Hey guys, this twin I beam is really cool, it's your first time with this suspension design so don't be sad to make mistakes. To eliminate bump steer, your first idea with the crossing linkage was working great because the steering pivot was almost exactly where the suspension pivot was (just like for a double wishbone setup). I really advise you to keep this idea and put a slight bend on the steering linkage (will no affect strengh as much as you'd think), combine this design with a rack and pinion and try using a 5/8" rod below the engine for steering, plenty strong and the steering column will just need two universal joints on the steering wheel side. Really loving this project so far, keep up the good work and stay motivated !!

I have a gokart that had the same problem with the steering being really stiff and really short so I used a old Toyota pickup steering box with gear reduction now I can turn with one finger while sitting still

I love the "we just got rolling stools, no longer on the floor" and the next shot is John on his knees on the floor😂

It's gonna require some re-working, but we'll get it! Hope you're all having a great Monday!

The thing I love about Carandcameras is y’all show when things don’t work but y’all don’t give up on until it’s close to perfect and that y’all show viewers it’s ok to make mistakes when working on projects but don’t give up

Saying that a 2000 model tractor is old makes me feel old

Guys I hope you aren't feeling too disheartened or frustrated, you're not engineers, you're wackjobs with too many go-karts and great ideas, you're doing fucking awesome and I love watching you problem solve, create an invent, much love

I believe that two-man welding technique is called " Trust ".................................lol...................many love, much props

I just put off finishing my b2710 tractor to have lunch and watch your video. To minimize bump steering you want everything on one plane, the angle of the tierods says it would be huge.

The proper welding technique when your buddy holds the steel piece and you air ball a weld is called the " IT'LL BE FINE" technique. 👍💪👍

this is one of my favorite builds so far besides the rat rod wagon

I don't comment often, but it's been a hell of a journey binge watching your builds over the past couple of months since I came across you guys in late February. The ingenuity on display here is awesome.

Congratulations on the tractor, John, I'm in the landscaping business and run those Kubota diesels all the time. those engines will run forever as long as their taken care of, but my advice to you is to not let it sit for long periods of time. With your gokarts, you can let them sit for years and then revive them with a can of carb cleaner, but the diesels aren't that simple. Diesels like that love work, and the best thing for them is simply regular use. If you get a PTO mower for it and use it to mow often, it'll be fine, just don't let it sit for more than a month tops, or you'll have some serious fuel system problems to deal with. Also, on that PTO box you used for steering, don't worry about the torque. the 40 horsepower rating doesn't include safety margins, and even then, the starting torque of a tractor that puts out 40 hp to the PTO is a ton greater than any torque that you guys could put into the steering wheel.

Steering pivots have to be exactly parallel and on the same plain as the suspension arm pivots

I am glad you guys leave your learning moments in your videos. This is how most of us encounter these type issues in real life as we DIY. Learning how to think through, work through and re-evaluate potential solutions is crucial to learn. Unbiased critical thinking is a valuable tool. A couple other favorite channels I watch (looking at you Junkyard Digs and Mustie1) also show their work and I learn right along with you guys (It’s also great fun!). I appreciate the reality in your real-world builds. Great work, I subscribed a while ago, and I watch often!

The first steering mock up was correct. The opposing linkages will need a bend to prevent touching. Also, the 90* gearbox looks to be for a tractor, and a 40 horse tractor will put out a ton of torque. Keep up the good work guys.

