Cut the Base Frame from Pressure-treated Two-by-foursMeasure and cut all the pieces for the base frame from pressure-treated two-by-fours, because it will rest on the ground exposed to insects and moisture. Working with the dimensions on your plan, cut two long and two short components for the outer frame, and two slightly shorter stringers for interior bracing. We use a sliding compound miter saw, but a chop saw will do a good job on these straight cuts.
