3/8-16 is in your left hand (right side of video), 3/8-24 is in your right hand (left side of video - threads per inch --> higher = finer)

It's nice to find videos that don't just tell you to buy expensive things.

Thank you for clarifying this, never took the time to notice the difference! Please keep up with producing these great videos.

Great job! Concise, clear, and well-produced. Thx.

Amazing video an explanation!!

Thanks for this. I watched two videos before this to try and find out what a lead screw is but I was none the wiser. Now I think I understand

I was looking for that explanation !!!. Thanks

Very well explained.

Great explanation. Thanks for taking the time to make the video.

such a great video! Execllent explaination

Could you make a video comparing stepper motors, vs geared Dc with lead screws? i think the main variable would be torque. And also, how can you determine how much torque would your application would be needing for selecting neither a too powerful, expensive and heavy motor nor a smaller, cheaper that does not do the job.

Hello, i have made a cnc frame 40 x 60 cm wide with v slot aluminium profiles, have mounted 16mm rods and bearings and a router trimmer. Wanted to ask: for this cnc frame size and 16mm rods and bearings: 1. what thickness of lead screws should i use and 2. which is the smallest stepper motor that i can use ?

hi great video ive just up graded to Stainless steel lead screw 2mm spaceing from m8 thread do you know the settings on a 3d printer stepper motor?

Thank you! Now i understand the difference.

Thankful

Hi, I have a question for you that I hope that you could answer. I have seen a type of threaded Rods under the piano stool to my wife, and it has a very interesting mechanism. When you turn the nub that is attached to the threaded Rods, to bolts that are placed on the threaded Rods go in opposite direction, so I wonder whether you know the name of this type of threaded Rods? Thank you very much!

Hi, thanks for the explanations. Which components do you have / recommend for mastering backlash on the lead screws 4 start or 5 start? And what would be best precision to achieve?

Where can I buy the large pattern plane that you are using in the linear actuator? Seems to be around 7.5x4.5" with 8-9 holes.

Thanks a lot for your help! Im creating an industrial bakery machine and found this very usefull for an adjustable height workbench where the main machine will stood on. Understood that lead screw are more efficient because its has been manufactured more preciselly and therefore I'll have less friction and less energy converted to heat to reach better performance in terms of translational speed and force of the screw (you correct me if im wrong) and also in EN system, the greater the pitch number, the slower will be the translation because it has to create more revolutions to translate 1 inch. Also reacting to some comment around here, this principle of screw mechanism is very usefull in the industry and are the basics. Its like the slider-crank, cam-follower or the clasic 4 bar mechanism with revolute joints only. Dont delete the video.

Hey, i wonder how far the nut of the lead screw moves by rotating it 360°. So I just need the distance per rotation. Edit: I found out that the english term of it is "lead" or "lead of thread" and it is 8mm per rotation. Is that right?

What is that frame/ plate you use?

was none the wiser after watching this. from what i know there are ball screws and lead screws. is a threaded rod a type of lead screw?

No talk of speed. It looks like the speed of the screw action would be faster than a normal threaded rod but I guess we will just have to assume that. A side by side comparison between the two rods would have been good...

Where can I get a threaded nut for a threaded rod like you would for lead screws. I was having a look at your m8 round screw plates and was going to buy one until I saw shipping to the UK is $59 for an item that cost $4

Can a threaded rod still produce that linear motion even though it is less efficient than a lead screw?

@servocity Can you do a video on picking the lead screw based on project needs? Thanks Great video!

Does lubricating a lead screw make any difference? Thanks for the great info.

What does , lead screws have 4 threads mean ?

Video begins 03:40

is best resolution and any test this in 3d printed

"inch" ... imperials ... ;-)

"Lead screw thread" lol Didn't tell us a single thing about lead screw sizing or thread type nomenclature

maybe one day americans will start using the metric system !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You need to delete or remake this video.. for a 4 minute video your teaching skills are non existent.. i watched the video and all i know is a lead screw is the best for anything non structural.. Thanks
