I also found a lot of glazing rabbet modifications.
The only sill that I found to be rotten was this one on the weather side of the building. Pretty good for a 150 year old building that has been painted only twice in its lifetime. But The Dalles only gets about 14 inches of rain a year (Portland gets around 35-40 inches per year).
This is the beam after I cleaned out all the rot.
The D-8 ripping down a salvage beam that Eric donated to the project.
The patch glued and screwed to the existing beam.
The patch hewed down and epoxied.
