*To cut your reflector from a sheet of anodized aluminum, you will want to first measure the radius of the chair, from the center point to the rim. It is important that the measurement of the radius includes the 3-dimensionality of the curve of the chair. Use this measurement to make triangles with 2 of the sides the length of the radius plus one inch and the 3rd side around 8 inches long. [[Image:PCSC - parabolic sheet.jpg|thumb|right| This shows a material-saving layout for cutting the sections. Note that the triangles don't terminate at a point, so that a 1/4" mounting bolt will fit through it.]]
You may want to measure how many times the 3rd (8") side of the triangle will fit along the circumference of the chair to see how many facets to cut. Since people are going to be sitting on the chair, take care to round any sharp edges to a curve, and to sand any burrs.[[Image:PCSC - shear resized.jpg|thumb|right| Students using a beverly shear to cut aluminum facets.]]
*Once the pieces are cut, gently flex them to fir the curved shape of the chair frame. Aluminum will maintain this shape once bent. First practice bending one to see how breakable it is before bending the rest.
This part of the project is amazingly easy.
*Lay your 3 poles on the ground so that they are lying parallel next to each other. Spread your length of chain so that it too is parallel with the poles and has a few extra inches on one end of the poles. On this end, bundle the poles together so that the chain lies in the middle of all 3 of them. [[Image:PCSC - inner tube tie.jpg|thumb|right| The top part of the tripod. With inner tube and chain.]]
*Cut your bike inner tube so that the circle is opened. Now you can use it for lashing.
