Step 6: Setting up the airform - only pics

List of Materials

90 degree clamps (to tie down the airform to the concrete)
1/4" - 1-1/4" concrete anchors - 2 boxes  (to tie down the clamps)
2 buckets of sand
roll of cellophane
4 saw horses (inside to keep up the airform)
4 x 8 ft (2x4) (to go top of the sawhorses)

metal jig saw blade(s)
3 - 14' (2x4) to make the connection for the scaffolding
2 x 8' (2x4) to stabilize the 14' triad
2 clamps to tie down the enterance of the airform (with a 2x4)
2 clamps (as for pipes etc.) to tie down the airforms air entrance to the pipe of the inflator
chalk in bright color to mark the openings on the concrete
clamps to tie down the 14' triad to the concrete

List of tools

skill saw
jigsaw - cordless or wired
rotating scaffolding

measurement tape
level
hook iron

Before attaching the airform to the foundation it is important to mark the measurements of all your doors, windows and pipes for utilities. It would be harder to determine this once the airform is up and you have to determine that on the outside. Make your markings inside and mark all the way to the side of the foundation, so it is easily seen once the airform is up.

Determine the exact center by measuring the whole circle twice and finding the line where the measurement is your exact diameter, where these lines intersect is the center. Mark also your walls if you are planning on them.
