DIY Screen Stretcher (My Idea)

Working on a set of plans for my DIY Screen stretcher. I will be able to place the frame in the middle, place the screen between the front sets of 2" x 2" blocks that get screwed together (keeping the screen tight between them) and with the outside 2" x 2" strips that are fixed to the particle board I will be able to tighten the bolts on the outside to pull the screen tight in each direction. At which point I will be able to glue the screen to the frame and trim off the access material.
Here is the idea that I have. Please provide feedback as it is truly appreciated. (plans are just a rough draft.)
