RE: AR-6 Wing mold construction
Now that the part board is roughed out, I've started to lay in the "rest" for the leading and trailing edges to sit on.. This accomplished 2 things.. First, it helps keep the center line consistent the full length of the parting board.. Second, it will give the bondo a place to sit until it hardens when I seal the plug to the parting board.. Which it turns out, is the next step.
