The site that I selected for my Trylon tower was firm enough that I did not
need to make a form for the entire hole. I set some 2x6 lumber around the top
surface of the hole. I attached some form material around the upper edge to
create a smooth finished look to the base that was above ground.
Rather than place the tower on something in the hole I opted to create three
level pads around the outside edge of the hole. I then bolted three lengths of
2x6 lumber to the lower tower section and legs. This gave me three sturdy
mounting points inwhich to suspend the tower into the hole. I then leveled up
the lower section with shims and screwed the whole works together. As stated
earlier take it easy during the pour and all will be fine.
Here is a link to some photos.

How do we put the first section with the level.
I did try to get infos on Trylon site, but found nothing about putting the
first section straight?
Gene's explanation was very good. The only thing plumb on the tower
section is the side of the leg. Drop a plumb line down the middle of the tower
and use it to get things lined up.
You need to support the bottom section w/concrete stub legs either from
the top or the bottom. I typically have the backhoe suspend the bottom
section w/stub legs in the hole and then tie it into the rebar cage. Then I
have a
comealong on each leg and use them to pull it into plumb - and then you're
ready to pour.
I've seen guys sit the bottom section on 2x4's across the top of the
forms. You could make a tripod out of 2x4's and suspend it. I've also seen
various methods of putting something in the hole that the stub legs stand on;
e.g.
building blocks, a first layer of concrete, bricks, etc. The bottom section
with the stub legs attached is 150# plus so you need the backhoe to heft it
around.
