table, woodworking help needed

post #1 of 5
Thread Starter 
this has nothing at all to do with computers.
BUT, many of you are brillant minded people, so asking here.

this is the picture of the table i'm making for my girlfriend in our kitchen. the one below it is just too large and blocks off cabinets that we need for storage.




the images above were before i started screwing things together, right now its all put together and ready for legs.

here is where i need some advice, i want to put legs only in the back section. then run braces from the front to the back legs.
this way it looks like its just hanging in mid air.
anyone have tips on how to do this correctly the first time? i've used up a good deal of the 2x4s i have had from other projects; so messing up isn't really something i can afford to do at this point.

- edit: extra fyi, the boards were laying on top of the table top.. so what you see under the 2x4s is the top of the L table, was just laying them out. incase someone says (thats going to be backwards.

here is what i was thinking.
side view of the legs



the angled ugly top wood piece would connect to the inside of the sub frame

think that will work well for holding weight and people leaning on it?

that would if we had good supports in the wall. we rent a trailer/mobile home.
because of that wanted to actually make legs but just keep them on the wall side without any in the front.

will keep that on hand, that could really come in handy with some of the projects i do for friends and family.

If you cannot attach it to the wall, then you need to build a trestle leg structure similar to what you diagrammed in your second post. There is no way to build a support structure without one or the other.

However, I would build the trestle legs out of metal instead of wood for stability reasons. You can probably find a cheap desk at a used office furniture store / fleamarket / Craig's List that already has the trestle leg structure you need, so you would only need to remove them from that desk and install them on your project. Those type of metal legs are pretty popular among cheap computer desks, so I would say the odds are good to find some, and they should be cheap. I gave away such a table on Craig's List last year.

Alternatively, you can find a welder on Craig's List to fabricate a set of trestle legs. I had a similar problem with my built-in desk, which although is attached on the ends, the desk is about 10' long so would eventually sag in the middle. I found a welder on Craig's list to build me a custom brace for the middle, and it wasn't expensive - around $30-40, IIRC. A trestle leg would have probably cost more, but not much.

As a side note, I would also consider re-doing your tabletop as a torsion box. Compared to the desktop in your pictures, a torsion box would be lighter, stronger, would stay flatter longer, and would not cost much more in materials. However, the drawback is that you would need access to woodworking equipment (for precision reasons) and you would need a surface to assemble it on that is absolutely flat.
