Really interesting. And great job with that cutaway!

Very lucky to have a salesman's demo model! I understand that they are rare and much sought after by serious tool collectors. 👷

Another satisfied customer here in finally understanding how this thing works. Great explanation and demonstration, thank you very much for the sacrifice! Cheers!

Well, thanks for answering to one of life's mysteries! Often wondered how these work, now I know.

I really enjoyed this video. Thanks for taking the time to make it.

When I first saw the cutaway, I was tripping out. "Salesman's edition" comment made me laugh a bit, too. Thank you for dropping scholarship on us.

Thank you very much for making and showing the cut away. I had wondered for years how these things work and now I know.

Excellent performance with the cutaway, Mr. Pete! Thank you! Now I do know, how it is working.

Wow! You explained that SO WELL! I have no questions.

Mr Pete, you are the ultimate "You Tube Shop Teacher"! Thank You so much, and "Happy New Year" to you and your family.

You're a master at explaining things, and you've got this video editing perfected. The place where you sped up the action and snapped it in the vice a few times.

The cutaway was a wonderful idea! What a great "just because I can make it" project this would be! Thanks Mr. Pete, and a Happy New Year to you!

Excellent demonstration with the cutaway. Thanks

Great demonstration as always. Thanks Mr. Pete

this is one of those things I didn't need to know, but now I'm glad I do. Nicely done video, especially the cut away view. Thanks for posting

by far my favorite what makes it work. Great explanation

Love that cut away. The soft points is a design feature to make it easier to sharpen!

Thanks Mr. Pete an excellent job as usual.

Excellent explanation and demonstration with the cutaway. It is exactly what I was looking for.

This is exactly what i wanted to learn from these tools, amazing job, thank you for that

as ways thanks for the clear explanation. I've used one of these for years and never did stop to think of how it worked its magic.

Thank you so much for this video. I can't tell you how many times I've taken these raskels apart to clean and oil them and in an effort to discover how they work. You answered my questions.

That was Neat to see the cut away.!!!...I have the Harbor Freight one and as soon as I got it home I took It apart to see how it worked and enjoyed learning something new

Just bought my first center punch today, and this video randomly popped up. Thank you for making this.

MrPete, your timing is incredible! About a week ago I was at my desk wondering what makes those punches work...Yep took it apart. Went so far as to turn one of the "Pistons" without the taper...You guessed it, didn't work...AHA! (experience). This is the third time you have done this to me! Keep up the good work! PS I always watch the ads, small price to pay considering what I get in return. Thanks again, Bushings Ron, Upland.

Thanks for doing that cut away. I have had a couple automatic center punches over the years and now I can finally understand how they work. Thank you for Another outstanding video.

Brilliant demonstration, thank you for sharing

That is NEAT! Thankyou Mr.Peet.

I use one of these to take out rivets and often wondered how it works. You explained it well.

Thanks for this video. I found an old center punch at a garage sale and now maybe I can make it work again.

tumbs up to mr pete and a happy new year

Very informational and thorough, Thanks Pete!

Fantastic video. Couldn’t be any better. Thoroughly enjoyed it sir!

Nice cutaway. When I got my first automatic punch it didn't work very well, so I took it apart, saw the bent spring, and promptly straightened it.

Mr. Pete PLEASE show more guns in your videos, we LOVE the gun stuff! Great cutaway and looking forward to the center-punch build!

Very interesting and the cut away was great. Thanks so much.

Very useful video! Helped me out in troubleshooting my broken punch. Thank you.

Great video. Thank you for such a clear and thorough explanation.

Earlier today I found myself wondering how an automatic center punch worked. Thanks so much for clarifying it with the cut out. Fantastic!

Fantastic Video & Cutaway. Keep up the great work. Nick.

Most edifying as per usual, and as per usual, thank you for taking the time, for my part your videos are very much appreciated.

Great video!!! Although I too have several of these including a Starrett, a General and a Horrible Freight model, I wasn't sure how they worked. I have taken them apart before but never studied it well enough to figure out how it worked. Now I know.

Great video and an excellent cut-a-way! I've always wondered how those things work! Thanks!

Thank you Mr. Cain for the "All I ever wanted to know about center punches" video. I had one that had quit working, I took it apart and found the hammer was in backwards. I probably had it apart for one reason or another and didn't get it back right. Thank you sir for your easy to understand illustrations.

Now I know. Thank you for sharing.

A simple yet ingenious device (to me) I have wondered how these worked ever since I purchased one many years ago. THANKS ! Looking forward to many more 2017 videos. Happy New Year

awesome job. I came across this video looking for a diagram to put a punch together that I had bought and taken apart many years ago. thanks for helping put it back together and for the excellent explanation salud!

Love the cutout and explanation; great job!

Been using these things for many years, never understood how it worked till now. THANK YOU Sir!

Thanks Mr. Pete. Very informative.

Thanks so much Mr. Pete! My son is training as a machinist and I put one of these under the tree for him at Christmas! Now I know how it works! All the best for you and yours in 2017!

