This design is the same as the Flickenger design except for two variations.

1. I spaced the washers 1.21" from center of washer to next center of washer. This makes the whole director assembly 4.84" long.
2. Instead of using cut tubing and all-thread, I used 7/32" aluminum tube which exactly fit the inside diameter of the washers. I slid the washers into place and superglued them in place.
