x2 nice write up, bud.

couple of observations -- if you wanted, you could make more shavings of the abs plastic, and mix it with ammounts of ABS cement to make 'liquid abs plastic' that will melt in with the surrounding area, making the patch part of the rest again, negating the jb weld.

second... that's still too much work for me -- i have a mount from humount.com Mark's a good guy to work with, and the product is good, too.
