I like your little note on the clamp rack. One of my soccer-playing grandsons has a shirt that says something to the effect of: "Don't practice till you do it right, practice until you don't do it wrong".
In regards to the copper cleaning, I worked in a restaurant that had copper hoods over the stoves and I was tasked with cleaning them. The thing that I found works the best and WAY FASTER than either of those was a lemon cut in half, dipped in salt on the cut side. Easy to hold and a great scrubber. The copper transformed right before my eyes, it was a mazing.
Cool books. My father did thirty years in the submarine service. Electric Boat employed a lot of my friends parents. Some of the best welders in the world.
My diesel cylinder head machine(mill) has an air float cradle that weights 600 pounds plus 250-400 cylinder head weight and you can easily move the entire assembly with your little pinky when air is applied. Great video Tom!
We have a trimos heightgage at work with a similar airbearing so its not as bloody hard to push around. What do you say Tom, DIY squaremaster/heightgage/tesaheight-ripoff with airbearing and granit column?
I used to make copper cooling blocks for my water cooled computers back in the day. I used citric acid to get tarnish and/or oxides off the copper and it worked like a charm.
Great content Tom! My first experience with air bearings 1977, our in-house lead toolmaker designed, developed and built a radius grinder with air bearings. We ground a lot of carbide tooling that needed to blend to the ID or OD within +/- .0001 , very little polishing was needed mainly due the air bearings! Great stuff
A telephone equipment provider used air pads to float entire switch frames into place from a temporary building to a permanent setup, probably 50 years ago. Simply leaning on the frame after it was on air would move it easily.
Tom, great video. FYI, the AF uses air bearings at Cape Canaveral to move enormous 100' tall blast doors and huge steel assembly structures that weigh many tons. Really cool.
That little red book which you so quickly glossed over has stuff in it which, if correctly and usefully applied to a submarine, will have classified results. ;)
I was happy to see the length of the vid., also I really dig the door knobs on the colorful shop doors that are over your right shoulder in the beginning. Thanks for the video.
One of the aircraft plants (North American Aviation, IRC) had a large building with a very flat and smooth floor and they moved massive structures (assembly jigs and fixtures) around with bearings. Air bearings are probably used in many other plants (satellite production) for ease of movement and no shocks to the object when lifting and "depositing".
I used to work in a shop where we made wood die models for the automotive industry. We had a air bearing cart that was about 5'x8' that was used to move the models around the shop. It could also adjust the height so that the models could be slid from the cart onto granite surface plates.
Air bearings are faszinating. In the high voltage lab of the university I was there were these huge 10m+ voltage multipliers and these weighing tons were just shuffled around on air bearings.
Thanks for the meatloaf Tom. On a ship in the late eighties that had to stow things in odd nooks and crannies, the metal cradles had feet that could be supplied with compressed air to make it really easy to move things around. Once in position the air pressure was cut and the object secured.
Denver's old Mile High stadium used water bearings to move a large section of the stands to reconfigure things for baseball or football. The Wikipedia entry says the structure weighed nearly 9 million pounds, and there were 163 bearings.
Hay Tom . I did my time as a Machinist back in the early 70's and did a lot of spray welding on pulp and paper equipment a lot of hard chrome build up on large shafting 6" plus and now suffer from nerve damage and makes for long painful days that medication dose not work I am just saying stay away from this stuff as it is absorbed thru your skin as other heavy metals . I always give a thumbs up and like all your content
Tom I watched every meatloaf I love it I know everyday life gets in the way I too have a channel and yes everyday nonsense has slowed me down a little👍🏻🇺🇸✌️
Mid-'82 was the changeover. They ran both types that year - early-run pennies were copper, later-run were zinc. Easiest way to determine which is which is by weight - the zinc ones are lighter than the copper.
Hate to break it to you. That penny was just one of five known prototypes. Worth hundreds of thousands... unless cleaned in a salty vinegar solution, then the value drops to $ .01
When you get the old “Navel” rust removers, either the pink or blue (other than the colors they are the same), they’re jelled phosphoric acid. I believe the concentration of acid is higher though. I’ve got so many KantTwist clamps. Yup. Those tiny ones are great too, though I epoxied one swiveling jaw to the frame. That wasn’t intentional! It would bother so much that the pin holes don’t match up properly. If I did that, every time I looked at it on my equipment, it would bother me more.
Another great show Tom. cleaned some copper marine cooling tubes with vinegar only no salt and left em over night came out new. the klean strip etch and prep is perfect for hot blue solution that and manganese oxide and some iron powder they have some handy stuff and in bout every hardware store. adam said he's been doing that spray welding for years.guess he wasent kidding he must be 120 or so now.
Years ago I made an air-hocky tenoning jig for my 10hp wood shaper. Jig table weighed 60#. I could take giant panel-raising cuts freehand using a 6" cutter and a rub collar. This was safe and stable due the properties of mass & inertia.
The other beauty of her hammer is the beautiful thinness of the wood handle. Maybe spend a few minutes on the belt sander to really “nail” your tribute?
A quick note on phosphoric acid and where to get it. Look for products used to dissolve Limescale, for example to use on coffe brewers, bathrooms and such. Not only is it really great for copper and brass, but it's also an amazing rust removal remedy for steel and iron. Sometimes even better than evaporust, wich says something... Not as safe, but twice as fast.
I had a valve guide machine in my automotive machine shop that was basically a large drill press with a air bearing table that was about 12" x 36" it held hundreds of pounds and you could position it with your finger.
Get a 1" thick steel plate big enough to mount your lathe or miller on and drill and tap a hole in the center to take a quick connect air fitting. Just add shop air and slide your machine tools around to conveniently get them out of the way. Don't get them moving too fast, though. I suspect they'd be nearly unstoppable at some point!
Not sure who doubts air bearings' load capacities, but Volvo runs a crash-test lab with a movable barrier block that can withstand truck crashes up to 60 mph. When they move the block, air bearing are what makes moving it a routine procedure.
I have seen load-carrying pucks with rings of very small orifices around the perimeter, fed from a common gallery annulus, and angled such that air is directed inward. There is probably a patent on that.
Most everyone enjoys meatloaf, it is easy to prepare,can include anything eatable, holds up against every known sauce,and has absolute repeatability, durability, an essential .
Locomotive companies use air floats to move their locomotive frames around during the manufacturing process. The ones I've seen have ~3" 90psi airlines.
Yes that is Phosphoric acid - clear green. Takes rust off Iron/steel stuff and plates Phosphorus on it. Leaves it a dark gray. Will flash rust if not washed and oiled. It will eat it alive also if not in a short time and washed. Better rust removers now. Kant Twist - think of a C clamp and you turn the crank and the work rotates out... These won't.
For a moment, I was afraid you were going to show me what was embedded in the lung tissues of the metal sprayer. I once helped move a 6ft. by 9ft. granite inspection table between two buildings with air bearings. Sheets of PVC were laid out along the path of travel so that the bearings wouldn''t crash. The biggest problem was stopping the damn thing before it crashed through the wall of the target room. I don't recall the weight of the granite table, but it was massive. Couette flow exists between the disc and the surface. From my old fluid dynamics days... That must be a photo of Mare Island in Vallejo. Best Regards, Tom.
When you moved the Conversion Factors book to reveal the one underneath, I initially misread it as Shoplifters Handbook .. LOL. I thought to myself, this should be interesting 😲
Meatloaf,meatloaf,meatloaf!!! Im no machinist but still find ur videos fascinating.And much of what i learn is applicable in life,in general. Thanks for sharing,man.(yes,Abom spray-welding LOL)
While I agree with your assessment that the phosphoric acid did a better job... as someone who has spent years restoring older (usually Italian) race car electrical systems, I'm always a bit leery of using an acid on copper as you can go from clean to gone quickly, depending on the level of oxidation present. An old timer's solution is closer to your home brew... simple ketchup. Fill a container with ketchup and bury your copper items (most commonly I see Marelli fuse blocks for ceramic fuses) in ketchup and leave it overnight. Copper cleans up nicely (slowly too), minimum metal loss and won't hurt plastics or bakelite.
Your ruler to me looks like a broddling stick (a broddler = a handy tool used for anything; poking in, hooking out, holding or chipping a 6th finger). Mine is an old toothbrush minus the brush end but it can be anything.
Air bearings reminded me of one of the pipe organs at Luther College. The entire organ was built on a frame with air bearings on the bottom. Being a pipe organ it had a ready supply of air and could move as far as the electrical cord permitted.
Being an architect, we ususally write into our specifications for roofers to use white cotton gloves when handling copper or pure aluminum sheet for roofing applications to avoid finger prints. On the other hand the rumor was when our State capitol building here in Jackson Mississippi was built in the 1920's construction workers urined on the capitol dome to expediate the patina process.
I have inexpensive (SPI) vee blocks which are ground sufficiently flat that they will float across my AA+ plate with no holes or air feed, just the air trapped when setting them down. The first time it happened was unintentional and quite startling, it damned near wound up on the floor!
The copper colour coins in the € colection ie 1centimos, 2centimos and 5 centimos are actually steel cores with a very thin copper coat, I pick them up regularly metel detecting on the beach and they are just rusty steel discs.
So not only This Old Tony can timetravel...
but he does it with style and with Clickspring.. #JustSaying
Sure! Just don't try it in metric.
TOT is just the dealer. The one who makes time crystals. I also hear he throws pizza on his roof? No idea why tho.
Fairly sure we're dealing with an immortal.
you are all wrong That's Abomb'29

