearance angle, cutting tool grinds and materials, etc. My personal preference was Rex AAA because of its edge holding and resistance to chipping for most materials, Mo-Max for initial cuts in weld repairs, and Alligheny Lundum T-15 for cast iron in short bores etc & etc. Grind angles were all over the map. I recall one time when machinists from King's Bay and Pearl Harbor were huddled over a double suction pump case up on a HBM for line boring with a couple of experienced guys from Puget. I was lucky enough to be one of those guys. Tools and talk were passed around with hasty sketches of different ways of handling the same job. If you don't mind putting it poetically, call it a "technical pollination" spread by us worker bees. What a learning experience! I still have in my box the heel-dragger tool used that day (sharpened back a few dozen times.) Multiply that exchange with dozens or hundreds of others and the detail to relieve excess workload takes on aspects of a coloquium. Now, 40 years later comes Keith Fenner with yet more to think about. Technique in this kind of detail is never written in books and it's a crying shame it isn't. How many guys who line bore pumps, excavator booms, engine blocks etc have to reinvent the wheel because there has never been a manual treating line boring in the shop or in the field? Start writing Keith.
Technical Pollination is a wonderful way of saying " Sharing Knowledge". Similar to all of us sharing in this project and adding to this forum. My Father served is WW2, His in WW1. Dad would say if I knew half of what my father knew I would be a Smart Man, DITTO. This Forum with knowledge shared is a wonderful thing, I hope all seeing this can appreciate the wealth of learning and experience on display here!! OperaBass3, Cheers from John, Australia.
I didn't think you were going to get wealthy doing blocks,but the series was so good and full of innovative work around's and great photography,loved it:)
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
Hi Keith, out of all your videos I think I have enjoyed this series the most. Yeah, I am pretty sure I will never need to line bore an Audi block, but the techniques you show are applicable to many odd and otherwise undoable jobs that can be done if you know how to think it through.
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....
great work. you are doing the best videos. This is the stuff you must film, and you probably are the only one from youtube who dose this . Share ideas, Special jobs, creative setups, to get the jobs done in the shop whit you're tools .
I'm watching this video because I can. I am the master of my own destiny and it feels good. I'm taking control of my life from this moment onwards, thanks to you Keith. You're a real inspiration to those of us caught in the rat race who desperately want to go it alone and let the chips fall where they may. Now what was I doing at work yesterday? I need to prepare for Monday morning. Oh God, all these bills to pay. I need to remortgage yet again but my credit rating hasn't updated yet since paying off all those credit cards. How long can it possibly take? I should really do more overtime and get a second job. Sorry Keith, things to do. Gotta dash!
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.
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.
These 3 videos were very informative. Your explanation of the offsetting of the tool is worth a million to machinists worldwide.
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!
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
The setup you made is a thing of beauty. How you figured this out is beyond my understanding. Great outcome Keith.
Hey Keith! Sweet videography, not to mention the creative use of the machinery at hand! Bravo ... :-)
Wow!!! Seriously the best machining camera shot ever!!
I know right, Unbelievable precision AND found a way to showcase it perfectly!! well done, Keith!
Not a machinist but I certainly enjoy your videos. Amazed at how you get these efforts come together
"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

Kenneth Makes some nice Billet Main caps and you do a great job Line boring them .Love these in depth video series. 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.
Another great Video! Rely love the shots of the bore cam, makes for a good view of the bit cutting up close. Thank You.

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 .
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!
Thnx for nice very close up camera views. Learned a ton.
In the kingdom of interrupted cuts, the HSS is king
These are some very well made videos. Very relaxing too. High level work.
Keith, thanks for another great video and answering my question about your tool setting.
All I can say is WOW!!! That is some machining Keith. Incredible courage and experience to pull that off. Thanks for sharing.
I am impressed. Having been in the automotive machine shop business I have seen this job in the past. However even in the State of New Jersey there were only a couple of shops that could handle it and those shops had the honing equipment. Thanks for sharing and I hope that you get another chance to do the job and use the set up again.
Steve, I thought of you as soon as I saw this series, and looked for your comments. Unfortunately the number of automotive machine shops in south jersey is dwindling. Schumer’s (formerly Sclangers). Is the only one of the old automotive machine shops in my area with the equipment and experience to handle stuff like this. Chris
There are a few Race shops that can still do this work, but like you said most of the shops are gone. My shop was full service but there was not enough demand for align boring in my area to warrant the investment in the equipment.
thanks for taking the time and effort to actually do the job, video it and bring it out for our entertainment and education
Your a true machinist buddy I learn something everyone I watch one of your videos👍
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. ;{)-----
Because you can. You can most of the time. Wonderful stuff Keith. Cheers
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
That was a testimony to your skill as an engineer and a film maker truly bloody Brilliant thank you.
