Shit can the laminate. You building a suzy home maker or full tilt reloading bench? Hence C Clamping the press until you see what works best for you.
For the 3rd press i cut a small piece of wood and drilled the mount holes in it. To secure it to the wood i used 7/16 t-nuts secured on the bottom. This allowed me to bolt / mount the press using C-Clamps, with the option of removal when not in use.

Measure once cut twice;)
If you are hung up on the whole process there's the Reloading forum where you'll get lots of good ideas and direction, Plus look at pics of our benches.
