And a couple more. The aluminum stand-offs are a standard item from McMasterCarr. They are 3/8"x 1 1/2" hex style, with 8-32 threads in both ends. I intend to turn these down some to further reduce weight. They add more than 1 1/4 ounces (about 36 grams) to the mount and I am certain I can get the weight to about 20 grams. Even at the current weight, the mount is not exactly heavy (3.8 ozs). The standoffs cost about $1.40 each...but there are shipping charges as well. I believe that 1/2" square maple stock would work fine in a soft set-up like this, and that would save an ounce probably