As someone with that exact tractor, here are a few things that are a must for that little beast: 1) Proper chevron pattern tires.2) Solid fill AT LEAST the front, liquid-fill the rear. Those small front tires really don't like staying on under load. And yes, solid fill is not cheap ($500 for both sides) but you'll be glad you did it. 2.5) More weight lower, the better since the tractor is narrow. Again, liquid filling the tires help. A big weight box on the 3pt hitch will do wonders for helping with loader work as well. When at capacity the back tires will barely touch the ground so the tractor will strafe instead of turning. Useful in some cases, but scary AF especially since the front axle pivots. A tiller is the best weight since it'd heavy and is a useful tool.3) If you plan on doing dirt work with the bucket, make a ripper hook for the back. I used 1/2 x 3" steel for the blade and 3" pipe for the structure. That little tractor is more powerful than you think when it comes to pulling, provided there's traction, so don't go too thin on the blade. Unfortunately by itself it is way too light to be useful for dirt work so a nice ripper that can go a foot or so underground will do wonders with breaking up the dirt to it can be scooped up. 4) The mower is a bit wider than the loader, so take it off of you're doing some tight work with the bucket. 5) Fuel shut off solenoid will go bad. Replacement is about $100, but you can block off where it goes and run a cable to the shutoff arm on the engine. A cheap and reliable alternative. With that mod the tractor will happily run even with key off, so keep that in mind. 6) Bolts where loader attaches to the frame of the tractor will come loose. Check them from time to time. 7) The tractor can be pull-started. It is difficult AF, but possible for a larger guy. Wrap the rope around the flywheel. It is on the front of the tractor and easy to get to with body off. Use necessary precautions and all that, obviously. 8) Make sure the mower deck shaft is securely on, otherwise you will be buying an oil filter relocation kit after the shaft comes lose and knocks off the trans filter. It is a regular automotive spin on, but the nipple it screws on is made into the transaxle. 9) The transaxle is also the hydraulic pump for steering, loader, and aux hydraulic output on the back (if equipped) so make sure the fluid level stays up. 10) The loader can be easily removed. Lift it up, unfold the stabilizer legs, curl bucket up and lower it on the ground. Wiggle the loader until two big retaining pins can easily slide out, then slowly drive back while "lifting" the bucket until the loader is free of the frame. Shut the tractor off and disconnect the three hydraulic lines. One of the tractor lines has to be looped into the other, but they will only go one way. Having the loader off is useful for mowing. Will probably add more stuff to the tractor video itself, if you do make one and i remember more stuff. Have fun and be safe!

The less angle that you have on your tie rods going up to the steering box, the less bump steer you’ll have. Keeping them as flat as possible allows for up and down motion without the rods changing distance from the main pivot point. I’ve used skewers for kabobs and masking tape to help mock up things like this. Gives you a good understanding of how things will work without wasting materials. You’ll figure it out, good luck!

K.I.S.S. Less is sometimes more. Good luck guys!

I found you guys through the suggested videos 1 year ago still enjoying your videos. your videos are also very informative. I just made a KZfaq channel so I'm definitely doing my research on how to do these rebuilds. Thanks for all your awesome videos. Please keep it up!

I swear Ike is the poster boy for young forever with that surfer dude attitude!

I love the way you guy's show just how much thought and trial and error goes into trying to build a new project. It's not as easy as some channels make it look. If you try to build something , you might have to change things during the build. You guys show more of the real deal . It's looking good .

Thats a magic box guys...............

Hello Issac and John, you guy's should have a bottle of white vinegar for burns. If the skin isn't broken from getting burned you can pour a little bit of vinegar over the fresh burn and it will prevent the blister from forming and will keep the pain to a minimum and in a week or two the skin will sluff off with no soreness what so ever. Apple cider vinegar is best but white vinegar works too.

Y'all done the right thing by stopping and ordering the parts ya need to make it steer as easy as possible Once you're riding it you will be glad ya did It's starting to look really cool guy's 👍✌️

I was just thinking about a jack shaft,mount the steering shaft above the magic box with pillow blocks and with 2 to 1 gears and chain, then straight into the cab and steering wheel. The way the box mounts in your frame looks like a natural. Just a thought, this build is far out, can't wait to see it rip!

I'm gonna have nightmares about bump-steer tonight. Thanks CnC :)

You should take an aerial photo of the property either using a drone or Google maps satellite view and trace out your track layouts. I'm always curious about what the route looks like when you do your time attack runs. Because we can't really see much once you leave the start line. I think that would be really neat. Keep up the amazing work.

Yes video quality and viewing pleasure has noticeably increased

I like it, I also like how you guys arent all freaked out over current events. Low and cool baby. Miss me its all you. Thanks

I have the same model Kubota. Bought new in 2004 (BX2230). I use the heck out of it and never a problem in 16 years.

Steering suggestion , put a sprocket on gear box run a chain to smaller sprocket on stearing column , chain drive gear reduction problem solved . Oh john your suggestion on putting the bend in the links is spot on put the hymes back to where they didnt give bump stear and bend them it will work

Twin I beam suspension has never excelled at its job. Double wishbone is always the best solution. Also this project did not have ackerman's angle in the midsection pivots. Glad to hear you're changing it. :)

Kubota! That has me pumped. Anxious to see you guys clearing paths and making tracks. I hope you'll also continue with the Mini 50 Hondas.

