Not to diminish the CNC gurus but the people that designed and built these machines were brilliant and that was way cool Keith.
It is more difficult to create a mechanism that creates complex features than a computer algorithm which moves stepper motors to the next position. That is why we have CNC machines today because they are simple compared to a machine like this or other fully-mechanical systems. I love these types of machines, they show a lot of intriguing designs! I wonder what mechanism they use to still drive the spindle even if it off axis.
I agree 100%
I was just about to post the same. That is some impressive engineering that went into that milling machine.
I totally agree, I hope CNC machines never replace these beauties, these machines were designed to do exact work and if something ever happens that computers can’t be used, hopefully we have enough machinists like Keith to do the job, upgrading isn’t always better.
@romanvarcolac2238 complex to design definitely. Though at the same time often surprisingly simple solutions to achieve it
Cutting circular arcs is the one thing (for most people) that separates the ordinary knee mill from entry-level CNC machining. What a joy to see a purely mechanical solution.
Good morning from Germany. This K&T Mill is a masterpiece of toolmakers.
It's absolutely amazing how that mill was designed and built to function as it does.
@@jackgreen412 In an era without computers Sure added on but the basic machine is just some engineering marvil BUT a machine is just as good as the operator and Keith is something special
@steinjonah660 You are absolutely correct about Keith operating the machine. Years ago had amicable disagreement with a gentleman about computers. I thought the computer was limited by the person setting up the program or inputting information .
In 1982 as a young, fresh engineer I have a vivid memory of walking by a machine that was cutting an o-ring groove on the OD of a large (18 inch diameter) aluminum housing. The machine was awe-inspiring. And, it reminded me of my mother's KitchenAide mixer. I don't recall the make and model and I never ran across anything like it...until this video! This itch, after all these years, has now been scratched.
While a machine like that wouldn't be used often, when you do need it there it is.
Often just one major job would pay for the machine and all the labor, leaving you with this sort of machine in the shop, which then allowed you to bid other jobs that needed the machine. Well worth it if you could get that first job.
I still stand by my initial assessment upon learning of these mills: The coolest milling machine ever made. There are others that are even more versatile and intricate, but this one's got the cool factor down pat on account of being extremely well made and thought out.
And it's extremely accurate. Clearances are easy, the machine is capable of fitting parts as well!
And I want one
The best machine in the world still needs someone who knows how to get the best out of it and enjoy the process of doing it. Kind regards Tim
@@EngineersWorkshop and all of that with just a 3/4 hp motor. The machine is so tight it hardly needs more. Working to get my electrical sorted so that my 1969 machine (480V) that was built for the U.S. Navy can get up and running. It's a beautiful piece of engineering and a big old slab of cast iron lol.
@@PA_3 Is yours one of the inch/metric versions? Short table or long? Power knee?
I find it amazing how creative the people were who created this type of machine.
Keith, it is a joy to watch a beautifully engineered machine tool doing the work it was designed for. Thankyou
Best milling machine I ever used. We had one of these when I did my apprenticeship 30 years ago, and a whole fleet of Bridgeports, but that thing could do almost anything...
With subtitles, you once and a while you get [applause]... very appropriate 👏
That you are using this old, amazing machine to do work it was designed for is very cool. That you are doing it to help get a historic project like Tally Ho closer to becoming another old, amazing design into the water again? The cherry on top.
That’s an amazing machine. You should save that piece you cut out as a souvenir or do a give it away.
That machine is incredible, as is the man who operates it, big respect Kieth
@75 I want to thank you for keeping our craft alive. I also had a shop in my home Garage where I have built many usefull items. I realized my machinery was underutilized so I sold the shop off to younger men about 10 years ago. I still have access to a large machine shop that is heated although it is 15 miles away(heated in Wisconsin means minimal problems with accuracy and deteriation from moisture and rust as well as a stable machine metrologically). I now have access to CNC + CMMCNC and tooling to the end of time thanks to a younger brother and his sons. My projects are still interesting and I am careful to schedule work for open machines. I realize consumables are still needed and am appreciative monitarily when tooling is required. I was impressed by your touch probe. Is that a function of the the machine's DRO? I had toured the Milwaukee plant with a friend of mine who worked in the service department diagnostics on the CNC equipment (PDP-8 circa 1989-90 ?). I really think the equipment of the day was more experimental than practical. While useful, many of us earned a lot of money repairing and diagnosing problems Many were mis-understood as electronic when a simple adjustment fixed the problem. I seem to recall loss of zero issues cused many mechanical issues with collisions etc. The machines of the early to mid 90's were the start of the unprecedented accuracy of today. I recall seeing a robot installing lifters into lifter bores I think about 1995 - 8 at a time! Thats when I understood Monarch, G&L K&T Gisholt and the rest were in trouble! I was also involved as a customer advocate during the retrofit years (about 1992 thru 2000) box ways and tercite casting was effective but delayed the inevetable progression to our machines of today. I really enjoy your channel Thank you for the content, I enjoy your commentary on thought process I find myself agreeing often and learining on occasion!
Tally Ho was splashed last week. Its rudder has the tiller fitted now so i presume engine trials will ensue this week. Going to need its anchor asap.
never knew about those machines. what fun
I did technical drafting for many years. I learned that, just as in your drawing, having an iso drawing as an overall "picture" is very helpful to keep the overall goal in mind.
Love this series, thanks especially for the setup info and details.
What a phenomenal piece of machinary. Great seeing it in action.
Nice job Keith.
Hello Keith: Be sure to lock your quill with the large nut when the quill is not being fed, also, when not using quill feed, be sure to put the feed selector in neutral to avoid wear ... Trust me, you do not want to have to dig into the quill feed box.. Ask Grundy about it.. Cheers from Louisiana; Mike
I got into CNC machining a year ago and love it, but it never fails to amaze me what crazy things manual machines can do with the right setup and knowledge.
What an awesome machine! I'd love to see how the drive train transmits the power out to the movable spindle. Magic!
It's pretty cool to see - if you open that top cover you can watch the mechanism spinning around. K&T made some amazing machines and this one is top of the heap. Mine was made in 1969 for the U.S. Navy - and through some horse trading with Keith I was able to get some collets and the super cool universal head.
Keith, hope you're getting close to the end. Leo's in the water now. Another nice video.
Good morning from Missouri, USA. Made my living running one of these machines, 1958-ish, they’re beautiful. Sure is fun to watch how we used to do it. We did the math with a pencil and paper, what was an iPhone?
Careful now, You’re showing your age! Lol
I wear mine proudly too.
I was just an 19 year old kid who couldn’t get enough of that machine work. Made airplane parts at McDonnald Douglas Aircraft in St. Louis. Really enjoyed that life.
Good Evening from Australia. I always learn something on this channel, thanks Kieth.
That K&T rotory is impressive!
Oh crap I love that machine. To not have to set up a rotary table and all that goes along with that
Once again, Keith, a very absorbing video. I am afraid that I get so caught up with it all that I find myself holding my breath as the tool is making its way to the first cut, As the the actual machine, all before me have expressed what a wonderful piece of equipment it is, and hard to imagine how it is designed and built. None, I hasten, to take away you skills in leading it gently by the nose. Great stuff.
First time seeing a radius cut on a manual milling machine , I know that machine is only as good as the "machinist" thank you for sharing and God bless you always
What a great old school machine to have in your shop Keith. Thanks for sharing!
If I'm not mistaken Tally Ho should be in the water by now, will have to wait till Saturday to see if they got it done. Cant wait to see all your hard work sitting on her deck.
Absolutely wonderful to see a master craftsman describing his work so thoroughly and confidently. Thank you
Thanks Keith. That is a happy day. I'm glad your first job with your new found capabilities went well.
Right after lunch here in Normandy, well mid day anyway. Really enjoy watching...cheers rr
Electronics make the work much more easy. One of a kind coming along great..
This is a fantastic video. I would be happy to watch a lot longer video
I think about how many of these beautiful machines are sitting in corners gathering dust and it makes me a little sad to realizise that time has passed them by just like it has me. We it has been a good ride and I have seen alot in my lifetime. I am not done but diminished.
When I first started watching your channel, much of your work had to be outsourced to the museum. Now you have an incredible array of tools, for even the most esoteric job!
Wouldn't it be amazing to see a machine like this made from start to finish. A Swiss watch on steroids!
Never had the opportunity to even see one of those mills. Very cool machine indeed.
That was an interesting video. Amazing all the different machines needed to complete this capstan project!
Cool to see the mechanical mechanism.
What a phenomenal piece of machinery. You always do such a nice job.
Such a great teacher. Thanks Keith.
Outstanding....love to see how these old and well known milling machines are still doing a marvelous job....
Love the many machines you use brings me back into the shop every time.
That’s an amazing machine. Haven’t seen one of those before. Thanks for sharing.
Keith, you continue to teach me to be a better machinist. I learn something every time I watch.
Fascinating! Very cool machine.
Is there a specific reason that you are not cutting on the backstroke of the radius? Since it is a groove I would think that you cannot avoid climb-milling either way.
Anyway, that machine is a really neat piece of equipment, if only I had the space for one...
I wondered the same and would love to know the answer...
It’s very interesting to see your process in the milling. I also appreciate the proper use of the term “Dead Nuts” when getting something accurately milled (or leveled)!
That is quite the machine, I cannot imagine there are many left. For what it lacks in speed it makes up for in cool points.
I think it would be interesting to see that radius cut on a lathe. Offset the part in a 4 jaw chuck and go to town. Not an expedient way, but just another way that things were done, from what I have been told at least.
Spectacular it sounds happy and smooth. It looks great too. My “what if gauge” was pegged out. You make it look so easy. Thanks for sharing.
That is such a cool machine.
