Had to leave my comment. Loved the idea, was looking all over RUclips, found a Brazilian that had a similar ideia but yours is much better concept. Will put this information to good use :)
MCanha awesome! Glad I can provide some help. This was many years ago and there is lots of newer designed parts that work much better. The dozer still works just as good as they say I built it. Good luck!
Your use of what looks like a bicycle chain is a good idea, and what you have so far is well made. I would suggest adding a spring tensioner on the dozer tracks - an idler with spring loading would work fine. I have a Struck Magnatrac (mini dozer) and the front sprocket has an adjustable spring tensioner on it. Some use bogey wheels with spring tension (also can add a bit of resiliance to the dozer and make for a smoother ride). The right-angle grousers (name for the 'shoes' on the track chain) are interesting (my mini dozer has add-on channel grousers and they REALLY add to traction, but can tear up the lawn). I've seen grousers that were angled so that when flat, they overlap each other slightly. That helps to keep crud and so on out of the gears and chain. I'm curious as to how it all turned out.
I had to make the little "L" brackets and it came in 4 foot lengths. It attached to the chain and to the track pad. I have had rocks get in between the tracks but has no problem breaking them. So its not a issue at all.
@Tepsija20 Thanks, The motors them self have quite a bit of tourqe...I wanted just a bit more so thats the reason behind it. The model is 100lbs, so most of the power from the motors when into moving it. When it came time to push somthing the combination of the weight of the dozer and the pushing of the load was quite a bit for it. After I did the mod, it showed a big improvment. I would recomendgetting the most out of your motors by adding gears! Good lucK, and post vids.
I did... Its made out of 1 inch square tubing... then cut the 1/8 inch flat bar into the shape for the road wheels, welded one side, then bolted the wheels to another identical piece.
I bought 1 1/4 inch flat bar from Lows, cut it up into 2 inch peices, bent 1/4 inches up to give it that "L" shape. Drilled holes and attached it to the little "L" shape peices then to the track (chain).
@Warrioryz125 check out the Sabertooth motor controls. I used the 25x2 for the DC drive motors (car window motors or wiper motors either or) for each track and used the 2x5 for the linier acuators for the blade control. They each rin from the radio receiver. Check out my video on the set up, under dozer rebuild.
@1goldenclaw You will have to search: Blade actuators from E-Motion LLC, Robot Market Place for motors, McMaster-Carr for chain, sprockets, and belt pulleys (wheels) and Dimension Engineering LLC for electronics drive and blade motor control. All steel and hardware was purchased at home depot/ lows. Radio and receiver at local hobby store. Its all DC 12 V power, currently use a rechargeable Power wheels battery from Wal-mart. Be sure to check out my rebuild videos!
@colvin56 I got them from McMaster Carr (website) for my application I used Nylon Flat-Belt Idler Pulley 3/8" Bore, 1" Belt Width, 3" OD Part Number: 6235K63 They were around $11.00 each, I also got the drive sprocket from them as well, Part Number: 6280K911 . Just have to make sure the bore hole fits your drive motor or your drive shaft.
@mr7sounder I have little under $1000. Big cost items, DC window motors $50 x2, 8ft hollow pin chain $100, Liner Actuators $90 x 2, Radio and Servos $150, steel, nuts and bolts..around $100, 4x wheels $50, sprockets 2x $25. Bought the steel, nuts/bolts at Lows/Home Depot, ordered chain, sprockets, wheels from Mc Master Carr. Motors from robot market place, liner actuators from E motion LLC. Bought radio w/ servos from a hobby store.
@DeerSlayer612 I didnt use any instructions, Its one of the biggest questions I get asked, but what I did is study other models on You Tube and picked up a toy one to have a 3D model. A lot of what I did was trial and error and built it out of my head. Have some rebuild videos as well and they show more on the wiring and the inside structure. As far as the weight its around 94lbs. Quite heavy for something relatively small.
what about the pad connection to chain? you were using some side plates? do you get rocks and debris sruck between the pads? they get quite spaced aapart running over idler wheels?
