Could it be done?

My project is currently in the final throes of completion (maybe throes is too strong!), and I too have done frame off restorations and the like, with a lift in my shop and lots of experience doing heavy work alone. Usually alone by necessity, but I do enjoy taking on problems one on one when it comes to "therapeutic" pursuits.
Having said that, I drew the line at some rivets on the wings where structure alignment was of concern, and on the lower middle section where structural strength was a concern. A few other places needed a handful of rivets bucked or shot to save a lot of time.
I am convince you could build one of these completely solo on a deserted island. With enough effort, you could build bucking jigs and fixtures, and do it per plans.
But personally, my opinion is that you'd be missing some of the fun of the build doing it all yourself, but that's not your question.
And by the way, if you have a lift, you'll find it to be one of your favorite tools. Installing the engine, gear legs, tires, moving it onto dollies, and a thousand other options that are way outside the box but make your day.
Substituting pull rivets for solid rivets over much of the areas I mentioned would be a good question for a qualified engineer. And then what you would have is a one of a kind creation that is based on a professional opinion. Worthy of some serious thought first. Hope it works!
