Last video you guys where asking about the seats I'm using for this project so here is a link for them on amazon
a.co/d/hvVlpAu
Glad you mentioned those T90 Jeep Transmissions been trying to figure out something for a drive train in a creation I want to build... found 3 on ebay under 800 bucks with the twin stick transfercase
If you need parts for this transmission you can get literally any part from Kaiser willys last time I checked
Their parts are more expensive but higher quality.
Sorry but no way the other cart has 18 to 19 inch's of suspension travel you would need 19 inches or more of ground clearance in order to have that much suspension travel...
I'm thinking about getting into building karts where can I learn how to build karts
I was super hyped about this build all the way up till you started placing the bars for the sides and roof and then I realized you were going to build a high top conversion van. You've got the roof bars a foot+ over your head to make room to get in because you've made the side bars tall enough to make it a 2 story interior.
Lay your seat backs down some, drop the side bar height and roof line way down. That will help 2 things, 1st will be top heavy issues and 2nd will be support for your spine. Taking a beating sitting upright is the worst thing you can do to your body. That's why all off-road builds have a short roof and a leaned back drivers seat. It keeps you from jamming your spine together if you hit hard bumps/jumps.
One thing he could do is go out to any 70-95 pickup and measure seat to door window height those are the years that you can role the window down and rest your arm on the window frame comfortably back before ac was standardized to vehicles and often trucks weren't optioned with ac... Once ac was standardized the window heights went up as rolling down the window was thought to only be necessary for drive thru windows as well as to better retain an occupant in a side impact
lmaooo hightop conversion fan
Nice build. As for the suspension travel, no one ever considers rotating the outer ball joints 90 degrees. This will give you infinite vertical articulation. Imagine the outer ball joints in the smae orientation as the inner ball joints. You don't need to spin the tire around 360 degrees. So why have the most freedom of motion dedicated to the wheel turn radius? Use high offset bushings and next size up if you want more wheel turn, but you probably don't need it.
You can even just do it for the upper one in this case and get the travel he needs
Your question intrigues me.
I've looked at my catalogues and manuals and it turns out ball joints are meant for load parallel to their axis (vertical load, vertical joint).
Surely it's not a matter of the bolt being weak... a big fat high resistance bolt is several times stronger than the sheet metal it's bolted to.
Vehicles and cars are the same: I really can't understand why ball joints are not used in the other direction.
@@Morannar well actual ball joints are different, these are heim joints. With a heim joint, you can use a through bolt grade 8 and when supported on both sides it is way strong enough for this light vehicle.
@@TheChicagOP might as well do both. The inboard joints are mounted with horizontal bolts, why not do the out board joints the same?
LIMITED TO CV AXLES OPERATING ANGLE REGARDLESS, AND THE STEERING ANGLE LIMITED TO MATCH SO YOU DONT OVER ANGLE THE CVS
Dude, your vids are awesome. Seriously, from your fabrication talents, to your out of the box ideas and solutions, to your incredible editing and shooting, I'm truly impressed everytime I see one of your videos
Agreed. I've been watching this kid since he started. If you go back and look through the progression of projects you can see the growth... It's impressive.
He makes me feel like a lazy piece of crap. I can't complain about lack of tools and stuff... The tools I don't have I know I can make. It's more motivation than anything else...
Looking forward to seeing this jumping and climbing in 2023 but I'm also looking for my own welder and stuff to start building stuff myself because watching your videos gives me so much motivation to build something.... It's just cool to see you build these awesome vehicles by yourself and that's most likely what I'll be doing, I think I'd have better success doing it alone. Thanks for the video and I can't wait to see what you build in 2023.... 😁👍
That demonstration of the suspension travel was so smooth. Amazing work.
Chris,
Firstly, HAPPY NEW YEAR!!!
Secondly, I know you seem to prefer building your projects with chain drive systems, but I hope you create a purely shaft driven 4wd project some time in the future. Heck, I would LOVE to see you create something similar to this or even convert this project to a shaft drive rather than chain drive system...
Maybe there's a reason you don't like shaft drives or something, but if you do, I'd love to know the reason
G
Dude that's actually a pretty ingenious way to hold tubing in place for fabrication. Thanks for the great idea.
I watched the cbr 1000 build twice. Once myself and once with my dad. Its mesmerizing what this guy is able to do. Love the content. Dont change a thing.
I have that exact same angle finder. I absolutely love it. I use mine for everything. Scratch building model car parts. Building things with wood and metal. It's so handy.
hearing u say how cold it is then imediatly seeing you on your knees on that frozen floor ... you are a trooper !!! keep up the great work man LOVE LOVE LOVE your stuff
Love watching your videos of you building toy's for yourself right from scratch.
Right from the bottom and up.
Keep up with the awesome work 👏 ✌️
Thanks for filming Chris! 👍😁
thanks for telling us about the t-90 tramission, most likely will use them for some of my projects so thanks.
great video yet again, im loving this whole project.
Браво! Ты - настоящий мастер. Приятно смотреть на работу!
That was brilliant you can create these mad vehicles from scratch but struggled measuring the suspension travel lol. Love the content and keep it up
Your absolutely knocking this thing out! Congrats
it took me all summer to make a minibike frame...and you do this stuff...just amazing
Amazing work - especially trying to think, build, design, film, etc. in such low temperatures. 👍👍
Been loving this build series! You show some very good techniques in your videos!
Here is what is going to happen, as ive said 3 other times on this project, you will complete this, it will look amazing. Youll ride it around your neighborhood and be amazed, then take it to one of those off road parks and overheat it and/or smoke the clutch trying to push that 1 ton vehicle and LARGE tires when that bike engine was meant to push a 300 or 400 lb bike. Wish you would consider using honda k motors in these bigger projects. that being said if you want more visibility out front try building your front shocks like an indy car with belcranks and run the shocks in the middle in line with the chassis.. That would be different and cool to see
The hyabusa weighed almost 800 pounds, it’s a big bike and could support over 400lbz of riders
@@relentlessgaming4453 OP is right. 800lbs is closer to 400lbs than it is to 2000 lbs.
And the Busa turns much lighter tires, which is another way of saying much lighter tires exert forces on the drivetrain, those big tires are exponentially harder to turn
@@relentlessgaming4453 a hyabusa is nearer 600 pounds.
@@relentlessgaming4453 hayabusa is 586lbs. but although it is a very capable engine it's the size of the clutch and lack of torque that limits it ability in a heavy vehicle not to mention the extra rolling resistance caused by the much larger tyres and being 4wd
That engine is way powerful enough to push that vehicle around. He Has always said He enjoyes doing Things differet than other people. I mean He is making it chain drive!
I cant believe how many subscribers you have now!!! When i started watching you, you barely had any and now look at you! You deserve it, brother!
Man, I love the background music...it has a very 90s alternative feel to it
Happy new year my dude! You are literally a freaking genius 👏
Couldn’t wait to get off work once I got the alert. Only way to start the new year off. 😎 because Rather B Welding is one of the best fabricator on UA-cam, no fancy lathe or millers just straight old fashioned fabrications.
Great video as always, have a wonderful new year building.
Dude I am so glad I subscribed to your channel. This project is right up my alley. I am building something similar and you’re really helping me out with mock-up and planning. 🤘🏼cheers
I admire your work, happy new year!
Awesome work man!!! Love watching these vids
SICK!
Nice build! Like always, interesting! Thanks
Nice work as usual 👌 from Canada 🇨🇦
Man 4wd is wild. Your on par with grind hard plumbing
Looking good Chris.
Love the vids bro been here sinc the beginning . Keep it up
I love this build!
Glad i stumbled upon the series, bummed that the latest part was released 2 days ago... now i have to wait :) For me, as electrical engineer, this is all new territory. Ive for a while wondered how structures like this was built, the thought process, tools and tricks. Might invest in a welder and start with learning that, maybe I can make myself some sort of toy in the future. Good video.
Love your builds and your unhealthy liking of chain drive. Subbed!
You can always put in pins to be able to remove that side bar to allow access into the vehicle.
Additional safety feature you might consider is the window nets to help keep arms and hands inside the enclosed area as people have a tendency to lose control of their arms as the vehicle rolls over.
Just a precautionary addition since you are increasing the speeds at which your traveling, and better to be safe than sorry I believe.
PS
You have the easiest calculator in the world in your hands.
Simply line up the end of the tape measure with the number that you want to add or subtract from.
Then say you want to add 6" to say 31", just slide the tape end past 31" until you get the 6" mark inline and look at the end of the tape measure.
Should equal to the total of the two combined numbers. Just the opposite to subtract, but instead of moving the tape forward past the whole number.
Simply look to see where the number you are taking away lines up on the tape measure, and that's your correct answer.
Basically using the tape measure as a old fashion slide rule, something akin to what the Chinese used when they invented mathematics counting devices.
