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.
Adjust the height until the height and steps balance out (since you can't have a half or quarter of a step). Take the number of steps and multiply that by 10.5 inches (266.7 mm). That gives you the length of stair stringer necessary. Take that length and project it out from the deck. Now you have the location for the footing of the stair. 3. Lay out the steps on the stringer, using 2 x 12-inch (50 x 304 mm) treated wood, with a framing square. Set the riser for the height determined by your math and the step by 10 inches (250 mm).
