It really is not going to matter much if you get plate the that is thick. I used 1" as you can see in the video I posted a couple years ago. The critical things to consider is: be sure that the plates are parallel and be sure to keep the pressure even across the material you are pressing. By keeping the material centered the pressure is applied evenly. If you are using multiple dies per press, keep them balanced so the plates stay even when the pressure is being applied. I used a common vinyl cutting board as my base, under the leather. A large one can be found at Sams Club. I think it is roughly 3/4' thick. A restaurant supply store would have a thicker one. This press will drive the die down through the board so be careful.
The biggest challenge is knowing when to stop applying pressure. Also, try not to over think the simple machine. The design in the clicker press I built was based on what I saw that others made and then I improved upon it. Have fun!
