In total, about probably 15, 20 minutes. I made the figure right before I posted, heh, so it didn't take too long. And actually the conversion part (drilling the hole in the hand, repostioning the hand, and attaching the speartip) was quicker than cleaning the mold lines off the other parts.
And yeah, my goal with this unit is for it to stand out, even though they are just statetroops.
