Yesterday I realized that I had made an error in my planning of the block walls. I did not account for the 7-degree batter angle on the face of the blocks. In other words, each course of blocks as you move vertically steps back 19mm (roughly 3/4"). At a corner the step occurs in both directions. This complicated the planning considerably. My initial plan only required a single cut on one of the caps, but now I'm going to have to make 28 field cuts and the aforementioned single cap cut. Not the end of the world, but a definite complication. The other problem is that my block quantity estimate is now just a little light. I'm off by about 16 blocks with no room for error. Assuming I'll cut a block or two a little short and have to redo the cut with another I'll likely need about 25 more blocks to be safe. They come in three different sizes which further complicates things. Not a worry as I needed them to come back out to delivery another 4-6 yards of crushed rock and pick up all the extras and palettes.
As for the cutting; I can't find a place to rent a block saw that will do a 6" thick block. The sliding table-mounted saws I can find to rent all stop at 5". Fortunately they can make a straight cut that's 17" long and all of mine will stop at 12". What that means is that I'll have to make a full length cut, then flip the block over and cut out the remaining 1" section. Not a big deal, but it does turn my 27 field cuts into 54 (the one cap is only 3" thick and won't require a second cut).
Here's the saw I'll likely be renting for the job, the trusty Norton BBM307:
Lastly, here are a couple of renderings I did in Sketchup of the completed block wall with a mockup of the 14'x24' studio structure sitting on top of it. The center will be filled with clean fill dirt, and then the top 6" will be compacted 1/4"-minus crushed rock.

I'll be constructing a second structure that attaches to the back of the building next year. It will be a sort of "car port" type construction (i.e. posts and trusses supporting a roof with no walls) as a cover for our cedar, infrared sauna, as well as our the hot tub and cold plunge we'll be picking up. I'll be doing the ground cover with concrete pavers and fencing in two of the three exposed sides to match the fence around the front of my house. I'll also be adding some privacy screening that can roll down the fence for when we're using it. Can't have the neighbors bumming our soak! Lastly a row of arborvitae plants will continue down the alley to complete the process of closing off our property to the alley and the adjacent properties. Projects as a home owner simply never end.
