I was having a problem figuring out how to layout the slots for the seat belts on the seat pan. One guy from the forum came up with the idea to draw radial arcs from the starting point of the two location measurements from the drawing and then find the point where the length of the slot intersected the two arcs. Gave that go and it got me a location that looked right - so I went with it. Got the slots cut and smoothed so they are done and ready for seat belts when the seat is finally installed. I also Hysol'd the right window frame so that tomorrow I can permanently install the right side stringer.
