Homemade 300cc TANK / PART 5 ( Transmission ) 

Your rotors are attached with one bolt through mild steel hollow axle tubes - it will work for awhile, but as you brake and lock each track, with inertia the holes in the tubes will get oblong and wear out pretty quickly. Rotori su pričvršćeni jednim vijkom kroz blage čelične cijevi šuplje osovine - djelovat će neko vrijeme, ali dok kočite i zaključavate svaki trag, inercijom će se rupe u cijevima izdužiti i prilično brzo istrošiti.

Уважаю людей, которые "любят трогать дело руками". Ты молодец! Удачи тебе по жизни! Пусть твои дети тоже будут любить ТРУД!

Young man, your vision, skill, patience, and editing are amazing, I salute you. Best wishes from an old man in Ireland.

Bravo. Please ignore all the "youtube engineers" that are saying what you are doing is wrong or what you should have done instead. It's really great to see what you are attempting and I understand you are just making it up as you go, you are young and you are learning. Thank you for the videos, I know in the end this will work and I will be thr first to congratulate you sir.

Интересно,полуоси по сварке лопнут или по отверстию для крепления тормозного диска?

Clutch or torque converter. Needs a 3rd center support bearing at the end of the shaft due to play when you just squeezed the belt. Love your build this far. Please get subtitles for your foreign audience.

No idea what you are talking about but great work. Very inspiring

Пока не поздно, нужно ставить коробку переключения передач. Без сцепления никак, желательно сделать подушки на двигатель, ну или демпфер на пружинах. Удачной сборки! 😉

Yep, no clutch and no reverse. You could replace the primary pulley with a centrifugal clutch, but reverse will require an intermediary gearbox. I would also recommend another bearing near the large pulley at the front end of the driveshaft...

The world needs many many more young men with this talent..

You need a gearbox. It's going to be way too fast. Also a clutch would be a good idea. Makes stopping and starting a whole lot easier. A tip, paint your steel with red oxide when you get it before it rusts. You can still weld it with a thin coat of paint. It will stop weld spatter and keep the rust away and so make final clean up and painting a lot easier. Fantastic work!

Ставлю лайк за то, что в столь юном возрасте руки не из жопы. Парнишка сам варит, сверлит и т.д. Технические решения весьма спорны, сыроваты и слабоваты. Полевые испытания и процесс эксплуатации расставят все по местам. Но за старания еще раз лайк. К 25-30 годам будет грамотный специалист.

A kvacilo, treba ti menjac, jesi siguran da ce taj motor moci da pokrene iz mesta tenk ? Sistem sa diferencijalom je ok , ali treba ti blokada ne mozes ostaviti samo tako. Moraš više da razmišljas pre nego što nešto napraviš, nisi trebao da sečeš bazu tenka, sadsi je dosta oslabio, a i trebaju ti zatezaci gusenica ( jedan pokretan točak koji moze da se pomera i šteluje po potrebi

Where is the clutch? it's always powered this way.

its very interesting to see how you set out the engine and transmission, i would have arranged it differently myself. However i am enjoying this 'series' alot so far and cat wait to see the final product :)

👍👍👍👍This is a killer build. Iv long wanted to have a tank. I'm 50 and back in the day one could buy a M4 Sherman fairly cheap. I remember asking Santa Claus for one lo!. I like the track design. Perhaps to make ease of in field repairs and cheaper bottom !ine. I will use solid steel rods cut to span the entire link and drilled on the ends for cotter pins with washers.So the worry of threads being chewed up and making nut removal a pain . Many Tanks use this drive pin system. I would add this to one or two links on your tracks to ease removal of the entire track or if one is thrown to ease putting it back on. I'm looking forward to seeing it complete. A potato gun would be an awesome final add on one that can fire graffiti 🎉 or tee shirts if you take it to public affairs on holidays. You have made me dust off my tape measure. Thanks for the killer videos I must now watch them all.👍👍👍

The one side of the differential is at an angle. That will cause problems and it wont move easy. Depending on which end is the front, it's going to pull one side or the other.

Thank you for the subtitles. Keep at it: this is really taking shape. I can't wait to see how you solve the steering issue. You'll have to independently control the brakes to do it. Then, you'll need to solve how you stop the treads to clinging to the sides of the rim: that will cause the tracks to fail under load.

That's a lot of hardware for so small of a engine. I love how "just do it" this is, no long term planning at any stage. I really hope it works.

Hi, Really great work but there are a few things I have to mention: Does it have a clutch? The bearing on the transmission shaft is way to far from the pulley. If you put tension on the belts the axle will flex and you put a lot of additional stress on the bearing. Second thing to the transmission shaft: why you didnt put some spacers under the bearings? now the shaft is under permanent stress and the bearings too. As mentioned by others the missing bearing on the rear axle or wheels caused them to dont line up anymore with the tracks which will make them stuck or lead the differential to deliver constantly more power to one side so you will always drive in a circle and not straight ahead. Im really interested in how it will drive and are hoping for the next video. Regards

Hey caution cover that drive shaft with a protective metal or hard plastic cover to avoid getting clothing caught in it when its spinning!!! That could pull and arm or leg off!

