Frames all done

Yesterday after work I was able to finish up the last frame. It goes much better when you understand the instructions...  :)

So far we've put this whole building together with a Bosch 12v Impact Driver. It's not strong enough to tighten the bolts fully, but it does tighten things down plenty tight enough and it's so light and easy to use.  When the building is up, I have to square it up and re-tighten all the bolts anyway with the "turn of the nut" method.

Basically that is really tight PLUS 1/3 turn on the nut.
This actually stretches the bolt slightly and uses the elasticity of the metal to really clamp the mating surfaces together.