The track that I built has some weight to them! prob about 10lbs each.....Im sure if you scale it down with a smaller chain and thinner pads you would be ok. The chain is number 40 and the pads are 1/8 thick....and is 4ft in length.
I dont, I used a heavy duty vise and a hammer... for the next build I will have a bender...also a drill press, plasma cutter, and what ever else I would need. The model in the video was built all by hand tools.
@Tepsija20 I ordered the wrong size, the smaller one is now on the motor and atached to the gear chains on the inside. If you look at a real dozer the drive hub and the road wheels are just about the same size, I wanted to keep the same ratio. (all 3 inch)
Ben Higgins just noticed your comment, but I used 1 and 1/4 inch flat bar that is 1/8 inch thick. if course I cut a small cut at the 1/4 mark and bent up the "grouser" part. 1/8 inch would be good too! I cut 2 inch pieces of the bar, that was 8 foot long. Hope this helps!
@loyalton1200.... I don’t think I would build one for anyone. I would be happy to offer some advice to build one. I was once in your shoes and wanted one so bad but couldn’t afford to pay thousands of dollars for one. So I built my own. A lot of learning and trial and error and with that money. There would be a lot of things I would do different if I build a new one.
adib hosaini for the chain I have the L shaped pieces are 1 inch long by 1/2 inch wide. It's that size because of the length and height of the link. Hope this helps.
***** The sprockets have lock screws that keep them on the axel. Problem I had was that the motor axel was a tad bit smaller than the sprocket hole. I had to cut a thin shim from sheet metal to fill in the gap. I also tack welded to insure it was locked on good. Hope this explains it.
@toybulldozer902 I can help you out with that....where do you want to start. I can give you the web pages where i bought parts from and how to get it together. The one I built took me about 3 months to get it together.
Now then mate (metelbod) its joe, i have forgotten your name sorry haha...i have uploaded some videos of my dozer nearing completion feel free to have a look if you want to they are on my channel..sorry for the bad camera work haha..you might want to skip the boring bits...
TWOLF365 the motors I use were from Robot MarketPlace and they are the left and right, AME 218-series 24V 212 in-lb LH gearmotor - I first went to a auto store and bought the cheapest wiper motors but I didn't like them...didn't have the right mounts and they were mostly plastic mounts. I would just go ask a store clerk and look at what they have in stock or visit a store web page.
erick vasquez caicedo Hola, compré la cadena de pines huecos # 40 por alrededor de $ 160 / $ 80 por cada lado de una página web llamada Mcmaster carr. ¡Espero que esto ayude!
Scratch Built RC Dozer and Ship hola gracias por responder....quisiera preguntarle algo más ..la instalación del sistema de radio control es díficil?..yo estoy tratando de construir una excavadora de madera...para enseñarles a mis alumnos ..tengo un avance del 30% aproximadamente pero me falta varias partes ..cómo por ejemplo los motores reductores y el sistema hidráulico para la motricidad ...pero en Perú muchas de las partes mencionados o no hay o son muy costosos ..entonces agradecería tu ayuda con nuevas ideas sobre cómo construir algo de manera económica...gracias saludos desde Perú
erick vasquez caicedo the radio comes paired with a receiver. that receiver then would control a motor controller that would control the linear actuators. a battery would be conected to the motor controler and be supplying power to the actuators. this would beused in a larger system. there is smaller liner actuators. there are smaller actuators that would plug directly into the radio receiver. check out mini RC actuators at robotshop com
erick vasquez caicedo la radio viene emparejada con un receptor. ese receptor controlaría un controlador de motor que controlaría los actuadores lineales. una batería estaría conectada al controlador del motor y estaría suministrando energía a los actuadores. esto se usaría en un sistema más grande. hay actuadores de revestimiento más pequeños. hay actuadores más pequeños que se enchufan directamente en el receptor de radio. echa un vistazo a los mini actuadores RC en robotshop com
I finally started to work on my tracks for my rc machine. Check out my channel. Thanks for your videos it was alot of help and now I will upload videos to help others.

