S3 E39 we custom build drive axles for the kubota d722 diesel powered Honda Insight. 

Simple heater core in a box with a fan should be just fine for the heat. No need to overcomplicate it.

This show to me at 50 is like Saturday morning cartoons were to me at 5. Great work!

8:47 "It's not until the stupercharger or turbo kicks in" I hope one of the experiments in this series is turning that "or" into an "and." Compound stuper-turbo charged kubota would be a sight.

Eggs bacon and toast on the go. Perfect pairing for a Cantina episode!

I ran welded front axles in the front of my older racecar for years, 600hp blown Stroked LS AWD without a single failure on Dirt or Tarmac, you've got this!

It'll be interesting to see if this Insight gets as good a fuel economy as they did originally, given this generation was a literal hypermiler car versus the later prius-like hybrid thing that just wasn't the same... :P

Those Saturns were actually great little cars, I had 3 of them over the years and put 335,000+ miles on one. The wheel bearings seemed to be junk and would go out religiously every 100,000 miles and if you lived in a cold climate you all but had to cover the entire radiator with cardboard if you were gonna build any heat in the cab. But other than that I loved them, their 5 speed gearbox was always a pleasure to drive, I never used the clutch 👍

I'm impressed with how true that welded axle runs, good work to you and the welding shop.

Super excited to see mpg numbers in the Honda!

Awesome awesome! I’m excited to see this car back on the road!!! I really love this little car! It’s very iconic 👏👏👏

The diesel finally returns.

The nub at the splice is often called a spigot. Commonly used on heavy equipment repairs.

Man, I am addicted to your channel. I dont think people realize the incredible amount of time you have in these projects. Thank you and dint change a thing. PS- Pay no attention to the beddwetting experts that knock everything you do. Most are still living under mommys skirt and have no idea what they are talking about.

Jimbo's Datsun The car that hasn't a smol engine... yet But i can see it as a future project: SMALL ALTIMA ENERGY!

my 3 year old is dancing around the living room to your outtro song. so funny! this is going to be such a cool little build

Just goes to show that you don’t need billet and chrome parts for a project to work! Great video

woah. hot off the freaking press. 10:00 AM CST sharp. so cool. i love this car.

you could probably run a motorcycle radiator as a heater core. Might even be able to swing a transmission or engine oil cooler. 12V PC fans are also fairly affordable and some even have speed control if you wanna get fancy. Love your stuff! makes my Sunday morning :D

Great work on the axles, Jimbo. I was thinking that instead of turning down the Honda side axle, I would have considered a sleeve with the two required inside diameters, and then plug weld it to the shafts. Likely strong enough for the Kubota. Also makes setting the required length much easier.

Far back in the mists of time, I replaced the heater core in a Hilux with a 12V electric unit. It was ok, but you really appreciate how much heat a big combustion motor kicks out!

Thank you for bringing us on the adventure

I would like to see a vapor car. If you put gasoline in a sealed container, add heat, and a full intake to the fuel tank, heat the entire intake all the way to the engine, you get an engine that cracks the fuel just like the oil refineries do with excellent fuel economy. Crude oil is boiled or distilled into lighter fuels when it's processed. Well the same thing happens under full vacuum and heat. Great video, as always I like ,share, and subscribe.

The countdown for next week begins now!

Another great visit to your garage.

I love it, I wake up Sundays, sit at my computer, load up my work and start watching you working.

I learned something new about cv axles today.

Roadkill got away with welded axles on Datsun 240 that made about 280 HP. Between the nature of the project and the fact that you had pros take care of it, you shouldn't have a problem. I look forward to that diesel rattling to life again.

It's a good week when we get some more Robot Cantina.

Thanks for all the work you do off camera to make these videos.

Always love me some custom axles. The internet gets real upset.

I waited so long for the Kubota engine car episodes... I think you did a really good job on the last Kubota engine Saturn. I m more interested on the fuel consumption side of this engine.. the Saturn episodes fuel consumption was outstanding.. it's even more fuel efficient than my scooter 😂. Keep up the good work

Let’s roll!!!

