I have a Ryobi Detail Sander, model DS1200, the one with the triangle head, and for the life of me...I can't get the sanding pads to stay stuck on the head. I've tried different pads, as in Diablo and Ryobi, but nothing seems to work. This is extremely frustrating. I watched a video where a guy used a hot glue gun to keep his pads on, but I was wondering if any of you have had this problem and what you did to resolve it?
