Engine Sprocket Extension... Mini 4WD Trophy Truck Project - Part 8

With this project we are taking chain drive to the next level and seeing how well it works with 4WD and large 32" tires. I've had great success with the chain drive setup on the CBR1000 buggy so with this project I want to build it again but this time we are making it 4WD with big 32" tires and its a two seater. we are using a T90 transmission as a transfer case to give us high/medium/low range and reverse.

Those engine mounts are a work of art! Much better than plate steel 🙂

[@musicauthority7828]

I like to use pillow blocks whenever I can. because they are extremely strong and adjustable and in most cases grease able. I just I would mention that. and I also thought I would mention. your choice of music for your videos. is hands down the best on YT for sure. keep up the great work.

[@larrydavidson3402]

Excellent job on the motor mounts and as I see it the whole build is a work of art.

[@wags9777]

The metal you were tying to drill was Probably work hardening. Best option there is to keep coolant on it and constant pressure until you're through

[@JosefinaSwift]

If you are doing your best, you will not have to worry about failure.

[@CncObsession]

Generally it is better to cut towards the chuck. Also if tapping, use Tap Magic. It is a game changer. The metal you were turning is work hardening. Slow down, use lube and sharp tools.

[@joker4206987]

Lmao 🤣 dude go watch my KZbin lol

[@GodschildinNC]

Great work, keep on building like this and we will keep on watching!

[@asayoasayo5746]

I truly appreciate and enjoy your channel. I'm always looking forward for the next video. I love your work. Great job.

[@johnbest4320]

Starting to take shape love that your using stuff from the cbr 1000 build that just worked flawlessly & implementing here your metal work & welding is marvellous I am getting excited to see the Finnished product this shoukd be amazing have a nice week mate 👊💨

[@davestevens4263]

Those engine mounts are sweet . Your skills just blows me away every time . & I’m a part time fabricator. Your right there with Ethan at ghpc ! This build is getting exciting

[@MarkSmith-wu8rh]

It’s crazy how far you’ve come, I remember watching one of your first builds it was a tiny four wheeler you made in school , now you’re building massive buggies !! Keep it up 👍🏼

[@sourdonkeyjuice]

Those engine mounts are awesome! Great work on this project!

[@nicholasthurman2266]

I would’ve done the engine mounts differently but your work is what make you different. I’m the kinda person that will tell you, if you can build it, I can build it 💯

[@jimhowell4937]

Chains are very strong but have to admit riding in that at speed would be terrifying with that much mass rotating around my limb’s. Love it!

[@sophakpeth4346]

Of all the builds I follow on YT, I look forward to this one the most. Great job as always. You’re truly inspiring!

[@supadeluxe]

You've done a lot of good work so far BUT, by far, those engine mounts are my favourite parts!

[@BenNawrath]

Round stock for the engine mounts definitely looks awesome.

[@islandlife9127]

You definitely have some mad skills. The quality of your builds away impress.

[@kinkong1961]

as a long-time viewer of your channel I still can't get over the amount of skill you have attained it is incredible to watch and so entertaining for mech heads like us who have done similar projects in the past I used to build off-road land rovers I mean lighten them up fit diff locks in the axles lift the suspension and increase the angle uprate the engines I used 3-litre ford v6 and ford v8 5-litre engines the 5 was the best the old mustang engine and they sound fantastic and there are plenty of parts for them to uprate them even in the UK(ENGLAND) plus fitting lighting snorkels bigger tyres uprating the drive system like drive shafts as they were prone to break we used range rover axles and shafts from the states US as they were the best in strength and then have fun trying to get them stuck in impossible positions but still get out without using the winch those were the days. so I love watching you revive it all for me and invent some new ways for the drive system like the one before using the jackshaft as the swinging arm is genius so impressed so all the best Chris from John from Rugby UK.OH ps and CONGRATS ON 600.000 subs mate you should be on the millions by now with your level of skill but nothing stranger than folk.

