|Here is a the helix with the fascia, valance and backdrop installed and painted.|
The valance presented another problem: How do I get the valance up without support from up above? The solution was to buy small angle brackets and attach short pieces of 1x2 wood to them, then secure them to risers that support the backdrop. I then used left over pieces of curved plywood from helix construction to form the proper radius to match the bottom deck fascia/valance and attached that to the 1x3 angle bracket combo.
|Here we see the curved plywood/angle bracket combo used to form the valance radius.|
Next up was to figure out how to get the black foam-core to bend smoothly. The answer was to lightly score the back of the foam-core at one inch intervals. That created enough flexibility to bend the foam-core smoothly to the desired radius.
|The valance came out good and the curve looks very smooth, no kinks at all.|
Last up was to paint the previously installed vinyl flashing backdrop. I used the same method used on all the other backdrops.

With some black paint for the fascia, and signage installed, the helix will look as good as the rest of the layout. :)
