I am in the process of tearing down an old pool deck. The frame is connected using plates that have 4, 3 inch nails on each side. I am trying to salvage the lumber as it is still in great condition and I would like to save it for future projects. My question is would it be practial/quicker to use a Reciprocating Saw or angle grinder (or something else) to cut the plates at the seams? I tried using a pry bar but I was damaging the wood and it was impossible to use it in the corners. I'd say the metal plates are roughly 1/10 inch thick. Any help would be great.
