If you had asked me what a Massironi shelf was, I wouldn’t have been able to tell you until I saw it. When I did see this project, I couldn’t help but think that it looked familiar, but I couldn’t put my finger on why. Perhaps it was in a Movie.
Moving on. This is a very good reproduction of a bookshelf that sells for more than $3,000 today (https://www.pamono.com/vintage-tyco-bookcase-by-manfredo-massironi-1). If you are like me, nothing spurs you on like an expensive project that you can make yourself for MUCH less money.
The Manfredo Massironi reproduction bookcase is a great example.
The full plan along with material list, drawings, and cutting diagram is available at Instructables.com. Enjoy.