[@ABCustoms]

21:27 I would definitely put the zooming thing for the lathe in an insulated box outside. That thing drives you crazy!

[@darrinbosley1728]

I really have come to enjoy watching you work. I also enjoy seeing a small look at you thought process. I have taken the time to watch almost all of your past videos. You have really grown into a very well rounded engineer, and fabricator. Thank you for sharing through your videos.

[@nordgrinder6119]

Happy 600k! Great work, Chris! We absolutely love your content.

[@hrsey71]

you should name this project "chain reaction" seems fitting since theres a million chains on it

[@chrismullett6072]

13:03 had me in tears, glad you put that in. Your work is inspirational, cheers from Australia.

[@worldsbestwatcher3735]

Great decision on the motor mounts. Awesome job. Your skills have come a long way since I first started watching you. You were just teething on 1/2" bolts. Good luck and thanks for not editing out the little bloopers. 👍

[@theDirtbikeninja]

WARNING!!!!!!!! You'll need to re-engineer the way you're attaching that shaft extension to your engines output shaft. Man, that extension is SICK!!!! However, by applying any side load whatsoever to that output shaft is going to do some serious damage really quickly. I've seen another comment here about this, but this particular issue cannot be missed. You were correct in explaining how the sprocket is held on the shaft with a bolt. Now, imagine backing off the pressure the secondary bearing and its mounting plate are putting on the output shaft JUST enough so as not to give the extension any side-to-side play, but keeping it in place. Essentially putting up a wall against the end of the extension so it can't come off the output shaft, but not creating any inward pressure at the same time. That's the key to making your extension work without causing any damage that would force you to tear into the transmission of that big engine. Man, I am so looking forward to each video you're doing on this truck. I can't wait to see the test runs, and to hear all those chains.

[@davidowen888]

Chris your skills are always getting better and better, keep on machining and welding on☮️

[@LstrO42]

Slower spindle speed (50rpm) and more cutting lube!!! Mounts looked nice.

[@patiencejoshuagroves7336]

The round stock mount turned out sweet... good idea .

[@thercbarn5001]

Love the engine mounts! And the beautiful machined parts

[@BraxxJuventa]

Thanks for filming Chris. 👍😁

[@jamesdamico7250]

Good choice with the round stock for the engine mounts they do look pretty sick

[@paulblack1811]

The engine mounts look kick ass!

[@johnmccanntruth]

The engine mounts looked great.

[@coleswolemma]

Just a thought… you should take all your metal shavings from the lave an make a video melting them down and pouring it into a knife or something cool, just a thought for video ideas! Great work man!

[@quaileggsvermont]

Yep have you ever taken a good steel ball bearing and spun it in between your fingers??? I have when I was your age! Not thinking of the "What Ifs" Well I spun it with an air gun so fast it blew up in my fingers!!!! Everything went all over! Talk about pain and hurt holy man!!!! I was lucky I did not lose my fingers eyes and them little balls were like shotgun pellets! Yep not thinking!!!! Think of a situation where them chains with only one whip around the sprocket going higher than the speed of sound as it gets momentum around the sprocket! That chain will do a lot of damage at high speeds! Remember it's always fun until someone get hurt! Do your part and protect yourself and others around you man!!

[@michiganmoto7687]

While I think this is a complicated bit of over engineering with all the chains, sprockets and gearing, and I think a shaft drive system would be simpler and lighter, I can’t help but be fascinated by the mad scientist approach and look. This is a really cool build and almost has a steampunk feel to it. ✌️

[@whatsgoingon27]

That’s the nicest engine mount I’ve ever seen.

[@bradley3549]

This is a good lesson in why sometimes using random recycled materials kind of sucks and it's worth spending a couple bucks and buying a known alloy.

[@thecoachrobb]

Man I wish I had your machines. I miss machining as I am a retired tool & die maker.

[@sammylisasmith2104]

Lots of work bud the motor mount is sweet thanks for your time

[@reddenley9822]

Love your channel. Your a awesome fabricator. I watched all your builds. Can't wait for the next video

[@igoro2475]

You are not mad Max, you are crazy Max …

[@vintagetintrader1062]

Would love to see a buggy build using all CV and Uni joints, no chains. If you ever sell it, the amount of chains, sprockets and custom shafts needs replacement, would be a expensive exercise for it new owner.

[@rolandbriscoe4977]

Super awesome build so far, I'm loving those motor mounts and your engineering.

[@shanehaws3828]

Put a bearing on both sides of the sprocket extension to take the chain pulling force off the actual sprocket output shaft

[@danielhelbig1116]

Excellent job man, I love that your builds are flawless such good attention to detail perfect fabrication

[@gamerduck3707]

Hell yeah, new video!!!!

[@bigbaby1177]

Those motor mounts were cool AF!!

[@rdill6371]

You're doing an amazing job! Love the channel.

[@Kirkorr123]

Chris you do great work. Next vehicle should use a Yamaha V max engine with it's shaft drive.

[@michaelcrebbin7328]

Wow you are incredible that engine mount set up is very clever loving watching this build 🥰🥰

[@danf4616]

Maybe that steel has a tendency to "work harden?" I've run into that before. Kind of a pain. Thanks for the videos! 👍👍

[@ThePippin89]

The material was going hard because of the temperature you were putting into it with the drill. You really need to have coolant flow. Or at least some oil on the cutting edge.

[@atsekjoker]

may be i'm a little bit slow, but if you turn the engine backwards and the 2nd gearbox too, you could save some space and chain length. the exhaust could exit backwards freely. no header problems, no heat problems, no chain running forward from engine, so no counter bearing needed

[@scottwright388]

Top notch engine mounts...I know you were proud of those, as you should be.

[@bigboigusytheboys4]

It’s 5 o’clock ish in Australia and I’ve been waiting for this to come up the entire night haha

[@ManiacRacing]

You make some oddball choices in your drivetrains. But it seems to work out well enough in the end. I enjoy your builds.

[@thatoldchevy001]

Kick ass engine mounts. The whole buggy should be engineered connections and thinner linkages IMO.

[@ZrubekFamily]

Dude! you knocked it out of the park with those upper engine mounts!!!

[@acurarl9929]

Don’t be putting lot inward pressure on the input shaft on engine. Seems lil snug no? Engine definitely not made for lateral pressure

[@ALMIGHTYGARAGE]

That thing is badass bro engine mounts are sick never seen anything like it before

[@skylarkeighley2369]

You should invest in a set of carbide bits or use mill bits as they will eat through almost anything

[@jasonbirch1182]

I like the engine mounts. May have to steal that idea sorta on a mini bike I'm building with a little two stroke.

[@hemibreath]

Mounts look awesome 😎

[@MaNNeRz91]

13:03 started talking like Popeye 😂😭😭 glad you kept that in it cracked me up!

[@smokesall]

love the look of the head mount bracket great job this thing is really starting to look like something i still really think you should do doors tho

[@ekengreken]

Love your work. I'm always looking forward to your videos!!👍🙂

[@faulknerfixesall]

hey be sure to design some "droop" in front suspension . i forgot to mention that the other day when i was over there. i am not an expert on small machines like this.but i remember building trucks with my dad and we always were stressing about how much the suspension traveled downward when in the air "droop" it was helpful for average speed over a series of big bumps. the build is really cool good work

[@romienappi6292]

Very cool build so far I would love to do something like this in my garage 😀

[@bobkelly2447]

I noticed you have no retainer for the engine sprocket.... the engine power will eventually force the sprocket out and off the splines unless it is locked on ... I suggest a dowel pin or bolt just beyond the splines.... to hold it on the engine.... a grade 8 shoulder-bolt with a nilock nut should do the trick. she's looking great ! keep at her !

