Max, If you need him, in Horta there is a very good machinist named Ozzie. He lived in the U.S. for a long time - a really good guy. You will need to ask around to find him. There is a auto/heavy equipment/farm equipment dealer a good walk up the hill out of town that knows him - he used to work for them.
IMO, avoid MAYS - Mid Atlantic Yacht Services if you can - there store is OK but their service is poor and overpriced. But they do have (or had) a good book exchange.
