No Sir Mr Pete, not lol he is absolutely right. You ARE teaching probably more students every video than pupils you taught in the whole of your teaching career. And I for one are so glad that you are teaching me, and I'm sure every one of your subscribers are just as grateful. Please keep them coming for as long as you are able. Greetings from over the Pond.
Too often my students complain "Why do we need to learn this...". This video shows how knowledge in machine shop, drafting, graphic arts, and even sewing (Fairgate Ruler) all need to co-exist in the same solution to your problem. It was John Dewey that said "Send the WHOLE boy to school", meaning, give him or her a well rounded education. Great series. Never saw a lathe dividing head. Thanks for taking me to school, too.
Your last four sentences are why I watch you,'...even though I could have done this in one tenth the time I like to learn something new...'. I agree 100%, and thank you for the edutainment.
Thank you very much, I had already forgotten that I said that. And I usually do not Expect people to hear things like that. I said for my own entertainment
I just started my classes in Computerized Manufacturing and Machining, and the teacher had one of those old huge teaching aid's in he pulled out on last week.
I don't know the source of it, but it looked exactly like the inch one from your picture. I have been watching abom and a few others often and asked for recommendations for others and he told me about your channel. Been enjoying watching your stuff and what we've done in class
@@wes9731 That one looks to be in better condition (cleaner) than the one my highschool had; Though the picture is making me doubt my memory that school's had decals instead of printed labels under the grease and soot.
A very useful lesson in dividing a circle, from which one can subsequently conquer the world, and then the universe. Definitely a skill worth picking up.
This has been a very interesting series and I want to thank you for all the work making the videos. I love the detail you include and the stories of Peterson products.
Beta was used in television due to it's quality. You could make copies of copies and the quality remained high for a several generations. All our recorded video was on beta. We had a 4 player setup at the tv station that ran commercials. It had gobs of tapes available and a trolley system that would grab the tape, stuff it in the player, then return it to it's place. Back before digital took over. Boxes of tapes would make their way to the news set to be played during the news cast. Woe to the intern that dropped a box. All the taps had to be re-tensioned and re-cued....
Thank you for that, that is very interesting to me. I do remember that when I went to the Chicago auto show a few years back, all of the TV stations were using beta cameras
Thanks for making this series. Yes, it was a long and winding journey, but those are usually the more interesting and worthwhile ones to make. I learned quite a bit on this one!
That is an absolutely fabulous series Mr. Pete. Not useless! I had a fine career I based on using what many called "useless" knowledge. You know, algebra, geometry, etc. Out of 120 at the mill I worked at there were exactly 4 of us who could read a standard micrometer or vernier caliper. Dad taught me at about 9yo. It's folks like you that make a difference. Thank you! 👍
Thank you for that. Yes it amazes me sometimes, how little some people know. But they may know a lot about baseball and all the batting averages of all the players, for the last 50 years, LOL.
This has been interesting process for sure again the information you presented is useful in showing something most of us probably have never seen much less used. Great job
Interesting lesson, my friend. We didn't have teaching aids like this in the school shop. Just large wall-size charts that illustrated using a micrometer. We did have a large slide rule teaching aid (you no doubt remember those) suspended above the blackboard that was used to teach the solution of problems using the various scales on a slide rule. Those were great old days, punctuated only by the anxious realization that the draft board sent notices in the mail on Tuesdays.
I had some big micrometer charts at school, but they were already ancient and falling apart when I started in 1967. I must’ve thrown them away. And yes, the math and science teachers have those big slide rules.
And also, I did get my notice from the draft board to report for a physical. But I do not remember the day of the week, I was too traumatized to recall.
"Left Hand Monkey Wrench" Lol!!! Love it! I still have the micrometer dad taught me how to read when I was in the third grade in school. Teacher and kids had no clue what I had for show and tell and what it was used for. Totally Greek to them. As always, thanks for sharing Mr. Pete, Ken
I consider this series a spectacular success. Thank you, Lyle. If this series was about how to put equally divided marks around a cylinder, the dividing head, along with all the effort to create a suitable plate, would in fact be a horrible waste of time on your part for making all those videos and on ours for watching them. As you said, there are just too many easier ways to accomplish that task. The good news is that was not the purpose at all! The purpose was to show how dividing heads work, using somewhat unique hardware and various problem-solving techniques. The exact end product (lines on a cylinder) of the video series is as useless as the micrometer it created but the techniques the series taught are as useful as the teaching aid they created.
