go look at books from home depot. I do that a lot.
go get your mother/grandmother's card table and reverse engineer it

(take it apart and recreate it using your new measurements.)
i don't know any websites or vids but you can surely put hinges on it maybe
Do a search for ';folding table legs';, and you can find sources for hardware that you bolt or screw to your own table. As far as the table itself, If you're trying to make a portable support for a train track, I would go with as light a grade of plywood as you can, and make a stiffening frame under it of 1 by 2s or so to give it a bit of stiffness. If you put a short block of 1 by 2 every 2 feet along the edge, and then a 1 by 2 on top of these that runs the full length of the table, it should make a reasonably lightweight table that still is strong enough to stand up to the load and to being moved around all the time.
The same way you make a pretty lady, but use protection, sicko!
Actually those decorating tables you can get from most DIY shops might do the trick. They are cheap too.

If you bought two and put them side by side thry would be the size you want. It would probably work out cheaper than buying the raw materials to make one.

You could place simple wooden catches underneath between the tables to strengthen
