You are not wasting your time. Your videos are very interesting to like minded people. Thanks for your efforts.
Right on Sando.
I for one, am fascinated by demonstrations like this. I remember being warned not to watch from the front the old South Bend shaper working in fear of getting center punched right in the forehead. Once again, you've spent your own time and money to educate us further out here in You Tube land. Thank you, very much.
Greetings Mr Pete. I came accross this old video by chance and you would not beleive how useful I have found it. Since I have lots of bandsaw blade stock (broken blades ) I intend to make an inverted jigsaw mechanism but with a much longer stroke - well you have just provided the solution to my problem. Thank you so much and good health to you and family sir. Ps. I enjoy all of your presentations - including your rants.
Thank you for watching, I’m glad you like my videos
As a retired tool &die maker I enjoy your videos very much especially this one. I ran a shaper in my beginning years a lot.The mill put it out of service. We had a small shaper about 2 foot long. I wish I had it now to play with.I know you were a very good instructor by listening to you.
You are a great man for taking the time to explain things in a way that most anyone
can understand and enjoy. You are so right about trying to figure out what is going on
inside the Shaper. Every aspiring young man or woman should make it a point to
go through your video library. I was a Machinist for 42 working years and I still get a
kick out of watching all of the utube machinists ply their trade. Thank you
Great teachers make it seem so easy it didn't seem to need to be explained. Really enjoyed the Whitworth annotation never even knew it was a man not a place.
Well done Sir! Worth the effort in making your teaching aid. I used a shaper at High School and made a 4 way tool post for my Dad's Myford lathe in 1975.
Recently purchased a milling machine with a lathe to follow.
You are an inspiration Mr Pete!
I love to hear stories where the practical is then explained, also as to who was responsible for said, idea, etc, putting a name to things is great many thanks
I am really interested in metal shapers. Thanks for making a great teaching aid and demonstrating how it works. The great inventors who designed the components that make such things possible are definitely worth spending some time learning about.
Keep it up Mr Pete I watch all your videos The kids you taught in shop were very lucky to have You and so are We..
Mr Pete, you are the gift that keeps on giving. Thank you.
lol
Love the mechanical age...so thanks for breaking down and explaining and passing along these past innovative processes and brilliant inventors.
+sammy mezzacapo THANKS for watching
These types of videos are an outstanding source for provoking thinking. You have a great talent for making things clear. I hope you continue to create this type of instructional material. You have been instrumental in furnishing information for my getting back involved in metal working and machining. Your recommendations to other sites such as Keith Fenner have also been invaluable!!
Thanks Mr Pete!!
Thank you very much
My sentiments exactly!
Grand old teacher Pete. So much gone now and the information and those that knew about these things gone with it. Thanks for what you do.
Please give us many videos on how mechanical equipment works. This was a great video, please continue to expound historically upon the inventors who designed the devices that have made and continue to make our industrialized world. Thanks again for educating us about the industrial awakening of our civilization!
Thanks, I know how much effort that took to do. It is very much appreciated. Very good explanation.
In 1967 at junior college, I used a shaper as part of my machine shop class. I wish I could have seen your video then. Thank you for making it and I think your how it works ideas are great. Thanks also for your historical information in regard to the contributions of Mr. Whitworth.
+Fred Marino Thanks for watching
Tubalcain, You are so full of wisdom. I used to love my wood, craft and metal shop classes in Junior High School but they didn't have those classes in High School. I would have loved to have had you for a teacher. Too old now to get into it at this point but some of your information I can still use while fiddling around in my garage. Thanks for the videos.
+Gary Smythe THANKS for watching
Great video showing how the ratio changed with distance from hub! I love videos on how mechanisms work, all sorts of them. I find mechanical typewriters and old sewing machine internals fascinating, and your videos explain some of what I've seen. Keep making them!
Once a educator always an educator. Another great video. Thanks Mr. Pete.
Dear Mr. Pete, I think your approach to teaching is spot on. The model you made was a tremendous help in understanding how the shaper mechanism operates. Also the history and credit behind this invention was very interesting. Thank you for all your great videos.
I really appreciate all the work you went to. Yes, there are many great men in Europe that invented a lot of intricate and interesting machines. As you mentioned, they do not receive the credit they are due here in the US. I have seen animations on UA-cam of how a Scotch Yoke and Geneva Drive works, to name two. I would be very interested in learning more about these tireless men who invented such devices. Since you have a history of instruction, I cannot think of a better person to accomplish this task. Yes, I would appreciate an insight into these great men and the machines they invented. Thank you in advance.
Dave
THANK YOU.
I, for one, hope you do many more demonstrations like this one. seeing your model made it instantly clear how that mechanism worked. thank you.
Hi Tubalcain.....I have just become aware of your channel and am enjoying your work and enthusiasm for your subjects. I am a woodworker but also like to learn about metalworking too....thank you for taking the time to teach others.
Thanks for watching--and welcome!
The learning aid is very helpful. It allows the imagination of different applications and possible modifications. The historical information about the inventors is interesting. I hope you continue to offer it.
Historical value in your presentation is very appreciated. How it works education is well worth it to me. Thank you!
Your time to make the model of this mechanism was no waste of time and did a great job of illustrating how these old machines worked. Classic designs never go out of style, the older machines had a style of their own that the new machines do not have. Gotta love the classics!
I very much enjoyed your demo of the Whitworth quick return and thank you for taking the time to make it. Made for a understandable explanation.
Another fascinating video I must have watched most all of your 300 + vids and I find them invaluable source of information I have greatly improved on my machining workmanship attending to the finer details does make the "finished look" . I am retired and I enjoy machining my own replacement parts in stainless steel for my 125cc Scooter. You are a superb teacher and explain things well in a way I understand. Keep up the fine work Mr.Tubalcain. and Many Thanks.
Marcus
THANKS
Thank you for a look behind the side plates and into the inner workings of the shaper. It never gets old looking at the mechanical genius of our forerunners. These guys made elegant machinery. It was as complicated as it had to be, not any more than necessary. I wonder what they would think of the constant change on websites that render them harder to use or downright unusable!!!
You are a gifted instructor, and a good egg. Keep putting in your two cents worth, too. I like to know I'm not the only one thinking.
Excellent work! Keep it up!
Im planning on building a modified gingery shaper, after I build the lathe, for a specific project. Plus I like deprecated tech and have an affinity for using old gear to make great stuff for practical use.
So this made me understand the inner workings a lot better. You asked if people want to see more of this. Know that you made an impact on me and my community with your video. We are one step closer to self sufficiency thanks to you and your knowledge.
👍👍👍
Sir, I have always been confused how the shaper generates the different speed. You have in this video, cleared it up for me. Your teaching aid did the trick and it was like a light bulb going off when I saw it work.
Thank you, as always, your teaching is appreciated!
A valuable video and would love to see more. I enjoy the mentioning of great men and how they changed the way we do our work today. :-)
Mr Pete I realize that I am about 4 years late in my comment but yes I do like the how it works and this example has really done an excellent job of seeing how the shaper works. Thanks for all the effort you put into explaining things so people like me have a better understanding. I also admire and respect those pioneer inventors like Mr Whitworth. Keep up the great work of teaching.
Thank you very much for a kind comment
Hi Tubalcain,
I think this is one of your best Videos. The information was inlighting, and for me to here about great inventors is very inspiring.
Thanks Dale d
I've got a very mechanical mindset and love to see how things work and especially the tools and equipment of generations past. I as I was watching this video, my 5 year old daughter sat down and was fascinated with the illustration. Guess she takes after me, not that that's a bad thing.., keep them coming
That there is the best explanation and demonstration of how a shaper works I have ever seen, and although I have tubed a few I never knew Sir Joseph Whitworth came up with the idea and I'm a Brit! I can remember my Dad explaining about threads and his standardisation method long ago when I was but a young lad, 6 or 7 I should think, while we cut threads to replace a rounded nut on some old petrol lawn mower or other in the garage. Happy days. Your short films remind me of them and that warms my heart, so thank you Mr Pete :)
Glad you liked it. There were many great industrial inventions in the UK. The US usually takes credit for all technology.
Now there is a debate to save for another time, perhaps with a roaring log fire, a bottle of fine malt whisky and a blizzard outside :)
When I was looking at the machine actually run, I didn't really notice the difference in the forward to reverse movement, but when you showed it with your demonstrator model, it really made it clear. Thanks, and yes, I would love to see more of your "How it works" videos.... Excellent job.
Thank you for this, I did find it fascinating and a perfect explanation of something I have read about before but never understood. Also nice to hear someone singing the praises of my ancestors achievements. I am from across the pond as well. I have a 1936 Southbend 9" so I am also very aware of the skill and ingenuity of your countrymen as well. Thank you again and I appreciate the effort you went to to do this.
I haven't used a shaper since high school, it's great to finally know how they work. Great stuff and please keep the how it works demonstrations coming. Loved it. Si...
Mr. Pete, I very much enjoyed this type of video. I like stories about inventors and believe there is a lot to be learned and enjoyed by the information.
Mr Pete commented previously that I had an aussie machine - i had never really understood the mechanism and more importantly i am sure I had it running backwards, i.e. fast on the forward stroke - your video has been an invaluable explanation of the process I am deeply grateful.
I've always wondered how the shaper mechanism worked. That's a wonderful teaching aid! Thank you so much for the time and hard work that you put into it. The information about the inventors and the history is fascinating, at least to me.
Thanks
Yes! I think your idea of a ' How does it work' series would be a great help to many of us newbies. Thank you for all of your videos. I have learned alot in the last two years watching.
One word (not Withworth) came to mind is Supercalifragilisticexpialidocious.
Your magician and your explanation are easy to understand. You bring us into the world of invention reproducing the path from an concept to production.
Thanks
Excellent job, Mr. P ! Thanks for taking the time to build and demonstrate. Count one vote here for more "How it Works" vid's !
I really enjoyed seeing your shaper in action and your teaching aid. At first I did not see the return stroke as being faster on the real machine but the difference became very apparent on your teaching aid and your explanation of the more degrees on the return stroke really brought it home. My father had one of these shapers back in the fifties and I loved to watch it work for him. Thanks, sparky.
Excellent demonstration. It`s good to know that Joseph Whitworth is appreciated outside of the UK.
We sure appreciate him!!!
greetings from sweden (:
this type of teaching is very good, it's very easy to understand all the details and to get a intuitive feel for what not to do (such as the gap before the cutting stroke). thank you very much for making this video.
THANKS
Awesome video Mr. Pete! Thank you for going to all the trouble and work to build the models and making the video. The first time you cranked the model and the bull gear made one complete revolution, I understood how the quick return worked. I hope someday find a shaper to add to my home workshop!
You are definitely not wasteing your time----that was first class teaching and communicating....So good to hear references to our old engineering giants....I will watch stuff like this until the cows come home...
THANKS
Your explanation of the various shaper mechanisms was very well appreciated! Thanks, I was smiling the whole time!
I spent a few months on the shaper in my machine shop training in the mid '70's, cutting keyways and splines, making blocks and such things. They were fascinating machines!
My final shaper project was to make a set of dovetails on the shaper with no play side-to-side, no play up-and-down, yet have no bind in movement - without a gib!
I love shapers like I love Linotype machines! Odd, quirky, and about as outdated as a typewriter.
Thanks for watching
Thanks Mr Pete for taking the time Very educational video on a machine that is now much easier to understand
Very nice Mr Pete on your demonstration and history lesson. Your teaching skills are as good as ever. This is a great example of a fixed end lever and a moving fulcrum. Well done.
Regards, greg
Thank you for taking the time to make a mock up of the mechanism, I now can see why the backstroke is faster and understand it whereas just looking at your shaper it was not evident.
Loved the demo of the Quick return mechanism. Showed how it worked perfectly. Personally I would like to see more of this type of stuff.
From the netherlands i would say....never stop teaching us about anything.
Few people have the ability to execute so eloquently a teaching video of this caliber... this is truly impressive! I can see now that your depth of knowledge on subjects is even more profound than I had prior realized. Thank you Sir...
P.S. We like! Thanks for the obvious extra effort that went into this teaching video.
Comments like yours, inspire me to do much more. THANKS!
Thank you Tubalcain for the information. I am convinced that the shaper provides a means of obtaining the best true surface. Keep up the good work.
+Bennett Mills THANKS for watching
have enjoyed all of your videos that ive watched so far. in regards to your "how it works" videos. I would love to see more. you remind me of my old shop teachers, you old timers have a great way of helping us not so mechanically incline individuals understand and explain it in ways we understand.
Dear Tubalcain. I love this video. You did a great job of explaining the mechanical motions and demonstrating the arc length of the cut stroke. I also liked the little history lesson. It made me want to go look up some more about Whitworth! Thank you for the inspiration. I would love to see more of this blend, "How it works" and history.
+Jay Holmes THANKS for watching
Mr. Peterson,
"How It Works" would be a wonderful series! Your explanation was superb on the Whitworth quick return mechanism. I realize that creating such a teaching aid is not a trivial 5 minute affair. Thanks so much for your efforts.
Your display is very good for explaining how the ram moves versus the positions of the driving pin in the bull gear. YES! I like the setup you used. Thank you. Now to get my own shaper working.
Thanks
My father had a shaper, I remember seeing him fabracate items with it when I was young. Thank you for your time and trouble putting that video together.
Sue
These demos are fantastic. What a great teaching aid. More please.
Whitworth was a very clever man, and thank you for the lesson.
Hi Pete,
I enjoy watching your video's. I do not think we give enough credit and praise to the great men of the world that have invented things that we use, or have lead to use's in everyday life. Well done. I think a "How It Works" segment, such as the operation of the Atlas Rhodes Shaper and presented in a similar format, makes very interesting learning and a treat to watch. I personally am amused by your accent, not to sure what part of the US you reside, but very different. In Australia, you just don't get a chance to talk with people who roll there words as you do. Keep up the good work.
Cheers
Pete McCormack
Thank you for simplifying the process. Even though I own an Atlas 7B shaper, it's great to know how the inner mechanics work. Please and yes I would be very interested in a How It Works series. Again thank you for all your efforts and hard work. David
I thought your explanation and demonstration of the Whitworth mechanism was very interesting! Just looking at your model, before you put it in motion, I couldn't convince myself the return stroke would be any faster than the cutting stroke. Thanks for taking the time to make and show the model! Jon
Your mock up is excellent. What an incredible teacher!
This was not a waist of time! Thank you for doing this video I would be interested in others like this. I wish more of my shop teachers were like you when I was in high school!
One of the best teacher ever found in youtube channel. Thank you sir.
Thank you VERY much
Hello Mr. Pete222,I have used very few shapers in my maching days and was not really interested in how they functioned only what they could do, but watching this video and your excellent instructions I am fascinated with the teaching mechanism you used to explain how they work... I believe a lot of todays machining techniques all originated from great men like Mr. whitworth... As for enjoying your how to videos I simply am fascinated... Again, Exvellent video...Thanks,Frank
I know I’m four years late to the party, but this video was fascinating, and I wanted to make sure to thank you for putting together such a thorough demonstration!
Thank you very much
I could not see what was going on until your demonstration. Wish I had teachers like you when I was schooled. "How it works" series would be great.
+Lee Hill THANKS for watching
Thanks for spending the time to teach, It takes a long time to teach a short class.
Yes, sir. Please keep making these types of videos. It took your teaching aid to understand the leverage causing the shaper to speed up on the return stroke. I think it a good idea would be to also see how a 5 axis CNC works. I know that's a tall order.
Not wasting your time, I enjoyed the time, learn something new every time I watch :) THANK YOU.
+ELSDP-45 Thanks for watching
I love this. Thank your for taking the time to teach and teach so well. I understand new principles of geometry/mechanics that I didn't before.
Mr. Tubalcain, This is a great video. I would love to see more "how it's made" videos from you. Watching your video made it easy to see this concept and understand why it was faster on the return stroke. Thank you for your great work and for all your efforts you put into making all of your great videos.
I certainly appreciate all of your hard work and effort into making this "How it works" video. I recently purchased a Atlas 7B and watching your video and playing with the shaper a bit really made it clear how it all comes together. I like to know the science or "magic" behind something instead of someone saying just do it this way or put these numbers in the program etc - no explanation, "just do it like I showed you." If you don't understand how something works to begin with, you may have a harder time trying to correct or troubleshoot something and risk ruining some equipment.
Thank you again!!
Great job on the demonstration aid Mr. Peterson, with the aid I can see the faster reverse stroke because the travel is shorter than at the top of the stroke. Keep up the Great job on all your videos.
What a wonderful teacher you must have been. Such a pity that todays children do not have you experience to learn from at school
Great video. I find it boring when i just have to solve problems of theory of machines. Ur video helped me alot and in a quite broad way to understand the mechanism .. Ur efforts are not wasted.. Thanks alot
Yes, I would love to see, "How it Works". I enjoy seeing you demonstrate something they give your short histories on the object. It's good to see an educated person who can also work with his hands.