An Apple for the teacher. It was a good series, well-thought-out and I learned something about making the dividing head plates. Thanks for all the effort.
When I started engineering school we ALL had to take Slide Rule class. There was a six foot long slide rule mounted about 5 1/2 feet above the floor in two rings supported by a frame mounted on casters. It was an enlarged version of out slide rules including the markings. The thing was extremely accurate because it was very easy to adjust the slide and traveller.
Mr. Pete, you find the coolest toys! I've worked in the military and industry for over 40 years and never knew such a device existed. Thank you for the education.
What I love about machining is that very simple concepts and operations can create parts or features that your average Joe would have no idea how it was done. Little does average Joe know that it was dead simple....if you know how to do it. Thanks as always Mr Pete!
Thanks Mr. Pete. Many of your videos make me chuckle because they remind me of the high school counselor 55 years ago who told me I didn't need to take an algebra class because I was "just an industrial arts student". I wish I could have shown him when I got a "B" in calculus years later. : )
Some counselors are clueless, because they never took Shop classes. Also, many people look down on shop classes and shop teachers, and even shop students. I experience that many times. That cause me to have poor self image, which I still have
We used to do similar, though on production, way back when, (when? I'm thinking of the sixties), but would use a turning tool on its side to make a groove and fill with red or black wax. Keep up the good work Lyle.
I have said before and I will say it again, I wish I could have been in your shop class. I would have probably gone on to study industrial arts and teach. Thanks for all of your efforts, they are appreciated.
Awesome. I like that little dividing head! I was an early adopter of Powerpoint and making digital photographs to avoid having dozens of 3" binders full of overhead transparencies. As far as digital versus mechanical tools - many years ago I had an apprentice condemn all 4 rotors on a vehicle as under-size. His measurements showed the rotors to be considerably thinner than they actually were; the rotors were replaced a year previous and were basically brand new. The customer - a machinist ironically - came out to look at the rotors and estimated the thickness by eye. When a mechanical vernier caliper was used the estimate was much closer than the measurements taken with the inexpensive digital caliper used by the apprentice. I prefer mechanical tools, no batteries, no sensor deterioration... My eyes don't care so much for them anymore though.
Always enjoy learning, that's why this is my #1 RUclips channel, I learn so much here! Thanks for the great demonstration on the lathe dividing head Mr. Pete! You explained it very well and that teaching aid came out great as too!
This was a lot of fun, and I love that you made a point to wear your safety glasses during the dividing head operation with the Sharpie. (I'm very big on maintaining good habits because safety shortcuts are like potato chips: People never have just one.) Thanks.
Mr Pete a man more interested in teaching students how to grow up with a skill to improve their quality of life for a better citizen for our county so they wouldn’t end up in prison on welfare or on drugs or alcohol for that mr Pete we thank you for a job well done and beyond the call of duty with Peterson’s products no tell how many kids across this great country that would have fell through the cracks just because they couldn’t see what the teacher was showing and learned a skill that made this country one of the greatest country in the world thank you
Us Septuagenarians have to stick together. All your friends, you do not know, came and saw and enjoyed. You keep doing the things you do and we'll keep coming back and looking.
@@mrpete222 My pleasure. I didn't have a shop teacher any where near as good as you are. I wish I had. I probably will never have a dividing head. But if one falls into my lap, I'll know how to use it. Thanx.
My father was in charge of the Calibration Lab for all the test equipment and Microscopes for one of IBM Plants where they made the Wafers and IC for IBM computers in the '60s and '70s. Electronic Test equipment was not handled by his group (O'Scopes, Multimeters Etc). All the masters they had in their LAB were 1 jump away from the NBS masters. Sometimes some of the items were so out of Calibration and could not be fixed (but still usable by a school) he was able to get them donated to the Trade Shop section of our High School - Also sometimes it was marking that were removed from all the use they got. His lab was a Class A cleanroom - Coat with hood, boot covers Mask. It was a AA plate. One year during the summer break he was able to get the plant to Calibration on all the items in the machine shop, Auto Shop, and Electronic Class.
I love learning now. Even though I am 63. Back in high school I probably would have taken machine shop except the teacher was too much to take. So I wound up being a Mechanic instead. Who knows how much differently my life would have turned out?
