Still thinking of levering at 90 degrees to the braceing strutts, (surely that must half the pressure) also trying the bracing strutts again at an angle of 90 degrees to the lintel placed at the other side of the upright. No need to take the ropes under the upright, just under the lintel.

Yes, the principle of levering at about 90 degrees to a bracing strut is correct. Any more or less and you start to have to rely on frictional forces to hold it all together and they can be fickle.

My thought with the "brainwave" brace was that the brace and its levers would be partly erected, then the tower would be removed and work on the brace would be completed. The levers automatically reset after each "relax" phase, so you no longer need access to the top of the tower (the levers are operated by ropes).
