Couldn't be that black axis at 0:55 repleaced by an darkbluish grey one with stop and the grey 1/2 bush put on the opposite site? That would make it a little more robust and not bigger.
the regular horizontal differential slips/pops a lot when I put it under high load; custom differentials have the potential to be stronger, plus they're fun to build the new 28t two-piece differential is strong enough for most applications though
I don't know, probably you could modify this one if you need to (for example make it stronger using part 87083 (www.bricklink.com/v2/catalog/catalogitem.page?P=87083 ))
One constructive criticism I have to mention, the first sign of torque and that idler gear is popping off. perhaps change the axle you used to attach it, with an axle that has an end stop? otherwise a cool idea and good execution.
An idea I had a while back was to use a differential in a dual engine design, as opposed to a pair of clutches, where the outputs and the input are swapped (aka engines 1 and 2 drive their respective half of the split axle, and the rotation of the differential powers the rest of the mechanism). In addition, it appears that since only one axle would be spinning at once, it would be geared down, partially reducing the drop in power when only driving one engine, and making the transition between the two smoother
i think this may work out for me as i only have a few pieces, i donth think i have that big dented gear but ill see if i have something to replace it, still im looking for a differential with the most basic pieces, dont care about the number of pieces, the thing is they have to be basic technic pieces, thanks man😃
No, it can't because of the grey connection gear in the differential's housing. It's only fixed by that grey 1/2 bush, which would jump off the black axis when load gets just a little higher. So the LEGO differential is better because it's smaller, cheaper and more robust. (I am building LEGO MOCs for several years now weighting between 1-2 kilogramms and those heavy duty vehicles haven't broke any of my differentials up to now)
@@npljojo i guess its depend on the speed you have. They not that strong on high speed and torque. I dont like to use them at all. I think 2 motors is beter then dif. After you wrote it, i realy was curious to see your channel and builts- but nothing in it... That was desapointed.
Yep, in this case it would probably help to replace the axle and bush with an axle with stop, I don't know why I didn't think about that before recording the video
It's actually not a heavy duty differential because of the grey connection gear in the differential's housing. It's only fixed by that grey 1/2 bush, which would jump off the black axis when load gets just a little higher. So the LEGO differential is better because it's smaller, cheaper and more robust.

As far as I know, it works until about the same torque as the Lego one. If it still skips, you can also modify it with part 87083 (www.bricklink.com/v2/catalog/catalogitem.page?P=87083 ) and it works under even more load...
Why would you ever do this? Not only have you built a just as bad diff with a single bevel, but you also made it larger and weaker... If there ever was a reason to make al larger custom diff, it would either be to make it stronger like with 4 bevels, to make some self locking diff, or to make a torsen like diff. All this can and have been done, but I have never seen anyone make a worse diff, and can't see any reason to... This might sound harsh, and it in deed is. This is simply a bad idea, a bad execution, and a bad result. Yes it is a diff, but it will disassemble itself in no time or destroy the gears in any practical use where it is exposed to any level of torque. I have a set of challenges for you (point 1 to 4 you can use any resources, and even copy builds if you want to, but the important step is 5, and that should be all you! 1: Make a linear differential. This is a diff that has all gears along the same axles, and it possible to build in a number of ways with todays parts. It can even be built using only parts from the 90's... 2: Build a 4 bevel diff (total of 6 internal gears, two sol gears and 4 planetary bevels) within a 5x5x6 volume. 3: Build any kind of self locking diff that can withstand the stalling power from a PF XL motor. 4: Make a solution that takes less than 3 studs of an axle to give it a diff. The diff function it self can be placed outside of the axle, but the complete axle should only spend 3 studs on a diff function including bracing. (This is very helpful on compact steered axles) 5: revisit this idea and see how you could make it better. :)
