A

Cut off 12" from a^5/8" round bar and mark off as shown in the drawing.

Take a NEAR WELDING heat and lay the bar with the punch mark over the rounded edge of anvil.

As this will be a small eye in thick metal, use the ball-peen of the hammer to make the first bend at the shoulder of the eye.

The free end will jerk upwards as described in Lesson 4.

B

Take another NEAR WELDING heat and cool out the bar at the first bend.

Continue turning the eye around the bick-first over the top, then from the underside as in Lesson 4 C.

C

Next trim the end of the eye with a curved hot chisel to form a radius which will fit snugly against the curve of the first bend.

The finished shackle can be seen in the illustration E.

D

With the eye in the bottom swage, close the end of eye down to the first bend by hammering it like this -

The hole should be ^9/16" in diameter when finished.

Next turn the other eye in the opposite direction, but keep them both in alignment on the bar.

E

Bend the middle of bar round the bick to an even semi-circle to form a D, keeping the eyes in alignment as shown in this finished shackle -

The advantage of trimming the ends of the eyes is very plain.

The mushroom-headed pin for this shackle is made in Lesson 19.
