I also got the top skin riveted to the rear spar tonight. The new 4″ no hole yoke on the squeezer worked like a charm. I did have to drive the rivets that were next to the doubler plate on the rear spar, as there just wasn’t enough room for even the no-hole yoke. Luckily my tungsten bucking bar had just the right angle to get in there and they all set beautifully!
