I rarely use Surfacing, but I thought it would be the best way to create this part. Maybe I'm wrong. Anyway, I got it to this point, but now I need to thicken it (0.1094") and it's not working. I think it's probably because of the way the curved section meets the flat part, but I don't know how to fix it. I'd appreciate it if someone would have time to take a look at it. And if something that I've done needs to be altered go ahead. The model doesn't need to be exact, just look good in an assembly.