I absolutely love seeing u do a video like this Keith. Thank u
Brilliant! That setup was just beautiful. It did the job and that's what counts! Thanks for the videos.
Takes some great big balls to take on a job like this, when you're not setup to do it. Awesome ingenuity.
Very well executed. I wish you would have gone more into detail on the tool bits and their failures though. I am surprised that the carbide was such a brittle problem. I run my tool bit holes on centerline for mostly the same reasons as you stated with your above center. Since most cutters are top faced that automatically puts them above center even when the hole is on center and it lets you be able to orient and run the bar both ways. Sometimes I have to give some extra angle to the bit tip though to keep it from getting too negative on the rake. I really enjoyed seeing you tackle and prevail over all the challenges on this job.
I'm not a machinist, but the RPM seems pretty low for carbide. I'm not surprised that HSS was the answer. I'm not doing any SF/M calculations or anything, but 160 RPM on a 2 - 1\2" diameter doesn't seem right.
Your final remarks about tool offset were interesting. I served my apprenticeship at PSNS. You may remember from your days at Mare Island it was not uncommon in peak workloads for crews of craftsmen from other shipyards to be detailed in for a few months to assist. I was detailed several times over my career to Hunters point, Pearl Hatbor, etc. The details not only assisted with the work but transfused technique and technology at the shop floor level to the betterment of all.
One technique for line boring involved the use of heel-dragger tools and consideration of trigonometry in calculating radial stock removal Vs outfeed of a tool whose cutting edge was offset from the bar axis and the consequent effect of the tool clearance angle, cutting tool grinds and materials, etc. My personal preference was Rex AAA because of its edge holding and resistance to chipping for most materials, Mo-Max for initial cuts in weld repairs, and Alligheny Lundum T-15 for cast iron in short bores etc & etc. Grind angles were all over the map. I recall one time when machinists from King's Bay and Pearl Harbor were huddled over a double suction pump case up on a HBM for line boring with a couple of experienced guys from Puget. I was lucky enough to be one of those guys. Tools and talk were passed around with hasty sketches of different ways of handling the same job. If you don't mind putting it poetically, call it a "technical pollination" spread by us worker bees. What a learning experience! I still have in my box the heel-dragger tool used that day (sharpened back a few dozen times.) Multiply that exchange with dozens or hundreds of others and the detail to relieve excess workload takes on aspects of a coloquium.
Now, 40 years later comes Keith Fenner with yet more to think about. Technique in this kind of detail is never written in books and it's a crying shame it isn't. How many guys who line bore pumps, excavator booms, engine blocks etc have to reinvent the wheel because there has never been a manual treating line boring in the shop or in the field? Start writing Keith.
Technical Pollination is a wonderful way of saying " Sharing Knowledge".
Similar to all of us sharing in this project and adding to this forum.
My Father served is WW2, His in WW1. Dad would say if I knew half of what my father knew I would be a Smart Man, DITTO.
This Forum with knowledge shared is a wonderful thing, I hope all seeing this can appreciate the wealth of learning and experience on display here!!
OperaBass3, Cheers from John, Australia.
I didn't think you were going to get wealthy doing blocks,but the series was so good and full of innovative work around's and great photography,loved it:)
Great video as always.
Even retired, Keith still maintains his bearing.
Nice set up Keith and great camera work, thanks for the for showing us some great machining work.
Outstanding work! You are truly a " Master Machinist " thank you for sharing.
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
I can hear the satisfaction in your voice as you dialit in,great job
Thanks for taking the time to share that.
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.
Hi Keith, out of all your videos I think I have enjoyed this series the most. Yeah, I am pretty sure I will never need to line bore an Audi block, but the techniques you show are applicable to many odd and otherwise undoable jobs that can be done if you know how to think it through.
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.
Love to see how Buffy turned out
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....
great work. you are doing the best videos. This is the stuff you must film, and you probably are the only one from youtube who dose this . Share ideas, Special jobs, creative setups, to get the jobs done in the shop whit you're tools .
I miss running those machines.
I'm watching this video because I can. I am the master of my own destiny and it feels good. I'm taking control of my life from this moment onwards, thanks to you Keith. You're a real inspiration to those of us caught in the rat race who desperately want to go it alone and let the chips fall where they may.
Now what was I doing at work yesterday? I need to prepare for Monday morning. Oh God, all these bills to pay. I need to remortgage yet again but my credit rating hasn't updated yet since paying off all those credit cards. How long can it possibly take? I should really do more overtime and get a second job. Sorry Keith, things to do. Gotta dash!
LOL ;{)-------
Boring that not boring at all! Great out of the box challenge. Kudos on a great result!
What a terrific summary....such a good teacher.....
First class Keith. A very inventive approach.
Excellent video series Mr. Keith! Thank you.
Favorite 70s tool, "Hey man pass that over here"
