Roles

• Pattern layer this person preps the poles for the next stage and helps make sure the pattern is followed
• Nut holder -- this person holds the wing nut with a pair of pliars
• Lifter, 1 or 2, holds the

It is easier to connect pieces at waste height. so pattern layer will loosly get bolt on a step ahead of the snuggers while there is slack, and then the lifters can align and pull things together at waste height, then weight can also go on the new member right away allowing easier lifting.

We order the members so that when we disconnect things the lower ones can come off first. so when we are putting things up the bolt stack is: the ones going to a higher level are closer to the bolt head, and the horizontal ones are closer to the wing nut. then when the next layer gets added

Slack and play is sometimes nice, we go back around and zap the bolts with the impact.

We add tarps before the thing gets too high.
