Building a couple corner computer desks for the SWMBO and I. Plans call for
MDF with laminate on both top and bottom for Tops (American Woodworker,
Oct), but I have 3/4 birch ply on hand and think it might have less sag over
time without the bottom laminate and 2 coats of finish. I've never put
laminate on the bottom of anything I've built and never had a problem, I
put several coats of finish to seal the wood.

So what I'm wondering, over time will MDF or Birch ply sag more? The only
weight on back section will be the monitor, yeah we're still with crt's.
Those lcd flat screens sure look nice, but, I was happy with my Radio Shack
Model I.

I did a few different things on this desk and will post when about finished
on abpw. If anyone else is building this desk I hope you show us what you
are doing.


No experience but I'd have a lot more faith in plywood than MDF.

MDF is flatter, heavier, and it may damp out vibrartions better.
