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.
I installed the stair treads with 2 deck screws. The treads are 5/4x6 deck boards, which are 5  wide. The pre-cut stringers have a tread dimension of 11 inches, so two deck boards (or 2x6's) fit exactly.But this leaves no tread overhang, or nosing, which is normal on stairs with enclosed risers. Without the nosing, people tend to stub their feet on the riser, and possibly trip. installed the stair treads with 2 deck screws. The treads are 5/4x6 deck boards, which are 5  wide.
