Now that the wing skins are nearly riveted and complete. (I just have the most outboard rib to complete). Its time to start getting them off the stand and into the cart. One of the things that I planned on doing with my wing stand is that it would easily convert into my cart by just cutting a few things off and moving them.
I took a piece of cardboard to take a template for the leading edge shape.
I then used that template (plus 1/2" positive offset) to layout the pattern on the end support structure. The outline is easily cut out using a jig saw.
Of course...I had to pick up these nice big locking castors when I saw them at home depot.
