Who's here after Colin furze videos ?
The TH-cam algorithm reunited us
This video is getting a lot of extra views because of Colin..
@@896gerard it's good for this channel, check out his videos he's doing great stuff ❤️
Will be an interesting comparison. Cause furze is building his ground up. Where as this is a ride on lawnmower conversion.
I searched for this
Me, 2 days later.
Who else is here after Colin Furze ?
*_"Behold, the Underminer!"_*
Hahaha “basically I’m screwed” 👌
I really admire this guys patience. No one should knock this in any way.
Bravo! Well done! It is great to see some of these concepts return after so many years. Some of the "old" ideas had quite large screw mechanisms that purportedly provided lift in wet terrain. Thanks for the your efforts and the video and best of luck!
Chrysler Corp. experimented with a screw drive back in the 1960's.
I remember it probably had an automotive type engine and the screws turned very fast.
It had a much .ower center ter of gravity.
...... but great job, you're a man of my heart.
Keep trying .
Your a hell of a mechanic, I'm impressed ! I like the other one, it seems to work fine. I'd like to have one my self.
7:34 "So, basically I'm screwed"

umar
You have earned a thumbs up my friend . When I heard those chain skipping sounds I feared the worst. You have had the opportunity to drive something very few people ever will drive. Too bad it didn't hold up longer for you. I guess you'll get that lawn decoration after all. Remember , life is more interesting if you get off the couch and try something. Congrats for that. I can't wait to see what your next project will be. Thanks for the show. Joe

"A smooth sea never made a skilled sailor" much respect on the design dude keep it up perfect the design then market it.
Don't be down hearted man you and few others know the joy and gratification of thinking building and using what comes from inside. You are truly inspiring
Thanks man! Glad you liked it....its a work in progress, hehe. Im on part 12 now! Geeze....
As they say, "Rome wasn't built in a day".... keep at it Rednic, you'll get it. You are MILES ahead of anyone professing negativity in their comments. I see a splendid mechanical mind at work. Take a look at this link and you'll see what you are trying to accomplish is within reach. FordSon Snow Machine
Keep up the good work.

2020: OK IM ADDING THIS TO YOUR RECOMMENDED!
I think it's commendable that you're exploring a screw drive machine. Without something else to compare to, it's difficult to determine weak points in the drive train. Like you said, those screws create a massive amount of torque or resistance for the rest of your parts. Good job and good luck if you choose to build another one.
that is great work. I have always wondered how the screw drive vehicle runs on mud. Thanks for sharing this.
I have an idea, turn it into a tractor! they tend to work pretty good.......................
Da Man l'm dead you bitch 😂😂😂😂😂
I feel like any kids who COULD try this at home should be prized and encouraged
This is an awesome project... looking forward to check out more of your inventions!!
Show me a man that has not made a lot of mistakes
and
I'll show you a man that has not done much of anything.
Hats off for effort and heart!
Great vid.
"Extreme Off Road" - Nah, just some dude with a weird ass home made backhoe trying to tow some weird ass home made tractor sideways.
That was actually really badass for a test run on a prototype. If you give up on this, others will figure it out.
The Russians had military vehicles like this decades ago I watched one of the videos the other day they went across land and lakes with it.
heman691 yes I saw the video on YT
But it wasn’t reliable, it would break if it hit rock etc
Still produced and used "ЗВМ-2901"
Such a cool project! I admire the effort.
+PiperCub49 thanks!

Decent !!

might have failed.. but I damn sure can respect the work done. trial and error my friend, im battling a mower boat currently lol
+Zach Hoyt thanks! mower boat? sounds interesting
Mower stripped down put on aluminum frame + aluminum jon boat. I was trying make it a 4x4 but wasnt successful so settling for 2w.
+Zach Hoyt right on! so it would be amphibious?

Pond with too many reeds in it?
No lots of gators lol
yes this is amazing!
love the creativity, also the Canada flag on the hood while dragging it out :)
When you said “ it’s screwed” I literally thought it was a joke lol
Hey bro hope u never stop inventing things..keep it up man you should neve give up on ur dreams of becoming great..God bless
+stroull thanks for the support!

