I went up and worked some more on that clamp section. After jointing, planing etc. to get it looking good, I realized all I did was waste a $60 piece of wood. The width is fine but the height is 1/8" shy of what I need.
The curve is correct as shown below.
The two pieces match up nicely.
Ah well, practice makes perfect... I think I'll cut all dimension a bit over so I can plane it out nice and slick without coming up short somewhere.
We did get a couple of the foredeck beams done....
...so it wasn't a total waste.
I suppose I'll snag another board from Targo Wood tomorrow and start again.
