Ok to make risers I saw a youtube video that said get the total rise and divide that by 7.5. That should give you the number of steps you should have to come down at a good decent. So I did 37 inches / 7.5 and got 4.9999 so I figure 5 steps. Didn't tell me how long just that I need 5 steps. So I'm thinking that the deck itself is a step so that really makes 4 actual steps, but how do you cut that? Go 7.5 inches down the board then make a cross mark to meet that 7.5 down and measure the next step from there? Sounds like a plan if it works.
