Macon,
First, Nice Work. :thumbsup:
Second, I have a guess about the sharp line. Could it be the difference in materials of the blocks that caused your sharp line? I wonder if Wicks wood blocks stay straighter than your plastic blocks. Maybe the plastic blocks flex more than the wood and don't keep the pressure as well outside the ends of your vise? Might explain the tip bulge too.
