Table project design questions

Hi yall,



Just a question or two regarding table design.



I've agreed, somewhat stupidly? ha not really, to make a dining table for my sister.

She has a few different designs which she likes the size of, and so I need to enquire about the design/engineering of them.

Below is one of the styles she likes. However she is more fond of a lighter feel to the table. Which as far as i'm concerned, hardwood top = weight = sturdy sort of legs. I see alot of these styles of table with steel square legs tacked on, obviously to have a lighter feel to it. Now i'm probably going to push her for a single slab top, so thickness will be 50mm, or thereabouts. If I did have similar legs to this, what sort of thickness of wood would i need to support a top. (1800-900 or thereabouts, final dimension to be confirmed).

Also, in alot of these tables i see no apron. How would this work for keeping the surface flat and negating movement. Or should i just have a hidden apron.







Hope that doesn't sound to convoluted.



Cheers,

Lachie.
