Bending is done over the square corners of the anvil if square cornered
bends are desired, or over the horn of the anvil if rounding bends, eyes,
hooks, etc., are wanted.
To bend a ring or eye in the end of a bar, first figure the length of stock
needed by multiplying the diameter of the hole by 31/7, then heat the piece
to a good full red at a point this distance back from the end. Next bend
the iron over at a 90 degree angle (square) at this point. Next, heat the
iron from the bend just made clear to the point and make the eye by laying
the part that was bent square over the horn of the anvil and bending the
extreme tip into part of a circle. Keep pushing the piece farther and
farther over the horn of the anvil, bending it as you go. Do not hammer
directly over the horn of the anvil, but on the side where you are doing
the bending.
To make the outside of a bend square, sharp and full, rather than slightly
rounding, the bent piece must be laid edgewise on the face of the anvil.
That is, after making the bend over the corner of the anvil, lay the piece
on top of the anvil so that its edge and not the flat side rests on the
anvil top. With the work in this position, strike directly against the
corner with the hammer so that the blows come in line, first with one leg
of the work, then the other, and always directly on the corner of the
piece. This operation cannot be performed by laying the work so that one
leg hangs over the anvil's corner.
