Well, thanks for answering to one of life's mysteries! Often wondered how these work, now I know.
Really interesting. And great job with that cutaway!
I actually expected it to have a mechanism similar to ball point pens for some reason. I was surprised to see how simple it was even though I have taken my own apart before. The off-centering spring is not immediately obvious!
Nice to see you here, Love your vids btw, and eager for more What The Infrastructure, Cheers Grady!
Thanks for watching--glad you like
Practical Engineering hey, it's Grady
@@Keith_Ward Yes, that smaller spring was offset deliberately by the manufacturer to keep the driving rod continuously offset until it arrives at the tapered cone, that aligns it with the hammers centered hole to fall into, that allows the large spring stored energy to drive down the hammer to the end of the hammer hole that drives the driving rod to the punch rod that drives the tip of the punch rod into the (metal) material.
Application wise, I am going to use one of these auto punches to punch holes into the heads of two designed shear off security screws used to attach an ignition switch lock. The auto manufacturer tighten these special shear off screws where the wrenchable part of the screw top shears off deliberately so no thieves can unscrew them from the steering column. So I'll use this automatic punch to put a punch point directly in to + the center of the very small sheared off head of the sheared two screws and then a very small drill to drill a 1/4 " hole deep and finally use a "back out" drill that bit has left hand turn cutting swirls as opposed to right hand cut that normal drill bits have, which digs into the drilled hole to the left and finally "Back outs" the sheared screw. Then I can take off the old faulty worn out ignition switch lock and install the new one without having to use an angle grinder w/diamond saw it off or hacksaw off.
Another satisfied customer here in finally understanding how this thing works. Great explanation and demonstration, thank you very much for the sacrifice! Cheers!
Very lucky to have a salesman's demo model! I understand that they are rare and much sought after by serious tool collectors. 👷
That wasn't a salesman's demo, He made it and just said it was.
Earlier today I found myself wondering how an automatic center punch worked. Thanks so much for clarifying it with the cut out. Fantastic!
Glad you liked 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.
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.
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.
Been using these things for many years, never understood how it worked till now. THANK YOU Sir!
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!!! 👍🏻
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 😊
Glad it helped
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 RUclips shop teacher. I have many fond memories of shop and regret that today's schools don't have it any more.
just got out of school and got a job as a machinist, so i get to do it every ingle day and get paid. you cant beat that
I must say thanks for this video. I have an automatic center punch and for the longest time that wasn't working properly. Someone borrowed it took it apart and didn't put it together the right way. Well after watching your video I put it together the right way and now it works just like new. Thanks for sharing!
Glad it helped
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.
I really enjoyed this video. Thanks for taking the time to make it.
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.
Thank you very much. An astute observation of the efforts I go thru to make videos.
Very gratifying that you notice all this----and take the time to tell me. You have just greatly encouraged me.
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
Exceptional video. Probably the best explanation of anything I've ever seen. Thank you.
Wow, thanks!
I don't care what anybody else says but dry firing a revolver doesn't hurt a thing. A semi auto handgun is a little different but can still be dry fired occasionally with little detriment to the weapon. Keep up the good work , love these videos!
This video is very helpful. You did a fantastic job with explaining and showing how a center punch works internally. 👍
Thanks
Thank you so much for this still being up…! I found a Starrett 18-AA I knew it was a quality tool but it was nasty and rusted I cleaned it up and couldn’t figure out why it looked to have moving parts. Now I know and I was able to put it back together the right way and it works beautifully! Thanks again
👍👍
This helped immensely. I appreciate your time and sharing your knowledge. I'm going to be watching more. Thanks!
👍👍
Thanks Mr. Pete, your cut-a-way auto punch & patent drawings helped me to diagnose & fix the angled pin tip (sanded flat) & hammer hole entrance (sanded flat). Once reassembled, it worked perfectly! I litterally pulled the defective HF punch out of the metal scrap pile! 3 out of 4 HF cheapy brass models have failed to work for me. Now I can repair the others when I find them. Thank you Mr. Pete! Paul from S. Central Texas.
Nice work!
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 RUclips shop teacher. Thank you.
Great illustration and excellent explanation. Thanks
You're very welcome!
I love the cutaway, thanks so much for doing that and showing it!
👍👍
SUPERB EXPLANATION ,IT'S TAKEN ME SO LONG TO FIND WITHOUT THE B S THANKS TONY T
Thanks
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.
I lost a good one and replaced it with a cheapo. I opened it and it has rarely worked since. Now...informed... Ill try sorting it out. Thanks Lyle...I scratched my head a long time on this!
i got my first auto punch, when i was 8, i am 43 now... used it to put a dot over the M on all my craftsman tool. works great for identification and unknowingly stickey fingers... still got that tool set today... great job on vidio, a million thanks sir...
This is one outstanding demonstration!
Thank you Sir for sharing your expertise and your experience!
You are very welcome
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.
Mr. Pete PLEASE show more guns in your videos, we LOVE the gun stuff!
