In the music room, our master carpenter begins to install the first pieces of inglenook, while Steve gets a look at the wiring, fuse panels, and emergency backup power unit for the house with electrician Pete Woodbury. Steve continues his painting training with contractor Jim Clark, this time spending a few hours preparing the master bedroom bay windows for final coats. Outside, Roger Cook and arborist Matt Foti decide the fates of an unhealthy ash tree and a split-fork oak is overhanging the east end of the house. Tom shows Steve the system he's using to make mahogany panelling in the music room; one of its key components is a fastening technology that uses plastic ""bow ties"" to hold wood to wood. Our master carpenter and Tom get a lesson in its use from a factory rep.
