Dan,
I always go to the Vendor's Corner first for my CL needs, but that's me. Including Graphics.
Just so happens we have JD's Foam Wings and John Duncan on the hot wire!
I designed the wing for Pushy Galore and sent John the drawing. Not your normal CL drawing.
PERFECT! He also placed a 1/8" spar EXACTLY where I had it drawn on the plan.
As you said Dan, John sent the wing back and I sheeted it. After the sheeting I sent it
back for removal of the inside core. Again John removed the core EXACTLY per my drawing.
John responds to emails quickly and will talk about your project over the phone.
And his pricing, for the quality product like my custom wing, is more than reasonable.
JD's Foam Wings. In the Vendor's Corner.
Good luck with your project.
Charles
