The stairs going up to the loft were made using 3/4″ boards as treads with cleats supporting them below. One of the cleats had let go and many of the others appeared to be close behind. I knew that I was going to have to do something about them at some point and had been keeping my eye out for used materials. I had found some 2×8’s and 2×10’s that had been used to form up a concrete project down the road from us. They were on the side of the road in the “free zone” so I grabbed them. I used the old stringers as treads and only had to buy a couple of 2×8’s and some construction screws.
