Forum Title: Calculating Angles Assistance Requested.
I have been tasked with demolishing and rebuilding a significant set of steps. The existing had a very expensive Bronze railing that will be reinstalled, modification of the railing is pretty much out of the question. I have taken pretty good measurements of the existing conditions, have demoed the existing steps and retaining wall and have formed the footing for the new installation. I am good with the footing we have formed, as it only needs to be -2' from the finish elevation of the new retaining wall and have the correct changes in elevation, that will match the old installation. My problem is creeping up on me, in that to complete the wall I will be forming a 12 thick wall on the footing and the breaking point of the change in angle must be directly vertical to the point of change in the footing. I realize this is a fairly elementary question for the seasoned carpenter, but what is the best/quickest way to determine the angle at which the form must be cut to assure the change of direction is in the proper location and the form is as tight as possible. We will need to strip and finish this as the concrete is poured, so the closer I can be the less hassle finishing will be. See attached photos for some idea of what I have gotten myself into... Thanks!
