Expandable formal dining table that seats ten and fits in a closet

 by falk

Here is the ultimate in folding dining room tables.  Fully extended, it easily seats ten people comfortably.  Stowed, it's just big enough for you and your laptop.

What's more, the legs are removable so the entire thing packs away compactly — you can stuff it in a closet.  If you ever need to set up a formal dining table for ten, you just toss the thing in the back of your car and go.

The construction of the table is based on telescoping rails built from a series of hardwood blocks.  This is the most interesting and challenging part of the project.

Note: the astute reader may notice occasional differences between the drawings and the photographs.  Where there are differences, the drawings should taken as the canonical source.  The photos are of a prototype, and the design has been refined since it was built.

The attached Sketchup files include complete designs for the table. The second file is the details of the rail construction.

Step 1: Required skills, tools, and materials.

This is a project for an experienced woodworker.

Tools:

Eye and ear protection.

At the very least you'll need a table saw, drill, and router table.  A power sander and drill press are highly recommended and a biscuit joiner would also come in handy.  For the router, you need a dovetail bit, a 5/16" or 3/8" straight bit, and a larger straight bit capable of cutting 3/4" deep, plus any decorative bits you desire for the edges.

A sharp chisel.

A ratchet wrench, extension, and 3/8" deep socket.

Plus the usual straight edges, screwdrivers, clamps and so forth.

Materials:

Two sheets of ¾" plywood, one side good (I recommend oak).

Hardwood of the same type sufficient to make a ½"x¾" border around the entire table: two 8' lengths, two 4' lengths, and two 2' lengths.  If you can't get 8' lengths, don't despair; you'll just need eight 19" lengths.

Hardwood sufficient to make 20 16"x2¼x1¼ blocks.  Poplar is good; birch or maple is even better.

Six table legs, 2½" x 2½" at the top, 28" high (more or less, depending on how tall you want your table to be).  You can make these or mail-order them, which is what I did.  Just search for "wood table legs" and a number of vendors will pop up.  Larger table legs will work just fine, but don't go smaller than 2½" x 2½".

Two table leg brackets.  Just search for "table leg bracket" and a number of vendors will pop up.

Four ¼"x2½" hanger bolts (available at any hardware store). These are two-ended bolts that have wood screw threads on one end and machine threads on the other.  These are screwed into wooden objects and leave protruding threads to allow things to be bolted on.

Four ¼" wing nuts and four washers.

Two 3/8"x3" hanger bolts.

two 3/8" hex nuts and two washers.

Glue, screws, stain, varnish

This is a beautiful project, but very challenging to my woodworking skills and limited tools, but it occurs to me that you could make an easier version by starting with an existing wood table and cutting it in half. Then you could use a couple of 2x4s to make a pair of 8' rails that you could keep in a closet when you are not using them. A pair of bolts and wingnuts on each end of the rails would securely attach the rails to the table halves. A pair of short rails would hold the table together when the length was not needed.

My solution is a lot less elegant, but even I could build it in a day or so. Thanks for the inspiration!

Actually, that's not a bad idea.

Personally, I don't want a dining room in my house because I would rarely use it. I usually eat at a breakfast area in the kitchen or on my couch. How hard would it be to either make legs that fold, or collapse? It's the perfect size table for a coffee table when not in use as a 10 person dining table. I'd use it as a living room center piece. I guess it would be easier and probably more sturdy to just make a separate set of 4 short legs to replace the longer ones when using as a coffee table.
falk (author) in reply to sjl1986Apr 27, 2012. 5:25 PM
Yes, exactly. Just make four shorter legs for coffee-table mode, and just remove the center legs entirely (you don't need them when the table is collapsed).

I think this is a great idea, and just might make a set of short legs myself.

I love this tabel. I am planing to make one. Do you think it would work with cirkel top and the top plate made of MDF?
falk (author) in reply to evamariaFeb 25, 2013. 8:17 AM
I'm not sure what "cirkel" means unless you mean "circle" in English.