As always I enjoyed. I also learned a lot. Your so easy to listen to. Keep them coming. I'm thinking you must have been one of the few, with a video camera in the 70's-80's that used it for teaching children. Thanks again.
Yes, and when I look back, I am kind of a maze that I was in to the new technology. I was the only one in the school that had that equipment at that time. And it was bought with my dime. Don’t get me wrong, I am not a trend setter
Mr. Pete, This video is the ninth video if you count the other eight videos on index plate making in your series. You often say "I know I'm beating this subject to death", I and I'm sure all the other viewers love it when you beat a subject to death. I always look forward to seeing your latest videos. Hope to see and talk to you again at this years Bar-Z Bash.
Thanks a lot for this video! As someone trying to learn this stuff on my own, I've seen a lot of videos on dividing in a lathe, and I think this may be my favourite. By making the machining operation be something as simple as making a mark with a marker, you can see the entire flow of the process, but without getting bogged down in the more complicated secondary operations that are usually involved.
Yes, he was often Rude and abusive to me. He was never any help. I recall once that he made our home ec teacher cry. She was a sweetie that everyone on the faculty loved, a great cook, and made cookies for everyone. But he was cruel to her. And she wasn’t bad looking either
A fine finish to a long series. I still have sheets and sheets of Letraset and Ziptone. And a few pieces of Rubylith, in fact. Last major machine restoration I did (20 foot bed, 48" swing lathe, pre-20th century) got letraset labels for the controls and oil points. Clean the paint, rub on, then several coats of clear to protect them. Held up well in service. I still use, and teach, with conventional measuring tools. There is value in understanding the principle in measurement, reliable, robust, and I can get top quality inexpensively on the used market so I can have a sufficient number of calipers and mics on hand. Also can hand them off to students in need when they move on.
Very in formative... I was in the welding shop and we didn't learn about micrometers but I was fortunate to get a job in a machine shop where the owner was an older gentleman took me under his wing and taught me a lot about Machine Tools
That layout triangle was making my eyes water - the perspective was just so wrong, I had no idea what it was and what shape it was - vanishing point was just wrong. So many tools ... Keep up the anecdotes, sir. I really enjoyed hearing about your Betamax machine.
Another great video Mr Pete. I do like to see the manual set ups. I work mostly cnc and miss the manual setting. I enjoy these videos and lets face it, they're better than the stuff on television.
Love me some mrpete222 videos. Every time I watch one, for some reason, I always wish we had a bunch of Mr. Petersons in Congress, or at least as Secretary of Education.
Very nice, Mr. Pete. The tape transport and tape playing mechanism like Betamax was superior. But the best designs don't always win when it comes to retail marketing. Beta style mechanisms survived commercially, that is in broadcast/professional areas long after VHS won the home video player contest. The commercial players used a wider tape and larger cassettes, but the player/recorder mechanism was pretty much the same, just scaled up.
I used Letraset and Mecanorma back in the days when "camera ready" artwork was made by pasting up bits of paper with "Cow Gum". The smell of Cow Gum still instantly takes me back to those times - although they had to change the smell as the solvent they used turned out to be toxic.
Yes, I remember all of that. Paste up as what we called it. Odors, aromas, and smells instantly affect my brain and bring certain thoughts and memories back. The smell of a girls perfume or hair are good examples.
Hi Lyle, From early in your video I was thinking camera and screen and a normal micrometer, we have technology, and I'm also a septuagenarian. The problem with any digital readout is it's not linear but stepped, so the "old fashioned" one will show if you are somewhere in between divisions where the digital will not, and while we might be only talking 0.001" or 0.01mm, that can mean an interference fit or a clearance fit. So learning how to read both forms is important. Also traditional micrometers are still readable with our deteriorating eye sight, where counting divisions on a vernier I find much harder. The dial type is a better option. I think there are more people out there who learn a great deal from you and many other you tube presenters. Regards Dennis.
Thank you very much, you’ll make some good points. Some of the digital micrometers read to four places. Also some of them have engraved lines as well. That may help you determine how far you are in between numbers. Most people are lucky to get within two or 3 thousands anyway But I think we are stuck in the olden days
Another great video! I think I learned to read a micrometer from our industrial arts book but that was over fifty years ago and I can't be sure! I was (am) so interested in shop work that I always read far ahead of the current lesson.
