I am finishing up on building a pair of AV-3's,but have a question regarding the best method for attaching the griil cloth to the grill frame. Normally I just staple the grill cloth to the back of the grill frame;however,since the AV-3 frame is rather thin at the top and bottom I don't think stapling would be the best method to use. I have also used 3M Super 77 spray adhesive in the past,but found that it has a tendency to loose its adhesiveness over a period of time allowing the cloth to start pulling away from the frame. Does anyone have any recommendations as to other attachment methods that might work better?