I was sort of getting depressed. But now i feel like i have a friend back. Thanks for everything Tom. You're the best.

Skitch2310 works for brass too.
1982 was a transitional year, both (copper pennies 95% copper 5%) and zinc pennies (97.5% zinc 2.5% copper) were produced!
Another great Meatloaf. Thank You Tom! I am watching from the U/K.
Glad to see you back producing content. Thank you!
Sorry to hear of Carla's passing. 🙁
Tasty meatloaf Tom! Love those air bearings.
ATB, Robin
ROBRENZ Tom dusted off his vid making skills. Was wondering if you were working on anything for us?
Cool books. My father did thirty years in the submarine service. Electric Boat employed a lot of my friends parents. Some of the best welders in the world.
"memory jogger, I nearly forgot that one", classic Liptonese humour.👍

What do you say Tom, DIY squaremaster/heightgage/tesaheight-ripoff with airbearing and granit column?
Do it! Do it! ^^
Sure. Lets do it. I can get some granite parallels and off we go.
Cheers,
Tom
I used to make copper cooling blocks for my water cooled computers back in the day. I used citric acid to get tarnish and/or oxides off the copper and it worked like a charm.
That is hilarious. Totally looks like ole ABOM
way too skinny and small for abom
So glad to see these back. Really enjoy your channel and even learn a lot to include with enjoyment. Thanks Tom.
Great content Tom!
My first experience with air bearings 1977, our in-house lead toolmaker designed, developed and built a radius grinder with air bearings.

thanks for the air bearing segment. it's a term i hear get thrown around and seeing it in use was neat.
So glad Meatloaf is back. Mondays haven't been the same. Thanks for all the knowledge.
Tom, great video. FYI, the AF uses air bearings at Cape Canaveral to move enormous 100' tall blast doors and huge steel assembly structures that weigh many tons. Really cool.

I've always loved Monday night meatloaf.
Air bearings are faszinating.
In the high voltage lab of the university I was there were these huge 10m+ voltage multipliers and these weighing tons were just shuffled around on air bearings.
Thanks for the meatloaf Tom.
On a ship in the late eighties that had to stow things in odd nooks and crannies, the metal cradles had feet that could be supplied with compressed air to make it really easy to move things around. Once in position the air pressure was cut and the object secured.
This bit of loaf was like another chapter in your already excellent book. Thanks.

Woop woop. Meatloaf is always exciting Tom.
Hay Tom . I did my time as a Machinist back in the early 70's and did a lot of spray welding

For the record, I also love the meatloaf.
I like the big air bearing rotary tables, you can move tons like it isn't even there.
Hate to break it to you. That penny was just one of five known prototypes. Worth hundreds of thousands... unless cleaned in a salty vinegar solution, then the value drops to $ .01
Good one!

copper 3.2 grams , zinc 2.5 grams

Penny Brite is a copper and brass cleaner that many jewelry makers use. A little elbow grease might be required.
Great to see you back Tom!!!
I like the Meatloaf. I also want to see the rest of the Project Egress pressure relief valve episodes.
Yes!
I had a valve guide machine in my automotive machine shop that was basically a large drill press with a air bearing table that was about 12" x 36" it held hundreds of pounds and you could position it with your finger.