Hi Mr Pete, thanks for showing this divider. You mentioned that the thread was not coarse enough in the model, you probably don’t want any extra work but would drilling and tapping for 3/4 10 tpi and replacing the apparent threaded rod or bolt with matching thread work?
Its a very nice teching movie how to make a precision measuring instrument using artistic tools, mechanic aid (dividing head) big machine (lathe), little fractional math. Thanks very much!
Regarding the need to know how to read old school verniers and measuring tools. I like the digital readouts, they make reading the mic's easy. However, are you going to quit work and go home when the battery runs down and you don't have a spare battery. I think even though we like to use the new tools because they are easy to use, we still need to know how to use the old reliable mic's with engraved markings and sometimes with verniers. You are not wasting any body's time teaching people how to read old school tools. Just a suggestion, maybe a video on reading vernier scales! Love the vids, keep them coming.
I agree totally with you. And I just hate batteries. You may have noticed that recently I purchased a starrett vernier caliper. My original intentions were to make a video as you mentioned. But I have been making too many videos that I think would be neat for the viewers, but there were no viewers.
Wow! A a collector of micrometers I would love to get my hands on one of those old teaching aids. Do you know if any of them are still floating around out there? Do they ever pop up on eBay? Great work!
A few people around the country have told me that they have seen them in classrooms. So there must still be if you were around. But I have none myself. And by the way, I love your videos
@@mrpete222 that's cool, so maybe there is a chance one will turn up! Just hope they don't go the way of much old teaching material, into a dumpster! And thank you, that means a lot! Between you, Tom Lipton and Abom69 I wouldn't know anything near what I do now about machining. These videos are a treasure!
As students we never realised the lengths that some of our now (in most cases) fondly-remembered teachers went to deliver the curriculum - thank you for your recollections from the coal face, the insights from the other side of the teacher's desk are always interesting to my adult self :). I was at primary school in the late 1970's as the AV revolution was starting to take off down under -I feel that some teachers used AV to augment the content delivery, and a few just used it to fit in a snooze :) (it takes all kinds, I reckon). There was lots of educational government-broadcaster-sourced content.down under, the teacher would wheel out a 20" TV on a tall trolley and play a video cassette or a real-time broadcast - still a bit hard to see from the back of the room at times :)
I was going to do that, but it would have been too narrow. And by then I realize why I go to the effort and no one will watch this anyway. And of course that was a self-fulfilling prophecy, LOL.
I love your teaching style! As an engineering student my wheels are always turning. I have noticed most of the older lathes have the head-stock mounted on top of the ways. I also hear they always have wear in the same area on the ways and lead screws. That makes sense because most work is done close to the head. Did any of the old engineers not think to make the bed symmetrical so you could turn it around and mount the head and tail components on the opposite sides? Like flipping your mattress. This would allow extended life of the ways. I was looking at a Southbend lathe from pictures and the base of the bed ends are of different sizes with the head being larger to allow the belts to be fed from underneath. If you fed the belts from the rear do you know if a bed flip is possible?
I do not think that would work. But everything you said makes a lot of sense. But of course they didn’t want them to last forever. The sooner they were out the better. Will sell them another one. And then another one. Ad infinitum.
I've got to say I have thoroughly enjoyed watching this epic miniseries. You are if nothing else a very determined person...and also you are your own worst critic. BTW I do know people who also bought into the Beta format. I didn't but do know people who did.Lol!
Canuck Loyalist I had s Betamax back in the early 80’s, used it for years before VHS came out. There was only one store in Pittsburgh that rented beta tape movies back then and it was a 40 minute drive round trip. But don’t knock the format. TV stations used beta machines to archive footage, still may for all I know. It’s the best non digital format
Lyle thx for sharing. I wasn't aware that a dividing head was available for a lathe spindle. That was so cool. I'm going to work on an adapter for my 6" dividing table for my lathe spindle. Keep up the great lessons. You know many micrometers are still around that are not digital. So, knowing how to read a manual micrometer is still important. I wonder if a clear coat of paint would protect the markings that you put on that teaching aid? Hopefully it wouldn't dissolve the ink and leave you with a smeary mess. Thx again for sharing, indexing, that is.
