While building an RV-9A I built a stand to hold the plans while I worked.
For the Sonex, The plans come in a different format. They are a “pad” of plans stapled together into a very thick stack. By lowering the plans surface and clamping the plans to the top, we have a very workable arrangement.
The plans are tough and can be opened and close many times without wear.
So, I modified my Van’s stand to be a Sonex stand and I’m very happy!
By changing from an upright stand to a lay down stand, and clamping the Sonex pad to the desktop, I’m able to flip through and page quickly and easily.
With the Sonex plans, you work on a page at a time anyway. No loss.
