Before posting my weekend update, I wanted to give a HUGE thanks to Mr. Tim for helping me out. I was really struggling with the design for the curve on the face of my riser. I just wasn't happy with anything I was coming up with. He helped me out by modeling a few different measurements for me so I could quickly mock up and test some of my ideas. With that said, I think I finally have a winner!
I had a lot going on this weekend, but I was able to sneak into the basement for a while both yesterday and today. I made some really good progress. The best part was finishing the curve and steps on the face of the riser. I finally found a design that doesn't stick way out into the room, but allows me to have a curved step coming off the front of the riser. I really like the way it turned out. It isn't easy to see in the pictures, but the curve on the steps follows the curve on the riser face.
I do have one question. The plywood that I used for the face of the riser steps was a leftover piece from some of the other curves. The two step faces are between 1/8" and 1/4" shorter than the 2x4 supports used for the step. Should I just cut new step faces that are the full height, or will this small gap not make a difference once the tread is put on? I just don't want to cause issues with the carpet install.
The other item that I decided to tackle today was putting the sand in the stage. I started by cutting up a roll of 6 mil plastic. My original plan was to put two bags of sand into each cavity and let them dry for a couple of days before adding a couple more bags. Fortunately, the sand I bought was bone dry and the extra drying time is not needed. So far I have 4 bags of sand in each cavity. I am now working my way back through and using a 8"x8" piece of plywood and a 4 lb hand sledge to tamp down the sand. I'm not really hitting the plywood, but just dropping the sledge onto the board to compact the sand. I am then going to go back through to trim the plastic and top off the sand.
I feel like I am finally making some progress with the stage and riser. Hopefully this week I will have time to put in more sand. I also want to finish my planning for any wiring that will go into the riser.
I have several rolls of R19 insulation left over from the ceiling in the other part of the basement. Will that be OK for the riser, or do I want something thicker/higher R value?
