building a wooden computer table

Hi,

I'm thinking of building a wooden computer table, probably out of teak
or similar wood. I'm in Bombay, India.

Wooden tables over here are manufactured so that there is a sort of
frame on which the table top is fitted. Once the table is assembled,
this frame extends vertically down an inch or two on every edge of the
table, and is 1/2 an inch thick or something. I hope this description
is clear. The purpose of this is to increase the strength of the
table. The concept of flange is similar, but I don't know if that term
is normally used here.

An important consideration is that I need to have a keyboard tray
mounted underneath the desk. This would be simpler if the table top
was flat, as then the extended edge of the table would not interfere
with the motion of the keyboard tray - for example, it would be hard
to make the keyboard tray slide out straight if the table edge was not
flat. One way around this would be to add extra wood under the
desktop, so the keyboard tray could be mounted "further down". The
other option is to just have a flat table top, but I'm not sure if
this will be sufficient for a strong and stable table. Perhaps there
are other ways of reinforcing the strength of the table?

Anyway, the purpose of this message is to solicit opinions from people
who are more experienced in these matters than I am. If you have
thoughts on the matter please let me know. Also, please CC me on any
reply at the email address above.

Regards, Faheem Mitha.

This is probably the easiest route as long as the tray and keyboard will be
above knee level and at a comfortable height to use. If that's not possible,
then all I can suggest is an enclosed keyboard tray (which is what I use)
that sits on top of the table and your monitor or something else would sit
on that.

Excellent description. I've always thought our East Indian brothers
had better English skills then us in the west.

The frame below that you speak of is what is commonly called an apron.
It is fairly important to the structure of the table. Yes, you can use
a simple thin flat top but it will most likely present many issues.
So, I would propose this approach; use a frame (apron) but have a
drawer that is integral to the apron as described below.

Build the frame (apron) such that is has 2 additional hidden members
under the table top that run parallel to the edges of the drawer which
will hold the keyboard. These should run all the way across the table,
securely attached at each end to the outer frame. Cut the frame member
where you will have an opening for the drawer. drawer so the cut out
piece will become the face of the drawer. Build the actual drawer with
the sides much lower than the face and this will allow you to add
another hidden piece of frame that is much shallower than the frame,
applled to back side of main frame at the drawer opening to span the
cutout section and act as a stop for the drawer face when slide back
into position. Not sure if you can follow that. I'll see if I can find
a link sthat shows a similar configuration.

Table tops have a peculiar need due to the fact that wood absorbs and
expels moisture and this causes the size of the wood to change through
the year. I do suppose India has soime humidity ;^). Wood expands
mostly across the grain. Therefore the attachment of the table top to
the frame must allow for this expansion and contraction or the forces
of nature will dissasemble the table or warp the top. You can see info
on Table Irons, Table Buttons hardware items and there are several
other clever methods that allow for hold down of table tops with hand
made wooden attachmenets or simply using sloted holes with screws,
etc.

Finally, this type of drawer is actually quite common and they
actually sell hardware that allows for the face of the drawer to also
be hinged so it can be folded down after opend to avoid your wrists
being bothered while you type. You could easily make your own springed
hinge.

Found it! Isn't Google great. We live in a wonderful age. Just Googled
"Drawer in Apron" and found this.

This shows a very similar method as I described but they don't have
the additional bridging piece along the face where the apron is cut
away. And, yes you can get away with the apron being split along one
side but be sure the table top has good attachment to the frame to
remove the degree of freedom for the frame to twist.

What you want to do isn't hard to do but *is* hard to explain. I'll try...

1. What you call a "frame", we call an "apron". It provides a place for leg
attachment and is integral to the strength of the table.

2. Make the frame wider (higher); say 3"-6". The normal height of a desk is
28-30" so you should still have ample knee room even using a 6" apron.

3. Make the apron on the side where you want the keyboard tray to be like
this...

c d d c
a _________________________
| b | empty | b |
a ---------------------------------------------

"a" are full length pieces about 1" wide

"b" are as wide as the aprons on the other three sides but not full length.
The two "a" pieces are attached to them

"c" are the side aprons

"d" are two pieces the same size as the end aprons ("c") attached between
the front and back aprons.

4. When this and the other three aprons are attached - *FIRMLY* - to the
legs you will have a cavity with sides to which you can attach a tray for
your keyboard.

5. I assume you plan to make the desktop from solid wood (not plywood). If
so, *DO NOT* attach it rigidly to the aprons...it will tear the table apart
as it expands and contracts.

Solid tops need to be attached so that they can move laterally; usually, one
uses brackets - made or purchased - that are sort of "Z" shaped but with the
vertical part of the "Z" perpendicular rather than angled. The top of the
"Z" is fastened to the underside of the table and the bottom part fits in a
routed groove on the inside of the aprons.

6. I envy your access to teak. Such a nice wood but so expensive here. Not
always so, I remember it at $1.35 per board foot.

Good luck,

dadiOH

In addition to the illustrations: If the keyboard drawer is not full
depth, an additional brace could be run from side to side, directly
behind the drawer for added support.