How about a video on how to use a micrometer? I bought dial calipers before learning the micrometer. Keep the videos coming. Can’t get enough knowledge
What do you mean you're not teaching anymore? You're teaching millions now and I"m glad you're doing it.
lol
So am I even though I do know alot of this stuff he has so much information I wish my teschers would have went into
Exactly, he's teaching every day, 24 hours a day, without even leaving his workshop, and doing it extremely well too.

Sometimes some of the items were so out of Calibration and could not be fixed (but still usable by a school) he was able to get them donated to the Trade Shop section of our High School - Also sometimes it was marking that were removed from all the use they got. His lab was a Class A cleanroom - Coat with hood, boot covers Mask. It was a AA plate. One year during the summer break he was able to get the plant to Calibration on all the items in the machine shop, Auto Shop, and Electronic Class.
Thank you, very interesting
I love learning now. Even though I am 63. Back in high school I probably would have taken machine shop except the teacher was too much to take. So I wound up being a Mechanic instead. Who knows how much differently my life would have turned out?
As always I enjoyed. I also learned a lot. Your so easy to listen to. Keep them coming.
I'm thinking you must have been one of the few, with a video camera in the 70's-80's
that used it for teaching children. Thanks again.
Yes, and when I look back, I am kind of a maze that I was in to the new technology. I was the only one in the school that had that equipment at that time. And it was bought with my dime. Don’t get me wrong, I am not a trend setter
Mr Pete today’s video is fantastic I learned so much you are still a great teacher I learned so much from this group of videos I enjoy them so much
Oh man!!! That is entertainment and educational 👏🏻👏🏻👏🏻
👍
Thanks for Sunday School!
lol
Mr. Pete, This video is the ninth video if you count the other eight videos on index plate making in your series. You often say "I know I'm beating this subject to death", I and I'm sure all the other viewers love it when you beat a subject to death. I always look forward to seeing your latest videos. Hope to see and talk to you again at this years Bar-Z Bash.
👍👍
Mr Pete you are the BEST thank you
Out of good better and best, I hope I am at least good!
G'day Tubalcain. Dividing on the lathe is a stimulating topic. Thanks!
👍
Thanks a lot for this video! As someone trying to learn this stuff on my own, I've seen a lot of videos on dividing in a lathe, and I think this may be my favourite. By making the machining operation be something as simple as making a mark with a marker, you can see the entire flow of the process, but without getting bogged down in the more complicated secondary operations that are usually involved.
Thank you, I’m glad you liked it
This was awesome Mr. Pete! I never knew they made a dividing head like that for a lathe.
Nice work pete !!!
A lot of great info. Now to blow snow
Ehhh.. ohhh snow snow. Thought we watched RUclips the same way....
AV Director=non faculty=above scale=arrogant=bully. Love your videos Mr Pete.
Yes, he was often Rude and abusive to me. He was never any help. I recall once that he made our home ec teacher cry. She was a sweetie that everyone on the faculty loved, a great cook, and made cookies for everyone. But he was cruel to her. And she wasn’t bad looking either
A fine finish to a long series. I still have sheets and sheets of Letraset and Ziptone. And a few pieces of Rubylith, in fact. Last major machine restoration I did (20 foot bed, 48" swing lathe, pre-20th century) got letraset labels for the controls and oil points. Clean the paint, rub on, then several coats of clear to protect them. Held up well in service. I still use, and teach, with conventional measuring tools. There is value in understanding the principle in measurement, reliable, robust, and I can get top quality inexpensively on the used market so I can have a sufficient number of calipers and mics on hand. Also can hand them off to students in need when they move on.
👍👍👍
An absolutely delightful video. I enjoyed your comments regarding your successful past and how life really was. Your a pretty good guy.
Thanks
Very in formative...
I was in the welding shop and we didn't learn about micrometers but I was fortunate to get a job in a machine shop where the owner was an older gentleman took me under his wing and taught me a lot about Machine Tools
👌
That layout triangle was making my eyes water - the perspective was just so wrong, I had no idea what it was and what shape it was - vanishing point was just wrong. So many tools ...
Keep up the anecdotes, sir. I really enjoyed hearing about your Betamax machine.
lol
Another great video Mr Pete. I do like to see the manual set ups. I work mostly cnc and miss the manual setting.
I enjoy these videos and lets face it, they're better than the stuff on television.