The "Ivan Stewart Little" Trophy Truck is coming along nicely fellas.

This is the most awesome project of ever done, y’all are doing a good job keep it up!!!

the advantage to having the steering handled by two separate points that are linked together (the way you originally had it, instead of linked directly like they are here), is that you can give those two individual steering linkages a little bit of a toe out. that way, when the steering is centered, they both point straight, but when you turn, the inside wheel pivots more. also, the reason that first design had zero bump steer is because the pivots for the steering rods were very close to the pivots for the suspension arms.

I couldn't help but laugh when John called a 2000 Kubota a beater. Granted, I haven't seen it yet, but I've got a '52 Case in my yard that I dug out of my grandpa's shed to replace the engine. Gas powered, 2wd, hand clutch, no power steering. Plus the starter's bad and I can't find the crank, so I have to pull it with the truck to start it. I think you're going to find a lot more uses for your Kubota than you expect. Loader tractors are awesome.

For the least amount of toe change and bump steering, it is necessary to pivot the tie rods where the inner control arms pivot. That way they stay in the same relative position to the control arms no matter what angle they are at. This is easier with a-arms than it is with i-beams. Take some ideas from ford's steering linkages on their i-beam axle trucks.

THIS IS WHY I SUBSCRIBED YEARS AGO BEFORE 100k subs to see project vids like this ! You two guys are my favs. love from the North-East coast!

“Looks like you got it figured out buddy”😅 He keeps getting in your way while your trying to think Isaac

Love the Ernest reference.

Getting closer. Unless you try you never know. Great content!

The rack & pinion should do it if it's got the right gear ratio. You got this guys.

It's called "Tack Teaming" when your buddy holds and you weld👍

"John's over there drillin' some holes and I'm just sitting here thinking"

Hey Issac, this is why i watch your videos , good work guys thanks for the comtent.

Nice drill press, it will help with doing better Fab work. I think that in order to move the channel forward and also for your own personal development you need to get more fab tools. In keeping with your channels theme of using other people’s cast offs and being accessible to home builders you should buy old beat up equipment and fix it. Isaac seems to have a nack for finding old equipment on the cheap so go with it. You really need a mill, lathe, bandsaw, home made welding table and iron worker. All can be found at auctions or shops that are upgrading. A lot of us home builders have shops filled with other people’s cast offs. For the small amount that they are used they work great.

I built a mini buggy for the kids with a 420 predator and atv a arms. I used a john deer tractor steering box. It was slow steering like almost 4 turns lock to lock but the kids had no trouble steering it. Worked out really good with a small go cart steering wheel. I bolted a knob it it when I was rally sporting the buggy

The "magic box" is rated for 389 ft/lbs. PTO spins at 540 rpm, 40 HP at 540 rpm is 389 ft/lbs. The things are made to run tractor-powered augers, I don't think you can break it with your hands.

When your buddy holds it Is called a Dutch rudder 😂

Been watching y'all since the beginning. It's awesome to see that you have your own place and even a tractor!

To get little to no bump steer with that style steering the twin I beam pivot point to knuckle pivot should be equal distance as the idler pivot to knuckle pivot if that makes sense lol progress is looking good guys

Isaac has cars all over the place, make this beast power steering

To eliminate bump steer completely the tie rod has to be the same length as the lower control arm and be parallel so the tie point to the steering box or joint has to be in the same relative position as the lower pivot point of the wheel hub relative to the place where the tie rod connects... it’s hard to explain in words... it’s just that the tie rod length and the lower control arm have to be the same length and parallel in both horizontal an vertical planes. good luck!

"no longer sitting on the floor!" *Immediately cuts to sitting on the floor*

Remember most lifted trucks more than 4.5 inches. Have atleast a 2' drop pitman arm!!!, time to go to some lifted mudd bogg truck research mabey you will have to do a small hydro ram assist set.up for fast response. From a small tractor??!!!!! You should be able to make some real good stuff for the race track out there now maney some nice clean corners, and a small hill and hole would cool nothing deep just some thing fun and a long low table top 😉 can't wait guys looks awesome

This video came at the right time I’m about to start the steering on my build👍

Nice score on that drill press.

well, i'm glad you figured out that you need idler arms ("pivot arms"), but you would've had a better setup if you mounted them longitudinally so the rod ends (heims) would only need to articulate forward/back movement of the traction beams.