Great cutaway and looking forward to the center-punch build!
awesome video. we do appreciate that you do try to appeal to a larger audience, I see a couple of comments trying to demographically profile us all, you get a lot more respect from me for being a little less triggerhappy than many on youtube. thanks for taking the time to show us this.
Thanks Emma. Not sure what LESS TRIGGER HAPPY means? Keep up your great work over the pond.
Brilliant. What a really great and informative video. I took mine apart to clean it as it was very oily and full of iron filings etc and stupidly broke the cardinal rule of not looking as I took it apart ! It now works perfectly and I have learned how it works, I have often wondered!!! Thank you
👍👍👍
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!
Fascinating and enlightening! I fell down the RUclips rabbit hole looking for a way to repair my cheap punch which is intermittently failing to fire. When I started, I had no idea how they worked but thanks to your skill in not only knowing how things work but being able to impart that knowledge clearly, I am am a much wiser and happier man :) Thank you and best wishes from Warsaw, Poland
Thank you, Stephen, glad you liked it
This is exactly what i wanted to learn from these tools, amazing job, thank you for that
Professor Pete you are awesome remember I made one to give to my Grandpa when I graduate, a center punch and a hammer, which was in 1963. Thank you for showing to the yang that watches your channel. Have a good day Sir.
Thanks for watching.
Excellent demonstration with the cutaway. Thanks
This was great. I found a heavily weathered Starret 18B punch on the side of the road by my yard and thanks to this video, I was confident enough to take it apart, clean it up, return it to working order.
Do you wonder, how did it ever end up at the roadside
mrpete222 Sure, and your guesses would be as good as mine: fell out of a truck, tool belt or toolbox. Wish I took a pic of what it looked like before... it had been in the weather a while.
Maybe tossed out of the window of the getaway car…
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
+B Kailua I like to take pictures when I disassemble something
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!
If it skips like mine enlarge the hole 1/32 that the pin goes through to the hammer.
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.
this cut away was even better than the bicycle one. probably the best explanation method.
I am thinking I might want to cut into my punch and continue to use
THANKS TED
Thanks for this video. I found an old center punch at a garage sale and now maybe I can make it work again.
That cutaway was awesome! Really helped show exactly how it functions!
As for the soft tip, I tried hardening mine by sharpening, heating to a good bright red, plunge in oil, temper to straw hay color. It seems to have worked, a file won't skate off it but it no longer immediately deforms with the first strike on steel
👍👍
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 !!!
👍
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.
Thanks for the cutaway, that makes the mechanism very clear.
👍👍
Very informative. I retrieved one I had that never worked and found it was not assembled correctly! Thanks for the video.
My automatic center punch stopped working , and I recalled seeing this video quite some time ago. Well, back to the shop to see what happened to mine, now that I know how it works. Thanks! Loved the cut-a-way!
Thanks
At 65, I decided to take a couple of welding courses. Built 2 log splitters and sold them to supplement my social security. May have made $0.20 cents an hour so far but most importantly staying out of the wife's hair. I'm happy that I found your channel. I'm slowly learning the you tube editing process. I too bought a center punch from HF. Doesn't punch after the 4th time of successfully using it out of the packaging. I'll trade it in next time I head there. I enjoy your teachings. So much to learn and so little time. Thanks again Sir!
Thanks for watching. Thats exactly what I earn making these videos!
Love that cut away. The soft points is a design feature to make it easier to sharpen!
Fantastic video. Couldn’t be any better. Thoroughly enjoyed it sir!
Took my machinist apprenticeship back before I went in the navy and as part of the apprenticeship, we had to make our own hand tools, Ballpeen hammer, wiggler, center punch, etc. I used my punch until I found out there was an automatic center punch, which I promptly purchased. It was my favorite 'toy'.
When I got out of the service, I was offered an apprenticeship with a local construction/building firm which I accepted as the money was much better.
I flip-flopped between the two professions for a number of years until finally deciding to stick with the carpentry end. Wood chips were measurably cooler than metal ones.
The point of this tale: the butt hinges you mentioned are integral with any remodel job as many doors are replaced and the blank slabs are much cheaper to purchase. I used butt gauges to score the hinge side for the new hinges and I use a "center" punch for aligning the holes for the hinge mounting screws. I have several "center" drills for the strike plates and peripherals which utilize different size screws as the door size requires.
To summarize, machinists aren't the only people with cool tools. I still rely on my machinist training for a lot of the math and the fit and finish of the final product and there are many times I would recall odd bits to make my job easier.
I definitely enjoy watching all of your videos and look forward to the next offering!
Thanks for sharing...
You are a heck of a teacher Tubalcain, I hope they have a statue of you in the school where you worked.
THANKS--you wish!
Very useful video! Helped me out in troubleshooting my broken punch. Thank you.
I have a cheap chinese auto center punch that did not function every time. With the better understanding through your cutaway specimen I understood what I had to modify: I rounded the hammer face and opened up the catch-pin hole so that it could lean over just a tad to catch reliably. Evberything is working now! Thanks for this informative video!
