|File:Beverly Shear.jpg | |2 |Cut out all facets using the Beverly Shear. This process is time consuming as the shear only cuts several inches per slice.
|File:Triangle.jpg ||3 |Drill attachment holes in top corners of all facets. These should be about 1/4 inch in diameter to allow for zip-ties to easily slide through. Drill a half inch hole at the small end of the facet to allow for the anchoring bolt.

|File:Parabolic facets3.jpg | |5 |Slowly fan out facets, being careful not to scratch aluminum. Note: pink protective plastic is left on until all facets are securely in place.

===Maintenance Instructions===
We build our solar cooker with maintenance in mind, our motto was simple construction means simple maintenance. There are very few moving parts on this project making the maintenance a breeze. There main concern for maintenance is proper storage and cleaning. Prior to every use, the polished aluminium faucets must be polished. And without proper storage, the cooker could fall apart in a few years. The main components of the cooker are the zip ties, the chain, and the bamboo rods. All very inexpensive and easy to replace. We have an extra aluminum faucet as well in case of damage to one of the original faucets, and extra zip ties to donate as well.
