I am trying to countersink the VS-702 for the VS-01401 doubler. The problem I am having is I cannot get the sink deep enough before the hole enlarges. What am I doing wrong? I have already reordered the VS-702 as the first countersink enlarged the pilot hole and then wobbled badly. I then tried countersinking with the deburring tool. With the rivet still sitting just proud of the surface the hole is already starting to enlarge.
Not a fantastic start to the project.