Some folks build some weird shit! I laughed so much, I almost pissed myself!
They use them on the Model T.
1929.
Awe that's a bummer. What a cool project. I suppose something like that has to be wickedly over built due to the varying conditions it would have to overcome. Come get some Catspit~!
Н
This is the first screw drive i've seen. I like the way you think! All good wishes.
Oh my gosh, when my wife told me she wanted a "screw machine" I assumed she meant some sorta perverted sex toy. Imagine my relief when I came across this video. Thanks!
Better with her having a screw machine?
Your wife isn't nearly as cool now.
Depends what she wants to do with it
The only thing that needs to happen is that he needs to lessen the torque on the chains. Smaller sprockets on the drive side and larger sprockets on the ends of the screw ends. Either that or some kind of planetary reductions in the middle. My father has built many different things. One in particular was a wood splitter that just pinned right on a backhoe. He had to revise it 19 times before he got it right. We used it for years. We split 1000s of ton of wood with it. It would split things that 10 men couldn't handle. it was amazing. But, the first time he ran it, I think it broke splitting a dry pine 2x4. I tell you this to keep you going. Keep working on it. Two critiques: I think your screws need to be larger and your final drive needs to have at least double the ratio to relieve the pull and twist on the tractors output. Good luck!
+George Bowles thanks for the input! check out my newest video, i would be interested to see what you think of the size of my new screws. thanks!
+REDNIC79 you my friend are a beast
+George Bowles 100 bucks says this guy don't own a toolbox!! armchair pencil pusher LOL "my father has built many different things" pshhhhhhh
+K0AXE Think what you want, but, you do realize that I made a typo. The "torque on the chains" was incorrect. Should have been tension on the chains. Armchair pencil pusher? Hehehe. I laugh. But, you are correct. I don't own "a" tool box. I own a full set of tools plus a pretty extensive one for both the car and the truck. So, egg on your face, however, I won't hold it against you because my typo made my paragraph sound stupid. Also, when I said "My Father" that actually "My Father and I" since I often had a fair amount of input. Regardless, how was your comment helpful? I was at least attempting to help, though, it looks like this guy's mechanical abilities don't need much support from me. Please, try to be nice instead of criticizing people.
+George Bowles Ehh why feed the Troll's? Keep up the creativity & fun, Thanks for sharing with us! :D
i really love the invention of yours
you are a real engineer YOU TAKE, BREAK and MAKE things
just loved the screw drive vehicle and i became fan when i saw your EXCAVATOR
my God 2 wheel 2 supporting arms and 1 excavator
just fantastic
loved it
hastala vista you made it
A mechanical drivetrain like that is going to have all sorts of forces lateral to the torque. My first inclination would have been to have a hydraulic motor directly mounted on each screw. That would make torque the only stress on your frame, and eliminate the chance of bending any axles. Heck, you could put one on each end of both screws with "armor cones" over the front two, and voila - double the torque!
+Darth Annoyance yeah you are very right!
+Darth Annoyance I was thinking: "I would have used hydraulic motors directly, instead. See if anyone else said it.."; First comment!
What did scare the shit out of me though, was what might happen if you fell off, or something got caught in those screws (or the open drive chains).
you truly are a mad scientist
+justin taylor hehe, thanks!
Trevor Lahey
7:23 think I see a verry entusiastic and amused girlfriend in the background, they allways love these kind of verry important projects lol.
Wow man you built that. Thats amazing excellent job. Sorry about the transmission busting i hope you get it going again real soon. Maybe you can strengthen the areas that gave trouble. Way to go on using your skills and engineering mind Gos bless you
That’s nice project!
I have a ideia for you
“Two different section, the chain transmission, in a middle of this will prevent failure
it looks like your a clever mechanic and love to build contraption that serve absolutely no purpose whatsoever
screws need to be a lot bigger !
+decoysk Will this fit on my Honda?
+decoysk
Yes, they actually need to have enough buoyancy to float the vehicle.
+kenya catholic Yes exactly, that's what I was thinking. They need to be like pontoons that way you have the buoyancy and stability needed to carry a much heavier drive.
+decoysk Right a tent stake would stop it now.
I would move the drive chain that turns the screws, to the middle of the tank. Half way exactly. Now the torque is distributed evenly front to back. It would make life on that rear bearing a little easier....lol. Good luck, friend. Keep at it.
Nice attempt! I agree with dreamTheory go with hydraulic motors mounted on the back of each cylinder - that gets rid of all the structure and the chains and their tendency to bind with mud. You can then use the hydraulic valves in place of the brakes and simplify the drive.
great engineering, looks very cool. Im seeing a lack of efficiency though. thats my only gripe. beats walking with weight though.
most inefficient machine i have ever made :)

