Okay, that seemed to work but there was not an arrow. It is a video however, so all you need to do is click on the video and it will start. I am going to add about three more below to show progress as the mill progresses down the receiver. When it completed its cycle there will be only about 2 thousands of metal left to file and sand off to be finished. The flat surface of the trigger plate is itself only about 2 thousands too thick. You will see that the mill barely takes the color off it. Most of the metal comes off of the radius where the sides of the receiver meet the trigger plate. I will post more later. It is getting bed time here.-------------Bill
