So Tony W worked with Nicky (from S.C.A.R.) at this morning at 9:30 am and tried straightening shelve with horizontal 1" x 2" batons (screwed together at 90 degrees) but the 30x 1" screws wouldn't hold them into the 3/4" (17 mm) MDF shelf. However, having a round vertical post worked well in straightening the shelf so Tony W will combine the two approaches when he tries again tomorrow at 9:30 am :) Also the chain holding the clothes rail will need to be slackened once the shelf has been straightened. Or better still have it supported by the round vertical post instead. The 28 mm diameter circular post is now being painted white and support hole drilling tested before it is installed tomorrow morning.