Dont bother. this dude cant even count to 12 wtf rly and you never measure "full" travel as the "full" travel lol. in those ENDPOINT angles you will immediately destroy youre cv or something else when it binds up. one needs atleast 2 inches safe margin on top and bottom travel to not bind the axles.. if you need more travel you need longer a arms and will end up with a wider vehicle..
You show the marking of genius some times. I’m not kidding. Ability to adapt is most important. 25:51
Always enjoy when you’ve got the next video sure bets regular TV and I learn from you which I won’t use cause I’m Retired and enjoy your content keep up the great work
Awesome bud keep up the good work can’t wait to see it finished 😄
Guys i m very short of word to say it's amazing or beyond amazing i learned a lot from you wel done
The craziest part about this whole build is that this dude can’t do simple addition and subtraction. But decides to build a death trap 😂. I love it!!
I was thinking the same thing
Great video as always, and awesome work. I do want to comment on the front suspension and shock set up though... I love how you build everything !
Though it may seem wonderful that you only have 5" of shock travel and 12" of wheel travel, this means you have over a 2 to one ratio. This isn't necessarily bad, but on this type of vehicle it isn't good. For example, if you have 12" travel and 12" shock you have a one to one ratio and the load that is on the wheel is the same as what it is on the shock. If you have 12" travel and 6" shock, your spring rate and damper take twice as much load. In a long travel vehicle the suspension is going to take a thrashing. The spring needs to be twice as stiff to support the vehicle, so the damper also needs to resist twice as hard to stop bouncing... this means the shocks get really really hot. They will work worse as the day goes on, as they get hot, and they will wear out much quicker. It is also much harder to tune the suspension. All of this to say, that if you're going to use this ratio, make sure that you have really good shocks. Lots of trophy trucks will have two dampers and one spring, and at least one damper will have a piggyback reservoir to try to keep the oil cool.
it seems to me like you should consider changing the angle of the heim joints in the control arms so that you can maximize travel. You can do this without bending anything. It's going to be a pain, but the end of the hemi joint doesn't have to go into the control arm... Meaning you can notch the end of the control arm at the desired angle and weld the threaded insert on 👍
this thing is seriously awesome!
Happy new year and great video as usual
Hi! Im new to the channel and i love the hands on approach 👍
Since i've studied some vehicle dynamics and the impact it has on the handling of the car, i would really recommend spending a few hours reading up on camber, castor, kingpin, ackerman and bumpsteer and the dynamic effects on the vehicle of that since that is bound by the position of the joints. It is true what you say about being able to adjust the camber etc afterwards, but only in a static case. You cant adjust the angle for the full range of motion the wheel makes. Maybe you have already considered this but if you havent, spend a few hours on google (or keep in touch and i might be able to send some recommendations) so that you dont have to relocate the joints later and find that the shock/spring is not fitting anymore. And by the way, if the travel at the spring is only half of what the wheel is, the force in to the spring (its joints, attachment points etc) will be doubled of that at the wheel.
Hope to see more on the electric dirtbike soon, keep up the good work 👍
On most long travel setups you'd run uniballs vertically on the spindles. You'd gain a lot more travel in the arms. For the axles you can go in and make some clearance to gain a bit more before they bind.
Awesome work mate. Im also building a new toy here in new Zealand your videos help heaps
Commenting while watching.. Happy New Years 🎉BTW.. but that holder was genius!,
FWIW,, a Muncey 4 speed is aluminum cased and so much lighter than the toploader.. it also uses shifter rods so easy to move the shifter around. Great channel.. :)
I watched almost the while thing and realized he's welding in a wood floor shed. Brave man.
Hey man,
greetings from germany :) I really enjoy your videos everey sunday. I just wanted to say thanks for your awesome content. Keep up the good work! :) I am really looking forward to see this project coming together.
As usual like what I’m seeing 👍🏻 didn’t think it got that cold in your area, stay warm and happy new year 🎉
Happy New Years bro, cant wait to see this thing when its done! Also really want to see the electric dirt bike rip on a trail, makes me want to build one every time I see that thing!
Brr 🥶
Tweek (bend the upper a arm to clear the joint bind)
One good thing about working in a cold shop is, no big ass spiders crawling around.
Maravilha o projeto amigo!!!
Feliz Ano Novo a todo com muita saúde e paz e realizações!!!
You are the man. That thing is looking great !
That's a cool tool you made for angles 😎
the best part ¨I can´t do that kinda math¨
by the way, great work there man. looks good.
Chris, make some doors for it. That is looking to be a large project and doors would make it so much easier to get in and out.
