Very nice job, love the brass washers on the outside. I had the same problem on a couple of blades wanting to pop out of the scales due to the tang & I ended up putting in a third pin. The third pin spacer opened up the scales up so that the scales aren't squeezing the tang. If you do it, just pay particular attention to placement: Monkey tail swing on opening & how deep the tang sits (or you want it to set) in the scales.
