I'd like to officially file my objection and disappointment concerning the "reset" of the cutter for each pass not being accompanied by a typewriter "new line" bell sound... :D

You should make a graph of how often you use your rotary table for welding vs. how often you use it for cinematic shots of rotating parts

As someone who has worked with farm equipment PTO's all my life I can tell you having the PTO a few thousandths under actually makes life so much easier during hooking and unhooking simply becaue it gives a tiny bit of clearance for dealing with all the crud that ends up in the couplers.

05:48 that animation was great. I was kind of lost on why it looked like it did and that cleared it up perfectly and super well! Great video!

It never gets old watching other people work

Love those 1st time projects. By the time your done you kinda know what your doing. Great video Tony👍

2 @ThisOldTony videos in one week!?!? I must be dreaming, this is amazing!!

Mr.ThisOld these nice short videos are awesome! Hugs and kisses!

Tony - another beautifully-done video. Very informative, and lovely to watch. I'm amazed that you can 'crank out' so many videos, and keep the quality (and entertainment value) absolutely top-notch!

The animations for each process is much appreciated!

You're very skilled. Good job.👍

YOU ROCK! This Old Tony is my favorite machinist based KZfaq channel! Being a broke as wannabe farmer, this one hit home. Thank you Tony please keep up the good work. BRAVO!

I appreciate the effort you put into that transition behind the machinists handbook.

Another great video. The "Good Book" comment made my wife snort with laughter. Keep up the great work. And thanks for the meatball shirts!

You're a teacher for life. I learned a lot from you this old Tony. Thanks a million

Another TOT masterpiece! You and Some More News are my favorite things to watch, thanks so much for being awesome and sharing such great content!

Dead nuts... Or on metric- spot on

I'm a simple man. I see a new "this old tony" and I drop everything.

you are officially the number two 'this old' search suggestion after this old house. congrats.

When i was young, i never thought that i will watch Machining Videos bevor Breakfast :-) Thank you Toni for Sharing.

Tony, your videos are educational on many levels. Big fan. One request : can you make a video on the cutting fluids: usage, types you use when and why, what's your setup is like ? how fluid cleaned ( any skimmers? ) . Looking forward to see it on your channel ! Cheers.

The first clip gave me an anxiety attack!

Your part of my daily therapy Tony Thanks for the great videos. They keep my mind and brain going.

If Tony released a 30hr long video, I'd still watch it, this man is the business.

I was on the lake fishing and had to stop to watch. Great video. By far my favorite KZfaq channel.

Now that you've got some experience, making it again will be a lot easier when he finds out that it needs to be heat treated to survive.

Thanks for the infotaining video as always, Tony! And how serendipitous; I just broke the gears and internal spline in my electric tractor PTO gearbox. Will be a fun fix...

This was not something I was wondering about when I woke up this morning. :D One always learn something new everyday. I enjoyed it!

Could have done it perfectly with a fly cutter and a ground HSS form tool. Would also have been an interesting video!

The nicest thing about smartphones is being able to watch TOT during conference calls. I live in fear of a surprise joke, but otherwise, makes it all better.

Another great video Old Tony! Always love your stuff.

That looks exactly the same as every spline I’ve ever seen in my career as a mechanic. I’ve never seen one with the curved depression between the splines, although 99% of what I’ve dealt with is metric. Nice job!

I confess... I'm the one who was yelling at the screen that your cutter wasn't at correct height.... until you made subsequent cuts.

you forgot a very important feature, that being the locking groove that runs around the circumference. A ball bearing in the female part locks into it to prevent the shaft from sliding off and entering a low earth orbit. also on the reason for the drive groves tapering back to the od it happens for a few reasons. 1: feature of manufacturing 2:reduce stress points 3: as they are used on machinery that operate in very dirty conditions it is common for them to get covered in dirt. When the female part is installed it pushes the dirt along the grove, if the grove came to a flat face it would pack the dirt hard against it preventing it from seating fully therefor not allowing it to lock in place. The feature helps evacuate the debris

I work at a machine shop, and once in a while, we have to make PTO splines. The machinists always do it the way you just did!

I'm a welder and have absolutely zero knowledge of machining nor do I have any plans to get into it, however I find machining videos fascinating and yours seem to be the most entertaining 👍

Let us know if it fits, breaks or drives. Interesting, most of youtube machinists make tools and stuff for there shop. Real life useful projects are quite rare even here on my favorite channel. Reminds me of my early days on citizens band radio where i figured out quickly that non pros used it exclusively to talk about there radio.

Picking up after someone elses guffaw is always tough. It usually takes more time and be better starting from scratch. From experience most of these 550 rpm drives are badly worn for sure. So all your head scratching and milling will be just fine fella.

This is a staple of knowledge sir… thanks!!

I appreciate the ingenuity on this one. Very clever.

my favorite pto is the one on my kitchenaid stand mixer. one of these days i'm going to bring stand mixers into the machine shop...

"no one should get their hand torn up on it", hell of a statement when it comes to PTOs. 😕

another thing i need to do too.. a picture explains more than 1000 words. which brings me to a project you might be interested in: -a centering stand for the mill, i didn’t buy one yet...adjustable up and down, thread fed centre.. :-) great job, thx. better than most tv news channels and talk shows.

Thank you Tony I have no tools, but I still enjoy watching.

I don't even know what a PTO Spline is, but i want to learn either way...hahaha Thanks for all the awesome content... I always learn something while enjoying the entertaining dialog and goofy edits... have a great day, take it easy... I use to call "dead nuts" "gramppa" 😜😜

Video has been posted 34 seconds ago but it has 20 likes already. Now that is what I call devout followers (including myself)

You never cease to amaze and entertain!

