We've had thoughts about finally revamping our back yard. Life has

anyway.

I'm thinking primarily of an outdoor dining table; simple, farmhouse
style. I'd like it to be over-large, but I'd also like to be able to put
it in a shed for the winter, so I'd probably build two normal-sized
tables instead, with removable legs.

So firstly, is this a stupid idea? Will I simply be building myself a
neverending project; one that will need refinishing every year or two?
We live in NY City; a pretty "versatile" climate with high humidity in
the summer, and of course, rain. The table would sit on concrete. We'd
keep some sort of fabric awning/umbrella over it, but nothing that would
truly keep it from the elements, (except in the winter).

If it's not stupid, what sort of wood should I build it from? Are there
perhaps plastic "cups" that are designed to protect the bottoms of (say)
4x4s where they would touch the ground? If I were to use metal fasteners
(for the legs, plus possibly pocket screws elsewhere), would those be
problematic over time?


So many options. Wood choice depends on budget and how long you want it
to last. Anything good for decks is probably good for the table. Look
at some of the wood here for ideas http://www.advantagelumber.com/

Avoid pressure treated. Do you want to put your food and beverages on
chemically saturated wood? Even construction grade lumber will get you
7 to 10 years with minimal care. some of the exotics will last 50+
years with no treatment. Stainless steel screws, of course.

Putting it away in winter is good, but a blue tarp will give you plenty
of protection.

I've had good results with cypress, spanish cedar, mahogany decking
material, and tiger wood. UV is the worst factor for it turning grey so
use an oil with UV protection and try to keep it covered. Next is
ground contact. Any sort of rubber pad makes a difference keeping the
end grain from contact with dampness.
