Would be interesting for u to do a restore or rebuild of the lathe since I first watched u kept thinking 🤔 he's gonna do it one of these days lol

[@mikebell9166]

Man! 2 videos in just a few days! This addition will enhance the trailer's maneuverability. It'll be easy to jackknife the trailer though. You'll have to watch that so you don't break important bits like your pto shaft. I'm really enjoying this whole series. There's just so much you can do with this rig, it's just astounding. Plow snow? Yup! Drag some broken stuff out of the woods? Yes, sir! Bring a load of firewood out of the thicket? Oh, yeah! Really impressive!

It feels like that trailer can pull an entire house!! so robust fabrications, i love it! congrats!

[@Hellsong89]

Little additions and it will become his travel trailer with tiny house on top of it. Just use loader to lift it off when not in that configuration. Could be pretty cool use addition if you want to travel to forest and camp in style.

Your videos are so relaxing to watch

[@thesickhorseranch]

Maybe you've got ideas for this in the future but the pivot pin is oriented in such a way that it will require the removal of the PTO spindle to remove the pin. If you inverted the pin you would be able to remove it separately for repairs or service.

[@SimonCoates]

Was just about to make the same comment.

[@alexaltrichter1597]

Pretty sure that pin would last roughly 7 lifetimes if greased occasionally.

[@Crewsy]

@@spangenbob That pin with a keeper tab on one end and nut on the other will never fall out. Never mind that there are several examples of popular OEM companies installing pins from the bottom. Usually because there’s something like a driveshaft or something else above the pin location.

[@fowletm1992]

Pretty common for the articulation point on big loaders and 4d tractors for the pin to be in from the bottom The driveshaft has to come out for Remo Al anyway but no ones lifting a 20kg pin into the artic frame and positioning it in the hole They make it so you jack it in from the bottom and then a retainer keps it in More offernt than not the pin doesn't have any keeper welded to the top or bottom its just a straight pin with holes drilled and tapped at both ends, makes it alot easier to machine So you can choose to bolt the top or bottom keeper on first but of course everyone does bottom first

[@SandBoxJohn]

Not only that, the pivot point of the universal joint should be on the center line of the pin.

[@steffendhonau]

[@jamesgulrich7416]

I had always wanted to build an ATV logging trailer and several years ago watching your series on rebuilding your logging trailer, I was inspired to build my own with my own twist. I built the thing so heavy duty that I have trouble pulling it around. Out of the four quads that I have, only one, my 660 Grizzly will handle the load, meaning the weight of the tongue of the trailer when there isn't a load on it. It collapses the rear suspension so much that the tires rub on the fenders of my other quads. When there's a load on the trailer, it balances the tongue weight a little better. Even my friend's side by side had problems and it bent the trailer hitch for the 2-inch ball. The trailer you are building now looks a lot heavier than mine right now and I'm sure your UTV will pull it just fine. So, now I've decided to build my own UTV! I'm going to have to find a donor vehicle for the build... Thanks for another great idea!

Thanks for the heads up about free cad. I’m going to try it, I’m currently using Inkscape and I like how you can see measurements in it. I built my cnc plasma also. Can’t wait to see this build when it’s done. I’m just finishing up a new log splitter as we speak. My son and I have been using the one I built over 40 years ago.

[@gafrers]

The tongue pivot should be in line with the center of the u-joint.

[@giovtomas]

Doesn't matter, it is not a homokinetic joint

[@henrikaki5883]

Tractor pto shafts can telescope something like 30 cm. It is actually good for them to move a bit in use so they dont get stuck over time.

[@twinstickwizard3941]

Actually the pivot point should be in the centre of the driveshaft. Then the driveshaft cuts the corner and allows a sharper turning radius without such a sharp joint bend. Look at any articulated loader etc and that’s how they are built.

[@leandrog1989]

Excelente trabajo! Saludos desde Mendoza Argentina

[@jamesmisener3006]

19:20 The tow bar pivot point needs to be centered with the universal pivot point on the PTO drive. Nice build so far. Cheers 🇨🇦

While it may still function as is you should still consider trying to align the tongue pivot and prop shaft U-joint. It’s always amazing to see your method of engineering.

Great measurements 👍

[@АртемАртемьев-м9л]

Great job👍👍👍there is one tip if you don't mind) it will be better if the axis of the D-pad and the hinge under it match. Thus, you will avoid biting the D-pad at high angles of rotation of the trailer.

To make great zirk fitting guards. Take a large nut drill out the threads than welded it around your grease fitting hole. 🤔

[@robertkeime4907]

[@damiankonefon5725]

Super 💪👍👍

[@aserta]

You can put the cylinder where the drive shaft is, behind the angled metal, and then use a pushrod setup (like in an F1 racing car suspension), using the triangle plate to divert the load around the angled structure, to the draw bar. It's a strong setup that is also beneficial in the sense that it keeps the cylinder hidden, you can basically put it under the structure, even at an angle (downwards) to keep water from messing the seal. For a pushrod, you can use any piece of shafting that's meant to take a load, but you can also use a tube with thicker walls if you have one gathering dust. Love the use of old stuff , i have a few cyilinders myself that i'm slowly going thorough, including a hateful one that fell on my foot when i was a kid. I'm saving that one for my brother's manure spreader. :))

[@erichill5208]

Nicely done like all I have seen you build on KZbin. Only design flaw I see is the pivot point for the tow bar should be directly inline with the pivot center of your pto u joint. Otherwise as the tow bar swings the length of the pto shaft will change drastically. Very cool build so far

[@Paulman50]

Great design. I don't think anyone in these comments could do better 🤣😆😂😅🤣

[@CJohnT]

I have 2 concerns. Shouldn't the u-joint and pin below it line up so that they rotate at the same point? Hopefully you won't have to replace the pin, I guess the driveshaft could be removed. Otherwise, Awesome fabricating skills.

