I am brand new to SW and I can barely get it around the patch. I have a friend that is halfway decent with it and he is giving me some dual but, I must admit it is a struggle. Any way, does anybody out there know a way to make flanged lighting holes for a spar shear web? I can make a hole alright but it sure would be nice to put a flange on it. Anyone???Buehler....Buehler....
