Got a few beams in today. Need to set the end one at midpoint then run a string line through to make sure they are all set correctly. Thicker wall plates made from 72x95mm CLS 24 all lettered and pr-edrilled to accept screws. Noggins are 47mm so the difference (25mm) provides the minimum clearance for the beams Telebeam measures 4.4m length. a line was marked at midpiont (between letters 'B' and 'e') Thicker wall plate in place. Had to use angle attchmet on drill due to limited room. Headroom not going to be great but still provides a room.
