CUT PTO SPLINES IN 18 EASY STEPS!

Ever cut a PTO spline before? I haven't.
Know what else I've never done? Bought the correct cutter to do the job. :(

[@tcmtech7515]

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.

Dead nuts... Or on metric- spot on

Oskar Tuulik I laughed so hard I Peed my pants a little bit when I heard that one.

[@semidemiurge]

Dead: exactly right . Nuts: A common and certainly apocryphal folk etymology is that the term originated from the historical poker games in the colonial west of America, where if a player bet everything he possessed, he would place the nuts of his wagon wheels on the table to ensure that, should he lose, he would be unable to flee and would have to make good on the bet. Since it would be expected that a player would only make such a bet when he had the best possible hand, the folklore says that this is how the best possible hand came to be known as the nuts.

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!

[@pcwizzzkid]

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

[@frodehau]

Yes, probably he just left that part out of the video. The axles I have has a springloaded pin with a milled section on it for locking.

[@pcwizzzkid]

That is a possibility. It is also possible that in the intended application it is unnecessary or even intentional to allow movement in the case of a one piece shaft opposed to the commercially available 2 piece shafts. strange things happen on backyard built machines. Yes on the early shafts it was a bolt passed through a hole tangentially to the locking groove then the spring loaded pins became popular however the are prone to seizing with corrosion or debris ingress. A spring loaded collar that seats ball bearings in place (think ratchet to socket only the locking ball is in the female portion) is becoming a more popular option.

[@stevenkelby2169]

The end user has a lathe. He can cut his own groove. I know this because I watched the video.

[@frodehau]

@@pcwizzzkid I don't care for those at all. They're quite a bit heavier, and close to impossible to release inside the PTO guard on some implements.

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.

[@docpedersen7582]

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.

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.

[@noeltinney6537]

Hi I used to cut pto splines on a milling machine. If you use two side and face cutters with a spacer in between on your arbor, the spacer can be machined to give the correct thickness of the spline. You can do both sides in one cut. Then clean out the rise in the centre. This means that once the cutters are lined your spline thickness is correct. The depth is of secondary importance.

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.