Interesting build the one thing that I think was the down fall was the course thread on the screws. If you were about half that it would have likely worked better. The most of the load is coming from trying to push the ground sideways not moving the thing forward.
Kriss Femmpaws yeah your are right in some ways for sure....although i still needed a way for the transmission to 'slip' in high load situations, such as a jammed screw. thanks for the input!
REDNIC79 Use a shear bolt like they use on a lot of farm equipment it's easier to replace than a jam screw. Go look at an old hay rake or bailer,
Kriss Femmpaws you are the first person to mention that idea. It so simple i cant believe it had not crossed my mind, hah, if i would have done that, im sure i could have saved it! Some times its so hard to not over think things, i get caught up in my own mind. Thanks, thats great stuff, so simple, so smart.
REDNIC79 one advantage I have is 45 years working on or building stuff so I have a good background. I would say make your pods about 4 feet longer and the helix pitch about half of what it was. By making it longer you will have room to put in failsafe in the system. I would look using belts for steering clutches and that would be your safety.
REDNIC79 stvarno :) hahahahahaaaaaaaa
very first person....hahahahaaaaaaaaaaaaaa
it is serbian idea 1950's russian army very used this serbian idea.
Dude, you are an awesome inventor!!! Nice work! You'll get it to work better next time!
+Mr G thanks! Check out my channel rednic79, im still workin on it!
He didn't invent it ... It was invented in 1907..
Wow, what a work of art! Looks like it just needs a little fine tuning.
I think the larger diameter pods will help. it should spread the weight and you won't sink in as deeply into things which is where the large amount of torque was used. with more surface area the vehicle should float across services more easily. one other thing I thought of rather than using chains and sprockets on the end of the pods, what about using a hydraulic drive unit at the end of it. it would be mechanically more simple you could have an engine with a hydraulic pump and then the hydraulic drive units. keep working on it it's an interesting design and certainly has advantages over wheeled and track vehicles. these things were used in Russia and other places get over terrain with no other vehicle could get to. good work on the mechanicals by the way. Always fun to see someone build something and try to make it work.
But bigger screws requires more torque, so that's harder on the trans.
Steven King But powering it by hydraulics would remove the transmission from the picture
Steven King
Sure would. Maybe do some gear reduction after the transmission... To reduce the stress on the trans itself.
Interesting and cool project for sure.
kens97sto171 That's a damn good Idea!!!
kens97sto171 Good Day kens97sto171 . This drive mechanism is is what I thought up about 20 yrs ago , it'sa very intriguing ; helicoidal drive , screw drew drive , spiral drive . Just like a mechanical "helicoil" I, m an aircraft technician since 1980 , I went through college for tool & die design and started out out in Military Turbine engine . Toronto , Ontario , Canada . When you're explaining an idea to engineers or tool & die makers it always works to make use of an example . Could you please extrapolate with this example of hydraulic drive in this application ? . Do you mean a torque converter drive ?
love the bison ornament
thats a big moose eh?
Awesome build. I can only imagine the amount of torque that drivetrain has to withstand.
Great idea! I think you need bigger cylinders to increase the impact area with the mud.
MADE WITH GEAR HYDRAULIC MOTORS DISTRIBUTOR ONE PUMP AND PIPE FITTING......IS THE BEST
+luciano gianfiori That's what I was going to suggest as well.
Don't give up. You're very clever.
thanks! i havn't given up, check out my channel, rednic79

