Guys and Gals, I will post pics of the upcoming Hopper BTM.  Please be patient with me/us, as this is the prototype and may undergo a few changes.  Please feel free to ask questions.  As, i stated on Iz's post, this kit was very easy to assemble.  I used button-head screws just to see how it looked all put together.  Tonight, I tore it all down and began to counter-sinking all the screws.  
Pieces laid out
