Hey guys. New video (Robot with Windshield Wiper Motors!) ua-cam.com/video/k7XKJWinG2U/v-deo.html
The Post Apocalyptic Inventor c
Nice... but tell me now,... my comments are witnessed and acceptable.
@The Post Apocalyptic Inventor: You should NOT use the brush for the higher speed setting as that is the tertiary brush you noted in the video. This offsets the rotor poles but leaves less of the winding to do more work. This brush should be removed and this connection ignored. Only use the directly-opposed brushes, as this balances the current between ALL rotor windings.
The high speed is largely inefficient, and when re-purposing these for linear actuators, this largely reduces torque. The high-speed brush is a cheap cheat to avoid using two motors in series or parallel as a two-speed control, and high motor load in this manner can burn the motor, as the "low-speed" wiring that uses the diametrically-opposed brushes provides much greater root-mean-square power than the crude cheat that is the third brush.
We used linear actuators for this robot hand.

I like this channel, and the other German guy: Great Scott.
UK here, I’m absolutely stunned that we apparently make an electrical car part that works
LOL. I didn't see the word Lucas on it.
Made in China, packed in UK, just as in USA and here in Aus.
Tina..As an British engineer I am deeply offended by your remark. UK is and has always been perfectly capable of producing high quality products. it has always been the accountants, (stupid, self centred and empire-builders), that have brought problems about. In Britain these accountants were usually heads of engineering companies. Think of George Simpson who, all by himself, destroyed GEC. Look up the history of GEC - UK and how that maniac squandered a 4 billion £ cash mountain left by Wienstock.
By contrast most large engineering companies in Germany are headed by technically qualified people. (At least that is how it was the last time I looked).
If you are looking to criticise Britain with something then it has to be the political perversity of bestowing, (or allowing to retain), a peerage to to an ass who destroyed a vitally important British company.
To address your comment specifically, Britain may not be making volume production cars anymore, (like VW, Peugeot, Fiat etc), but has lots of subcontractors supplying the volume car makers. This is why things are very worrying for those subcontractors when they contemplate what will happen to them, their workers and jobs when we leave the common market and cannot agree to a free trade deal. One guess who'll benefit...
By the way Britain designs and makes the wings of all the Airbus' and we also design and make great world beating Rolls Royce jet engines .. and take it from one who knows ... that is just the tip of the iceberg of our capabilities. And Tina ... We do stuff you just would not believe! I invite you to take back what you said - even if said in jest.
By the way TPAI: As always great video.
CamiemEngineer Offended? Engineer yourself a thicker skin. She didn't call out British engineers. I would guess Tina has consumer experience with low quality parts. The book you wrote actually explains why a consumer might be surprised when the market produces a quality part.
+ Nick M
Yes you're right I ought to grow a thicker skin. But just so you know I did personally deal with GEC as a Power Station engineer, you know .. one of the twerps, (that no one cares about - invisible ... you know the sort), that do their best to bring electricity to your home so that you can use your computer oblivious of what's behind the switch.
But its not me that you need to instruct to grow a thicker skin but instead to the thousands of engineers who lost their jobs & livelihood at GEC because of one criminal ass, namely Simpson.
Oh yes I did write a book didn't I? Well maybe it's because I am fed up with engineers and manufacturers being blamed for the actions and aftermaths of non-technical asses running major British engineering companies.
A tip for those who try this without the special splined section on the end of the worm drive. Drill a piece of flat stock steel the size of the M8 threaded section coming out of the drive, on the underside take a much large drill (20 mm should do or 3/4 for us Americans) and just slightly let it drill into the back side of the M8 hole to make a chamfered section. Then using a torch, heat the end with the hole up to bright orange (or to where a magnet won't stick to it anymore) and then very quickly force it onto the shaft and drive it a whack or two using a washer the size of the threads backed up by a close fitting deep well socket. As soon as it is down to the depth you need it dunk the drive gear and flat stock into water until it stops sizzling. This will do 2 things, first it will basically forge the correct spline and angle into the flat stock and when the piece cools it will shrink and pretty much permanently affix itself to the shaft. It would be possible to remove but with great effort. As long as the heat is only in contact with the shaft for no more than 20 sec before it is immersed in water, it won't have enough time to transfer heat through the shaft to the plastic worm drive enough to cause an issue.
