It does my heart good to see pictures of you down in a pit laying block Eddie, since I am happy it's not me.
I had to make a small set of stairs for the patio I built, and ended up building a form and pouring concrete. I had a certain size blue-stone treads to work with, and a range of desired step/tread height, and it was going to take a lot of block cutting and fiddling to make it work with blocks. I quickly realized it would be faster to design and construct a form and pour it. That said, the form design wasn't easy, just because there were a lot of things to take into account (think about cutting stair stringers and then also compensate for mortar and stone height on steps, and scratch coat, mortar, and veneer thickness on the risers, and of course form size considerations too). It came out OK but I learned many things that would make it a lot better if I ever have to do it again. Actually, if I had to do it again I might let standard block sizes dictate the step rise/run so I could use block, and then get the blue-stone cut to size.
