WHAT IS IT? Mystery ITEMS  

Yep I was correct, I didn't know any of them. 100% for me.

the veil of ignorance has been lifted , thanks Mr Pete. also the time of release is perfect for Western Australia , 5pm.

I remember the Whitney's catalog sold tire groovers for retreads

My father was an upholsterer and I was the staple remover when he did a side job at home. I wish that he gave me one of those to dig out some of those stubborn staples. He like most other upholsterers in the 1970's used a pneumatic staple gun that could burry extra long staples coated with some kind of glue into a piece of Oak as fast as he could pull the trigger. Those staples were extra hard to remove but I got them out every time. On the nicer furniture he would put a hand-full of sterilized upholstery tacks into his mouth and used a little magnetic hammer to "Spit tacks" which were much easier to remove and were supposedly safe to swallow a few my mistake.

Yessssss. 91B. Thank you for posting.

Excellent answers. The only time that I used a burnishing tool was on through hole oillite bushings as illustrated in clip. We pressed off the shelf oillite bushings into bored holes in plate material for plain bearing application. The press fit reduced the ID slightly. The burnishing tool restored the assembled bearing to specified dimension. As the maintenance technician, I simply observed this task and never bothered to really examine the tool. I only occasionally did some fill in production work. I don't believe that our burnishing tools had the moveable wedge feature, which I assume has some designed or adjustable stop to ensure size and repeatability in your versions. Our bushings were pressed into large plate parts and were seated by hand driving with a custom drive punch and fixture that sort of controlled seating depth and perpendicularity (another cause for bushing distortion). Some operators ran the burnishing tool dry, most added a squirt of oil. Some have confirmed that your examples are bottoming burnishing tools. The hole bottom may set the wedge position??? Large burnishing operations were driven by a heavy radial drill. I didn't fully grasp how the watch maker lathe operated, even with your description. I was completely clueless about the tire grooving tool, in spite of part A comments. Showing us the power cord attachment plug helps me understand how it was used successfully. I have never had any personal need to regroove a tire nor have I seen the operation performed. Thinking about tire maintenance causes me to recall a short lived tire balancing machine employed at our local SEARS store tire shop in the late 1970's. The balancing machine shaved off tire rubber as the tire spun on the balancing machine, sort of a lathe operation. I only observed this operation from the vantage point of the public parking lot. I don't know how the operation was controlled, but the operation resulted in enormous piles of tire rubber shavings. Maybe lead weights are too costly for SEARS, maybe it shortened tire life expectancy and increased replacement tire purchases???

I didn’t catch the a. Series but the burnishing tool picture got me

I got the tire re-groover right. Used one when I was young. 60 years ago.

i guessed roller burnishing tool from the thumbnail even though i actually never saw one . now i have. great

This series always amazes me as there were once tools to do any and every process. Now, not even the processes exist. Repairs for example. Nothing is repaired anymore, just discarded and replaced. The burner on my Mr. Java coffee maker went kaput. After searching high and low, I found a replacement burner. About the same price as a new Mr. Java coffee maker.

I always learn something from your videos. Thanks for sharing

Thanks again Mr. Pete! :)

That tool is intended to re-groove tires. Certain tires were actually branded re-grooable on the side wall. A Sipe tool has a blade like a razor or thin knife.

Figuring out what the mystery items are is getting harder all the tiime. Thanks for the video keep on keeping on.

That was fun! I can just picture someone getting ready for a race and making tires for the new race track. FUN!

Great job. Thank you 😊

I used to get my tires siped every winter when i didn't have enough money to buy decent snow and ice tires. you just can't beat modern snow tires though

Very good. Mrpete

These are still some of my favorite videos. I feel accomplished if I know even one of them some days. Even if I'll never use it, I find it fascinating how tools are designed and how they accomplish a specific task. It's like seeing the answer to a puzzle for the first time...how exactly does this thing work? Then the light bulb turns on:-)

Tire Groove Guy made the rounds of used car lots, looked almost new/perfect from more then 2 ft away or you didn't know what to look for. The friend of a friend made the rounds in a Willys Jeep Station Wagon & had a compressor in it to clean engine bays & rattle can to pretty them up. Also seen a racing slick getting grooved to make it an intermediate/semi-rain racing tire.

We used ti use them on multi spindle automatics for hydraulic components. They give a mirror like finish.

Thanks again

Very informative. Thank you, Mr. Pete.

Thanks Mr. Pete. That was interesting, as usual.

When I watched the previous video I just assumed that what looked like a tack and staple puller was something else. It seemed too easy. So if you know how to spell assume the way carpenters use the word on a job site, well I won't go further as this is a G rated channel, grin... As always very interesting Mr. Pete. I do enjoy the research you do by looking up the patents and etc.

Very interesting !

thanks for the great program Lyle...cheers from Orlando, Paul

I sort of cheated on the watchmakers turn, I have one on my bench that does get used now and then. It is handy to straighten leaves and wheels with during watch repair. I've used it to make a pivot but to do it real well you almost need three hands. One works the bow, one holds the tool and one to rub the rabbits foot so you don't screw up the pivot!

this episode was particularly fascinating..

Morning Lyle

I had no clue on all four. Good one Pete.

Amazing and informative ; as always thanks Mr Pete from old New Orleans 😎

Facinating, keep 'em coming Mr P !

Hi Pete. Again, #1 is a Depthing tool. Some call it a Turning, depending on what country you're from. It's used to mimic or replicate two meshing wheels in a time keeping movement to observe, troubleshoot and/or repair the "leaves"(teeth) in those wheels or meshing pinion gears. True they very closely resemble a "Jacot" watchmakers lathe. Jacot is the name of the inventor and is widely used as a generic word when describing a watchmakers lathe. There are many makers of a Jacot tool. Wish I could send ya a picture. Yes, there are several attachments missing from your example and is very old. You'd really like some of the modern versions that are out today. They're not too common but they're out there. The other tools I hadn't a clue! BTW-I'm no pro just an old retired machinist and hobbyist "watchsmith." Love working on old pocketwatches for folks. It's great fun watching their reactions when I give them their 100 year old timepiece back and it's working. Lights em up everytime.

I am so smart, I decided to refrain from exposing the uses of these tools, so to let others have a try at submitting their thoughts. I also have a bridge in New York for sale.

👌🏼

Tire thing, clear as mud lol

I can't believe I didn't see the electrical cord socket in the tire groover handle

New Subscriber Thank You Pete 👍👍

Your an early riser posting videos at 4am. I'm watching at 4am because I wake often at that time. Can't sleep like I did when I was a kid. Will go back to sleep when my brain fixes itself.

Loved watching your videos for years and have made many of your projects. I would love to send you a personal note and possibly a tool for your mystery tool video. What would be the best way to send you a personal message?

One way clutches

👍

Wish that i would have guessed staple puller then i would have gotten a score of 1😊

I ran a machine at Caterpillar in Joliet that used those type of roller burnishing tools on the hydraulic cylinders. First a floating cartridge would bore the cylinder all the way through and stop. You would open a small door, remove the cartridge, hit start, and as the bar retracted, it would burnish it to size.

Burnishing tool ?

Gauge tool

Jacot you!

Do you have any actual machining content anymore? It has been a year without anything significant with regard to machining.

I have a video on roller burnishing rod bearings. It makes a big difference in how they hold up. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dQnSBPKDuiw.html

They are burnishing tools..

Burnishing tool

Tail pipe expander?

Well I knew the tire tread tool, they were dirty blackened things truckies used them, surely they're illegal now .
