I have to admit, I am still impressed with the scale of your project.
I do have some concerns, however. I do not want to discourage you! Quite the opposite; I admire your ambition. I want to see you succeed safely. So please accept my humble suggestions:
Some welds in recent pictures appear to be rushed and contaminated. They will be vulnerable to fatigue because vibrations are expected in a VAWT. I recommend that once you have completely fit all of the parts on the axle, and balanced the blades, that you completely disassemble the entire turbine for a thorough inspection. Grind/reweld where necessary, thoroughly clean all parts, and then paint everything so that it will last much longer. I understand that this will delay the completion of your project for a long time, but I'm certain that this will improve your chances for success and make your turbine last much longer.
The bearings should be sealed. While the slinger covers are a very good feature, they aren't enough to keep dust out of the bearings, which will wear them out very quickly.
The diagonal braces have a "zig-zag" in the middle which, while I think I understand why you flipped the truss half-way, does not connect the halves together well.
The tower is strong and sturdy but still probably overloaded by the wind turbine. I agree with Mary B's suggestion to use many guy wires, but the total mass may still overcome the strength of the tower itself. In fact, tightening the guy wires will add compression force to the tower, making the situation even worse. Has this been checked by analysis?
Raising this tower safely may also present a challenge: the crane hook on the top of your axle is not strong enough for a safe crane lift.
I also hope you and the people that are helping always keep safety in mind at all times. Now that the machine is assembled, it can become a dangerous time. With the blades installed, the machine will turn in the wind and requires a brake all the time. People become so eager to get the project finished that the urge to hurry can be unbearable. Resist the temptation, and double-check every step.
I see climbing pegs on the axle. This implies that you expect to climb the tower and the VAWT while it is raised up. Are you prepared to stake your life on the braking system?
I feel compelled to ask these questions because I have experience in these matters and I want to see you succeed.
You are under no obligation to answer me, but I hope they are considered and dealt with before you proceed.