I always took the parts out of the lathe and piled them into the stolen shopping cart. When the cart was full (heavy) we pushed it into the building next door. The old guy that owned the company would brooch the splines. I never had time to peek in there and see how his brooch machine was setup but it did nice work on those splines.

Thanks for the tech, Tony! Still wondering how the heck 5' long spline shafts are machined...There's more than a few otherwise great glassblowing lathes out there in the world that get written off as a loss because of spline shaft damage. Usually this happens when the new owner was an idiot and strapped the machine to a trailer by the spline. Anyhow, from what I've heard they are very difficult to source and machinists hate making them.

Can we finally have a walkthrough of your shop?? Nice video too.

Great musical choice, awesome cinematography. You're getting really good at this video making stuff!

Great video!! More of these projects/ short videos. I literally rewatch your videos like an old person watching reruns of CSI

My wife's immediate reaction was "Lucy, you got some 'splining to do!"

I really was expecting more cursing and smashed hands. I mean at least that's what happens whenever I handle a PTO spline.

These videos are the unbelievable. You should be in television

Amazing! I need to get set up like Tony! Thanks for the awesome videoTony! Keep them coming please!

i just wanted to go to bed but... Tony... Well... here i am.

Today on This Old Tractor...

Nice choice of music. Your videos are very therapeutic - especially in these hard times.

Great Video Tony! i love taking what i learn and bringing it back to the shop

So what's the verdict? Was the cousin of a friend of someone who is the acquaintance of a complete stranger happy with the results?

Looks dead nuts to me, nicely done Tony!

I really really wish I had the equipment and knowledge for cutting splines. There's some great old equipment out there that could use new splined parts and this alone is causing these cool machines to be placed on the scrap heap. Thanks for sharing, you did a great job, BTW!

I have considered, but never tried this approach. Nice to see it in practice. Thanks

"Pacifically". The best trolls are the subtle trolls. :D

Wow, the videos coming in at a much faster rate now, I love it! Is it because you can dedicate more time to filming and editing because of the Patreon?

Awesome skill set and machine work. I've seen many car CV joints that look exactly like PTO fittings

awwww TOT has a cutter that purrs & chirps....Happy Cutter Happy Human!

Y'see, I thought PTO stood for Pachman-Turner Overdrive.

Tony, you should do a episode with Ray Magliozzi from car talk

Loved it Tony, perfect home shop, make do with the tools ya got kinda job.

Love these videos Tony. It is clear that you have forgotten more than I will likely ever know when it comes to these subjects. In other words, thanks for making me feel stupid.

II don't always go Full Screen. But when I do I'm watching T.O.T or AvE.

Great video! I was contemplating though......would it be cheaper and faster (albeit less fun) to take a 540 rpm to 1000 rpm adapter and cut the 1000 rpm end off? In doing so, you would be left with a perfect 540 rpm splined shaft that could be attached to whatever it would be needed attached to.

Outstanding given what you were given to work with!

Nice work! It’s cool to see how you tackle problems with what you have available.

Bet you're startin' to miss that shaper right about now, huh ;P

Could you make. Follow along series for beginners. ...... Sort if like Making a project that is made up of multiple parts that are not mega challenging.

Excellent job, Tony. I'm considering a similar job so this is very relevant. Top marks for video production too. All the best, Mart in England.

The best way to do something the wrong way, great work Tony!

Don't you have that fancy extra axis chuck on the CNC lathe and a lot of small endmills and time to waste programming weird paths? Old problems require modern solutions!

Hey Tony! What's your vocation? I'm graduating from engineering school this semester, but I've found that the majority of work in my field is desk work and analysis. We only have 1 manufacturing class in our entire curriculum! Your profession seems much more interesting. So what do you do for a living and how did you get there?

Love the computer graphics, made the effect of the first two cuts crystal clear

It is very valuable to show how to do parts with a manual machine, also the procedure to do it. This skill needs to be retained so the knowledge isn't lost!

It won't work properly. Notice the grove around the shaft at 0:52? This is required to keep the 'knuckle' end engaged to the shaft. There is a little pin with a notch in it that is pushed out of the way then engaged in the grove and held in place with spring tension. What you built is very nice, but as soon as lateral movement is applied, it'll slip off the shaft.

I think you should have turned the shaft down to the minor diameter, and then cut six slots for keys. Then just turn the OD round. :-)

Solving a problem with what you have is so rewarding.

See there is always another way to do something. I like it. Very useful information. Thanks for sharing.

thats too many steps for me when my fridge is only 14 away

Do let us know if it works or not, if you're told of course.

Love your vids, Tony. Thanks for sharing!

Really love your videos! Keep em coming!

You go to all that trouble and then you find out that a PTO spline is 1-3/8" 6 spline, just like a Big Block Ford clutch...

So like Five different people commeting first

Good stuff...as always. I like doing those "one-of-a-kind" jobs. Sometimes they're quite challenging.

Thanks TOT, you read my mind. This will be very helpful if and when I need to cut some splines for a project I have in mind. 🙂❤

Wow, 1 view - 6 comments 😁

This is the best name for a KZfaq video ever.

I cut a couple of splines just like that back in 1988 at Aberdeen Proving Grounds, MD working for my uncle. If I remember right it was on an old Van Norman horizontal mill, nice job Tony!

This video brought back horrific memories of installing Mack transmissions into an improperly aligned clutch. I'd rather give birth than push on a 1000 pound trans with poor fitting splines. I hope your distant friend appreciates the quality work you did here.