You definitely should install a clutch system like on snow mobiles

Say what you want, This guy is good at what he does. Bravo!

You’re going to need to put a clutch or torque converter on there so that the drive sprockets don’t spin whenever the engine is running. Might also want to consider some lower gearing depending on the weight of the finished tank.

You are going to need a bearing block right behind the large pulley (too much flex in the shaft) and it is geared WAY too high. One way to reduce the ratio would be to make the the track drive "sprockets" out of smaller diameter rims. You will need more of a gear reduction than that, though. Other than that, it looks so cool! You'll figure it out. Thanks for sharing! :-)

So awesome to see it all coming together. I am sure that is a great feeling to see the engine running and drive sprockets turning.

God bless you young man! Can't wait to see it finished!

Looks nice! I’ll be watching the rest of your videos shortly.

Sweet, only the gearing is way to high for the weight, its gunna smoke belts if it even moves. Adapt a gearbox and run it chain drive with a clutch of some sort, only way its going to be reliable. Then you will have reverse also. Tinkering and learning new stuff always a good time though!

Another fine job, can't wait to see it in action.

Theres nothing like having a "good Turner" around when you need one! Awesome!

Блин я конечно хотел бы похвалить пацана за его труд... Да вообще то он молодец, старается. Но ему хоть бы помог что ли кто-нибудь! Он же нахрен таким макаром в российский автопром попадёт!

Clutch?

Phantastische Arbeit, junger Mann !!! Mein Respekt !

Awesome tank project, building things is fun. Thanks for the video

I don’t want to be a back seat builder but you should heat up those tracks and synch them in used motor oil to slow corrosion

you need a extra bearing as close as possible to the pulleys now to axle has way to much bend in it when you activate the belt tensioner

Bravo young man, if you have a problem with a part, just fix it. Live and learn, no problem.

Parabéns pelo belo trabalho, aguardando a PARTE 4.

You have excellent fabrication skills 👍

U need the clutch and the maybe a reverse gear

The prototype tank is amazing... I was inspired to try to make it. Greetings from Indonesia.

I love it! Keep up the good work! I subscribed😊

9 лошадок маловато для гусянки. Надо было делать на электро приводе и батареях :) был бы в тренде.

Cool build man. Just an idea maybe try a VW beetle transaxle with a 1600 motor and get more power and reverse to, pulse more control with a clutch.

Nice metal work! Great engineering!

Yehey Finally with English translation, thank you so much , more power to your channel

Amazing project! Good luck guy. Greetings from Brazil!

Dude you are impressive

I am looking forward to seeing the next installment. Looking pretty awesome!

Totally awesome, and very creative. 👍👍👍👍

No clutch to stop power to the driveshaft when sitting still?

I would love to hear your narration. Is there a way you could include subtitles?

For brake steering the best setup would be one where a very low ratio (1:1 being ideal) differential with brakes was used before the actual final reduction gears. This would reduce the strain on the brake discs. Most commercial traction steering system use multi-differential systems but those are tricky to replicate in a compact and reliable way by hobbyist on a budget.

Great bit of construction love the vids but how are you going to engage and disengage the drive ?? Start i9t up and it will either stall or drive off on its own. :) Keep em coming.

Fin projekat. Moje mislje je da si trebao ubaciti citav mjenjac umjesto tog difrencijala. Imao bi i rikverc i daleko sporije brzine. Dugacka je to brzina (tesko ce i krenuti) za gusjenice a i za motor od 10-ak ks. Ne vidim kvacilo, ali izgleda da ces ga rijesiti španovanjem remena.

Pozdrav iz Slovenije! In english now, make sure to make some sort of "case" or protection box for all the rotating parts BEFORE you attempt to drive it. That yellow thing that is spinning there is lethal (you know about tractor accdidents when people get caught in....kardan....) Great videos, keep it up! :)

Doctor D.S. надеюсь сможешь перевести... - после ремённой передачи (можно использовать как сцепление) тебе нужно поставить последовательно 2 КПП для понижения оборотов и увеличения крутящего момента

I can tell you all that this drive set-up will not cut it...It needs a pair of hydraulic motors...one for left and one for right...That will give you forward and reverse on each motor independently...eliminate the brake discs...They will not have enough grab to turn that heavy of a vehicle...No way to run one track in reverse...The engine will need a hydraulic pump attached to run the 2 hydraulic motors...I've been following this build for a while now but Doctor DS dropped the ball on this video...

Great! I hope we can see the finished product.

Now just the extras . You are awesome kiddo!!