Zinc pennies were introduced in 1982, and both copper and zinc pennies were produced marked 1982
John
air bearing set was neat as heck.
I have seen load-carrying pucks with rings of very small orifices around the perimeter, fed from a common gallery annulus, and angled such that air is directed inward. There is probably a patent on that.
I thoroughly enjoy all your videos thanks for sharing Tom.
Most everyone enjoys meatloaf, it is easy to prepare,can include anything eatable, holds up against every known sauce,and has absolute repeatability, durability, an essential .
“I just had to put a little english on them” - Thank you for helping me with my english!
This is a term in pool, for applying spin to the cueball. However, it is not used in the UK.
Locomotive companies use air floats to move their locomotive frames around during the manufacturing process. The ones I've seen have ~3" 90psi airlines.
I miss it when you don't post videos. Keep coming with your excellent content.

Abom Time Traveler extraordinaire 😂😂😂
Mick Curry 😂 I was thinking the same damn thing when I saw that picture, lol
Great Minds Brother!!
Let's wait for Adam's rebuttal 😂😂
GrampAbom79... Lol
What an outstanding meat loaf. Seen them all this was a gem.
Great video and I finally got to watch it. Spent the day on yard work and hauling the boss lady around so I did not even know a new one was out.
You are correct about the design of the brass hammer...I am going to make a mold to make hard lead hammers in that pattern. ( 18-20 bhn)
I have never seen a tool holder like that, cool.
HP Sauce is/was the common household method to brighten up pennies over here in the UK.
Lol. Lipton's scale lives a harder life than a rental car! Thanks for the Meatloaf.
Liquid solder flux works excellently to clean copper as well
More cool stuff. I love your Meatloaf videos. I always learn something new.
in the uk out tomato ketchup (red sauce) brings up copper and it's sticky, so i guess you could clean things that are vertical.
Abom is a time traveler? Taco bell hot sauce will make them pennys shine
Must have done a collab with Tony we don't know about.
Taco bell hot sauce? Think that's one of the most benign sauces that I eat. Maybe I should start selling my excrement as copper polish?.....
@@PapiSmerf give it a try on a tarnished penny.
When you moved the Conversion Factors book to reveal the one underneath, I initially misread it as Shoplifters Handbook .. LOL. I thought to myself, this should be interesting 😲
Oh my gosh, Adam Booth is a machinist vampire! (We all knew it!)
Meatloaf,meatloaf,meatloaf!!!
Im no machinist but still find ur videos fascinating.And much of what i learn is applicable in life,in general.
Thanks for sharing,man.(yes,Abom spray-welding LOL)
sparex no 2 is also an option for cleaning copper. just dont use ferrous implements in the acid or everything gets copper plated.
I've been really enjoying the recent content on this channel. Keep it up!
Hi Tom, I use to use Airfloat pads to move machinery around our shop when setting up our work cells.
Play Safe From Elliot Lake Ontario Canada.
I love the meatloaf! 👍
This maybe a ' have to of been there moment' .I was watching this meatloaf on the big tv
Pressed the wrong button.
Thanks Tom!
Always learn something new about gear or techniques on your meatloaf episodes. Good stuff!
A quick test for copper verses zinc pennies is to drop on a hard surface. Copper rings while zinc makes a clicking noise.
👍 thanks. Always learn something from these episodes.
Hurrah for MNM! cheers!

Tom U. does nice work on the machine tags. At one of my old jobs they had many air ride pads for moving large machinery around.
Ketchup cleans copper really well. And it's cheap.
You are 100% right. Meatloaf is the ice on the cake :) Thanks a lot Tom!
Excellent batch of meatloaf as always! Thanks, Tom. Would love to see a wide shot of the shop just to get a feel for your layout!
Fun and informative meatloaf. Thanks Tom.
Damn, Adam's a LOT older than we thought!