Thanks
Awesome video from a Manufacturing instructor in Maryland!
Thanks
Thanks mr Pete
👍
Nice teaching aide. It's way better than crooked photocopied micrometer readings with all the lines blurred together.
Excellent tutorial - thanks!
Thanks
Your still teaching mrpete222 😉 thanks for another educational video.
👍
Mr. Pete maybe you could use some type of spray lacquer to protect the lines?
I was thinking that
I was thinking of something similar. I think I sense another learning experience coming on.
trialnterror Forby’s Tung oil spray finish will work very well on metal
Thanks Lyle, I had no clue how to do that before! Thanks again!
👍👍
Love me some mrpete222 videos. Every time I watch one, for some reason, I always wish we had a bunch of Mr. Petersons in Congress, or at least as Secretary of Education.
Thanks. I would like to straighten them out in Washington.
Man, your magic marker script is perfect! I'm impressed how nicely done that is. A . . . Ok A-,A+ when completed. You have one day.
Acid resist then dip bevel in acid. Then enamel marks.
Thanks
Very nice, Mr. Pete.
The tape transport and tape playing mechanism like Betamax was superior. But the best designs don't always win when it comes to retail marketing. Beta style mechanisms survived commercially, that is in broadcast/professional areas long after VHS won the home video player contest. The commercial players used a wider tape and larger cassettes, but the player/recorder mechanism was pretty much the same, just scaled up.
I used Letraset and Mecanorma back in the days when "camera ready" artwork was made by pasting up bits of paper with "Cow Gum". The smell of Cow Gum still instantly takes me back to those times - although they had to change the smell as the solvent they used turned out to be toxic.
Yes, I remember all of that. Paste up as what we called it. Odors, aromas, and smells instantly affect my brain and bring certain thoughts and memories back. The smell of a girls perfume or hair are good examples.
Once again, Amazing video to watch with my coffee. I goofed in school, and took woodshop, then football. Today I use machine tools!
Thanks
Hi Lyle,
From early in your video I was thinking camera and screen and a normal micrometer, we have technology, and I'm also a septuagenarian.
The problem with any digital readout is it's not linear but stepped, so the "old fashioned" one will show if you are somewhere in between divisions where the digital will not, and while we might be only talking 0.001" or 0.01mm, that can mean an interference fit or a clearance fit. So learning how to read both forms is important. Also traditional micrometers are still readable with our deteriorating eye sight, where counting divisions on a vernier I find much harder. The dial type is a better option.
I think there are more people out there who learn a great deal from you and many other you tube presenters.
Regards Dennis.
Thank you very much, you’ll make some good points. Some of the digital micrometers read to four places. Also some of them have engraved lines as well. That may help you determine how far you are in between numbers. Most people are lucky to get within two or 3 thousands anyway But I think we are stuck in the olden days
Another great video! I think I learned to read a micrometer from our industrial arts book but that was over fifty years ago and I can't be sure! I was (am) so interested in shop work that I always read far ahead of the current lesson.
You were an exceptional student then. I could not get the kids to crack the book
I had never heard of decalcomania. Thanks for the trivia!
👍
from one septuagenarian to another well done
lol
I enjoy learning something new..It is good exercise for the brain.. especially as we get old
Yes
Hi Mr Pete, thanks for showing this divider. You mentioned that the thread was not coarse enough in the model, you probably don’t want any extra work but would drilling and tapping for 3/4 10 tpi and replacing the apparent threaded rod or bolt with matching thread work?
Its a very nice teching movie how to make a precision measuring instrument using artistic tools, mechanic aid (dividing head) big machine (lathe), little fractional math.
Thanks very much!
Thanks
Looks good, Mr. Pete. Thanks for the video.
Thanks
Regarding the need to know how to read old school verniers and measuring tools. I like the digital readouts, they make reading the mic's easy. However, are you going to quit work and go home when the battery runs down and you don't have a spare battery. I think even though we like to use the new tools because they are easy to use, we still need to know how to use the old reliable mic's with engraved markings and sometimes with verniers. You are not wasting any body's time teaching people how to read old school tools. Just a suggestion, maybe a video on reading vernier scales! Love the vids, keep them coming.
