Tight Access vs. Big Hands

In my previous post, I mentioned the tight access through the lightning hole while riveting the leading edge ribs to the spar. It got me thinking last night about limited access in general. I'm hoping that that was the worst of it although I still have the right wing to go. The picture below shows what I had to do to get my hand through the lightning hole. I'm not complaining about this minor scrape (or the matching one on my thumb) as that's to be expected when working with machines. I am worried that if there are any access openings just slightly smaller my hands will never fit.
