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.
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.
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.
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.
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.
Troye Stonich Yeah, rare video, I'd actually like to see part 2. I'm 40 with 22 years cabinetry and carpentry knowledge. This guy left me speechless. I've rarely seen odd ideas turn out as well as they did in the creators head.
Donn DIY Never heard of Lada. Please explain more. I'm speechless about the build. I'm a master woodworker. The skills used were impressive. But the mind that said, hey, that will work.! Impressive friend
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.
Thanks for that. Off to the scrapyard then to find one as small as possible. I´m building a go-kart for my boy using a lawnmower engine but struggling a bit, anyway thanks again.
Hard Core Genius. Ben ain't ever seen "broaching" like that. Ben likes your style. Ben has subbed because he believes you are the True Mechanical Messiah.
I was wondering how you were going to shorten the halfshaft. They don't always weld too good. That was brilliant. Thanks for sharing. PS, don't forget the oil refill.
Instead of welding spider gears, why not cut off the un-used axle , weld it solid to a "plate" (which would be like locking one wheel) and that would multiply the output speed of the axle being used? Otherwise as you have it, the out put is still much slower rpm than the input (determined by the ratio of the original gears). Something to think about.... Woody in Georgia
If you put the drive in the wheel side you in theory up the gearing ..If it was a 3:1 diff it would become a 1:3 Would that be correct ..I am thinking of doing this for a boat project copying an arneson drive ...My engine will go to 2500k Which would make the output 7500 ...Which ties well with the Outboard leg i intend to use
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
Yeah! The master and commander of angle grinders is back! Spline cutting with angle grinder.. That is gutsy! Respect for pulling that one off! Looking forward to seeing the mower build. With that gear ratio it is going to be a 'fast mover'. Not much torque to power though brushes perhaps?
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.
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!
Nice splines :) What do you do for a living? at crossroads in life at the moment, and man, from your videos you certainly do stuff that's right up my alley! Great stuff man, keep it coming!
I see, actually when my exams finish next week I'll be working part time and restoring a few motorcycles in my garage. Going to live it a day at a time, see what happens. Good luck man :)
I made the previous tow behind trail mower with a BMW differential. Sold it unfortunately and promised to build a front mount ATV mower which I'm doing right now. :P
lol, there is a special spot in hades for those who do such things to 9 inch ford punkins, lol. that said, AWE inspiring mod and "alley oop tech" fab up. my inner teutonic craftsman cringed, my inner street mechanic cheered! the spline chewing and drilling hammer "drive lapping to fit" technique needs far more air time, lol. only caution i have for you is either flame harden those splines, or seriously limit hp applied (not much more than 50), as the originals ARE hardened on axles. hardened oems can take about 300 hp per side before dentally challenged, lol. great idea all around! old school jeep axles off cjs had removable wheel flanges fit onto taper and key outer end axles, those would probably be an easier mod (no splines to cut), but offer less parts availability, and fewer axle ratio choices. every auto parts store in america has bearings for you,lol. hope you show it in action!!
I am unsure if this will be reliable long term because the differential is only supported by one axle now, so there will be excessive internal play. I think that if you had repeated the axle shortening on the other side rather than a full amputation it may have worked better.
I don't understand why you did not use the original spline welded to the shortened shaft. Yes it would not be as strong as the original shaft, but neither are splines that don't fit properly. Splines are designed to reduce rubbing wear, the hand cut ones won't do that. It will probably be fine for your purpose, but would last longer with real splines.
Ok, I was impressed! Wanted to do an independent rear suspension not unlike what you have done. I was also thinking helicopter rotor gearbox using a 1 ton axle assembly. Nice job.
You should check out my crazy project. Two occupant submersible simulator. Takes two people up 20 feet, pitches up 50 degrees, down 40, rides up and down 5 feet and rotates 360 degrees. And can do it in one second if you have the guts. You are in control, and have surround video and audio. It could simulate a race car crash, but the bruises and pain aren't simulated. The sub it simulates is a brain child of my business partner and we figure that we could sell more of these than million dollar subs. The current simulation is an underwater jet fighter, which lets you go play with the Dolphins, Killer whales, and avoid the big guys, one swat with that tail and you're done!Many other simulations can be produced. See www.fb.com/aqvwc SeaBird simulation.
Not really an invention but, I get it. I built one. I built a vice on a hitch. A tool box on a hitch with a vice on it and a foldable arm for a boom with a winch on it powered by a ratchet, wrench, drill, or impact
So, essentially a sort of PTO. You should probably put some sort of weak link between the blades and the gear box tho. This is way overbuilt for the application and you might kill something with it. Probably something between the engine and the box as well.
Leave the wheels on it and the whole axle intact. Turn the Pinion shaft down, attach a mower blade to the Pinion flange then add a trailer hitch and tongue to it. Pull it behind a ATV, Side X Side, tractor or truck. When the tires turn the blade will spin. You just have to adjust the height by tire size.
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
Easily got our thumb up! Nice work. Really liked how you made your own splines (teeth) of the end of the shaft and they came out looking pretty darn good!
I am. Ending one for one of those reciprocating wood splitter builds ive seen on U tube my problem is cannot afford a gear box .I believe one would work.
amazing video it's nice to see that they're still folks out there that can do things for themselves really good video I enjoyed it I've been dealing with mechanical stuff myself since I was 8 years old and that was 51 years ago when I was a kid my dad owned two gas stations men are supposed to know how to fix things and do mechanical work and construction and all that other stuff today's kids can't do anything for themselves
Its challenging to narrow a rear end for racing. Very sharp the way you tackled this project. For me to do this i would have to balance the axles first or else the vibrations would be out of control.
Very clever solution, well thought. I have always head cast irons is difficult to welding? Thank you for sharing your amazing video. Look forward to your next project