That's the cheapest example of a linear actuator I have seen so far that is actually robust enough to be useful in a number of applications. I'm thinking of applications that range from a TV stand for hiding a flat panel TV to a driveway door and all the way to a small press. Btw, maybe breaking bits of wood is a bit of an overkill in order to test for the actuator's strength. A more accurate method - and also one that would put a lot less stress on the motor - would be to just try to lift a set of barbells or a large container filled with water. Using water as your weight measure enables to you find an accurate limit to the force the actuator can exert before hitting it's current limit. Great work!
Another good source of trapezoidal threads that is rugged and can be obtained for cheap are scaffolding leveling jacks. I have no clue how they're called in German, but I've used them before as the leadscrew for a wood vice.
Or mechanical hospital beds
Yup I used them as leveling legs on my portable sawmill, found them in a scrap yard.
Leandro Pereira Yep, that's actually quite a good idea. Too bad they're too thick for many purposes though.
Don't forget power seats for cars ;)
Gerüstfuss
You can find the good threads on spring compressors too. And since they come in pairs you have two of them for cheap.
those wiper motors have a surprising amount of torque
most all DC motors have a lot of torque and that's why metal lathes and battery operated drill or tools are DC. First it was all belt driven then pneumatic drive and now DC just for the torque.
The srcret lies in the worm gear. The ratio of this gear is likely somere in the range of 40:1 - 50:1 meaning the speed is reduced and the torque is increased + it is not backdriveable. The dowside is that the efficiency is probably only 50 %...
I am impressed that it can brake a 2x4; it can probably lift up a chunky baby off the floor.
Pacifico VW the reason I was impressed with the amount of torque is because I am nearly 400lbs and I need to bounce on a 2x4 to break it. So it must be able to output around that much.
Granted though my 400lbs is spread over a greater area than that of the jack.
Of course! if you count the number of teeth on the gear that is the value of amplification, bc the motor shaft makes a whole turn for only ONE tooth of advancement on the gear. That means 60:1 or whatever the tooth count is, IS the amp factor.
"made a power train with salvaged washer machine motors" I already like this guy.
I built some of the same sort of devices. While making stabilizing for my camper van.
At first I connected a gear motor to a scissor jack. Made a nice little trash compactor.
Later I used a mechanical bottle jack, these worked great on my van.
My intention was not to jack the van off the ground, but lift it enough, so it wouldn't bounce around, as I moved around inside it. Great Video, Thanks!
This is the first time I've seen one of your videos but I love what you do, your approach to your work and the way you share / present it. A while ago I saw windscreen wipers and car jacks utilised to lift a car body on a jig and to also rotate it (Bad Obsession Motorsport's Project Binky). They didn't go through the fabrication and testing involved but I'm very glad to have seen it in your video. I long to do things like this but my brain doesn't visualise or understand in the right way. I have a crate full of wiper motors and car jacks but haven't introduced them to each other. I admire the quality of your work and your resourceful mind.Thank you for showing so much of the process and where you found parts and specifics about them. I will forget a lot of this but I know that some of what I learned from you will remain and I will definitely be watching more of your productions. Good luck with your robot and I hope this winter will be a little easier on you!
I also meant to compliment the posters you have in your workshop. I love the monorail / mag-lev concept art. I love the style of illustration and the futuristic vision. Why didn't anyone make that?! Great inspiration and decoration though!
His English is better than most of my fellow American's.
not a difficult achievement, let's be honest!
Most dc motors are reversible simply by switching wire polarity.
I bet his spelling is good too
Boomers have awful grammar and spelling.