Mr Pete great video and i love the cutaway and the off center spring.

great video, came here looking how to reassemble one my dad had brought me from his work in parts and ended up subscribing, looking forward to more high quality educational content like this, love the cutaway by the way

This helped immensely. I appreciate your time and sharing your knowledge. I'm going to be watching more. Thanks!

I love my automatic centre punch! Thanks for sharing your collection :)

Thanks for the cutaway, that makes the mechanism very clear.

Thanks for a very clear explanation how these work. I have wondered how they work since first buying one many years ago. Happy New Year! Lonnie

thanks so much, i always wondered exactly how they work. very useful in the shop of course.

Well now that was neat as hell,,,, I really learned something on this one. Thanks Mr. Pete.

Thanks for taking the time to make a cutaway and a video, very interesting and well done.

I like your cut away. Very nice demonstration.

I've waited 50 years for this! Haha. My dad has one, and I used to goof around with it. As usual, once you see it it's simple. But before you see it, it's an invention to be discovered.

This is one outstanding demonstration! Thank you Sir for sharing your expertise and your experience!

Always interesting, ever informative. Thank you.

Thank you, I've been wondering about this for years.

Always love your cutaways! I have a Lufkin automatic thats identical to starrett. Just a beautiful well made tool!

fascinating thanks Mr pete

Great video, I really liked seeing the cutaway. I'd very much like to see you make this as a project. Thanks for sharing.

Brilliant !!! Thanks so much for making this video. My cheap unbranded one had stopped working and although I had it in bits, I couldn't fathom out how it works !!!

Exceptional video. Probably the best explanation of anything I've ever seen. Thank you.

that was an absolutely beautiful video, thank you very much

Thank you. The cutaway is great.

Really great video！Thank you Mr Pete😊

I love the cutaway, thanks so much for doing that and showing it!

I enjoyed the video. It always amazes me how human kind is able to create such useful tools employing simple principles. The cut-away was a great idea. I also like how you refer to yourself as the KZfaq shop teacher. I have many fond memories of shop and regret that today's schools don't have it any more.

Excellent explanation, sir - thanks very much!

that's pretty cool. I'm seeing parts inside that I can use for other projects that are likely cheaper to salvage or Rob from a new punch than to buy or make the part. I enjoy these and all your videos. the Lord will continue to bless you for all your unselfish acts of sharing. your my favorite shop teacher.

that cutaway makes ALL the difference in the description. fabulous, and thank you!

Pretty neat indeed! Thank you so much for this thoughtful piece.

This things have always puzzled me. Sometimes they work, sometimes they don’t. But after watching your video I finally got it! I just went back and fixed the ones that didn’t work. Thank you so much!!! 👍🏻

I just stumbled across your video on the auto centre punch and I am glad I did. Your explanation on how it works was clear and concise. Plus you know how to shoot good video to make all the parts clear without half a head in the frame blocking the view and the audio and your voice is clear. Those of us from Oz had no problem in understanding what you were saying. To top it off you had obviously prepared the points (no pun intended) you would cover plus went to the trouble of making a cut away version so we may observe the interior in action. Finally I learnt something new (knowledge is always a bonus to gain) on the way the punch works. Good work - I have subscribed.

SUPERB EXPLANATION ,IT'S TAKEN ME SO LONG TO FIND WITHOUT THE B S THANKS TONY T

I just found this channel. I'm so glad I can now watch engineering videos and listen to Johnny Cash at the same time. Subscribed!

I really enjoyed this video mrpete. Last week I acquired my first non harbor freight automatic center punch. I rusted shut Starrett. Took it all apart cleaned it up and got it working again like it did in the 40's. But I was curious on how exactly it works. Now I know thanks to my KZfaq shop teacher. Thank you.

This video is very helpful. You did a fantastic job with explaining and showing how a center punch works internally. 👍

Pretty neat alright, I never did know how these worked, I do now thanks to this fine video.

Just the video I needed I took mine apart and did not think to make a video of it and forgot where the ball went. Now I know I guessed correct and got it back together correctly. Thanks

That was excellent Mr. Pete. It's always been a mystery to me. Mystery solved.

Awesome video! Thanks for making it!

Excellent demonstration! I like your whole "what makes it work series", and all the cutaways you do, but this has to be one of the best ones ever. No amount of description would be as good as seeing how it works for real. One can see it very well in this video. Thanks for making it!

Thanks now i know where I went wrong on the one i made offset spring good job Mr. Pete

Great video mr Pete! Thanks

Nice cutaway action video!!! Thank you!!!

Thanks Pete I always wondered how those automatic punches work

Thanks for uploading - very interesting!

Great video. I have a matco tools punch that quit working years ago from internal rust. I took it apart and couldn't figure out which way the parts went. With this video, it helped me understand the principle of how it worked. I just got it back to working order. Thanks 😊

Fascinating information and great cutaway!

Four years old as I watch this for the first time. Very interesting and entertaining as well.

Very informative. I retrieved one I had that never worked and found it was not assembled correctly! Thanks for the video.

Excellent many thanks for sharing. A very Happy New Year to you and yours. regards from the UK
