Thank you so much! I am very glad that people like my projects. I will try to do interesting projects further.

I've been looking at this motor recently. Looks similar to the ones you guys have been talking about.

Sure its similar - but smaller in size with a 50 max rpm and 60w continous output -Quote:

Its non-cheap price tag and "Makermotor" brand sounds to me like it's intended for the Arduino lot/ Robot making crowd.
A (no-load) 50 rpm motor with 4,4 ft-lb starting torque will eventually get the jack up,
but it'll take some time and probably complain a bit when the fully loaded scissor is at its bottom,
where the screw, nut and its bearings is at its highest stress and the jack has its max lift/ turn.
For the cost of this Makermotor alone you could get a 2 times as powerful, complete electric scissor jack at a FleaBay discount,
but then you wouldn't have a DIY project...:)
Added: Most 2,5 ton electric jacks available of FleaBay etc has a 100-120W motor and a 15 A fuse -
giving a max momentary input power of 200 W.
I've found none of these listing the full height & load lifting time (nor the motor's rpm),
but a few reviews state "within a few minutes"...
If you choose a low watt & lo rev DIY solution - there's simply a time penalty to pay for any given load,
(if it'll work at all) as there's simply no free lunches here either.
YMMV - Personally I'd rather visit the local scrap yard for a heavy duty hi-tork piece with 200-300-ish rpm for a mere 10 bucks.

I just wanted the motor to work 12 Volts, and not from 24 volts, since the car has only such a voltage.
I found

it has a power of 100 watts, but it is also 24 volts.
According to your advice, tomorrow I’ll go to the warehouse of old cars, try to find a motor there.
Using this gearbox from the angle grinder and the wiper motor, i began manufacturing a small winch for lifting a motor boat ashore. I hope to post a new video with the tests soon.
Lately I have been getting a lot posts with videos no longer available. Yes, they are usually 4-5 year older threads! If they have a YT link I can usually find the video there. However, many of these videos are only published on HMT and are re-posted by Jon years later. Do I have a setting wrong on my computer like "history off" or sumptin like that? What should I change?

Some of the videos are removed from YouTube. In the case of this thread, that looks like what has happened. If a video isn't displaying in a thread, but it IS displaying on YouTube, then that is probably due to some incorrect setting on the device you are using to read the thread.
Thanks, John. I'll try some different security settings in my browser. Its clear this video is no longer in the public domain. I'll see if it happens again with videos that are still published.