Thanks for that, gonna try this mod to get a couple of these working right. They used to, i took em apart to see what was inside, put em back together right, havent worked since.
Very interesting video. tried to repair one once and just could not fathom it out. Your superb demonstration made it easy to understand Thank you, much appreciate your time and effort.
I recently got one and was deeply curious how it worked. This answered it clearly.
I'd torn it apart and tried my best to puzzle it together and I thought I was onto something with the "pin" being offset, but wrote it off. Even my wife under the same circumstances made the same note and did exactly what I did. Go with your gut, I suppose.
Thank you!
😀😀
Thank you for your clip. I bought 1 same as in your clip but did not work until i found this clip and used drill to make the hole wider. It works smoothly now.
Tip: if your stuff does not work after full push down, just use metal drill to make the hole little bit larger
Thanks Mr. Pete an excellent job as usual.
Great demonstration as always. Thanks Mr. Pete
Just bought my first center punch today, and this video randomly popped up. Thank you for making this.
Four years old as I watch this for the first time. Very interesting and entertaining as well.
that cutaway makes ALL the difference in the description. fabulous, and thank you!
You're welcome!
Have a HF one that does not discharge. Now I know how to take it apart and find the problem. Thanks mrpete! My other HF one did work though.
There is something rather deep going on here. I’m amazed that someone took the time to show me how these darn center punches worked, because I have several that don’t work properly, and now I will be able to figure them out. But more importantly, I’m amazed how much I need to hear from the voice of experience. In a world where we seem to be in such a rush all the time, it’s good to know that there is some sanity. Thank you from the bottom of my heart. Your wisdom is a balm.
Thank you very much, I’m glad you like my videos
Wow! You explained that SO WELL! I have no questions.
THANK YOU! I have a few of these things and they always go bad.
Now I know that my "repair" job of straightening the spring only made the problem worse.
Now that I know how it works I can fix them!
I know they're a buck or so apiece but i like to fix things
That was excellent Mr. Pete. It's always been a mystery to me. Mystery solved.
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!
Thank you--it seems to farily popular video
Mr Pete, you are the ultimate "You Tube Shop Teacher"! Thank You so much, and "Happy New Year" to you and your family.
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!
Thanks for watching
Mr Pete great video and i love the cutaway and the off center spring.
I like your cut away. Very nice demonstration.
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.
I took one of these apart, rounded the point, and put in a lighter spring. I use it to knock out small dents when restoring aluminum car trim.
Very informational and thorough, Thanks Pete!
Thank you very much for making and showing the cut away. I had wondered for years how these things work and now I know.
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.
The left-handed tread is actually correct for center punches. You can decrease the impact of the hammer by loosing the end cap, thus lengthening the back spring. Having a left handed tread makes this more "natural".
Having a lesser impact with an automatic center punch really worth it if you work on softer metals or some plastics.
Keep up your good work.
Only the cheap HF uses left thread. All others, and the cheap Menards, have regular thread.
Thank you sir. Now, i've understood how it works, i'm able to repair mine.
Thanks for uploading - very interesting!
Thanks
SHOW !
MUITO BEM EXPLICADO!
PARABÉNS!
Most edifying as per usual, and as per usual, thank you for taking the time, for my part your videos are very much appreciated.
Thanks for watching--glad you like
The cutaway punch in the vice was a stroke of genius matey. Explained the mechanics extremely well.
I bought several of those cheapie-type punches - $10 to $15 - in recent years, trying different brands, and was totally unsatisfied. A couple of years ago, I paid $40+ for a Japanese made punch and it is excellent, leaving a really good pop mark, very much worth the $s.
Also, having a punch with very hard point material, we can use it very effectively as a scriber, which is what I do when setting out work.
👍👍
Fantastic Video & Cutaway. Keep up the great work. Nick.
Love the cutaway, i have been trying to repair one of these for a few days now, don't know why as they are very cheap to buy. Just determination I suppose. Your cutaway solved my problem. thank you
👍👍
Thanks Mr. Pete. Very informative.
Thanks from Belgium for this detailed insight
👍
I was this close to throwing out my punch when I saw your video. Turns out my spring needed a bit of a stretch. I did notice the spring was off centered and tried to straighten it out, then promptly put it back. Thanks for the video
I'm glad I helped you
I realize this is an old video in your series, but I really appreciated viewing it. You did a wonderful job of explaining the operation of this little device. The cutout brought back memories of the military as they use that extensively for many things to show the operation. That was genius on your part. I have a couple of these and have used them many times and often wondering how they worked. Thanks for what you do buddy, you are really good. God bless you and yours.
👍👍👍
I use one of these to take out rivets and often wondered how it works. You explained it well.
Excellent explanation and demonstration with the cutaway. It is exactly what I was looking for.
That is NEAT! Thankyou Mr.Peet.
I have a pair of harbour fright punches, one left handed thread, the other right handed. Same product number, bought at the same time. Threw me for a loop... They drove me nuts making cutaways.
that is an interesting little gadget using such a simple way to make it release.
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
