[@kennethkustren9381]

Nice... but tell me now,... my comments are witnessed and acceptable.

[@prometheus575]

@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.

[@camiemengineer]

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.

[@walkingweapon]

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.

[@camiemengineer]

+ 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.

[@southronjr1570]

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.

[@brandonlemonds7593]

"made a power train with salvaged washer machine motors" I already like this guy.

[@Stelios.Posantzis]

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!

those wiper motors have a surprising amount of torque

[@whydahell3816]

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.

[@MartinElmo]

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 %...

[@pacificovw9522]

I am impressed that it can brake a 2x4; it can probably lift up a chunky baby off the floor.

[@Falney]

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.

[@jesscast5122]

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.

[@metalmoto]

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!

[@aserta]

You can find the good threads on spring compressors too. And since they come in pairs you have two of them for cheap.

[@magpieblue]

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!

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!

[@TM-dh2xb]

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.

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.

[@Robnoxious77]

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.

[@carlosmejia5728]

Consumerism prevails to benefit the grand capital at the expense of Nature and Humanity...

[@TM-dh2xb]

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.

[@mindthependulum6245]

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.

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.

[@superdau]

Economics of scale. Compared to normal threaded rods none really needs a lead screw.

[@markdoldon8852]

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

[@kailashsonar7060]

[@interstellarsurfer]

+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.

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.

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.....

[@javalos8423]

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 !

[@TopDedCenter]

You're already doing better than most germans. You actually wear your welding glass instead of hold it. Wish i had some spare money, i would send you a nice auto-darkening jackson welding helmet from the US.

[@stephentayler1414]

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.

..COO-L!..(AS ALWAYS!..FANTASTICHE....MUCH FOOD FOR ENGINEERING THINKINGS!..

[@daviddowell1353]

Thanks for the gate idea i like u have a surplus motors I have had a wiper motor since the year 2000 from a 1963 ford I was working on a paddle style fan in the garage but its loud. But the gate idea i like for this

[@waltschannel7465]

WONDERFUL video. Thanks for sharing your experiences with all of us.

[@codymoncrief2128]

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

[@MACLADILLY]

Great video, thanks. Considering a 12v linear actuator with a photo sensor switch to open and close my chicken coop door!

[@KAYAPOGAN]

Fantastic! Really good work, clean without blablabla! Don`t stop!

[@AndyMcGeever]

M16 metric threaded rod.. I used that for a gate closer and it's worked for years.

[@jaaasgoed]

Wouldn't that entire windshield wiper rig from the beginning of the video make the perfect steering setup?

[@MrSpot41]

I need one of these to get me out of bed in the morning !

[@JasonTheMunicipalMechanic]

Those are nice uses for wiper motors

[@MRrwmac]

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!

[@rapunzeleh546]

SWEET! have been wanting to build automated 'follow the sun' mounts for solar panels... purchased linear actuators are stupid expensive!

[@scorpnz4433]

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

[@donaldripper3354]

Thanks for your very clear video and verbal explanation. Money saving idea. I'll use these on my sun-tracking solar panels.

[@dehydratedwatr]

What a treasure chest of knowledge. Mr. Inventor you are amazing. Thank you so very, very much!

[@laernulienlaernulienlaernu8953]

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

[@Orlena2525]

They make these for campers. Electric camper Jack. Probably no plastic. Definitely strong lifting power.

I'm re-watching TPAI during the Covid19 lock down. Anyone else?

[@americanpirate2091]

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

[@jjaus]

It would be cheaper for me to buy them complete. I would wind up in hospital if I tried this, but it's interesting nevertheless.

[@JohnDoe-pv2iu]

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
