Having good access to plans as you are building is very important. So important to me, I built a custom plans table. It has wheels, and holds the plans for fast and easy access.
For my RV-9A build, the Van’s plans came in individual sheets, and could be loaded into clear protective sleeves and easy to cycle as needed.
The Sonex plans seem to come in a pad where the sheets are held together so you can flip through them. For the Sonex, I customized the plans table to allow me to clamp the plans tablet edge to the table and flip through them easily. The table is still on wheels and I added a shelf, maybe to hold rivets.
Even when building an all metal airplane, it is a good idea to have wood working tools and some scrap lumber around.