Dude, You are fuckin brilliant! I found your stuff by a strange journey on youtube. So enlightening to see this! Theres nothing better than ingenuity at work. Much respect to you. I'll look forward to seeing more of your vids. Best of luck!
+tom pelley thanks for the support! cheers!
REDNIK79, buen invento nomas lo que te le falta es proteccion enfrente y atras en las barrenas, y atras en las cadenas, y engranes para protejerlas del lodo, felicidades, desde texas.
looks good... I just think you need a stronger engine though...

Dan Grecu what
Red Green would have fixed it with Duct Tape.
RoadCaptainEntertain He shoulda said a little man prayer before starting
If the women don't find you handsome, they should at least find you handy.
Wow it seemed to like the thick mud before the incline better than the hard ground. Really neat idea
Trial and error. That's why it's called experimentation. You'll get it to run eventually. Good Effort! Keep going!
bravo
+PANOS SIOPIS thanks!
Screw off
Get it
Does it go any slower!? 😁
moulin6801 yes
when its turned off
that is so cool. hope you get it back working. would like to see another bid on it
one of the coolest builds on youtube
I would be digging a a random hole if I had a tiny excavator too
+Todd Verdin yep, its quite fun
7:35 "basically I'm screwed" HA I get it. Cause it's screw powered. 😆😆
YOU DIDN'T FAIL! What you need is the technical support of an interested auto-manufacturer who can stregnthen your work with a much more sturdy drive train. Don't give up!
A great idea, go back to the drawing board and get that final drive fixed. That little thing is awesome!!!
+JR Conner i'm workin on it. almost got the new screws done, check it out on my channel, th-cam.com/users/REDNIC79
thanks for watching!
why not use a hydraulic pump and two drive motors less moving parts no drive shafts or chains to worry about
my thoughts exactly
Good idea, but cost is what made him do it with what he had available. If you don't fully understand how hydraulics work, you can really waste a lot of money really fast. Keep it simple unless you're made of money.
@@scottmackenzie6796 Hydraulic is actually quite cheap!
this is probably costly, but make it hydrostatic with hydrolic motors hydrolic pump
joe muncey its not costly, the builders over here like Howe and Howe tech just use ZTR mowers to source all the parts.
Diesel Ramcharger kg. Gvhgh fb
and q12eeetr
william mayor Yup, you're an idiot. I totally agree!
Well I'm guessing my kids have been playing with my phone again. Thanks mate
william mayor lol well that makes total sense then!
That's awesome. I hope you kept with it. Those exposed chains and sprockets are an open invitation for stones and such to jam up the works though. Ideally a hydraulic solution or a sealed induction motor or maybe a repurposed power takeoff for each screw would be better. Maybe throw something in there to slip before stuff breaks then apply power on both ends of each pontoon with a taller screw thread so less contact area on harder surfaces makes it less likely to get locked.
I don't think you'll ever be able to tackle an approach or departure angle that acute outside of deep sand or snow though. At least not unless you use four shorter pontoons that can move a bit independently of the frame and each other, maybe throw a shock and spring on each corner as well as a flexable Ujoint where the middle of each pontoon is now with a shock linking it to the frame. Otherwise you'll have to stick to relatively even ground with smooth grade transitions.
Must be a pain to try and tow that thing on ground when it's broke down. Maybe include a couple skis/slats you can jack down to make recovery a little easier.
That was great! You know what I would like to see is -- put bigger screw shafts on with larger blades. Like on a house boat. This will work on water. Lot less resistance.
why not goto hydrolic drive motors ,dirrect drive or geared @ the pods.
That back hoe is awesome. Sounds like a wood splitter I used back home in the Chilcotin. As others have said. Don't give up. Go Hydraulic drive ....
Wasn't the concept developed in the 40's or something ? Pretty incredible performance...interesting idea.
Jeremy Harany yes is been around for a while...look up fordson screw drive. thanks for watchin
Great job, man. Just because it broke doesn't make it a failure. Rad project.
Lol he was like....A project ive been working on for a few years now....like this hole ive been digging for no apparent reason looooooooool classic
If you ever decide to try and make it hydrostatic, look at getting a pump and some drive motors from a skidsteer loader like a bobcat, or one of those small mini-excevators. Maybe find one that has a blown engine or something.
If you add a bypass loop with a high pressure valve, you should avoid it blowing up on you too. Besides, with hydrostatic drives, you could also do neat stuff like roll sideways 'n' stuff. :)
Grumpy ol' Boot yeah i'm thinkin thats the best bet....seems hard to find a cheep wrecked one here, i've been lookin around though. sideways roll would be sweet! thanks for watchin
REDNIC79
Quite welcome, always fun to see people's creations.
Which ofcourse means I often end up in the russian part of youtube ... and *man*, they got some weird stuff over there! >_<
Alternatively, you could make it into a tracked vehicle, that could be fun too.
Grumpy ol' Boot yeah i really love some of those russian creations, people think you crazy build that kind of stuff here, but its sooo much fun!
Grumpy ol' Boothehe
