A closer shot of the device hole shows a lot of blackened wood
caused from the original iron carriage bolts that were used to install
the device .
The stem was replaced once before in an earlier restoration .
unfortunately ash was used instead of white oak . Ash is a lot easier
to find than white oak , but has little decay resistance .
The nails are removed and the old stem pulled out .
The sternpost is replaced in a similar manner at the same time .
