did you mean liftbowl > tilthead?

I used the wrong term.

When I said "regular maintenance" I meant maintenance that should be considered "regular" or normal, after a decade or more of use... not the typical meaning of "regular maintenance" meaning frequently occurring out of necessity.

the lid is crucial for insulation for yetis. Test again with lids on both and report back for science? I am curious because I have always been satisfied with yeti, besides the price tag. Always looking for other vacuum insulated cups and such because from what I understand that's what really helps. Found some vacuum insulated cups but the base isn't vacuumed, so they float upside down when submerged, and they don't work as well because of that air bubble but still work okay.

I doubt it's regularmaintenance by the manual, it's most likely irregular maintenance because it's been in use for so long. I doubt that machine needs any regular maintenance apart from cleaning. Tbh if there's metal gears, they expected it to stay sealed for-life, kind of like how most manual car gearboxes have the same oil for the life of the car...

I mean, it's not bad to swap out the grease, but in most cases itwon't really make a difference if it's just a sealed metal reduction transmission.

I have one of those chrome and green ones handed down to me from my Father. I don't use it much because it's pretty big. Like the anti-aircraft guns projectile on the Missouri big.

Not just the little people, the large people too

Craigslist type websites, office closing auctions/sales.

I got an amazing Leap 2 for some $250, about 4 years ago, but it took me a few weeks of daily refreshing my local second hand online marketplace.

When I was searching I’ve seen cheaper ones as well, just in a worse condition (mine was like first or second private owner with leather finish, so higher value). Especially at an office demobil store.

I find the comments ...panning... the Lodge enameled cast iron a little bizarre. I have a few Lodge items including ghe enameled dutch oven and it has been fantastic with no chipping. And I'm not the gentlest. Of course I suppose it could just be luck. If money is no object then you couldn't go wrong with le creuset either.

There's a company that makes a sort of heat sink... A oval made from high thermal index alloys, plated with gold. Soaks up a good bit of heat without diluting anything. Not enough heat for my boiling tea, but it gets my coffee exactly where I want it. I think Coffee Joulies is the brand.

We have this clock! It’s been passed down from my grandparents to my mom to me and is now in our son’s room. 4 generations of use (so far!).

Same. I'm pretty rough and tumble in my daily and it was marred within two days. Stainless has held up great, and the chrome just started coming off the latch button this year.

Denture tablets are the way.

Thermos funk tends to be from volatile oils and a layer of casein from dairy. The dairy layers up, provides a home for oils which get rancid and gross. Denture tabs were literally designed to combat biofilms exactly like these.

I do one tablet in the mug and one in a cup with the lid gaskets, soak a few hours and a quick hit with a bottle brush. Keeps the mouthpiece sparkling, hasn't damaged any of the gaskets.

Found mine on Craigslist.

Little over 7 tons of cast iron; it weighs over 14,360 pounds.

No steel though.

Yes!!! It takes a little longer than if I boil it. But it never burns. I don’t have to baby sit it. I put the rice in and walk away. Perfect rice every time.

I've also used mine for five years now and adore it.

They use a layer of gold foil in their vacuum void, which reflects something called blackbody radiation. It's near-infrared light that anything much above absolute zero emits, and is the main way to lose heat once you take conduction out of the equation.

You definitely have to make sure your beverage is at drinking temperature when you put it in - I just brew my tea to allow for three ice cubes and it's at the perfect temp for the next eight hours.

It's also important to clean the lid properly, which seems a chore but takes about one minute. I like to use unscented denture cleaner with mine, just disassemble and drop it all in, wait two hours or so and rinse.

They also make excellent food jars and amazing high-end rice cookers.

Seems Aeron is a very popular recommendation. Any suggestions where to look for used?

This isn't surprising. The tumblers have single wall plastic lids compared to an air tight and insulated lid on the Zojirushi thermos, and they're meant for different use cases.

Thanks for the info. I'll try to find a used one. Any suggestions where to look for used?

Thanks I'll check that subreddit

Are looking ebay, facebook market place to find these?

Any suggestions on where to look for a used one?

Replace the metal worm gear with the new plastic one, too. It'll fail 10x more often but when it fails only it fails. When the old metal one fails it'll take the whole machine with it. It's a great example of engineering resiliency into the product.

Edit: and the motor contacts. Those are wear parts.

I have a Zojirushi, and it retains heat too well that made me buy a Yeti tumbler lol

To be fair, most things are better than a Yeti.
