The Avery 1022 AN426 3/32" Pop Rivet Dimpler has bee a very useful tool for a) dimpling holes in areas where the C-Frame dimpler and squeezers cannot get to and b) when rivetting you find the 3/32" rivet head is not quite flush and you need to re-dimple the hole. It uses nails for the pop rivet tool to grab onto - they do eventaully break/pop but spares are cheap from your local DIY. Great bit of kit and like all good ideas - very simple and easy to use.