I agree totally with you. And I just hate batteries. You may have noticed that recently I purchased a starrett vernier caliper. My original intentions were to make a video as you mentioned. But I have been making too many videos that I think would be neat for the viewers, but there were no viewers.
I would have loved to have had you as my machine shop teacher!!
👍👍👍
Thanks Mr. Pete, i had a good hard chuckle with the " well there is no purpose of this video" I'm glad I had just swallowed my coffee...lol
lol
Wow! A a collector of micrometers I would love to get my hands on one of those old teaching aids. Do you know if any of them are still floating around out there? Do they ever pop up on eBay? Great work!
A few people around the country have told me that they have seen them in classrooms. So there must still be if you were around. But I have none myself. And by the way, I love your videos
@@mrpete222 that's cool, so maybe there is a chance one will turn up! Just hope they don't go the way of much old teaching material, into a dumpster!
And thank you, that means a lot! Between you, Tom Lipton and Abom69 I wouldn't know anything near what I do now about machining. These videos are a treasure!
That was a SUPER interesting demonstration with the dividing head, amazing! Thank you Mr. Pete! Dave in RI
Thanks
As students we never realised the lengths that some of our now (in most cases) fondly-remembered teachers went to deliver the curriculum - thank you for your recollections from the coal face, the insights from the other side of the teacher's desk are always interesting to my adult self :). I was at primary school in the late 1970's as the AV revolution was starting to take off down under -I feel that some teachers used AV to augment the content delivery, and a few just used it to fit in a snooze :) (it takes all kinds, I reckon). There was lots of educational government-broadcaster-sourced content.down under, the teacher would wheel out a 20" TV on a tall trolley and play a video cassette or a real-time broadcast - still a bit hard to see from the back of the room at times :)
Thanks
23:17 I use to use a product called Press Type which is probably the same as Zipatone.
Transfer Type was the name we used to describe those rub on letters.
Veery. Cool. Thank you for posting.
👍👍
mrpete222 👍👍👍
Nice video! That looks like a fun project. I'm a bit surprised you didn't use a 60° lathe tool as a graver to get nice engraving.
I was going to do that, but it would have been too narrow. And by then I realize why I go to the effort and no one will watch this anyway. And of course that was a self-fulfilling prophecy, LOL.
I love your teaching style! As an engineering student my wheels are always turning. I have noticed most of the older lathes have the head-stock mounted on top of the ways. I also hear they always have wear in the same area on the ways and lead screws. That makes sense because most work is done close to the head. Did any of the old engineers not think to make the bed symmetrical so you could turn it around and mount the head and tail components on the opposite sides? Like flipping your mattress. This would allow extended life of the ways. I was looking at a Southbend lathe from pictures and the base of the bed ends are of different sizes with the head being larger to allow the belts to be fed from underneath. If you fed the belts from the rear do you know if a bed flip is possible?
I do not think that would work. But everything you said makes a lot of sense. But of course they didn’t want them to last forever. The sooner they were out the better. Will sell them another one. And then another one. Ad infinitum.
I sooooo wish I could go back in time and have had the ability to be one of your students!
👍👍
I've got to say I have thoroughly enjoyed watching this epic miniseries. You are if nothing else a very determined person...and also you are your own worst critic. BTW I do know people who also bought into the Beta format. I didn't but do know people who did.Lol!
👍
Canuck Loyalist I had s Betamax back in the early 80’s, used it for years before VHS came out. There was only one store in Pittsburgh that rented beta tape movies back then and it was a 40 minute drive round trip. But don’t knock the format. TV stations used beta machines to archive footage, still may for all I know. It’s the best non digital format
Nice job.
Lyle thx for sharing. I wasn't aware that a dividing head was available for a lathe spindle. That was so cool. I'm going to work on an adapter for my 6" dividing table for my lathe spindle. Keep up the great lessons. You know many micrometers are still around that are not digital. So, knowing how to read a manual micrometer is still important.
I wonder if a clear coat of paint would protect the markings that you put on that teaching aid? Hopefully it wouldn't dissolve the ink and leave you with a smeary mess.
Thx again for sharing, indexing, that is.
I have never heard of a lathe Index head until I bought this one a few months ago. I did not know what it was when I bought it
Professor, I like it.
Thanks
How about a video on how to use a micrometer? I bought dial calipers before learning the micrometer. Keep the videos coming. Can’t get enough knowledge
They’re already is one