Lol he ain't American hhhhhh
Genius idea! I have finally been provided with a use for the five crappy factory screw jacks that I held on to for years and threw out last month.
N Ferraro same here, told the wife these things will come in useful someday... 😒😂
N Ferraro there's so many things that I've thrown out and then realised that I could have used them later that week. I think the trick is to make some time to look through your boneyard so that you know what stuff you have, instead of only learning what you have once you've put it in the bin.
Murphy's Law!
@@texasrox2010 You haven't been on a junkyard run in a while. All jacks removed from vehicle, none allowed through the gates. (at least in PA)
Thank you, love your videos and thank you for including german words (written and pronounced) in the video so we can learn something extra.
This channel highlights what a wasteful society we've become. If we put more into teaching people basic engineering skills we'd all be able to reuse most of what we currently throw away.
there are entire countries that do it out of necessity. Instead, we have laws to prevent people creating their own deathtraps. They are called regulations. For example, I could probably build a whole car from scratch out of random junk, but it probably wouldn’t pass pedestrian safety standards. So if I accidentally ran someone over, they definitely wouldn’t survive. If you disagree with this concept, you should vote to reduce things like public safety regulations etc.
Consumerism prevails to benefit the grand capital at the expense of Nature and Humanity...
I like repurposing "junk" that I already have on hand as much as the next guy, but to do it on a national (in a developed nation) or global scale just isn't feasible. Whatever you save in material costs you easily lose in additional labor to adapt the existing items into the new product. This process would be difficult, almost impossible, to automate because it's likely that all the used items are each slightly different from each other, which means that each one becomes a custom built item. It just wouldn't be profitable, and if its not profitable it can never happen on a major scale.
there many engineers with extremely high paying positions with far less ability than this man. If I was in a position to hire someone for a project this person would be of top shelf priority.
Yes and no....….if it's a fix it no matter what then yes, but if it's a maintenance situation where the end result has to conform to insurance standards.....DIY has no place except for the home workshop. BTW...….I take my hat off to the clever application(s) that he uses for simple solutions.
Thank you for this hugely useful video! I am considering adding a set of linear actuators to lift a sleeping platform on a custom trailer, and you have inspired me to have a go at it. I found the whole video useful! Your approach to fabrication is really great. Can you tell me what type of welder you’re using? Is that TIG?
It's interesting to explore gear ratios to move things. Wiper motor and window motors have plenty of gear reduction built in, as does the starter motor. If you play with hobby class remote control toys, you will notice the change in take off speed as opposed to potential top speed based on the pinion and spur gears used. If you discover the maximum rpm of the motor, then find out what rpm range it operates best at, then you can change the final drive ratio from the motor shaft to the other end of the assembly you want to power. If the gear on the motor shaft is small and the gears at the other end large, then the device operates slowly, but strongly. If the gear on the motor shaft is large and the other ends small, it may be faster, but less power over all.
Motor manufacturers usually have spec sheets on where the input voltage should be to create the rpm range for peak power. Learn to plan your gear ratios with that, and you will have measurable success.
I hope in the future, you will come Sider hydraulic actuators and use a hydraulic steering pump from a car, powered by a robust electric motor. Those hydraulic pumps have internal bypasses, so they don't have to create constant pressure while spinning. Then you can use small valves with small servos to open and close them to have the desired actions. I've been working to invent flexible hydraulic actuators, but those secrets I keep for now.
For a remote control steering unit, you should try the screw drive, power seat motor, like found in a late 80's Nissan Maxima (the one that moves the seat back and forth). It could work just as a rack and pinion unit. As well as open gates, and any other purpose you would use a hydrolic ram for.
