Hi I'm going to try the 'two bits of MDF and pole' solution, but have a couple of questions... I need M4 screws, but how are they fitted and what lengths are recommended? How do I arrange the nuts to best (a) protect the guts of the AE100 and (2) allow for adjustment if necessary? Also, what screws are needed to fix the central pole to the MDF, and the top plate to the joist? I assume wood screws, but what sort of size/length. Any other tips for a DIY idiot? Do I need to countersink the screws holding the central pole?