Hands down the coolest build you guys have done

It is nice to see the improvements in the shop. :). The trophy truck is looking good. :)

Ike did you pop John in the eye again lol glad to hear about the tractor 20 years ain't old lol

Wow is that crazy I was just watching the video thinking man you should have put rack and pinion in it and hear you mention it right off the bat that's really cool guys please stay safe stay well and as always God bless!!!

your Jim Carry impression to be honest reminded me of Ernest from those old movies... Ernest saves Christmas is one. I also went and looked at my moms old ford with this front end and the tabs that connect the steering linkages is right infront of the pivot points of the swing arms. that could help with bump steer

Love the channel! Also a Kubota BX owner. Its like driving the loader from aliens. Good choice.

Cars and cameras your an awesome channel I watch your channel 3vrey day four like 7 hours

Oh man I'm exited about that Kubota. Time to make some tracks! Careful on those jumps! Kubota is a good brand should serve you well.

This was very tough to watch. I'm screaming inside my head for your guys to look at the steering setups in long travel TTB trucks.

Nice to see both in the intro but love the clips you all are good content creators keep making them an I will keep watching them

Looking awesome guys

It the magic box!!! Only og viewers would understand

Awesome build!

Can't wait to watch after work, been waiting on this guy to come back

Enjoy your videos. Interesting with consistent quality and presentations. 👍

Good to see your trial and error efforts too. That's real life.

awesome vid good to see trophy kart comin together!!!!! itll all work out on the steerin !!!

Finnaly got another vid out for this thank you

love this series

It’s always a great Monday when we get some C&C!

They are so cool to watch

Can't wait for it to be done

You guys say a 2000 model year is a beater and I’m over here with my 1947 Gibson still working hard like🤷🏻‍♂️....😂😂

When you shortened the tie rods and made them more than 5%-10% different lengths than the half axles, bump steer was inevitable. Isaac, you've obviously got a lot from the modified twin i beam trucks- they led you to a design with tie rods equal or nearly equal to the length of the half axles. NOw, put a tie rod, close to the length of the half axle, on to the right side wheel- visualize that free end controlled by the arm of the magic box, mounted to where it's arm centers on the tie rod end with the right tire straight ahead. Install the other tie rod, the same length as the right one, onto the left steering arm. Hold that tie rod free end where it falls on the right steering arm tie rod- right there you need put a bolt and joint so that the right tie rod moving will then move the left tie rod. There will be some bump at the +4 inches and -4 inches of travel, but it won't be much and it will largely be when the front wheels are unloaded. Mock it up and see it your self- PVC would be fast and cheap. A traditional recirculating ball type steering box would be easier to adapt to this- a small one if possible.John, shortening the tie rods will amplify the bump steer effect.

you have done it again your the best

That flat bar needs some bosses.

Keep up the good work guys

Looks good with the tires and spacers. I think it's kinda looking like one of those Baja buggies, maybe a little different cockpit.

Its going to be sick when its finished!!!

Cool project guys, good job👍

Rack and pinion probably will cause more problems than it solves. Your left drag link pivot will line up with the right suspension pivot and vice versa. Unless you mount it behind the axle centerline so right turn is left and left turn is right then and tie the draglinks to the far sides of the rack not the close ones. Lol very confusing to try an type out but im interested to see what you come up with. I like the steering quickener idea

Junkyard 70s pinto or late 70s to early 80s ford thunderbird/mercury cougar rack and pinion. Its amazing how many applications they work for.

And I was waiting to see the “new” tractor. Oh whoa is me.

I remember the discovery of the magic box with the rat rod wagon didn't even think about the direction or rotation before buying it lol

Can’t wait till this is done

Yay I found Part 8 or at least I think I did ... Y'all really need to edit the names and do a playlist. :D

nice work guys

Can’t wait for the first test drive

Guys should look for a steering box from a chevy 1500, s10 or blazer that has the pitman arm. Mount it to one side so you can run the steering shaft on the side of the engine.

Best way to minimize bump steer is to make sure you suspension pivot points match your steering pivot points. Your tie rod should also be a similar length to your control arm.
