I'll comment on the Eric Newton Manual. It is specifically a series for the scratch builder that Eric created when he was building what we now call the A model. I am building a Patrol kit and it is useful...very useful...even though its for the Model A. I find it very useful for giving you a good order of flow.
I will also say that I think a good order of flow needs to involve the structure that is assembled from the firewall to the aft bulkhead. The fuselage formers, the doors, all windows including the windshield, the wing spar drilling, the struts, the fuel lines, the throttle quadrant on the Patrol....it all somehow might effect other.
Like the formers and fuel line interact to a large degree, so if the formers get installed too tight, it might a hassle, and if the formers are too far out, then will the lower strut bolt go into place. Mine is going in upside down.
So if you can get all that wing root, former, door, boot cowl, gear legs, stick, doors/windows, flap & aileron, flap gap fairing, wing root fairing, fuel sight gage and fuel line stuff set and let those kind of be your guide, i think it might help you see that lots of interaction that will set you up for the fabric cover job. Its not the only way, just one way that might help you proceed, and its what I will do next time.