Awesome project man! If i were you id start from scratch, make it longer (for stability) and structurally more reinforced, rather than basing it off a lawn mower or something originally not terribly strong. Better to design your own reinforced frame for specifically what you want for it, rather than to just reinforce an existing frame. More power wouldnt hurt either to blast up that hill too, not exactly sure what went wrong with your transmission but hopefully you can figure out the powertrain problem. Good luck and keep working on it dude!
+Greg Campbell thanks for the comments! yeah I'm still workin on the current design....the tractor has sentimental value to me :) I think you are correct though. thanks for watchin. more to come
Use larger sprocket might help
So how is it going?
I want to see more of it. Its undeniably slow but its fantastic!
🤔
I dreamed about one of those before, but never have seen one until now!
many very cool things, keep up the sweet inventions, you're doing a lot of awesome things the rest of us wish we could do, many of us are living through you, vicariously.
Screw this. Im out.
underated comment
Sorry, I gotta bolt
Hahahahaha
He screwed up
Turd trac ! LOL!!
Not sure how practical or efficient this would ever be.
But from an engineering point of view it's very cool.
Congratulations on the invention !you were creative 😎
awesome build. love the re-purposed tractor idea. have you done any sort of force analysis? just off the cuff, it seems like the shafts should be supported by radial bearings on their ends. moar bearings = moar torque capacity. you could even put bearings between the gears and the transmission
wingman358 no i have not done any force analysis, but i would love to know how. is there some kind of equation as far as augers are concerned? if i do decide to go hydraulic, it would be very helpful to know torque requirements. any insight?
REDNIC79 To determine what the maximum forces are put on the drive shafts, do this: take the total weight of the vehicle + cargo + driver, and that is the total force that the pair of augers must be able to exert into the ground. That total weight would be if you were driving straight up a wall somehow. Obviously not possible in reality, but easy to think about. In most cases, the augers won't ever need to exert that much force, but it is handy to know the upper limit. Now take that weight/force and divide by two (for each auger). Multiply by the radius of the auger, this is the torque required to turn the auger (at the maximum condition). Divide that by the gear ratio between the driving shaft and the auger, and you get the torque the driving shaft must achieve to turn the auger. Divide by the radius of the sprocket on the drive shaft, and you have the force that the shaft is putting on the chain. That force is the same force that the shaft must hold. The more force and the further away the force from the support, the stronger the support must be. In this video it looks like that support is the transmission housing/transmission bearings. It's no wonder the case cracked!
The easy solution is to add more supports and have them close to the applied force (the sprocket). So in your case you should put bearings at the end of the drive shafts. Even better would be two bearings for each shaft, one on either side of the sprocket, as close to the sprocket as possible. To take it a step further, you would want bearings on the ends of the auger shafts too, otherwise you are likely to bend those shafts.
Another thing you could do is to beef up the shafts. An increase in shaft diameter of 10% is a 100% increase in moment of inertia (resists bending), so small shaft increases result in much more strength. That might eliminate the need for more bearings. I'd recommend both though if you really want to make it killer.
I think your set up is very close to being bullet-proof. You should look at your design and build as very successful, since you were able to drive it and you did get through the flat mud. I am very impressed. The motor seems strong enough, the concept is proved, all you need now is a little reinforcing at the shaft ends and it should be 10x stronger.
does that work out? i'm thinking the resistance that needs to be overcome to turn those screws would play a factor in the torque calculation. the weight of the vehicle is a factor in that resistance but torque requirements will change depending on what torque screwing through would they not? if i was going straight vertical through a bowl of wet concrete, the wet stuff must factor in compared to looking at it as just the diameter of the screw itself. actually there is an interesting paper on the internet about it. check this out. scholarcommons.usf.edu/cgi/viewcontent.cgi?article=4774&context=etd
This looks like a great paper. I think the mathematical analysis there is lacking, but its descriptively pretty good. Good place to start.
The off-the-cuff calculation I wrote earlier was a bastardized way to arrive at an absolute max, neglecting many things such as actual inclination of the vehicle, screw pitch, submergence of the screws, friction, rotating inertia of the drivetrain, drivetrain frictional losses, etc etc. I still think it would be handy to know in a quick and relatively easy way what the approximately very worst case scenario might be, because if your vehicle can withstand that, it should be more than adequate everywhere else.
You probably don't need to do a whole lot of calculation anyways. I think you could easily add a couple more bearings and conquer the mud pit.
wingman358 yeah, its hard to say, the calcs would come into play when deciding on what hydraulic motors to use
"basically i'm SCREWED" Pun intended!
Hahaha
😆
Nicholas Cabrera Screwed X2 at the same time.
I have seen X3 before butt that's a different story
Nicholas Cabrera....wow i didn't even catch that until now... I guess i should be pun-ished