Сойдет проехаться 50 - 100 километров. Потом или дифф рассыплется от переменных нагрузок даже без биения, либо гусеницы сотрутся оттого, что задние колеса под углом к остальным расположены. Ну или гусеницы будут слетать и заклинивать. Биение полуосей разобьет дифф и подшипниковые узлы еще быстрее. Один подшипниковый узел на полуось с радиальным подшипником с переходом на шрус вообще детское решение, как раз по возрасту автора - рассыплется под нагрузкой почти сразу. В целом конструкция работает, если дифф от грузовика, и два шруса на полуось, а не один, + другое крепление полуосей (без радиальных подшипников, которые вообще-то работают парами). Сцепление будет, кстати, как на мотоблоках прижимным роликом. Самое простое и оптимальное для легкой конструкции. На сайтах вездеходостроителей все эти косяки расписаны в деталях, с фото наступивших последствий.

English subtitles please :)

Excellent skills and imagination. I don't know anyone building themselves a personal tank.

Awsome job looking forward for the next vid

Detecting a slight problem.... You need a clutch and a reverse gear

It seems that a clutch or transmission would be needed instead of direct drive. Those belts might take a beating with the drive pulley spinning with the vehicle standing still. And, is that motor going to be big enough to move that beast?

I noticed when u put tension on the belt by your hand the shaft tends to bend a lil bit. I thin you need to reposition the pillow block little bit nearer to the main drive pully.

Dis is so cool! Imagin a homemade heavy tank...

Man, I am from Croatia, and I rarely subscribe to a Croatian channel. Keep up the good work. ;)

I suggest you to install something overhead outside to make you safe from rain. ❤❤❤❤❤

Ты как волшебник) Молодец!

14:55 Dude that 'vise grip' thing is awesome.

fala bogu da ima neko sa balkana da snima ovako nesto.ekstra video!!!!

Decko trebace ti menjac,tako nece imati snage ni da krene,mnogo vremena i rada ulozeno u sve to pa ti na tome cestitam

Parabéns pelo sua dedicação e também poder compartilhar. Seu fã aqui do Brasil.

Congratulations my friend, you are doing a great job, well done again. Greetings from GREECE .

Looks like he main concern in the comments this time is that the engine doesn't have enough power. I eagerly await to see how you'll prove us wrong in the next video!

If he lived in America, it would definitely be Texas.

Have no clue what your saying or what half the comments are..lol but keep up the work and don’t let them stop you. That said there are definitely some design flaws here but only way to learn is trial and error and it’s nice to see younger people actually still building stuff. 👍

Молодец. Не рукожоп парень. Ждем продолжения.

Good doctor d.s👍

Kid builds his own tank. Still a better weld job than Tesla :)

hey buddy great job a few things from the video the tracks are to tight and you should fabricate a tensioner pulley to adjust track slack the other thing is there has to be play between the drive sprocket and the tracks here's why tracks twist and turn and need to have room to grab the track again without binding were they grab the track thanks

Great video man. Good work so far.

Hello, good tank my friend, Brazilian here.

Obrigado pelo vídeo prof. Como sempre excelente explicação . Gosto muito da sua aula Muito bem explicada . Pai eterno,abençoe sempre,bastante prosperidade na sua vida amém.

You need to have a idler wheel to adjust track tension. You don't need that many return rollers at the top 2 on each side should be fine the rest are added weight

Looks fantastic brother

I have a number of major engineering concerns with this project. Unless they are addressed (and you may have plans for this) you will quickly run into trouble. 1. The driven axles have one bearing only and as the driveshafts have been welded on, no means to add another. This will break very quickly. 2. The prop shaft pulley is only supported on one side and again the side loads involved will cause strain and wear. It needs support on both sides of the pulley 3. There is now no way to remove the drive shafts to the wheels for maintenance, repair or modification. How do you change the brake discs? 4. There does not seem to be a clutch mechanism, if you are planning on using belt tension as a clutch, then this makes point 2 doubly important. Sorry to sound so negative, but this is a good project that was going so well, and suddenly compromises to get it finished have the potential to ruin a lot of good work. Have a think and hope you come up with solutions.

Nice nice.. but slow it down a bit. I know you're excited to get it going and all that but take some time and think. A lot of places aren't in line, the welds aren't really that good (welding takes patience, move the nozzle slower) and as other people mentioned it's missing some major parts. You need to modify it before it goes as it's supposed to. But you'll figure it out. Keep going!

Woww brother!! Felicidades lo estas logrando

i woulda left pillow block bearings in to keep stress off of cv joints.they be flexin n poppin.shoulda just undon axle stubs n fitted cause you already had everything lined up.now when you re track again tension be all on cv joints. just my thoughts

Hvala brate

It would be nice if you had subtitles as not all of us speak your language.

Very impressive the English have a name for people like you edsentric :) all our best inventions was made buy a bloke in his shed 👍 love these tank build videos keep up good work 🇬🇧

Good work bro! Waiting for next parts!
