I am a third-grade teacher in Texas. The reason I watch every one of your videos is because you exemplify the thinking that I teach my kids every single day -- be a problem solver in every facet of your life. You have many complex machines at your disposal, yet you still have to come up with unique ways to complete each job (thinking outside the box), not simply "throw it on a machine". Thank you for sharing your expertise. Keep up the amazing work and by the way, your wife's camera work is some of the best on KZbin.

[@johnmcclain3887]

You remind me of teachers I had fifty to sixty years ago. I left school at 18, was at work at 11, got my education in my thirties and forties. Now I get to enjoy watching others do what I did for so many years. I've been retired for a bit over two years now, ahead of any desire I ever had. We got told we could do anything we set our minds to accomplish. I hope you can impart that to many of your students.

[@TheByard]

I left school Easter 1960 with just a secondary education, started work in construction, my father was the works superintendent and when every he came out of his office my name was the first he called. I was taught to drive every item of plant on the job and would jump from one to another as needed. If it broke, I had to help fix it. I also spent time as the boy at each of the trade depts, learning their trades. When I asked why every trade and father said it's always good to know what another man's trade has to do before asking them to do it. I then helped build a Tunnel Boring Machine and mastered the controls, I'd already had spent time with the surveyors so understood lines and levels. The TBM was fitted with the first Line & Level guidance system and gained knowledge of that helping install it. So, when mining started I had it off pat and only needed to find how the TBM reacted and became one of the three shift operators. After 20 years of tunnel building and many different types of ground and been promoted to tunnel foreman. I called up a consultant company for information and they offered me a job as Senior Inspector of Works this commanded a salary package equal to a graduate civil engineer with as in my case 20 years' experience. So, for the next 15 years I traveled to many parts of the world working on major tunnel projects with that same company. I took a 4-year absence from them to work on a major High Speed Rail project, before returning to the old company until I retired in 2015. I put my father's training to good use by talking to contractors to solve problems, I also suggested to the workforce on a faster, easier, safer way of completing tasks. Most mining crews work on a piece work system and are payed on amount of tunnel completed. I would stop them getting into bad habits as rework would slow production, I was rewarded by being able to sign off work and not write pages of reports.

[@timdouglass9831]

You know it's serious when you need a crane and forklift to move the tooling! I was particularly impressed that your bandsaw went through that hardened shaft without leaving teeth behind.

[@gregbrodie-tyrrell3473]

Bloody brilliant as usual, mate. Your lathe must have a very *rigid* toolpost to support that amount of overhang to allow such a huge bar to cut without deflecting significantly. Or am I missing something? Anyhow, congratulations to you for showing us another way to help us backyard blokes to improve our tool inventory, and also much admiration for Karen for her brilliant camera work; lots of people make videos, but hers really highlight how good your work is without being flashy. Good on yer both!

[@ohcrapwhatsnext]

Im wondering the same thing... It seems rather small for that tool...

[@SodiumInteresting]

being that big perhaps that makes it so rigid that the overhang effects nothing

[@wirefeed3419]

Very unlikely that bar is going to flex but that does seam like a heck of a lot of leveraged force transferred onto the tool post. I have to admit I was expecting to see the bar fitted onto a bigger lathe, either way he has shown he knows exactly what he is doing I have little doubt he has considered and knows exactly that the tool post will handle that beast of a bar. I look forward to seeing it do what it was made for.

[@terryf8755]

I used to use a shop made boring bar that was significantly larger than this one. I do not recall the actual numbers (if I ever even knew them) but an estimate from memory, is that is was probably about 4 inches (200mm) in diameter, and over 12 feet (3 to 4 metres) long. It was entirely round, did not clamp into a tool post. Instead, we removed the compound and put into it's place a saddle made to clamp the diameter of the bar. We were boring steel cylinders that were about 6 feet (almost 2 metres) deep. There was no noticeable deflection, and it is difficult for me to imagine that our cutting inserts would not be destroyed if there was enough force on them to flex that bar. What the weight of that bar did do (with that leverage it had due to it's distance from the saddle) was try to tweak the carriage on the bed, making the friction rather high on the ways. That is why the boring bar was so long - half of it stuck out the back side of the saddle, toward the tailstock. That way the weight was carried evenly, it was balanced. The biggest issues were that the cutting tool would wear (we used diamonds and ceramics for their hardness over carbide) as you can imagine, the linear distance of the inside circumference and length of cut. The other issue, was getting the feed and speed right, along with the cutting tool geometry, such that the chips would break, insead of a bird's nest from a continuous chip hundreds of feet long. Imagine machining propellor shafts on container ships!

[@johnmcclain3887]

I've been doing this for fifty years, mostly retired now, still get great pleasure seeing you taking up where I left off, although I did at a substantially smaller scale. I worked a few years with a shop that made, straightened, and repaired boat shafts for a fishing fleet out of Morehead City, N.C. with shafting well on the same scale as your boring bar. We made most of our own tooling, as you do, out of scrapped out work. I really enjoy seeing "homeless" running around in the shop, reminds me of my younger days.

The time to make the video out of the footage. 1. You shoot the footage which takes at least as long as the job itself (obviously) 2. You end up having 4-10 hours worth of footage, sound and stills. 3. Editing that kind of material with all the bits of information embedded will take at least two days, usually a lot more. So, it definitely takes longer to make the video than it takes to do the job itself. Again, a polar bear sized thak You goes to the giggler.

Love the design. Sure it's going to work great. For future tools look at building a big boring bar holder that can bolt to the saddle directly instead of onto the tool post.

Unfortunately weak point in the whole operation there is the shaft the tool posts mounted to and may allow vibration with heavier cuts. Awesome work and keep up the great content

@@jed-henrywitkowski6470 Oh good. I wasn't sure if anyone was going to get it!!

[@prinzeugenvansovoyen732]

you should put a counterweight onto the end to reduce weight stress onto the toolholder, since your cutting forces gain a lot of leverage you should counter the asymmetric weight

[@henrikstenlund5385]

I am sure he will realize this while testing. The bar weighs 95 kg and then you add the cutting force. I would suggest adding some sort of extra support for the far out bar end pulling it down. The jaw of the tool holder will be heavily loaded.

[@chrisjohnson4165]

I was also thinking that the tool post is now the weakest link. It looks overloaded now.

[@henrikstenlund5385]

@@chrisjohnson4165 Perhaps it is possible to add another tool post or like to increase support.

Another great video, I always love the act of destruction in the process of creating a beautiful piece of work. Something about watching the teen fly. Karen, great job in catching the glow on the end of the ceramic cutter, and the flying metal bits. What does surprise me is not seeing comments from the other KZbin American machinists. I guess they are too busy taking notes.

hey mate thanks for the great comment glad you enjoyed the video. I think the metric measurements scared them off 🤣👍

Todo bien por aquí. Saludos desde Madrid, España, Unión Europea. Gracias por las clases de maestría que nos regalas. Feliz día.

Never seen a ceramic insert before, very interesting....thanks. BTW: I have a right angle drive for my bridgeport that fits on dovetails and quill. Very useful. I use it mainly for fluting rifle barrels.

And on this episode of "As The Chip Tray Fills" we see Homeless stalk some sort of lizard meanwhile the star of the show Kurtis fabricates a rather impressive large boring bar all the while filming by his lovely wife Karen shows the process and she's learning some new angles and camera movements! Great show like usual folks! And this weeks bloopers...my tummy hurts from the laughing!

[@captcarlos]

Karen, "Drop it!!" Homie, "Right, Your not the boss of ME!" Hahaaaa, pharq! That's not a bar for the quick change tool post for sure! Probably best with a solid post rather than the compound... I'll be interested how it runs, it certainly has some inertia...

[@gibbogle9486]

The camera work on these videos is top-notch. Very clear and very illuminating.

[@ronaldpiper4812]

Not sure what I like more. You working or interacting with the dog. The personal side is sweet. Then the profesional lathe work. nice.

[@jeffevarts8757]

At what point would you need to upgrade the toolpost? 95kg at 90cm seems like a lot of torque for 10-15cm of grip.

[@aan5393]

Well said it was interesting how he made but is it practical?
