Answer: Your vinegar should be fine, provided youâve been storing it properly. From a safety standpoint, commercially produced vinegar has a virtually indefinite shelf life, says the Vinegar Institute, an association that represents most of the worldâs largest vinegar manufacturers.nd itâs not unusual for vinegar to develop a haze or sediment, or to change color, after it has been stored for some time, says the Institute. Those changes in appearance do not make the vinegar unsafe to use, it adds.
The following analysis demonstrates results of a typical wood-framed stair stringer configuration as well as several similar configurations. Consider 15 risers at 7Â¼-inch tall with 10Â½-inch wide treads and stringers cut from SPF No. 1/No. 2 2x12s. This configuration results in an effective throat depth of approximately 5 inches for a horizontal span of 12 feet and 3 inches.
Convert stair layout to stringer cutting layout: Draw a line to connect all the points on the stair stringers. Note that this is parallel to the nose line of the finished stairs, but is not the same as the nose line. Make another line parallel to the first line, 11.25 inches apart. This denotes the width of a 2x12, the standard material used for stair stringers. In the drawing below, note some interesting patterns:
