HOW TO MAKE A
HINGE SCREW
1)
Determine the correct diameter rod needed and thread size.
2)
Hold the rod at an approximate 45? angle to your bench grinder and rotate the
rod in a slow, steady, continuous manner until an even taper is formed in the
rod?s end.
3) Clamp the
rod in a bench vise with tapered end facing straight up about 1? above jaws.
Insert the correct size die
in the die
handle and set the die on the rod?s end.
Apply a drop of Acculube
in the center hole of the die. Grasp the die handle with two hands and position
the handle so that it is perpendicular to the rod. While exerting a fair amount
of downward pressure slowly turn clockwise 1/2 to 1 revolution.
When the die begins to make a good bite into the rod, turn it counterclockwise
just enough to clear away the cut metal (you?ll feel a definite ?break?).
Reverse die direction, carefully threading the die back over the area just
threaded. With downward pressure turn the die another 1/4-1/2 turn and then
reverse direction enough to break away chip. Continue in this manner until the
desired length of thread is cut.
4) Cut off
desired length and cut slot (see our Screw
Slotter) for screwdriver. If desired, a needle file can be
used to square off the shoulder area of the screw.
