vacuum bagin works very well in this application. you get very uniform
clamping pressure with a vacuum bag, and do not need extra boards to
distribute the load, like with clamps. Like the other poster said, just make
sure you have it supported flat when you glue it up. Assuming you get 10
inches of mecury vacuum pressure (which is real easy to do near sea level,
even with an old worn out vacuum pump), you will be applying over 12,000 lb
total force to your glueup. It is hard to match that with weight.

I have used Titebond in this application, and it worked well. If possilbe
tack two corners together with a small brad to keep the baords from shifting
while you apply the bag.

What is the best way to glue together ( laminate ) 2 sheets of MDF
together?
The size will be about 13" X 96". What is the best glue for the job?
Would vacuum bagging work well? TIA
