I bought a “Center-It” jig a while back, so I pulled that out for drilling the bellcrank-to-aileron push tubes (the smaller ones). The dimensions aren’t called out on the drawing. It’s a full-scale drawing, so I just measured off the drawing. I drilled both ends of one of the rods. It turned out pretty good. The drill had a tendency to walk a bit on the powdered coated smooth, round surface. I’ll probably try using a punch on the other rod to get the holes placed more accurately.
I know some people weld the ends on these rods. It seems like a weak point to have two rivets holding it together. I can always order replacement rod stock and ends if I decide to get these welded. For now, I’ll use what hundreds of other RV’s are flying with.