50 years ago my father studied and lived in W.Germany, worked for Siemens, and he always told me that when I grow up, I should go to Fachhochschule, I never knew what he meant, until now, this dude is Fachhochschule
Totally awesome! I have a background in the machinist trade, major appliance technician, and handyman home remodeling. So I can appreciate your mechanical aptitude and mechanical reasoning. Well done sir! A fantastic idea using the screw jacks, they are extremely strong and durable, just because of the thread design. And the use of a windshield mother outstanding! I drive a Mercedes Benz 300SD 1983 with over 300,000. In line 5 cyl. turbo diesel. Its a tank! I love anything and everything that comes from Germany. The engineers from Germany second to none, just like you. I do all my own auto repairs. Being mechanically inclined you can figure just about anything mechanical. Well done sir, outstanding video and presentation.
Dude needs a Harbour Freight.
Change the worlds off its axis
I am thinking trailer or RV auto-leveling while parked.
Great idea ! I think about my heavy retracting patio shade ! Struggling with it is increasingly difficult with my arthytis attacqued hands.
I assume you already know that those wiper motors can be fed with 24Vdc for short period of times, that will make the linear move much faster. You could use that for steering or other short linear movements.
4:58 "I wouldn't recommend putting a crazy amount of axial force" then proceeds to crack 2x4's in half with it. :P How that tiny worm drive with such a thin pitch is able to break 2x4's is mind blowing. Did you swap out the gear and lead screw internally or did it break the 2x4 with the stock gear? If you pull any wiper stalk switch from a junkyard car it would likely serve as a good controller for the motor since that's the switch intended for it. So if you're in a junkyard don't just grab the motor and assembly but the wiper stalk switch too. Had absolutely no idea wiper motors were that powerful. Awesome video, great content. Thank you for the lesson!
If you understand what axial force is, you understand that there was zero axial force applied to the gear he was referring to at that moment.
Regarding the plastic teeth and how it can break a 2x4 without stripping the teeth... there is a huge reduction in both that worm gear assembly and the lead screw from the jack.
Brilliant!
I've been building... Sort of... A mini milling machine using the ACME thread and nut from a scissor jack. The jacks cost
I used a hospital bed motor for my project. Your ideas are great.
Here in balkans, we use windshield wiper motors to power the skewer for roasting whole lambs or pigs. The transmision is simple, often by chain, or by 2 gears from cars starter motor. 5+ work hours under load by an ordinary car battery.
"Long intervals between wiping..." Context is the key.
The guy in this video is not an inventor. He is a wizard
Very interesting videos.. am happy to see when a new one comes out..your work is of a very high standard..and great use of things that are all around us and not valued as they should be....hope you get the support you deserve
You have to love AC Delco "What the ACD stands for" and their push in the auto industry globally for interchangeable parts for all vehicle brands and models! It cuts costs and makes finding replacements locally easier for consumers, shops and professionals!
Wonderful explanation and demonstration of linear actuators. I look forward to more of your videos.
Many people don't have the money to solve developmental problems, so I'm quite happy to see how you overcome them using the tools in your shop. It is quite educational. Pkease keep doing what you are doing! Liked by a long time subscriber!
Very nice. You're one smart puppy. I love it and I like the German lessons as well. Just a handful of German tech words might bail me out when I'm working on some German machine and the only literature I've got is in German.
Never thought I'd see a jack that makes scissor jacks seem stable.
You are very creative. I don't know how I stumbled across your video but I'm glad I did because I've been wanting to motorized my patio door so I can let the dogs out on the patio when it's nice out and then close the door behind them if it starts raining. I have an RFD tag on the dogs which I can detect them leaving to go out and coming back in but I couldn't figure out how to get the door to function inexpensively. Maybe I will post a video of the completed project in the near future when I have time to put it all together. Thank you and I will look forward to watching more of your videos
Tom William youre gunna fuck your dogs up if it malfunctions
this is awesome ...less expensive solution ..i'm not building a robot but this would make a great way to actuate the release and brake for my winch on my log skidder
Love your ingenuity and the German lessons!
I love how what I wanted to say is already here.
cmonster6, I have to agree with you. I work with a German engineer. He's going to be all giddy when a drop a few of these German terms on him.
cmonster6 useless ! Just use a electric drill and car trunk jack done!
