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

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 .....
