making the scales in easy but it gets kind of monotonous after a while. first you cut small rectangles out of the larger sheet of metal. i found the best way was to cut 2 inch strips out of the sheets. then i cut the strips in half then the halves in half. and continued doing this until i had a bunch of pieces about 2inches by 1-1/2 inches.
then you cut the pieces in to scale shape hammer out the sharp parts made by the tin snips if there are any. then you poked holes through the corners with the large nails. after this you hammer the hole flat so its not sharp. but this can mess up the hole so then you have to repunctured the scale in the same hole then hammered it again. this gives you a good hole in the scales that shouldn't cut the wire later.
