Step 1: Materials and tools
I needed one 1/4 20 bolt to attach it to the tripod mount.
I used an angle grinder with a zip disk, I used about 4 clamps, a drill and a hammer and center punch. I also used a small sheet metal bender but this could be done with a vice if you don't have one.
I also used the 3d cad program called solidworks to help me design the shield. If you don't have or know this program there is google sketchup which I hear is good, easy and free. This could also be figured out with a tape measure and a piece of cardboard.
Step 2: Design
Step 3: The Build
Step 4: The Installation
The whole project from start to finish took about 15 minutes and cost nothing because I had the stuff lying around.
I also made a video for my friends podcast of this build.
