Thank you Robert
With the lower skin dry, decided to put some vertical braces in. Wendell uses this pocket for a wood plug that is a wooden wing tube.
Since I don't need that space, thought it prudent to bulk up the 1/16 ac ply skins where there is a wing rib.
I left the ends open cause I intend to us a plug to align center and outer wing halves during construction.
Once this is all set up. I will run a flushing router around the template. Cleans the hard epoxy line very clean.
Then it gets separated from the template and the template gets saved (least another gets built in the future).
