Instructables
Using extruded aluminum, some pre-fabricated fasteners and a couple of pieces of nice bamboo plywood we put together a few good looking conference tables.

Step 1: Materials

1. Materials

The table frame is constructed using a proprietary aluminum section system called 80/20. You can use 80/20 extruded aluminum to make just about anything. www.80/20.net has a good site that sells the stuff and all the accessories - but its for sale from a wide variety of retailers online. Basically its marketed as an "erector set for adults". It has a T shaped grove in it that allows you to attach a wide variety of fasteners, angle brackets, hardware and fun stuff - you can put it together however you like. Any similar system could be used - have a look at what you can find.

The table top is made from Plyboo - a bamboo lamination composite. You can use any materials however to make the top.

These materials were selected as they are readily recycled at end of life. They may also 'live' several lives in different configurations.

2. Tools

Assembly: Allen key to fit screw size chosen.
Drill: To create screw tapping holes in legs for foot fixtures and to drill screw pilot holes on underside of Plyboo tabletop
Tap: To suit foot screw size
Saw: Hack Saw or suitable drop saw to cut sections to length. (you may be able to get the material supplier to do this for you)

3. Dimensions

These will vary depending on the size of table you require.

Table in this sequence of images is 4' x 4' foot and we have made 3 to form a boardroom table thats 12' x 4' which can also be arranged into several different combinations of 1, 2 or 3 units when required.

You will need 4 equal length leg sections. The height of the table top from the floor was 29". To determine the length of the leg sections subtract the thickness of the table top material and the foot fixture from 29".

You will also need 2 pairs of equal length table top support sections. We determined the length of these by allowing a 5" order all around from the edge of the table top.

4. Assembly

Check that you have:
1 x Table top
4 x leg sections
4 x table top support sections
8 x triangular 4 screw brackets (with 32 screws and 16 slide fixings)
4 x right angle bracket (with 8 screws and 8 slide fixings)
6 x right angle bracket with slide nut (with 6 screws and 6 slide nuts)
4 x screw in foot fixings

Great looking tables. Simple and strong. I was looking to do something exactly like this. A couple questions: Did you do any finishing/coating to the bamboo table tops?

Any tips for cutting or screwing into the bamboo? Does it splinter or split easy?

Its would be so cool to make a pingpong table out of plyboo.

Do you have a rough cost on these tables? 80/20 is usually quite expensive, I'd guess you had $150/per table invested here.
top 140 finished and painted base about 250 not so cheap - we had a sustainability goal not an economic goal .. you could look at using other cheaper systems ...
There's a dude out in Alameda who makes some awesome stuff out of Plyboo. His company's called Modern Bamboo. http://www.modernbamboo.com/

A couple things. Are you going to add a method of locking adjacent tables together?

Also, even though bamboo is a more sustainable resource I wouldn't use it for this purpose. There are tons of old doors you can get at places like Urban Ore that cost much less. I'd think the aesthetic and pre-worn look would be better for a shop environment.
I checkout Modern bamboo, they have cool-looking products. Doors make greater table tops. One comment on Urban Ore though. There was a time their prices were actually reasonable. But last time I was there I could not believe my eyes! Everything had a green tag (or may be it was red) and the prices were same as new!

plyboo looks great. Where'd you get it and how much was it?
