For anyone without these gauges the magic number is 18. Normally steps rise about 7 inches or so however this could be different based on the overall height of the stairs,so you take your overall height and divide it by 18 inches and that will give you the number of steps in the staircase.heres where 18 comes in again if your step is 7 inches tall it will have a 11 inch wide step if its 7.5 inches tall it will have a 10.5 inch step so you move up the board 18 inches per each "triangle" until your runners are made.
You don't divide the total rise by 18 unless you're certain you want 18 risers- 😂. You divide the total rise by 7.5 to get you in the ballpark for the # of risers, and THEN adjust that up or down based on the space available.for the stair. The "18" rule is fine for determining the ideal riser/tread combo but it is not always possible.
OK, I know about stringer guides. I was looking forward tutorial not a commercial. This kind of glazes over the process which needs to be done very carefully, including calculating the rise and run and not getting Inch and a halfed on the last riser
Brass stair guages from the lumber yard for $5 work just as good. All these construction videos pushing over priced tools. Yeah they cool but $40 for a pair of dogs is rediculous!
Bro is it me or does that look like an awkward ass stringer? That tread is not no 12” by 7” rise and I know it just has to be close to those dimensions but Jesus that’s not close at all
