When reading [xenzag's] most excellent 'Two Tables, Four Legs'
idea, I noticed that leg levelling wedges were mentioned to
stop the inevitable table rocking (which we've all
experienced). I suggest selling packs of 4 small buckets filled
with specially selected 'table levelling' sand. Jam each
table
leg into a bucket, adjust the table to your desired position
and VOILA! no more rocking table.

How about a set of tiny extending legs upon each leg which can be adjusted in length? Imagine a pliable, high friction rubber gasket. Surround this with a tightening metal wingnut, such that the collar can be placed upon the bottom of the leg and securely attached. On the outside of the collar place four tough stiff rods with some high friction material where they will rest on the floor. Each rod can be adjusted in height by turning it. If this is insufficiently precise each rod can have a similar device connected to it. |

If you use sand + cement, once it is stable, add water =
permanent solution! |

Until someone moves the table across an uneven floor or
deck. |

Approved {+} (even though over time, the legs will settle down at the bottom and push the sand to the one side. |

High tech version has a tiled or mosaic floor, each tile of which is mounted on top of a hydraulic extender. Laser scanners mounted in the corners of the ceiling continuously scan the volume of the room, auto-detect any approximately horizontal flat surface in the space, detect the support structures connected to said flat surface, and extend or retract the appropriate tiles until the surface is horizontal. |

I think to make this work instead of a bucket you'd
just use a little packet or bag of sand. You'd still
get
the
leveling effect but wouldn't 'have to worry about
the
sand getting all over. Plus you could attach them
to
the table at the factory and they wouldn't look as
weird as the buckets. |
|
| |
Or the bucket assemblies could be put into a
recession in the table legs and still work just as
good. Have the buckets all lower to the floor by
gravity and the table actually be supported by rods
that extend into the sand in those little buckets.
That was all you see is these self adjusting table
legs that don't drop off when you move the table. |

+ yes. so much better than folding up matchbooks
to level the wonky leg! |

Would go far to prevent spillage of Ian's Two Cups of Coffee, should
we find them. |

if the sand were appropriately dense the tendency would be to float which could /tend/ to level the table. |
|
| |
Wouldn't that tendency be contingent on the sand being agitated
enough to behave like a fluid? |
|
| |
Perhaps this furniture would be most suitable for people with tics
such as restless legs - they could be harnessed to agitate the sand
and thereby level the table. They wouldn't have to be there all the
time,
but could be called in periodically, like piano tuners. |
|
| |
What if your table has 3 legs? Or 6? This could be a fundamental problem that undermines the entire basis of this idea. |
|
| |
To make the floating effective, have a fitting to connect an
air compressor to all four corners at once to blow air in and
fluidize the sand. Once it's level, disconnect the sir to lock it
in place. Otherwise, if it's floating and you put a heavy load
on one side it may start to list. |

Sounds like a plan to me. I love to dump moist buckets of sand
over at the beach. BRING it home, if there are extras, I say.
Play "beach day" and surprise the littles. |

//What if your table has 3 legs?//
3 legs will be inherently stable (might not be level...).
On that note, for any number of legs, you could keep one
without a sand bucket, to provide a fixed point of reference
(generally, the longest leg or over the highest floor-point). |
