I am doing a project that needs to have a wood veneer laminated to a wood substrate. Everything is flat and before I buy a woodworkers vac/laminator I thought my vac/press might work. Any advice? Thanks, Mike

Sure, they both work using the same principle. Just make sure the thickness isn't too great for the press, and I would ease the back edges and corners of the substrate so it is less likely to do damage to the bladder.
I would do a test to see how it works, but see no reason why it shouldn't.

Here's another idea that I've never tried, but it may save your bladder. They make storage bags that are a thickish plastic with a one way valve that allows you to evacuate the air with a vacuum cleaner.

The prob is that unless you are using contact adhesive, you would really need to keep the pressure on
until the glue has fully cured. Which would be at least overnight. A better way might be to sandwich between
two solid boards with release paper and a foam blanket and pile as much weight on top as you can muster.

I've made a vacuum bag out of plastic sheeting from Home Depot. there are several videos showing how.

I've done quite a bit of veneer work and for the most part - I use contact cement and then working from one end to the other - lay the sheet down while pressing out any bubbles. Then apply pressure with a roller. I have only used vacuum bags on surfaces that were not flat. I have never had an issue with veneer lifting after using this method. It also helps with keeping the substrate flat. Flat panels curl pretty easily if using many of the water based adhesives unless you counter balance the back surface.
