Useful tools include a adjustable reamer (set to 27.2) and a old seat post to check. A motorbike cylinder hone and drill. some rotary wire brushes. some strips of emery cloth, sand ceramic plumber tape. some Dremmel sanding wheels and a bottom bracket tap and a headtube reamer. so time to ream the head tube and bottom bracket:
