Edward,
Scroll down this site to "Tutorials Techniques and Tips" I have posted a five part tutorial on how I built the whole thing that includes a lot of different ways an methods of how I built this project.
Unfortunately I had to post it in a five part series and you need to read it "from the bottom up"!
Go to "Part 1" first and work your way up hill to "Part 5" for a step by step
But to answer your question....I GLUED IT ON!
