I am currently trying to construct a corner desk of 24" width 59" on left
side and 100" on the right side. My problem stems in making the top pieces
(22" left section 37" x 37" corner section and 63" right section). I
screwed and glued a 1/2" MDF top to a 3/4" plywood bottom but the results
left an unacceptable warp in the pieces. My question is if I glued a 1/2"
AND 3/4" MDF together could I expect to get a reasonably flat desktop
surface? Secondly, any suggestions as to the method for keeping it flat
during the drying period would be much appreciated.

I'm sure you'll get other ideas on this, but have you considered using
contact cement to join the pieces? Although I wouldn't try using the
water-based type with MDF.

James,
The ply and/or the MDF needs to be secured to a frame that is flat and
strong enough to resist any warping from the ply The 3/4" ply is bowed and
you're expecting the 1/2" MDF to pull it flat - not gonna happen. I don't
know what your frame is like but if you can secure some cross-bracing to it
and then screw the ply down, that should pull the ply flat. I would also
screw the MDF down and countersink the screws. Fill the screw holes with
bondo and then put your (whatever) finish material on.