[@DanKoning777]

[23:46]: Before you welded up the tow bar mount assembly, I was surprised that you didn't check the pin, namely to ensure that it hadn't bound up and could still be easily removed; but you know what you're doing far better than me.

[@foxtrotblueofficial9814]

I like it,

[@blainethompson6493]

if you every want to cut plate that is thicker then the piercing capability of the 45 you can drill an 1/8-3/16" hole at the pierce and run it like an edge start. i do it with 3/4" plate on my Hypertherm 85 all the time.

[@davidallinson2501]

I wonder why when using the hole saw you do not wind the ring down to push the cutter drive pins into the wholes in the cutter. Very easy to get off again as is not tight up against the threads. Great job. I have been watching many of your projects. Keep making the super informative videos. Thanks.

[@carmineriganti2333]

two thumbs up

[@-powerband-gamer-6117]

Very nice

[@kcraig51]

Shouldn't the tounge pivot be in line with the u joint pivot?

[@FullMetalFab]

With a collapsing PTO shaft it doesn't need to be lined up with the pivot.

[@mwilliamshs]

Not necessarily

[@jekyllman27]

nice video!!! The steering angle on my trailer is 45 degrees. This makes the trailer extremely manoeuvrable despite its size.

[@randytravis3998]

Great work Donn ,,it will make a mess if oil in the ram but you could test with air from a blow gun use low air pressure too test .. that way you could see if it will pull back on the ram ,, not sure if you will need a ram on both sides ?? time will tell maybe I will find out in the next video .. keep up the great videos ..

[@andreaboggia]

Nice!

[@chahidabdelmjid5653]

a lot of lesson in each video

[@NavyCuda]

From experience, using two rams is way better, one on each side connected in series if memory serves me correctly. Especially if you need to hydraulically lock the trailer in an offset position while towing. If you use shuttle valves for steering adjustment, get the connectors with leds to help prevent back emf.

[@robertogonowski9027]

You should make smal change. the pivot point of the universal joint should be on the center line of the pin

[@josephlee7325]

For your hydraulic cylinder on towbar double the thickness of your brackets on each end then weld a lapweld barstock on the top and bottom double bracelet in a couple of places to give you a few options for your cylinder

[@Franisboche]

Hey Donn, How do you plan on removing that tongue pin when the pto shaft is in it's way?

[@paavokaleva]

PTO removal is for about 2 minutes.

[@anindividual3889]

I think I kind of understand what you are trying to do with that cylinder. Disregard this comment if I'm wrong, but you're trying to make it so that when you turn, the movable trailer hitch follows you so you don't bend the driveline? If that is so, I would recommend using another pivot point right before your hitch pin and then make the hitch mount more stationary on your utv. Then you can run what I would refer to as a "Z" link underneath so that the trailer will follow better without kinking the driveshaft so to speak. What I mean by this is taking another solid bar and running it to a pivot point on the left on either the front or the back and then to the opposite side on the opposing pivot point. This would also help making your turns more of the same radius and take stress off of the whole system. I think this might be a simpler solution than trying to work out the cylinders, but I could be wrong. If I'm wrong in my assumption, sorry for making you read a wall of text. By no means am I trying to tell you what to do, just a friendly bit of advice from one internet stranger to another. I have been thoroughly enjoying this build series.

[@kameljoe21]

The drive shaft is likely going to be a standard PTO shaft. Which expands and closes. Think a bar inside a pipe. Which is why its only going to bend one direction I think. Yet I am not sure.

[@anindividual3889]

Yeah, I get that, but it's still pretty easy to stress that front U joint. I have that problem on my baler, and I have been thinking about redoing the hitch.

[@-tere]

Ты Крутой. Translation - you're cool

[@ericmiller2081]

I really love your channel and your work is brilliant. I’m kind of confused about the pivot on the tow bar not aligning with the pivot of the U Joint. Will this not cause unnecessary telescoping of the driveshaft and an added torque stress at the joint? I’m reluctant to ask as you seem to really know your stuff but I’m just wondering about this point.

[@Bigsoot7393]

They are made to telescope mate, won’t matter

[@vuthy0117]

good bro

[@doughale1555]

Doesn’t the tongue pivot point need to be along the same axis as the drive axel pivot point?

[@1983bronc]

From what it looks like to me, he is going to use a PTO shaft that has plenty of travel built into it already. Thus eliminating the need for the pivot point on the same axis of the trive axle.

[@anan0moose]

@@1983bronc The length of the PTO shaft isn't the problem. It's the angle of the U joint when he is negotiating corners.

[@1983bronc]

@@anan0moose with the pto connections being further away from the pivot points the angles of the universal joints should be less.

[@阿湖伯-f8f]

學有專精，工夫了得，比我厲害。

[@aserta]

15:16 You can also cut notches perpendicular to the rotation axis of the bushing (in this image) and then bend a piece of flat bar U shaped, and weld it over. This variant gives extra strength to the whole affair. Source: My brother bought an articulated PTO-ed trailer used inline behind a tractor with a seeder (you use it to put IBCs and other stuff on it if you fertilize and stuff like that), which had that way of holding the bushing, and in an accident, the pin bushing broke weld towards the tow bar, but the strapping held it all together despite the nearly 90 degrees worth of lateral load (it's meant to ride offset to the tractor). When i fixed it, i basically pushed the tow bar against a wall and welded it all back together with a little extra plate under the bushing. It's a really strong design.

[@whodat90]

Shouldn’t the pivot pin be directly under the cross of the U-joint? This would eliminate the shaft changing length as it pivots and allow you to remove the pin without disassembling the carrier bearings.
