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.
This compensates for the tread thickness you install. The top is also squared, with the back of the stringer cut to the length of the run. With the stringers thus laid out and readied, all that remains is to install each and run treads across the steps. Stairs4U: Stringer Layout - Learn How to Design a Stair Stringer.
