I'm so glad you're keeping the series going. Thank you Mr Pete.
These mystery tool videos are some of my favorites! I know you've mentioned before that they don't perform as well but I'm sure glad you keep doing them.
I enjoy every episode you make, Mr Peate. You find the coolest items to spread knowledge to people. I might say more than anyone else on the internet today. Stay healthy and safe, and please keep spending time with us.
😀😀😀😀😀
I will never get tired of these videos
Thanks
My father worked for Standard Container Company out of Montclair New Jersey. They made the old traditional red and yellow StanCan gasoline can, ammo boxes C-Ration cans, Folger's coffee cans. He was an industrial engineer and worked for Standard for 50 years. In all of my days of tooling around with him at the plant, I never once saw him use a can seam micrometer, and never saw one floating around the plant.
I remember those Stancans
@@mrpete222 Me too, I had all the free ones I wanted...the metal spouts always leaked though.
Thank you Mr Pete! It was a thrill to see my comment made the video! Forever great full for your tenacity in teaching all of us with your videos! Craig-
Glad you enjoyed it!
Outstanding job on the Harmonic Drive! I knew you would like it. They used this harmonic in 3 places on Harris web offset presses. 1) at the infeed, the infeed is a drive roller with a rubber roller against it that pulls the paper from the roll and hold tension going into the printing units. The cup of the harmonic was attached to the end of the roller and a small drive motor drove the inner race (the egg shaped one) to speed up of slow the roller. 2) The chill rollers basically the same set up. They controlled tension and also cooled the paper after the dryers. And 3) for the plate cylinder drive where a stepper motor mover the cylinder as needed to control the register.
Thanks for sharing those applications.
People seem to be intrigued by this device
Very interesting group of items. Keep up the series...
I sure do enjoy this whole series.. It is fun to learn about all the gadgets. So rarely see a harmonic drive reducer.. they are amazing. .. Frank was indeed a great entertainer.. absolutely. All my ancestors are from Sweden and Norway too... yah shoore, yew bech yah👍
lol
Good morning Lyle,
Very educational lesson regarding the harmonic drive.
A big thank you to Mark for sending this to you.
I watch both of your channels and enjoy the usable content, short and sweet.
Have a great day gentlemen.
Thanks for watching!
Wow, I had no idea about these. So cool, keep us learning. 😊
Thank you for posting this video. You hit a home run with this one as far as I am concerned.
Glad you liked it.
Amazing sir.
From Florida.
Learn Alot here on your channel.
Thank you
once again, a master class . thank you Dr. Peterson !
Hi Lyle,
Those drives are also being used in telescope mounts for their no backlash and high load capability. They allow for long exposures with a minimum amount of error correction. They make it easier to track an astronomical object to identify asteroids and comets for amateur astronomers. I enjoy watching all these What Is It videos. You and your family stay safe.
I'm glad you're enjoying the series!
Everywhere is a classroom with the right teacher! That's you Mr. Pete!
👍😀
Mr. Pete, Lyle, Mr. Lyle Peterson. You must be the best shop teacher that I ever could have hoped for. You don't know how much I enjoy learning things coming from your mouth, the mouth of so much experience. My dad was a machinist for over 40 years. I was lucky enough to get a job working along side him and my younger brother. In my opinion there's nothing better than working with family that shares the same interest.
I am honored to be considered a teacher!
That was so nice of Hank Hill to help make this possible.
Funny!
This is a great feature of your channel thanks for the video. Keep on keeping on.
Hello Harold
That harmonic drive is very interesting. I've never seen one before. Learned something new today!
Thanks, Mr Pete. Keep them coming.
To me, #3 is probably the most interesting item you have ever shown. I have heard many times the term harmonic gear reduction, but had never seen one or had a clue how one worked. Thanks.
Thank you for watching!
😊
Awesome video! I never knew how these worked, thanks!
That was really cool bud. love these
Thank you Mr. Pete for your work. Hello Mrs. Pete, good day to you both.
These drives are indeed used on industrial robots for their compact design, strength and accuracy. We used Kawasaki robots where I worked years back and the drives are VERY costly to replace if a robot is crashed or overloaded. Very reliable, though, if not abused.
Mr. Pete, greetings from the oldest town in Texas, Nacogdoches. Another great video.
Now I know what a harmonic drive is, fascinating!
Even more impressive is that they can make those small adjustment on a printing press while it's running. Really interesting stuff.
It sure is!
Thanks MrPete.
Have a great day.
Thank You Lyle Peterson.... TM
I'm still alive! I've just returned from the eastern Caribbean. I'm looking forward to watching the videos I've missed.
Thanks, Mr. Pete!
Welcome back!
HA HA HA, YOU GOT ME LYLE. I didn’t think anything about that bbq lid device being from Hank Hill until you said it was a propane accessory. Good one. You are Hill-larious again.
Lol
I hardly ever see a "mystery tool" on any other channel that I can't identify.
Not so Mr. Pete's mystery tools. Which is why I'm here, of course.
👍👍
Mr Pete, i am a Norwegian farm worker( worked with farming for about 40 years) , and i have machining,welding, repairing old engines and gearboxes, hunting and sea fishing as my hobbies
Thank you, I find that interesting.
Mr Pete, you are a treasure!
😀
Once you said what it was, I thought the can seam measuring tool would be to measure the outside height of the seam rather than its thickness, by holding it, thimble up, against the rim of the can. A pity the Starrett catalogue didn't show it in use.
The pin you showed in the catalogue photo would be able to measure the inside seam height.
Wow that harmonic drive is very interesting I have never heard of one, thanks Mrpete I have learnt about something new 😁👍👍👍👍👍
Nice items. I have never see a drive like that, very interesting. Thanks for sharing.
Glad you liked it!
I missed the last one where these were shown. I know. I'm a baaaaaaaaaaaaaaaaaaaaaad boy!
I don't do barbeque so I don't even own a grill. Therefore, I have never seen such a gadget.
The Campbell Soup mics were neat! I never even suspected that such a thing would be required. Also, your brother was correct. Progresso has a superior product by far.
So THAT is what a Strain-wave/harmonic drive looks like! They are now the rage in telescope mounts but, I've never even seen one. Far out man! I like Winky's Work Shop. Great guy. Very smart. Almost as smart and Mr. Pete.
lol
Love these videos mr. Pete. Thank you
Very informative "What is it". Thanks Mr. Pete.
I can see a harmonic drive on one of your band saws also can see that you are quite excited thanks for the post🤗😎🤗😎
That wave generator is AMAZING!! Thanks for sharing! Its the first I've seen of them.
I now can say I have completely disassembled and reassembled ever nut bolt and screw with the exception maybe 3 screws on the very top downed worm drive gear assembly of a Bridgeport J head series 1. Every bearing too, except the one needle pin bearing. I haven't powered it up yet though. (Adding 220 for it in the garage)
>>YOU could make a LONG LONG video content of reconditioning a Bridgeport from bottom to top with all those parts in those machines! (getting to be an expensive winter project) (:
👍👍😀😀
Another great video, and learnt something new, I was never aware of that type of gear
Mr. Pete,
This is your best mystery tool video. I didn't identify any of the items, and I purposely didn't cheat and read the comments. I waited for your answers.
I find no pleasure in grilling, and my wife's Blackstone grills have no lids.
My son-in-law is a production engineer in a General Mills plant. I am awaiting his confirmation that he uses the micrometer.
I know about harmonic or wave gear reduction units. I have frequently described their function, but I have never disassembled one. Another feature that you didn't describe is the compactness of the design, as opposed to double gear reduction, which is far more common. I only ever serviced one unit in my entire career, and it was integrally assembled as a motor/gearbox assembly. The motor failed, and production demands required immediate replacement, so I ordered an OEM unit. I brought the assembly home, intending to disassemble it as a homeschooling project with my boys. We never took it apart. The unit was a chip conveyor drive on a CNC gear hob using a magnetic conveyor. The entire gearbox was roughly the motor diameter and probably only 2.5" thick. It looked like a fat endbell C face motor. This application required no antibacklash feature. It was all about space requirement reduction. The size of your unit misled me. I can see why industrial robots employ the design. My understanding and my description of this design and function has been limited to brief "textbook" description. Thank you for the dissassembly and demonstration. I have already forwarded your video to my boys as a post homeschooling graduate lesson. Some of them have graduated their homeschooled sons, who are in their 20's. It is never too late to learn something new.
👍👍👍
Keep WHAT IS IT? alive it is a great series,
Great video Mr pete that drive was very interesting !!!
I always questioned how they worked, thank you! You will always be my teacher.
Another great video, thanks
Glad you enjoyed it
that was hilarious thanks mr Pete
😀😀
Thank you Mr. Pete, good video!
Very interesting and I learned something new. Thanks for giving me another rabbit hole to go down.
