Hello everybody! New member here, although a long time DIYer (computer fabrications mostly), this is my first endeavor into wood.

So, i want to make a meeting room table for my brother, but im afraid the base i have spotted and the tabletop, may cause stability issues (wobbling and easy to tip over).

So, the table top is 130cm wide by 246cm. The surface is also 3.8cm thick, resulting in total weight of about 70kg.

The base i have found and like measures 74cm tall, 153cm long and 58cm wide. The base designer claims it can accommodate tables up to 200cm long, but doesn’t mention width limitations.

Do you think the table will be unstable?

Regards,

Michael

I think it would be way too narrow. A lot depends on the design, splayed legs would be more stable than straight ones.

Seems like to much overhang to be stable. Could you build your own base?

Barfastic,

I agree that the base seems too narrow and not long enough. The distance widthwise of the load bearing points (at the floor) of the table base should be no less than 69 cm apart for a 130 cm wide table top. The lengthwise minimum distance of the load bearing points (at the floor) should be no more than 186 cm apart for a 246 cm long table top. These dimensions bring the edge of the table top within 30.5 cm (12 inches) of the load bearing points at the floor, the minimum distances that ensure a stable table. My source is Don Stephan, who provides a rather comprehensive discussion of design parameters for dining tables and nothing in my experience contradicts his recommendations. See Page 9, “Table Base”:

Without knowing more about the design of the base, it is difficult to say whether the table base you are considering will resist or allow for wobble. Generally some form of bracing that imparts rigidity to the table legs is usually needed to reduce wobble.

Have your say...
