After taking the R-607PP and R-608PP parts out of the skeleton and deburring, I noticed that they both have undersize edge distances. I think that this is as a result of me trying to get every tiny imperfection out of the edges of these pieces. So I decided to make new copies of them with slightly more edge distance. Part of my reason for getting the edge distance back to 2D was the fact that the R-607PP doubler will have a rivet removed and replaced with a screw for a static bond strap.