Hello from UK, despite driving Mercedes, I'm here for English lessons.
South Africa here
There is *SO MUCH* potential with this wiper-motor linear actuator
1) a solar panel array to adjust for the sun's angle of inclination
2) a tilt for a dump truck/trailer
you might find some motors and linkages to suit your purposes from seat adjustment motors . . . they have to be strong enough to move my fat ass so i bet they're strong enough for your robot.
[ unless you're building a terminator ]
will amoroso I was going to make the same suggestion you gave
Most interesting part to me was seeing a 3 brush motor. Never seen that before. Neat how it allows for multiple speeds. In North America, you can buy new windshield wiper motors at discount auto places for $6, and jacks from a junkyard for $5. That's a really, really cheap actuator.
I bought somrthing almost exactly like that from autozone for $15 us. It was clearence so i bought two and they are awsome!
I know this is a couple of years old but I was wondering if you tried to run the wiper motor in reverse. Seems like you need a motor that can be reversed to make this actuator practical.
I know power window motors can be reversed and are pretty powerful. You could also get more speed with a engine starting motor but I don't know if you can find one that is reversible??? If not, it may be possible to use an old ratchet mechanism and connect two motors that turn opposite directions to achieve powered movements in both directions.
Great video! Take Care and be safe, John
Too much work! I use a cordless drill to operate the scissor jack.
Al Carey not as much power and you kill your drill motor in doing so.
Lol I do the same thing 😂. BUT I made this anyways cause its fun for me.
I do the same thing but make sure the sucker has enough power or you'll burn it out quick...:)
@@Aussiehomestead1965 Some years ago one of my friends in the model club used to make DIY wheel chairs for kids on low budgets using two windscreen wiper motors to drive the back wheels. Using these 12 volt motors is all about gearing down the motor to increase the torque etc.
Awesome instructions, thanks. The motor on the red jack should have been turned 90 degrees so it would be out of the way when jacking and add a cigarette lighter plug to the end of the wire with an on/off switch by the jack then it could be kept in the car for flat changes.
Pinter banget !
thanks (Terima kasih)
Thank you for another video. They are always great
lol, i wish my workshop was 16 degrees.... its 8.... on a good day... nice work with the actuators. has given me some ideas
It's kind of annoying that manufacturers get away with pricing Acme threads as they do considering automation has pretty much removed any of the issues that plagued it back in the day. They make them just as easily as they make normal threads. But because they look different, you have to pay extra.
Economics of scale. Compared to normal threaded rods none really needs a lead screw.
aserta it is a different operation, so overall scale comes into play. Standard bolt threads are made by the billions, but the Acme type are much less common, thus slightly more expensive
pach maseen
+aserta Acme threads are cut, and then typically ground to a fine finish. Threaded rod is rolled with a thread die. The finish on threaded rod depends solely on how worn out the die is. If you can figure out a way to roll Acme thread that is precise as cut and ground thread, but as cheap as threaded rod, everyone will be begging you to take their money.
+Interstellarsurfer ACME threads are actually rolled. Its much faster and the cold forming creates a stronger thread.

If you get a couple of old school mercury thermostat control tubes, make four of these, and do a bit of fabercobbling, you could make a self-leveling camper/rv setup, or just a neat table
This is my new Favorite Channel!!
Watching in 2021, as I want to make an air pump for my pond and need to concert rotary to linear. This is a great video, better english than most native speakers, and lacking the normal obnoxious music and fast cutshot editing. Subbed!
Briliant video!
You are great!
I use to work in a glass shop and also worked on cars, anyway , you might look at using door window motors, they have lots of power as well
Great video. Do you know of any wiper motors that dont have plastic gears? I would guess that would be the first thing to fail after a lot of use or torque
I would bet if you got a motor off an older car there would be no plastic. Ask someone at a car salvage yard about this . Preferably an older employee who has worked on older cars.
crzy11000 older cars generally are metal gears, you're right.
