Now I had a repeatable process, I worked past sundown to finish enough components for all five trusses
On the next set of cuts I tried a different strategy. I put two boards on top of each other and set my cut depth to the thickness of the board plus a small amount. This left a "line" to cut along for the next pair of boards. This particular cut wasn't as easy to use a saw guide and was much shorter to let me more easily made freehand.
There were ten trusses, I worked on the last four as a group, some boards had two cuts, so this cut had to be repeated sixteen times. Having a repeatable process helped me be more consistent.
