So, I got the table legs cut (and rabbet joints in them). Now to attach
the top frame to the legs, how do I make sure that the individual
member of the frame gets attached exactly 90 deg. to the leg?

I mean.. it is hard to hold down the leg and frame and then put a screw
so that they are jointed at 90 deg.... even if they are clamped down...

In general, how is the assembly done? face down? but then once you have
two legs joined to one member of the frame, how do you assemble the
pair.. there is no 3-way 90deg. clamp available..

it is hard to explain in words.. but if you get the gist, how do you
assemble cut parts where one part is laying horizontal on the table and
the other part is to be joined 90 degree vertically, to hold it, square
it and then put to drive a nail or a screw..

i guess it cant be done unless there is another person helping or there
is a horizontal-vertical clamp?

Thanks

I don't know how you made the legs or aprons, but I generally make the
apron as a full frame, and cut a stopped rabbet in the leg that the
apron fits into- or use mortise and tenon joints to connect the apron
directly to the frame. The other way I've seen it done is to stop the
aprons to butt them against the side of the leg, and put in a
45-degree cross brace to connect the aprons. This way usually uses
two bolts protruding from the leg and through the cross brace- if the
leg is not plumb, you can shim one or the other of the bolts with
stack of washers.

As long as everything else is square and properly milled, I've never
had a problem with assembly- the design generally will pull the leg
into alignment, your job is just to hold it as tightly as you can to
make sure the screw pulls it into position rather than out of it. If
you just need something to clamp against, you could try making a false
bottom the size of the apron assembly (or a little larger, depending
on the shape of the legs) to hold the legs apart, and use a band clamp
to hold them in place.

Of course it can be done, I've made dozens of tables. Just pay
attention while you're doing it and don't rush. If your first one
doesn't work out, take a good hard look at it and try and figure out
what went wrong, then make another.

Since no one else has responded, the guy who doesn't build furniture
will give you his best effort. Where I screw up, someone will probably
jump in to correct me (I really do love the way usenet works :-))

I think the "frame" parts are called "aprons". The trick is to mount
the aprons to the (face down) table top with a gap at each corner. On
the inside of each corner you add a diagonal brace with a hole in the
center. Take a moment to visualize this.

Now you can fit the leg into the corner gap and drill a pilot hole
through the corner brace into the inside corner of the leg; and then
pull the leg tight against the apron parts with a lag screw.
Alternatively, you could install an anchor bolt in the pilot hole and
draw the leg tight using a wrench to tighten a nut on the machine
threads.

I like the anchor bolt (wood threads on one end and machine threads on
the other) approach better because it allows for repeated
assembly/disassembly without wearing out threads cut into wood. Anchor
bolts are a bit more expensive but (IMO) worth the added cost.

I wouldn't use nails to assemble a table.

First I make a couple of inverted Us by clamping the legs to the rails. Depends
on construction - if you have a lap at the end you can use an f-clamp, if you
have a traditional mortise and tenon you have to use a sash clamp, lengthwise.

You lean one U against a table, and start fitting the third rail into the
second U, with the end resting in the joint of the first one. Lightly clamp
both sides, then put in the 4th rail. tighten your clamps somewhat, now measure
the diagonals. The diagonals have to be equal, then your table is square. You
can use the same technique to check the legs, but if the joint was cut properly
they should be squaring themselves. You can use a ratchet tiedown to pull the
table square if one diagonal is longer, or a sash clamp - I sometimes bolt two
sash clamps together if I haven't the length.

However, I do not use nails or screws - I use glue. With PVA you have about 20
minutes for this procedure between applying the glue, and fixing things square.
There's nothing stopping you using screws, once you have it assembled like I
described above. I don't see the point myself .....