You would want to trim the edge of the top with veneer of some sort, but I'm sure it could be done.

making it as a coffe table brilliant
falk (author) says: Feb 20, 2013. 12:43 PM
Another tip: this design has the legs permanently attached to the board, and the entire set comes off as one unit, which is just slightly clumsy. An alternative would be to permanently attach the board to the rails, and find some sort of knock-down hardware to attach the legs to the board. (I'm rather fond of threaded inserts myself.) However you do it, just make sure that nothing protrudes above the board because it would interfere with the sliding rails.
falk (author) says: Feb 20, 2013. 12:37 PM
p.s. the legs can be larger than 2.5"x2.5" with no changes in the design.
falk (author) says: Feb 20, 2013. 12:33 PM
p.s. Ignore the extra holes in the rails in the 4th picture. It was a prototype, what can I say?
falk (author) says: Feb 20, 2013. 11:41 AM
Actually, I realized that you *can* perfectly center the dovetail grooves in the blocks by cutting them in two passes: Cut the dovetail on one side, then flip the block end-for-end and cut on the other side. It's not strictly required that the dovetail grooves are exactly centered, but it makes life a lot easier further on.

This is brilliant. Living in a small apartment means I can't have a big table all the time but with this I can have any size table I need. You saved me thousands of dollars as I was going to buy the Goliath table but know I have to spend a few hundred.
Keep the great ideas coming!

I cannot wait to try this. Looks like an awesome plan!

great brain ...........

Awesome design. I showed my wife and she likes it too, but neither of can see where the rest of the top panels are hidden when the table is in it's "small" form? How do you hide the other panels if they're the same width as the main top panel?

In the hallway closet. :)

Great design. I have an antique hall table the uses a similar approach, along with a folding top. Bit wobbly when fully extended but like you said, able to hold dinner.

Table extenders are available from Lee Valley (probably other woodworking supply places as well) if you don't want to make them. http://www.leevalley.com/en/hardware/page.aspx?p=40139&cat=3,43586

Oh, those are nice. Wouldn't have worked for this table, but would be great for a smaller one.

could i use 100 pound wait limt drawer slides instseed of the wooden mechansim i dont have the skill to make something as amazing as this
casafeliz12 says: Mar 7, 2012. 11:04 AM
This is a great table design, but what about the chairs? Do you have a plan for "easy" chairs?
Matdredalia says: Mar 3, 2012. 4:14 PM
This is an AMAZING piece of work, sir. You are to be commended.

I have to admit, my first thought was "This would be amazing for D&D nights."

"Hey, I'm bringing the Doritos & Mountain Dew!"
"Okay, I'm bringing the table."


Just an amazingly creative piece of work. :)

I must confess that I'm still awaiting the day when someone asks if someone can bring a dining table to some party or another.

Falk,

Amazing ! I like it very well. design is best !

Keep posting new ideas

Regards
Sandeep

AMAZING! What's more, ResourceFurniture sells this design, as the Goliath table. They replaced the wooden rails with metallic ones, so with some work you can either sweat a little and build this table or shell out US$ 5,000. I know what my choice will be!

Heh, I'll be damned. Never heard of that table before. Definitely the same basic design.
CementTruck says: Mar 1, 2012. 5:12 AM
How sturdy is the table?

I really like the idea. You could probably use heavy duty drawer slides in place of all the dovetailing. The end result would be similar I think.

We have a bunch of drawer slides from old server racks in our server room at work that are just ripe for picking. I might have to liberate a few to do something similar.

Great writeup, craftsmanship and finished product!

falk (author) in reply to CementTruckMar 1, 2012. 8:11 AM
It's really quite stable, thanks to the middle legs. I wouldn't climb up on it, but you can certainly serve dinner for ten at it without anybody feeling that the table is rickety.
Truehart says: Mar 1, 2012. 7:28 AM
Very cool! I would also like to know how sturdy it is. I especially like the choice in transportation, lol!
