Yeah. I watched that about 4 times.. Mine is different than that, although it looks identical mine doesn’t have that lower shaft on the bottom of the upper shaft. On mine the two shafts are identical, nothing looks like it suppose to turn with a bow, I will post a picture, when I figure out how to. its all brass and looks exactly like the one on u-tube. the one on u-tube has two shafts protruding through base on the left and one shaft protruding through on the right . MINE has just one shaft on left and one shaft on right.
