I forgot to say, in my earlier post, about how I handle rails that do not just bend around a corner. Say a rail ends in a ladder-way. No new section at right angles, but it is well less than a full section to the end. In that case, many times I can cut the bottom and intermediate railings to the proper height, and cut the top one very long. Then I bend that top railing down at 90 degrees, making the post from the top railing.