Nice try anyway, and much learned. Thanks for sharing.
With the 20-20 vision of hindsight I think that you may need to consider building some sort of frame (possibly 3/4" plate, profile cut?) to mount some support bearings on the rear end just to hold the relative positions of the axle and chain drives. This would need to be framed to the transition to stop it from twisting bodily I'm the opposite direction to the applied torque. I'm thinking along the lines of a box that the transmission and drive sits in. It would increase the all up weight quite a bit but it would give you something to mount the float tubes on and form the 'hull' of the vehicle. Like I say, easy to engineer after the fact. I think you've done a great job and love the video.
he is going to become the next villain in Marvel Comics
...meanwhile in Canada
Got a kick out of your video. We have the Razor XP 1000 and Wildcat X ATV's and we tour with them, they are tough and hold up super well on our tours.
Lol ur a mad scientist with these crazy machines. Keep it up, very interesting stuff
Your rescue machine looks so awkwardly handicapped !!
Great project though I'd try with larger diameter tanks and an direct drive dc motors at around 36 volts
Use bigger cylinders that can be pumped with water separately as adjustable ballast tanks.
Also if it could strafe left and right you could stop from getting stuck when you need to turn. Still a really cool project, keep on keepin on.
I wanna move to Canada, so that I have the time and money to build cool toys like that. Good work Buddy, keep it up.
That's a really cool project! Sorry it broke. Don't give up on it though. Take a break from it and accumulate some parts and ideas, then give it another try. Hydraulics may be the way to go. :)
sorry you put "THE END", because this concept is very interesting. Perhaps you need to dig a bit more to solve the issues. IMHO looks promising, but yeah, as you say below, money is a contraint ... bad news.
what about going hydraulic?

eory
amazing. I have only seen pictures of old ford tractors with screws.. I dont are it broke, just trying to make it work was awesome.
thanks!
