This process was a nightmare. It's been so fucking hot here that I didnt even want to be out there. I was pretty happy with everything and then wifey asked me to fix it and make the treads wider. I was gutted, but I did it anyway. I went back to lowes and picked up 4 more 2x12x12s which are HEAVY. These things are solid. It's the first thing that my circular saw, well after I learned to use it, struggled cutting. A couple of pauses but we pushed through.