Indeed... that wasn't just nice, or cool -- it was particularly awesome. I think that machine is another fairly clear demonstration that before computers, people could think. 🙂
That new probe and the DRO made this video possible 😅
Keith, very dramatic lighting for the open. Please keep these great videos coming. Thanks.
Hail the algorithm!
#TallyHo !
😊
This is great stuff, Keith. So glad Leo chose you to do the work. This is one of the many odd milling functions that I've yet to witness. So interesting. Much respect from Texas.
Hello I am not a mechanist but I enjoy your videos. Your work is excellent. Keep going
It's interesting to see one of these things actually doing something other than collecting rust in the back of someone's shop. But truth be told I haven't seen anything so far that couldn't have been done just as easily and just as well with a conventional vertical milling machine and an X-Y rotary table. The biggest functional difference is, with the rotary table you'd be cranking the table by hand not power feed. If someone does a lot of really oddball jobs (and by that I mean much odder than this one) and can't justify a CNC, such a machine might be a good thing to have around. But otherwise, sad to say, it's just taking up floor space that might be better utilized otherwise.
I remember back in the 70's and 80's you couldn't give one of these mills away. Then a bit later the same could have been said about the X-Y rotary tables. No one wanted to take the time to figure out how to use them, and the button punchers with their CNC's could outwork them in any event. Now though I get the sense that there may actually be a renewed demand for dinosaurs like this. I hope so, because these machines really are a piece of American machining technology history and as such are worth saving.
What a milling machine, those Old School folks knew what they were doing. Very impressive.
I have had a Grizzly mill in my shop for a couple of years but never was satisfied how I used it. Watching your videos has been so instructional. While my mill is much lighter, so is my work. Learning these valuable techniques is going to save a lot of money over not breaking all my bits.
Very, very cool Keith !!!!!
Took a nice bite out of the job!
Thank You for sharing your demeanor and your wonderful talents
I like the old tear drop handles on the older machines. I thought I saw something in the machinery hand book about the over all dimensions of these handles?🤔🤔
HaHa We can see it in your face Keith, your having just way too much fun. 😂😂 pushing all those buttons and switches..
This is by far the coolest machine in the shop. I hope your imagination finds great uses for it. It is awesome to finally see in it action.
Too bad your DRO doesn't also take in a rotary encoder and a 4th axis for the spindle offset. Always calculate tool position. That would be slick!
That is a pretty neat machine.
But thank you again it's a pleasure watching you work
That was pretty darn cool. The finish on that wild cut was unexpectedly good as well.
Fascinating, always thought the designers of these machines were brilliant and of course your expertise in setting it up to achieve your aim, very enjoyable video.
It's an eclipse! That does leave a nice finish doesn't it?
What a neat little machine! I love it ;)
If you had done this with a CNC machine there would be no reason to watch, this old machine was a real treat. Thanks Keith
Some K&T dude back in the day with a love for extra complexity and an arbitrary hatred for rotary tables and boring heads just slaps the feature straight into the mill at likely 6x the cost increase of a rotary table and boring head.
Even more amazing is there were customers for such machines.
Chewed through it like butter, what a wonderful machine.
Whow, wat a beautiful machine!
Another great video Keith ! I am continuously impressed by your skills and knowledge. The Tally Ho capstan is going to be a work of art when it's finished. May I suggest you making a "build plate" and mount it on the capstan when you're all done?
What an amazing machine!
Hi from South Africa. Great to watch and i can't wait to see the capstan on the Tally Ho, now in the water!!😂
A well impressive milling machine, I'd had no idea that such machine existed 👍😎
Very cool mill, And congrats on keep it moving. I've been building tooling and gauging on EZ trak and Proto trak for thirty years, Wouldn't have it any other way.
Thank you Keith!
I can't imagine the engenering that went into that machine, that is pretty amazing 👍👍
Thank you Keith. I'm no where near anything of a metal craftsman. Yet you explain the process so well that I think...."I could maybe ...sorta...try that. (Not EVER) You are a Master!
I loved this video.
Watching you learn how to operate that beautiful machine tool is half the fun.
I almost bought one a few years ago but I was intimidated that I would never master it.
By the way, with your weight loss you may find you no longer have sleep apnea?? It worked for me. No more machines!!
I really like the lighting and editing in this video! Great content as always
I work with cnc machine. But never have seen this works with manual machines like this. Its very interesting, thanks for your works.
I work with Mazak vtc 300!!
Thanks for sharing Keith enjoyed
Great to see the radial milling machine in action!
Love that mill.
Thank you for another great video. Cheers
VERY cool piece of machinery. And the thing is in great shape! I wonder what that sucker cost new. The quality and consistency of your videos is pretty spectacular too. I dont know how you do it, especially having a regular job and a family. We do appreciate it!
Very awesome Keith
Digging you digging your machine. You can hear it in your voice as you say it.
Very cool machine- also cool that you know how to run it.
Wonderful process !!!
Impressive as always. Thanks.
Another great and informative, inspiring video! Thank you Keith!!