[@rastaralph7154]

It might help if you use oil when your turning on the lathe 👍💚💛❤️

[@Ozarkprepper643]

Your fabricating skills are extremely clean. 🤠🐂🏞️

[@quaileggsvermont]

As fast as I have seen you go, I really hope you really do a good job at covering those chains up! Those what number 40 or bigger chains whipping around would have an unreal force behind them if one broke!!! I hate to see you get cut in half or whatever! It's not worth the big pain and problems healing up cut nerves and after the numbness that follows cut nerves or loss of function or loss! Nothing under 7/16s or better half inch for guards and covers! Thicker stronger is always better!!!!

[@Darkstyx72]

high weight of the vehicle and monstrous power drops for kilometers of chain!!

[@arvidnorberg3530]

Do I need to catch up in another episode or when will a seal for the transmission drive side be installed, seems like a difficult task given the shaft is splined, because that bearing cant run dry you know... Great video!

[@raynyhus2026]

Need to get a oil seal on the transmission output shaft. Great build.

[@mits2113]

Chris the project looks great, and your skills keep improving 😊 One consideration would be the brake rotor, that thing will overheat very fast with a vehicle that heavy. Keep that in mind, maybe a car rotor with more mass would be a better option?

[@airtothewick]

That mount is a freeking masterpiece

[@changethegame113]

Switch your tig cup to a 10 or 12 with little more gas flow. Guarantee you’ll say wow like Owen Wilson. (and a gas saver would be even better)

[@Tristn-1]

I have noticed when you are cutting for the splines you put the wrench on the tool and i was curious why you do that is it so you don't ram the tool into the piece you are cutting and if so wouldn't the wrench cause more damage since its harder steel or is it for a different reason?

[@joshuamorgan2906]

Small stack of washers lol great looking build.

[@petekobraoutdoors7324]

You're an awesome fabricator. 👌

[@silvanotataro8164]

Very interesting project! I love watching it😊

[@wat6816]

those engine mounts are awesome!

[@jasonbirch1182]

I'd like to see at some point a similar setup with a fwd transaxle driven by a bike engine. Then you can run either a chain to the pivot axle like this or run CV axles AND have the option of a LSD differential. You get the gear reduction but if you run an overdrive 5 speed you get that as a bonus too. I've always planned to do that but I've never gotten to it. I'm getting equipped to be able to but not sure when I'll have the time. More likely to build a full size buggy with automotive drivetrain .

[@bigcaputo09]

It's coming out looking sick!!

[@landrelarose745]

Hey Christopher, those are incredible engine mounts.

[@karlalton3170]

Nice job on the engine mounts dude 😁😁🤘🤘

[@matthewmiddleton63]

You could make the secondary transmission move up and down in the slots to tension the two chains

[@johnmorgan1629]

Nice looking engine mount.

[@EJ-74]

That is some beautiful work bro 👍🏻

[@DiHandley]

“Impossible to do an ugly weld”. Just give me a go! 😂

[@tasospotsepis141]

Nice work!

[@Gu1tarZer0]

cutting lube, the old in n out maneuver if it's overheating, and enough pressure to always take a decent chip out- that's what you want lol dude make a new shaper tool holder or weld some kind of spine on it so you don't need to hold that wrench on it

[@anythingmotorised923]

Should be using a cone style bearing as the single row ball bearing isn't designed for side loads

[@kasper.4133]

Yayyyy been waiting all day thanks dude never fail to entertain

[@andystokes8702]

'With this set-up, with this rotary table it's almost impossible to do an ugly weld'. Really, hold my beer.

[@williamnail7672]

Sick work!!!

[@kelbyredmon7089]

I have a suggestion for heating your shop it a diesel heater that you can get at harbor freight just one keeps my 20x40 shop warm with temperatures varying between 80&90 degrees with 80 degrees being the lowest temperature and my shop isn’t insulated that well only has 3/4 inch insulation foam board sheets
