Cowling

More Fitting of the Top & Bottom Cowl Sections

Okay, so after coming this far, I have the cowl halves fitting together, the front end fairly flat, nesting together properly, looking pretty good, and I'm very anxious to give it a trial fit on the airplane. But I still can't put the lower cowl on the plane. Why not? Well, there's still more to do before that can be done. The RV-7A has a nose wheel, of course. So the lower cowl has to have a slot cut in it, so it can slip on over the nose gear leg. Taildraggers have the main wheels forward of the firewall, so they have to be trimmed, too. So today I started on that task.

As I got out my tools and started measuring to mark the slot to be cut, I realized there's really no good way to figure this out. Where's the center of this thing? There's really no reference point here, it's all curves. And will the gear leg be in the exact center anyway, even if I could figure it out? There won't be any good way to figure it or measure it. You just have to hope for the best and cut a slot. Hopefully, I'll get it right.

So I found the center as best as I could estimate, and cut a hole. The extended lines I marked on here will be cut next.

I've already been working on this for a long time now, and I still haven't seen the lower cowl on the airplane. Hopefully it won't be much longer now.
