I did not use the vacuum press on this project, because I wanted to show that you can accomplish not only the bending of the curved sides with the Curvomatic, but also the application of the veneer, and that you can both curve and veneer in a single step. I thought that might be important for anyone trying to decide if the Curvomatic is really worth the investment.
Just to clarify a bit, I curved the first two sides without veneer, just to get a feel for using the Curvomatic, then I curved and veneered in a single step for the second two sides. After that, I veneered the first two sides with the Curvomatic.
For veneering the tops, bottoms and backs, I clamped the cabs together, so each acted as a clamping caul for the other--top to top, bottom to bottom and back to back. A piece of 1/4" MDF separated the cabs and waxed paper acted as a barrier for glue seepage.
