LZ, you asked a question about bellcrank offset. You addressed it to Roo, and I don't presume myself to be his equal, or even worthy to sweep his shop floor. But I do have an opinion. I don't think the offset can have anything to do with Akerman, given that you could offset the bellcrank the other way, to the left, necessitating only a longer steering link to keep the bellcrank geometry right so you have equal steering amounts and rates right-to-left. So the right-offset bellcrank allows a shorter steering link to the spindle arms, extremely slightly lighter and extremely slightly more rigid. The biggest effect I can see is that it puts the drag link tucked in really nice and tight to the nose. And maybe keeps a two-piece drag link straighter at the joint for more of the travel. Not much performance reason, but it LOOKS cleaner tight to the nose. But the front drag link could hit the bodywork at the extremes of travel if it were offset too far right.
Or maybe I'm entirely off base. It would be good to see others' comments on your question. If I learned something from that, it wouldn't be the first time...
Thanks,
John Williams
