Hi guys. Yes I have thought of the Genie lift but the big snag is that I need to get up close to some dwarf walls to place the top beams around the edges, and the balancing arms prevent that. I do have another solution in mind. Will get to that when I start the thread.
Thanks for offers of help. I am making the first three short back posts today. Have a bunch of guys on site laying paving so I keep getting distracted!
