Silly question that I have never really thought about...

when You are epoxying two pieces together....I'll using laminating in my example...
How much pressure do you use?

just set them (the peices) together and leave it?

a little pressure ( a light weight or something) just to make sure the pieces don't move...?

or do you calmp the heck out of them?

assume that the peices fit together just about perfectly and I am using 30 Minute epoxy....

I just haven't really every thought about it before and curious what others do....

Cheers