WELL DONE..!! thanks for posting
Best home Made..
Really simpel..!
I like this..!
Tomorrow, i try make it
It’s simple. Some took it further than I did and made some really nice models.

very cool your track good idea
Very good
I would be interested in seeing what ya come up with! Be sure to post a video or two if ya can.....good luck man!
Ok thanks! I really like you videos.

Oh wow very creative I must say. I was going to use crawler 70 Turns and also where did you get those hydralics for the blade?
Thanks! It works, but could be better!
they are 12V car window motors or wiper motors either or. I found them at (Search) Robotmarketplace. They have bigger or smaller motors as well.
@1goldenclaw Its all sheet metal I bought from Lows Hardware store. its thin and easy to bend.
what about the pad connection to chain? you were using some side plates? do you get rocks and debris sruck between the pads? they get quite spaced aapart running over idler wheels?
nice video, thank you! Where did you get those metal pieces for the track? or did you make them yourself?
@DeerSlayer612 Thanks, I have more videos in the que for up-load. Enjoy!
awesome! Do you have bending machine at home?

wow long name and thanks and what gear set up did you use on your dozer
I dont, I used a heavy duty vise and a hammer... for the next build I will have a bender...also a drill press, plasma cutter, and what ever else I would need. The model in the video was built all by hand tools.

@CBR1100xx31 Glad to help.
hahaha just got back from making a few....had to make that repair on the undercarriage first
also did you make that metal frame by yourself?
@1goldenclaw also see some of the other comments below, if you need more info let me know, Im happy to help and share what went well and wrong.
Im building a RC tank with a câmera to use like a drone in airsoft games. You gave me good ideas. Thank you!
Yuri - São Paulo, brasil
where can they be acquired?
how do you make the actuators control the blade?
What website did you get the instructions to build this from? And how much does this weigh?
What kinda motors are those exactly?
search Robot Market Place for the website then motors then you will find all kinds of motor styles.
what kind of metal did you use for the track pads and angle bits? thickness would help too :) getting close to figuring things out.
Ben Higgins just noticed your comment, but I used 1 and 1/4 inch flat bar that is 1/8 inch thick. if course I cut a small cut at the 1/4 mark and bent up the "grouser" part. 1/8 inch would be good too! I cut 2 inch pieces of the bar, that was 8 foot long. Hope this helps!
Ben Higgins Q
Hi, I wanted to know which chain you're in the bulldozer.
matias perez hello, it's #40 hollow pin roller chain.
@loyalton1200.... I don’t think I would build one for anyone. I would be happy to offer some advice to build one. I was once in your shoes and wanted one so bad but couldn’t afford to pay thousands of dollars for one. So I built my own. A lot of learning and trial and error and with that money. There would be a lot of things I would do different if I build a new one.
@toybulldozer902 where can i buy the front and rear wheels
verry cool
When will you be making more videos
Wish I could, cost about $1000 to build, I just don't have the time.
Hi can you please let me know the dimension of the small (L) shape which connected to both side the chain
adib hosaini for the chain I have the L shaped pieces are 1 inch long by 1/2 inch wide. It's that size because of the length and height of the link. Hope this helps.
thanks
The chain you are using have no pin. What type of chain is it.
Ray Wolf it’s a number 40 hollow pin. Check out my playlist on how to build a dozer and I have a dedicated video for the tracks.
how much would it cost for you to build me one that is a serious question too lol
How did you fixed chains pocket with wiper motor axel?
***** The sprockets have lock screws that keep them on the axel. Problem I had was that the motor axel was a tad bit smaller than the sprocket hole. I had to cut a thin shim from sheet metal to fill in the gap. I also tack welded to insure it was locked on good. Hope this explains it.
@toybulldozer902 I can help you out with that....where do you want to start. I can give you the web pages where i bought parts from and how to get it together. The one I built took me about 3 months to get it together.
Where did you get your drive sprockets?
got them at website; McMaster-Carr
Ice
Hi
where did you get the wheels from
I got them from a website called McMaster-Carr. They are a belt pulley wheel 3 inches in diameter and 1.2 groove.
Now then mate (metelbod) its joe, i have forgotten your name sorry haha...i have uploaded some videos of my dozer nearing completion feel free to have a look if you want to they are on my channel..sorry for the bad camera work haha..you might want to skip the boring bits...
Are you selling this! Will buy it!
MasterMind naw, maybe one day
@@scratchbuiltdozer Will pay you good bucks. PM me.
can u build 1 4 me?
how much?
thx
yrehuda
I see you used a windshield wiper motor. Is there a certain type I should use?
