This afternoon I cut the F-holes on the Sinister. I stamped locator pits in the waste area with a small centre punch. The drilling went well, with no drill wander. Using a sharp knife ground to a thin profile, I then cut out the waste along the holes, then cleaned up the edges. It went pretty well, but I had to glue the bottom points where they split from the body during the trimming. The edges still need to be sanded smooth.
I trimmed and sanded the remaining cleats. The insides are now all clean and ready for assembly.
