Diy plans swing set,make a teacher toolbox,dovetail plane kit - For Outdoors
I am not sure what exactly kind of metal brackets you mean -- but you would need ones *expressly designed* for constructing an A-frame swingset. The thing is, in order to make a strong stable swingset you need some rather exact and complex multiple angles where the legs meet each other and the top beam. Whether to make the top beam a 4x4, 4x6, or doubled (or tripled) 2x lumber depends on what forces you're expecting the swingset to withstand, how long the unsupported part of the beam, and what kind of hardware you are intending to use for hanging the swings from.
I realize that does not exactly answer your original request FOR plans but it's some things to think about.
There is not very much keeping it from flexing from end to end (imagine a kid swinging *sideways* on a swing, as kids are wont to do, and the forces that exerts on the frame) - basically just one bolt in tension on each end, which is not a very strong arrangement.
