Okay but like a shim or just a broken discarded piece of 2x4?
Or I guess the chaotic evil version of this is a twig with leaves on it.
I don’t think so, Tim.
time, tool
Do you know for a four legs table no matter the floor it sits on. There is always a rotational position where all it’s legs touch ground at the same level.
For circular tables that are uneven you can just rotate the table until it sits right.
For square tables you may check the 90° angles to see if you are lucky.
Not really how that works, but I dig the enthusiasm!
That’s just so wildly not true that I can’t believe you didn’t work it out for yourself in the time it took you to type that up.
To test your theory, envision a floor that is a perfectly level pane of glass. Then picture a 4 legged table where one leg is just an eighth inch shorter than the other 3.
You can spin that table all day and there’s never going to be a position where it doesn’t wobble.
@daniskarma@lemmy.dbzer0.com is citing a mathematical proof that basically states if you have a table whose feet form 4 points on a flat rectangle, that table can find a stable resting spot anywhere on an uneven surface only by rotating the table, you do not have to translate the table, only rotate it.
Your example, while practical, breaks that model because it only works if the continuous surface is uneven and the four independent points are coplaner. If you make the reverse true, with a table that has 4 even legs and put it on a floor that can be described as two triangles (what you would get if you connected 3 even length legs and one shorter) you could rotate the table to find somewhere all four legs touch.
This is why it is very important for us woodworkers to make table and chair legs the same length, or failing that, add adjustable feet.
Yep, it works the other way around. Even legs uneven floor.
Interesting that it works the other way…I assume that in that scenario, there’s also no guarantee that the table would be anywhere close to level in whatever position eliminates wobble?
As a woodworker, I’d do the same. Granted it would be a piece of wood with matching dimensions to the foot, but still just a piece of wood.
Just look at the guy… he’s carrying ALL of the Ace Hardware bling!
He’s still a babe.
did you manage to sell any of them pocket hoses too?
Jokes on you I had to go buy a kitchen sink faucet and replace it 1st thing in the morning before going to bed for my night shift cause ours broke yesterday evening 9pm. I’m a IT guy with 0 plumbing skill.
Now you have 1 plumbing skill. :D
Wood? I just keep folding cardboard until it’s the proper thickness.
Cardboard is wood with extra steps.

I’m sad that guy went off the MAGA deep end.
Nooo, what D:
To be clear, I’m talking about AvE and not red green guy
Ahh good to know
That also looks like me in college when my friends would complain that we didn’t have anything to smoke out of.
A cool thing is, you can achieve the same effect by rotating the table in a circle (if possible) until you find a stable angle, since for 4 points on a circle there has to exist at least one rotation angle where they are on the same elevation.
Problem is, that you might have to move the table legs through the floor to archive the desired result
I’ve done this with my dinner table several times.
There’s no guarantee you can draw a circle through the bottom of the four legs of a table (opposite legs can be off in the same direction). Also, most floors are not perfectly flat, therefore you can’t assume the floor is at one elevation.
Is there mathematical proof for this? It sounds like it could be true, but also sounds like you could actively create a floor which it wasn’t true for
This is one of those things that works in a simulated environment but not in practice in the real world.
It does work in the real world, as long as the floor is the problem, and the table is perfect.
Most of the time at a restaurant, it’s the table that’s been beaten up and is no longer even.
I’m pretty sure this doesn’t account for any floor that isn’t a flat plane.
It doesn’t require a flat plane ground, but it does require the table legs to be equal in length
Yes there is. The wobbly table theroem. https://people.math.harvard.edu/~knill/teaching/math1a_2011/exhibits/wobblytable/
I don’t think that’s exactly right. to create a plane you only need 3 points and 4th point can be on a different height than that plane. A different thing is when the ground itself is uneven and you manage to make both fit to the same shape.
This requires the legs to be all the same height and the floor to cause the wobble. That doesn’t happen often irl, but I’ve done it a few times and it always makes me happy when it works
Me, with a few “POGs” in my pocket. Wobbly furniture beware!
(Jk those things are relics now.)
I remember the days when you could go to hobby stores and find multiple troughs full of them.
Toilet paper for me
I use a bidet
I use my fingers then I rinse them off in the sink.
Rub it under the table leg to balance the table.
folded paper napkin. they’re all wood products.
