I have a job that will require me to laminate 2 sheets of 1" MDF together to make a 2" thick sheet. No 2" is available in my area. What is the recommended process and glue to use? Do I need to press it somehow? Can I just suck both sheets down on my Router Vac table after gluing?

From contributor F:
Any good yellow wood glue should work. I would apply it to both pieces using a paint roller with a foam sleeve. You will have to press any way you can, over the entire sheet.
Once placed glue-side to glue-side on a flat horizontal surface, I use ten 5 gallon buckets filled with water sitting on a grid of straightened 2x4's placed on edge across the whole panel surface. Water weighs about 8 lbs. per gallon, so this is about 400lbs of pressure. It's not as much as I would like, but it's always worked well enough.
But for your 2" panels, you don't necessarily need two 1" sheets. You could use two 1/2" sheets with a 1" web-frame in between. I've done this a few times and I really like it. It's stronger, stiffer, and a whole lot lighter. I typically use poplar for the web-frame. Just some ideas.
