1. Learned how to use the special cowl fitting tool I purchased a couple of years ago. Made various measurements of the prop hub and spinner to get an idea of where the spinner backing plate will need to be located, and whether I'll need a spacer/prop extension. 2. Measured, fabricated, and installed the wiring harness for the CHT and EGT sensors. I cut all the leads two feet longer than I think I will need, and used a heat-shrink labeler to mark everything on both ends. I also fabricated and labeled the fuel pressure lead.