« Arbre homocinétique » ! No video without some French. I like that! J’adore ça ! 🇫🇷♥️🇫🇷

8:26 "Before some of you freak out, It'd be helpful if you actually did some research". Jumbo has had enough of our BS. 🤣 Great work cant wait for next week!

I’ve done it this Way. I’ve also just sleeved them and rosette welded. We always tig them where I worked. We cut the sleeve at a 45° angle with the angles opposite of each other. It gives substantially more contact area for the welding, and we did not weld the shafts directly to each other. The way you did it is very strong.

Outstanding run-out number on the hybrid axles, it shows the value of your planning and preparation. Nicely done.

Thanks jimbo I like what your doing

Awesome to see this project continuing to move forward. I was really happy to see the runoff after the axle welds being under a hundredth. And I'm happy to see you reusing the Honda fuel tank, those diesel fumes are nasty and it always made me feel some kind of way hearing you describe having to put up with the fumes while test driving. 🎉

There are tons of different heater boxes you can buy and even plumb into existing vents if the car still has them. I love your videos man, keep it up 👍

Thank u soo much for this Series, u inspired me to do the same swap in my Trabant 601! The only thing im really struggling with is the Adapter to the Original Gearbox, and to find a smaller Oil Pan because its really rare here (or expensive) But thank u soo much! Ur Series Helped me really really much! Greetings from Germany!

That's crazy. I had no idea a lot of aftermarket axles weren't serviceable. I hate throwaway parts!

Oh yeah more excitement today and a change of venue. Lots of fun. Hope you get it running soon.. CYA next week

Thank you for being my neighbor!

The perfect video for the end of the weekend

I have Renault Safrane V6 24V 190hp swapped from AT to MT with custom "homemade" axles. And it works fine. Only joints need service every 3-4 years. It works for 11 years. It drives same like my another V6 Safrane with AT. :D

I always appreciate the Insight this channel provides. 😂 Seriously tho the channel is a brilliant combination of entertainment and education. Keep it up Jimbo!

I live in North Dakota. You definitely need a heated in your beater. LOL I agree with the others. Keep it simple/ Heater core with a fan in some sort of enclosure would work just fine in that little car.

Incredible backyard engineering for that axle solution! That's the stuff I like to see. Welding that in 40 passes and a trip on the lathe would have been doable, but I don't blame you for taking it to a shop one bit. Nothing like sorting out a high stress but crucial rotating assembly, thinking you've got it down to micron perfection, then feeling it shake itself to death from being out of spec by a whisker on the maiden voyage. Ah, the circle of recurring project vehicles grows evermore! Never a dull moment. 😁👍 Add: Just for laughs, I would consider a little wood burner stove for your winter heat. Heck, if you want to get _real_ whimsical, wood vapor combustion for fuel and heat via thermal transmission pipe (guess you could call it an exhaust pipe over the transmission tunnel) would be comical.

If you run the diesel on WVO (waste vegetable oil) no worries about fuel stink - smells like fries or tempura. The wvo conversion would be a nice addition to this cool project.

I have really been looking forward to the Kubota swap into tha Honda Insight, thanks for sharing 👍.

Thats a serious weld 😁

I laughed when I saw the Grassroots Motorsports sticker on the welder. This channel had GRM vibes for sure.

You did a great job of building the axels. I've seen a lot of them modified, and your work looks top notch.

You can get some pretty cheap heater cores with 12v fans attached.

some anti fog window treatment for the windshield would help with the basic heater core concept in the winter.

got to admit a coal rollin Insight is pretty funny🤣

Sunday morning funnies with Robot Cantina and a cuppa…

Seeing Yoder really makes me want some Carriage Crossing.

Great job Jimbo. Solid work Sir

Your having way too much fun playing with that tripod axle.

A cheap option for heat could be one of those knock-off Webasto or Eberspächer Diesel heaters off the jungle side. That would keep you nice and toasty in that little car.

Curious if the balance on the axle is a concern? Enjoy this channel a lot. It is part of my Sunday ritual .

I think the best part of this is that when its all done, the car will probably only be slightly slower than a stock insight with no IMA. That 1.0 3cyl makes 50hp on its best day!