I believe that may be the idea sort of a shear shaft or weak link so the damn thing doesn't tear itself off the mounts if it binds up.
The trapezoidal screw takes most of the shit and abuse. If you think about it the jack holds its own if you stop cranking and remove the crank it doesn't transmit any force to the stub; therefore the force on the motor whether plastic or not is minimal.
Howard Black a
What a treasure chest of knowledge. Mr. Inventor you are amazing. Thank you so very, very much!
One thing about 12V motors: they are easily switchable from forward to reverse. I did an automatic tambour and used the motor out of an old dewalt drill with a couple of dpdt limit switches at the ends. When it reached the top, the relay cut off the power and reversed the leads so when reactivated to lower it, the motor had power, only in reverse. Then when it was time to go up, the lower limit switch reverse the polarity again and allowed it to go up.
Great video on sourcing a useful motor/drive train. I bet you could get them even cheaper from an auto recycling yard.....
Muskoka Mike That’s similar to some post war model trains I got from my great grandpa. It has a kind of relay that switches directions every time you cut power

Look into a waste oil heater or a wood burning rocket stove for heat.
My shop is not done yet and right now it is 16F or -8.9C in it.
I am not sure what I want to build but the waste oil heater could be my best option.
No carrying wood all the time to re-stoke the fire with.
3:20 Just the tip, mind you, and only for a minute. I promise!
Focus you fack?
The Jack let the shmoo out
Its only smellzz
Nice.
Shes toighter than she looks
Very interesting and inventive prototypes from easily obtainable auto parts! I’m very surprised that the motors can continue under such great torque! Thank you!
😂😂😂Gewindemuffe M8 30mm... Wie geil das klingt
Cool channel, just came across you today. I have a stack of motors and gears I've saved out of various machines over the years. I love lighting and use them to create moving lights. I am also a robotics fan too.
New subscriber here from North Wales UK :)
i love the 2 posters we see at 20:40
where did you found them?
TheCrazymicki greatest videoyouve give especially omegoodideas.
They look like old Popular Mechanics posters.
Just found your channel. Very impressive and informative. Great teaching channel. Thank you.
Great to see a new video.
Does that scissor jack lift a car? It would be cool to have an electrically operated jack to change out a flat tire. Nice projects.
Habe eine Video Idee für dich:
Kauf dir nen Auto vom Schrottplatz (für so 200 - 400€) und Baue dort alle möglichen interessanten Sachen raus ... Bau zb nen Windrad
rcbot original "Kauf dir nen Auto vom Schrottplatz (...) Bau zb nen Windrad" - ".....war, war never changes." :D
SWEET! have been wanting to build automated 'follow the sun' mounts for solar panels... purchased linear actuators are stupid expensive!
Power seat from a car has the threaded rod that your looking for. Also has motors and switch all right there. Going to get one to make a bed cover lift.
That is so clever you make youtube a great research reference point, really appreciate your strong knowledge base and attention to detail
They make these for campers. Electric camper Jack. Probably no plastic. Definitely strong lifting power.
Wouldn't that entire windshield wiper rig from the beginning of the video make the perfect steering setup?
I have an idea, use those Arms for your Steering Bot Project !!! OMG, you can use the Motor for that too... CHEAP and effective !!!!
I like the idea of using washing machine motors to make your own electric car.I may need a really really long extension cord tho
This man is way above my current aptitudes & capabilities. Whereas this is true I do find parts cleanup with gasoline & an old rag to be (for many)quite hazardous. In my work we often use citrus de- greasers which are very effective & less combustible. Certain powdered hand cleansers I have also used which are water soluble yet cut grease & dirt amazingly well
Hello from England. It's cold here too in our unheated garages. We just put more clothes on and drink cups of tea, or use those horrible gas heaters that take the 15KG propane/butane cylinders. We also like to complain about the cold too :)
Nicely done. Looks like I need to build an actuator for my gates on my property, then figure out how to make them remote somehow. Thanks for the inspiration. SUBd
this is fantastic. the scissor thing is exactly what i was searching for.i will have to adapt it for my build a bit but thats not much. love it. thanks.
