I cut backing to about 3/4" larger than the frame, and then use small 'wedge' paper clamps (buy them cheap at Staples) to hold the backing in place-once you have everything aligned and squared up, reach underneath and take the clamp off. For material that wants to move around-slippery nylon or something, I have the 2" wide wedge clamps that I bent the wings down-so I can clamp the 'frame' itself together, and the wings pointing down so they won't catch the trimmer bar or needle head. As Rod said, always, always make sure the clamp handle is SNAPPED down into place-you have to FEEL it go into locked position. AND to prevent damage next time you start it up, remove the frame and top frame when done for the day. =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
