I live in a 78 year old home in Los Angeles. The living room floor is supported at the perimeter with a stem wall foundation and on the interior by a series of beams supported by posts on top of poured in place concrete piers. The “posts†are really 2 rough 2×4’s  (2inches x 4 inches)  scabbed together and  toenailed to the rough 4×6 beam (4 inches x 6 inches) The “posts†simply sit on the concrete pad which is not even in line the beam. I’ll be replacing each post and concrete pier. On the bottom to connect the post to the pier, I’ll use a Simpson 4×4 column base imbedded in a new cast in place pier. Then a 4×4 post (3½ inches x 3½ inches). Then a Simpson post cap (probably the AC4) to connect the post to the existing rough 4×6 beam. The post is ½ inch less than the beam it sits under. An architect acquaintance suggested purchasing a 4×6 beam (3½ inches x 5½ inches) and reducing it down to so it will measure 3 ½ inches x 4 inches on the top portion and 3½ inches x 3½ inches on the bottom portion. This way I’ll achieve a fit in both connectors and match up to the beam. The easiest way to accomplish this would be with a band saw, which I don’t have and have no access to. Is there any other way to do this? I’ve got a table saw, skill saw, a portable planer, belt sander etc.