Great project man. I still wanna see you build something capable and road legal though!
thanks for the videos
awsome.. love shop briefs..
Projeto extraordinário!
No wonder you’d rather b welding u have some pretty good fab skills keep up the good work man ur killing it
The golden ratio of 1 to 1.618 will almost always let you fabricate out of thin air but finish with a project that is pleasing to the eye.
Lovin' It !!
Try mounting top A-arm brackets to the top of the tube and bottom A-arm brackets to the bottom of the tube. You want to get the driveshafts as parallel to the ground as possible at normal ride height with you in the vehicle. You have very little compression at the moment with most of the suspension travel on droop at that driveshaft angle.
I've gotta say I really would like to see what you could build with all automotive parts. Axles, motor,transmission ect. Bet you could build and bad ass crawler!
Nice work,
I am a follower from Morocco, you are really very cool, thank you very much
If you put a bend in the a arms where the Himes joint is limited you won’t have to change the mounts on the hubs. I love the project so far.
Excellent ! ☮️
Lovin the videos... The last time I saw a trophy truck with a low range was... well, never. HEHE. Keep it up, it'll be nice to see someone be able to ride with ya.
Good job 👍✌️
Use a fan to circulate the warm air :) or maybe insulate the door a touch by adding plywood to the inside to have trapped air? As climate changes and the years pass, we must adapt and overcome! A good sentiment to the years ahead! Cheers and all the best to your new year!
😂
I Iike to be like you at another life. In this one, I feal like I already messed up and won't be able to do a change. You are awesome!
Never to late. Don't ever convince yourself of that. Change happens now if you want it do it. If you don't try you will regret it. Not trying is failure. Trying and not succeeding is learning.
You need to build the spindles with your heim joints vertical. That will give you unlimited travel. The only limitations would be the axle. Make some center mounted a arms to get more travel.
Our Polaris pro r has 22” of wheel travel.
Very good job bro 👍
First, your vids are getting really good! Second, what you need are called high misalignment spacers, designed for heim joints
Nice build! You really should put a diff in the front! Doing turns in this thing will be difficult.
Super impressed with this build. Stoked seeing your heading for 100k subs super fast. Happy New Year 2023... r B w
You want more than 12” of wheel travel if your calling a trophy truck type build. Aim for half the tire ratio 30 tire 15” min. Bend you links at the ends to center your rod ends to get more up travel or rotate them 90 deg. Less turn but more travel up and down. Love your builds.
Very nice, what size swing arm joints are they, balls joints.
I enjoy that u complete these crazy projects with zero CAD edit: just got to 15:40 but still no cad for where the engine goes, frame design, drive, ect
turn the heim joints all vertical and use bump stops for the up travel and limit straps for down travel
it is awesome
Not sure if it would be helpful or not but maybe setting up a laser line to get everything lined up correctly 🤷🏼
Happy new year
new in box rebuilt and painted those T90s are only $686 right now 😱...definitely gonna have to get one for my r1 engine project. those reverse boxes are ridiculously overpriced
Biggest thing with shock travel. Build the entire thing at full bump, then limit the down travel with the straps. With many of your previous builds you run much too large of shocks which case the chassis' to be taller than required and most of the shock travel is unused
exactly 100% correct. love the creativity from this guy but sometimes it just takes a bit of researching and you will end up with a way better build. building from bump height is the best thing to do when building anything.
Definitely going to need a skid-plate
You need some doors 😅 always enjoy your content and the work you do ever thought about getting a Loan and build you a great building the way you want it plus you’d have heat and 220 that you wouldn’t have to run lonnnng 220 cords Have a great new year
Which grade of metal tubing do you use?
You should swell the middle bar out bring it out about 8 in maybe 6 in and that way it is a little bit more protection for your arm and shoulder on the exterior and it will give the body a little bit better lines
Flip your Heim joints sideways and use the pivot of the Heim for steering. Then you have unlimited up and down travel, or at least whatever your CV joints and tie rods can handle.
i would consider modifying /remake the front upright to change the joint movement and would also consider the suggestion of rotating thejoint 90deg so its onlyyour steering thats limited.
also just to help i would try and mount the damper position as far outon the wishbone as possible due to over heating the damper on rough terrain as the volume of oil will be small plus your damping will be greatly improved.
also on the damper a good starting point for the damper angle is 30-35deg from vertical.
drive shafts looks spot on setup 👍
Can the spool be taken out for maintenance ?
really cool project and cant wait to see the finished truck.
2023 Should be interesting, Happy New Year Y'all.
