An extra set of hands
I havent had any, so I built one. That is a bracket made from ipe scraps that I clamped on the deck at the end of my fascia while I screwed the other side in place. Because I could slide the fascia in the bracket, it allowed me to adjust where the mitered ends met; I had tried just clamping the fascia right into place, but it was impossible to get the ends to meet precisely:
Heres the deck with all the fascia in place:
The odd colors here are just shadows as the sun set on a wonderful 75-degree day in the middle of November:
