Base & Plenums Concept

 
Basic Structure

Above is a sketch of the core build, which I already have materials for and the main plenums have already been bent into shape. The poorer hardware has been mocked up for a single plenum and tested, too... much to the surprise of my neighbors :)

The components for this part of the Crystal Heart are the same as a standard poofer.

• Schedule 80 black pipe
• High pressure, default Closed solenoid (12v)
• Accumulator tank 
• Regulator to feed the accumulator (~100 psi expected)
• Branch & regulator for low-pressure feed (~20 psi expected)

Note that I may experiment with a separate set of lines directly from the tank to the plenums for the low-pressure feed to reduce the number of regulators (easier tuning of pressure). The accumulator out would tee into this just before flowing up through the base.

Sculpture Base

For the base, the plan is to use a massive steel wheel from an old steam roller, filled with concrete. That will be modified to allow a central tube for plumbing the propane and electrical. Also, rectangular horizontal holes will be cut for a forklift to easily slide through the base and move the sculpture on/off a flatbed trailer in a simple act.