I am building a custom delta style recumbent tricycle...i am constantly scanning youtube for cheap part alternatives....the windshield motor here just gave me the parts idea i need for a drag link on my build..from the fork to the handlebar mount 26" behind it...just saved me 40 dollars for a custom drag link
The welder glow can keep you warm 👀🤣🤣
Cool. Going to use this idea as a actuator for a Solar Tracker.
What’s a solar tracker?

Very useful information, and your English is excellent. Thank you!
Argon can be expensive to refill, here in Canada we pay quite a lot for it, so I switched to flux cored wire. Sure it stinks, so you make sure to have ventilation and a filter mask can remove the worst chemicals, but it welds nicely, a 10lb roll lasts a very long time.
This is a very cool video. I would very much like to see it working with the limiting switches. Great tips here about the different wiper motors and jack available. I appreciate it very much.
M16 metric threaded rod.. I used that for a gate closer and it's worked for years.
I have a lot of experience with windshield motors. Used them on a robotics project 17 years ago when it was not possible to order a linear actuator in my country.
One quick suggestion on the connection. File the sides of the motor with the spline flat on two sides of the spline and use a nut to secure it. The threads are not the best for transferring the torque. If my description is confusing I can upload a video of one I did. Let me know.
Those BTS7960 H-bridge modules might have some manufacturing issues. @scanlime used some in her winchbots, and she cleaned them up by removing the heatsinks, making sure to remove any solder splatter on the PCB, then adding some thermally conductive tape between the PCB and the heatsink (since it has poor thermal contact by default).
Thanks for your very clear video and verbal explanation. Money saving idea. I'll use these on my sun-tracking solar panels.
Very cool. You gave a great idea to solving a project I am doing. Rear wheel steering on an off-road vehicle. A small winch and some larger acme thread. Thanks !
you tell us every thing except how to reverce it I would like to make one of these for my snow blower the regular actuators are very expencive here and your ideas are awsome
Alan Seager reverse polarity
Really like how you make use of other common items for projects, without going out to buy $$ expensive parts.
I need one of these to get me out of bed in the morning !
I've only just started watching the video but I like the idea of using a small motor to actuate the car jack's mechanism
Very encouraging tutorial. I want to convert my manual winding jacks for my lift off canopy on my ute and don't want to spend $1k on brand name jack conversions. 1 motor and gear drive with a 14mm socket on each motor for the jacks to wind up at the same time all wired together (or battery powered like a BBQ rotisserie) to one switch would be great. I thought a wiper motor or window actuator with up down would do but I don't have welding skills or equipment. Any ideas on who to talk to about this in Australia would be appreciated.
Keep up the good work.
Thank you for sharing ur brain with the world.
ha......even with a plastic gear, the wiper motor still lasts a lifetime. I'm impressed! ! !
I was expecting all metal gearing.
That electric car jack is an awesome idea though, I wonder why nobody does not make them as aftermarket.....
They do. Try Google image search: Electric car jack
lol.....I've been living under a rock.....
Tap a hole through a block of steel - a wide nut. Use a power drill to spin a threaded rod to move the block up and down. You could use nylon for models.
On a practical note ... In my entire life I used a car jack less than 8 times. Most likely spent less work in cranking than building a power actuator.
Thanks for the connecting idea onto the M8 and splined driveshaft.
Love your tinkering projects and like you it is to cold at the moment in my mini workshop in the UK. I am more into machining though than tinkering. Your English is brilliant and I am sorry to admit my German is non existent.
I am glad I found your channel. It was probabley about a month ago. It is interesting to watch your idea's and concepts turning into a reality. All the best. Cheers.
Try using bilstein Jack's for your linear actuators. Very smooth and powerful. I'm surprised you didn't try this since they are built in Germany
