Recall the “flat top” design and issues of integrity? The small brace running between the front and center braces allows me to build a flat top instrument (with no top radius). This, and the corresponding brace on the opposite side, will keep the top from “sinking” and maintain integrity! The clamping pressure is handled by use of (2) One, Two, Three blocks and my sine plate – they were never intended for this use, but they did the job!

Next, let’s take a look at the construction of the 15 foot radius dish and the mathematics behind it.