A most enlightening video, while I knew that shapers had a non-symmetrical stoke, I did not "perceive" how that happened until your model showed that the pivot point moving to - away from the central axis changed the rate of movement of the end of the lever.. Would love to see more of these .. Thanks Tubalcain
Mr Pete, in my six decades of learning, this class was one of the most enjoyable/interesting that I've attended! The history part, which is very important, along with your visual aid explantion was easy to follow and easy to understand.
I really appreciated your extra efforts building the mock up which provided the 'great show and tell'. Please make some more of these 'how it's made' videos. I'll be a student every time.
Thanks for the lesson....13
For what it's worth: I'd been struggling to work out a mechanism for a project I'm currently working on for the last 3 weeks. A (albeit: heavily-modified) derivation of this design solved my issue. Thank you, sir.
👍👍👍👍👍
Tubalcain, your the best teacher i never had,!!! keep them coming please.............
May we have more videos like this one, please? I am a mechanical engineer, and have studied a myridad of mechanical devices such as this, and have designed machines using many of them. But until one breaks it down into easy to understand models like you have, the HOW and WHY often eludes us. You are a great teacher, as were my high school shop teachers, and have influenced many of your students in ways you probably never knew. Thanks for your continued efforts to teach! Thank goodness for UA-cam, too!
In the late 1970s I took a machine shop course at a South Texas University. The Phd. who taught the course somehow recognized my love of machinery and had me run the tool room and use the antique leather belt wood pully drive metal lathe . I lament that computerized automation is making machinists about as necessary as buggy whip manufacturers. These machines are the mother's of modern computer driven machinery. I truly enjoyed your video and hope you make more as history will need them in order to convey "UNDERSTANDING" of how linkages work . I will use this understanding to patent an invention that needs a reciprocating table to make a food product. There are many ways to reciprocate a table and having this understanding will allow me to broaden my claims in the patent. Thank you Very Much for your clarity of explanation and "Cheers" to you for your fellow love of the inventive spirit.
+Dan V. Thanks for watching, & good luck with that invention
Thank You. The last one # 5590616 didn't do to well but the prototype got a ton of attention!
Oh and one more thing I noticed in your video. Maybe I overlooked it. Did you explain why the return was faster than the out stroke? It has to do with the dynamic leverage advantage that changes throughout the rotation of the drive wheel pin. The pin is essentially a changing fulcrum if you consider the connecting pivot shaft to be a 2nd degree lever. I think.
Yes, please lets see more "how it works".
I am familiar with the Whitworth tools and fasteners, as I work on a lot of old Triumph Motorcycles. I did not know the other contributions he made, thank you for sharing.
Excellent explanation. Well done! And I would certainly like to see more of your demonstrations.
This is a fantastic video. I loved the explanation and having the visual aid made it all the easier to follow. Several times I have paused one of your videos and tried to figure out how/why something works the way it does. For example I had never seen a 3 jaw chuck dissembled before so I had never seen the spiral driving the dogs. I never knew WHY the dogs were numbered. More videos like this? you ask... goodness yes, please!
thank you very much
Thanks for the lesson, I just today bought what i think is a 7" shaper made by the Lock tool company of Melbourne (Australia). It needs some TLC and is missing the clapper box and vice but i got it cheap and all the machined surfaces are very good.
My plan is to restore it and use it, i had to grab it before it found its way to the scrap yard.
I'm 27... some young people like this stuff too.
If anyone is interested here is the thread.

Keep up the good work, it's excellent and the comments on the great inventors is also fascinating.
+Keith Grove THANK you very much!
Nice demonstration of how the old shapers worked...I had only seen pictures of these old relics until now...
Thanks for taking the time to demonstrate this. I appreciate the effort.
I don't know how everyone else voted but a series on "How It Works" would be great. And some history on the inventors is great too. Your video's are a one of a kind here on UA-cam. I watch other machine shop videos but here is where I do my learning. Keep up the fantastic work! It's always a pleasure to watch someone who loves what he's doing and you were made to teach. One of those rare occasions where a fellow chose the career path that was custom tailored for him. I just can't say enough good about your videos.
+Neurotic Nation THANKS for watching
Keep these type of videos coming. I love the history behind them and absolutely love seeing how everything works. It helps me understand how to use something better.
Best quick reverse mechanism demo video on UA-cam ! - Very well detailed and explained - It was very helpful for someone like myself who is building their own small powered shaping machine ! - Thank you and god bless you Tubal Cain - Best Regards from England :-)
Thank you Joe, I don’t think anyone has watched this video in years.
@@mrpete222 You're welcome man.