Thanks for the video Mr. Pete. I find all of your video interesting.
Fascinating video!!! Thanks for the education.
Thanks Mr Pete. That was fascinating.
First time I can’t recollect seeing a harming drive. That is a truly ingenious device. Thanks for sharing.
Super interesting!! Thanks Mr.Pete!
Mr. Pete you are a Pisser the Hank Hill comments got me laughing thank you for the video
Mr. Pete is still the teacher, as I learned something new today!
Thank you very much
Fascinating!
I thought that first one was a portable truck rifle rack! LOL...
Yes, but you would need two of them
Those are obviously splines!
10 seconds later: 🤯
Those are obviously gears!
That is some interesting stuff about that harmonic drive. I have been in the car plants and watched those robots working and was very curious at how they worked with that accuracy now I know.
That harmonic drive is cool.
I enjoyed this when it came out 2 days ago and was interested to see that another RUclipsr I follow, Kevin Loughin The Old Tech Guy, put out a vid today about using a 3D printed version he designed of the Harmonic Drive for a project he is working on.
Thanks for sharing interesting vids.
Thanks, I will look that video up and watch it
One of your better ones
Hey Mr Pete we enjoyed that one really neat
Wao. Number 1 really impresed me. I'll bet it took some really advanced AI to come up with a better way to hold up a lid. Added to shoping list
Lol
Thanks mr pete, i learned something today 👍👍
Fascinating Mr P.
Great job guys. Thank you 😊
One of the machines I babysit at work has a tiny harmonic drive box, less than 2” cube. I always wondered how exactly it looked inside. Thanks
Didn’t know they made them that small
Great quizzes! Thanks 😊
Hey Mr Pete, enjoyed the “education” as always. I prefer the descriptions along with “answer” portion in the same video. The selections you depict are almost always unknown to me, and I admire reading the narratives by your viewers !!
John
Thank you.
First time I seen a Harmonic Drive was on a Hitachi robot. I thought I had seen every type of gear reduction their is, was so excited I had to get my Dad to come see it as well. Another thing these drives are nice for is that it makes servicing the electric motors real easy, you just pull them out kind of like you do with a Lovejoy type coupler.
Good morning, Mr. Pete. Most interesting on that harmonic drive. I worked for a CharBroil subsidiary in Texas in the early 2000's. One by one, they took our product line to China. Shortly thereafter the entire CharBroil product line built in Columbus Georgia went to China. Put a lot of Americans out of work.
I am sorry to hear that
I bought that grill about 10 years ago when our local Kmart was closing out.
Always Great Lyle ❤❤❤❤
I worked in a factory where I operated a slitting machine for cutting cigarette filter paper. We had a huge web printing press there, and no doubt it had one of them in it, but I never would have known it. I would imagine they are made specifically for a desired ratio, and aren't variable. I wonder if just changing the profile of the eccentric is how the ratio can be changed?
As always mr pete very interesting video
Thanks Lyle, have a good week.
Very cool!
Thanks again, Mr. Pete.
Hi Lyle, i am from the more swedish west side of Finland, not so far from 50 years old nowdays. Interesting that you have relatives here in scandinavia..
I am just love mechanics and electronics and also doing those kind of things for living. Longtime subscriber of your channel, Thanks for your videos.
👍👍😀😀
great video,
have a great day
Greetings from Finland!
Hello
I have never even heard of such a thing before! Very interesting for sure. As a builder of brick dog houses ( you know what I mean?) if someone showed me that I'd swear it wouldn't work or last more than an hour before wearing out. It's an amazing design
The #1 grill prop, I saw people use something like that to store Christmas lights. They would wrap the lights around it.
awesome ----- love the harmonic drive ------ never knew they existed ! ----- what sort of mind came up with that ???
Great video and that Gear reduction unit is really cool !
That was a most interesting item. I have herd of harmonic drive units but had no clue how they worked.
That reduction gear is amazing. First exposure to these.
We always called that smell a "Campbell's soup fart". The vegetable beef one is the worst. Of course we all tried to top it after dinner.
😂
cool stuff
Thank you Mr Pete
I can’t believe you have watched King of the Hill
I have heard of a harmonic drive but never actually seen one. Thanks for posting
my near complete ignorance has been improved, thanks Mr Pete!
I'm wondering if the grill lid prop harkens back to the old charcoal grills?
Not if it belonged to Hank Hill
My granddad was from Holland. I think I got my calm demeanor from him. 😊
