I am 74 years old and have been around some very talented mechanics and fabricators while working as a certified aircraft mechanic. I knew two personally, I worked for both of them building one of a kind prop driven aircraft. Their talents were beyond amazing. They seemed to have the various projects mentally completed before they picked up a wrench. Their efforts were always spot on no matter what the project. I put you in the same class as those talented men. Three cheers sir.

I appreciate your skills and special thanks for demonstrating how difficult it is to convert automobile parts in to useful part for non automobile projects.

Have to add my kudos for the spline grinding. I've spent many hours using a mill and indexing head to make them. That was really slick the way you did it.

While grinding the splines was an artful demonstration, you had a lathe. You could have cut the splines off, turned down a stub end, bored a hole and welded the factory splines into the existing axle. No beating them. Very well done and interesting video.

Great job!!! Thank you for sharing!!! Be safe and God bless you !!!!!

Ok, you had me at splines! LOL

Many post-hole augers have been built in this way. They truly last forever. Great job!

Dude that was badass never seen someone made their own splines!!!! that is awesome

Not what I expected to see where you did the splines instead of a shaft splice. What a beautiful job and video production!

You are one talented man

fantastic, i though how are you going to make the splines on your lathe? grinder saves the day. Did you get the splines to work on your first attempt or did you use the other shaft ? great video looking forward to the next one

Good idea, nice work !!!

Good idea and great work

I have been doing this type of work my entire life. What I saw in this video is amazing. You should be working in a prototype lab and earning 100k a year. You have a talent that should not be wasted.

Seriously cool way to solve a problem with minimal tooling, excellent!

I remember watching this video years ago and thought then. Wow. This kid is going places!

Excellent job ... Professional

Love at first sight! Aw inspiring

Man You certainly are a pro. You rock. Such skill with that angle grinder!

Truly Beautiful Work !! Very Well Done! Great work on the Log Arch trailer too!! Subbed!

Absolutely amazing!!! i was thinking to buy a £300 90 degree gearbox for a project now no more. Your design is godsent!!

Amazing the groving by hand ! Well done as well !

That is true craftsmanship. Thank You for the informative video. Keep up the good work. Have A GREAT DAY! 🛻🚚😁

Run a pto off of a transfer case via driveshaft and you mount the axle shaft end through the bed of a truck with a capstan style winch head. Works best with standard transmission! Great video. Never thought I'd see this on youtube

Thanks for sharing this beautiful video

that was the most impressive display of freehand angle grinding I have ever seen.

his hands are nice when it comes to building great work with precise craftsmanship to the core

Awesome work

Dude, really nice job on cutting the splines! Freehand with an angle grinder? That's bad ass man. Can't wait to see how you put it on your mower...

nice machining.. looking forward to seeing the finished project.

amaZING VIDEO!

Genial 👏👏👏

Okay. You have my attention. That was awesome!!!

I live the idea of grinding in your splines.that looks very nice for free handing those bevels.

Automotive differentials are very useful items for homemade implements. I have an old post hole digger for my Allis Chalmers WD that utilizes a Plymouth (I think) diff.

impressive grindin skill! cheers.

Very good This must be followed.

Just curious, but why cut new splines? Seems like you could cut the excess shaft out of the middle and welded the stub with the splines back on. For those that might worry about alignment, clamps and angle iron would take care of that. And, in Donn DIY's case, he's got a lathe to help with the alignment. Bore hole for alignment pin? I don't think it would be any more "out of tolerance" than making your own splines with a marker and hand grinder. Not intended as a criticism. Just thinking out loud. Maybe I'm missing something...

You are a master with that grinder ,excellent work

👍 Excellent work ! 👍

Fabulous.

good job, good verry talented.

What a great job you did on those splines!! Great work bud!! Keep at it, as it is not only great for the mind, but as well for the soul!!

Отличная работа,браво!!!

Amazing! congratulations you are very talented. Cutting the splines with the angle grinder was priceless man! keep up the good work!

the spline making was genius!

Very nice work doing the splines,Great idea over all.

BRAVO NICE WORK

Amazing , i like it.

Отлично...!!! Особенно понравилось как шлицы нарезал...))) Ставлю лайк..))

Good sir best idea

Amazing idea to connect diferensial 👍

Congratulations! Great work

Really impressive grinding skills there

Laik garantido amigo

a work of art, very nice

i'd say excellent. FYI for others out there - many Subaru differentials are already cut down like this - if you can find one of them, it might work for your application if the ratio through the differential works.

Great job. Nice knowledge

I`m glad to see I`m not the only one who`s cut shaft splines with an angle grinder!

So nice video

this type of projects is one of the best for me

Lol, great video! Thinking of doing this for a large windmill down shaft.

One hell of a fabricator!

that MIG welding is strong enough for this kind welding job? thanks ´n nice grinder skil.

great job sir!!!!

Fantastic metal working skills.

awww what a cute lil rear axle

Awesome build! For some reason I would love to cut down an axle like this but I don't have any reason to right now! Maybe I'll find a reason and use some of the techniques from this video! Great video! Keep up the good work!

i really love your videos , keep up the amazing work

Brilliant!!!

Thank you sir you just blew up my mind with them splines on the driveline My hats off to you

This fellow is a very cleaver !!

Very impressive fella great skills

That would be a good way to up-speed a waterwheel too. Instead of hand cutting splines, I would have just turned the shaft down to about half the diameter of the splines. Then saw the splined end off the axle, drill down the center to match the shaft, slip it on and weld it in place. I've done that in emergency repairs a couple of times.

Excellent video ! 👍

Pretty cool idea and nice work! Before I found a post hole digger at an affordable price for my Ford 3600 tractor, I was thinking about using a rear end a bit similar to how you made yours

Nice work thanks

In the past we have used Triumph herald and jaguars diffs for right angle gearboxes, as they need no cutting . And if you use one “half-shaft” side as the "input" fix the other half-shaft so it won’t turn, then use the prop-shaft as the "output" it will be geared up around 4 - 1.

Very nice job u done

Excellent! what more can be said.

impressive free hand splining!

Nice job , came out nice.

That is the Angle Grinder King there!

Did the same thing, used it as a reduction box to power an auger off the pto of a tractor to drill 18 inch holes for commercial kiwifruit planting, nearly 40 years ago.

Superb

dang!!! you got some mad ass skills with the side grinder.

Gearbox ini sangat bagus luar biasa

Hey, making splines using grinder is something special.... VERY COOL!!!!!!!!!!!!!!!!

Well done!!

Ok Donn, 10/10 for the duplicate spline clever'ness.

VERY NICELY DONE , YOURE AN ASSET!!!

very nice work

Your skills are over the top ! Amazing 👍

Heavy duty! You can turn a lot of blades with that gearbox!

I can't wait to see the front mount mower build..

you're bloody good with that angle grinder mate!

I’m most impressed how you splined the shaft! 👍

waiting for final project great job

Well done! I am impressed with your work.

Nice video