Sounds like another visit from 100 percent Jake with some spare HVAC parts for the Insight😂

Thank you.👍

Up top from Jamaica.. love your stuff

Thanks, another very informative program!😊

This is my Favorite project on Robot Cantina

10:30 I was expecting you to jump into the Renault 10 and drive there! 😉

For heaters, there's some good kits for side bys that come with speed control, and usually a simple door for windshield or floor and some ducting. Work great for old farm trucks and hot rods.

Yay! Kuboda!

Honda insight enthusiast here, the original gasoline engine was definitely not known for snapping axles. It happens occasionally, almost always when people are being dumb and spinning the tires in second gear with full electric motor assist. Wheel hop will snap axles, but you almost have to be trying.

8:00 looks like Jimbo has made himself a sweet Lightsaber 🤓

Love the content and love the editing, it’s just seamless from beginning to end. Informative and so easy to watch, Thankyou !

It’s fine, everything is fine 😂😂😂. I love your videos and your attitude.

Great work Jimbo! Another satisfying Sunday video. Eager to see you bring the thundering sound of a diesel to this buggy.

10:37 You got your driveshaft welded by Yoder?? Ooh, the force will be strong in this one😁

Amazing job on those axels

They make universal heater corew with fans and vents like the ones you'd find as an option in an old Suburban. Might work well in a car that size with minimal effort.

A 3 bang pot diesel in winter? Are you sure you'll get heat out of that? 🤣 I lked this video so much I hit the button 3 times!

Jegs or summit sells a defroster unit for race cars. It’s basically a self contained heater. Run power and coolant to it. That’s it.

I remember when the 1st VW Polo diesel came out, it had to have an electric heater because the engine didn't make enough heat to heat a water heated heater core - lol -.

Aww man I got sidetracked and I'm late. Coffee and Cantina, here we goooooo! 😎

I love the Grassroots Motorsports decal!

Sweet!!

Flex-a-lite Mojave heater is a nice kit comes with everything you need to put a heater in anything that’s liquid cooled

Thanks Jimbo! Your videos always help make my day! 👍🏼

I bet when You add heat to the car the Kubota won´t make enough heat in the first place. Seems like a good plan to add valving to the main rad to limit or shut it off if needed. But with all ironed out I see this becoming Jimbo´s daily!

Great to see a new video on the diesel Insight. If you are going to drive it in the winter you also need to figure out something to defog the windshield. Driving with a fogged up windshield is almost impossible.

so for axles that can't come apart with the tool, you can still over-extend the angle on the joint and pop the balls out one by one, and then disassemble it that way. Once you have that, the inner CV part can come off the axle. (there's most likely a C clip in there) A friend of mine with way more patience than me figured that out. :)

An old tractor or combine would be an easy place to get a heater box squirrel cage fan set up. Old school bus floor heater as well.

Nice to see a "new" project! I started watching with the Renault videos. Maybe for a heater in the Insight, just go with a 12v power supply and portable 12v electric heater. ? Also, I think it would be cool on the Renault to put a matching Predator engine and drivetrain in the front with a front wheel drive setup (maybe from a Saturn?) for all wheel drive. See what that does for performance. Could be really useful in those Kansas winters too!

Finally a break from cvt that keep breaking and carburetors.

Can't start my Sundays without coffee, and RobotCantina. Great episode, Jimbo.

For the heating I vote for a plastic tub as a cooling water sump at the feet of the driver seat. Dunk your feet in when you are cold.

You could get wild with the heater. 240 or 740 volvo heater cores pump out enough heat to bake cookies. Sadly though, a small diesel engine would most likely get too cold to be efficient with one of those heater cores. I suppose you COULD wrap copper tubing around the exhaust some where, and whip up a stand alone heating system. While it would be almost instant heat in the winter, it would also add a pile of complexity to the over all build. Chinese diesel heater ? 🤷 Anyway, I love your builds, even the ones that dont quite live up to your expectations. Interesting and informative every time.

Not only is the content extremely good but theres also so much to learn. See ya next week Jimbo

I would love this car to be your “going to town rig “ that leval of trust in the car would be cool

Excellent ! Jim.

I've took apart a lot of Honda axles, it's crude but if you angle the end to the max and hit it with a hammer it will eventually come off. Done it many time track side when I needed to change.
