A

Approximately 18" of 1^1/8" x ^1/2" bar is used for the harrow draught hook.

Bring one end, which will form the hook, to a NEAR WELDING heat.

Drawing down should be started on the anvil bick and finished off on the anvil face. The diamond head is formed as described in Lesson 16.

B

In forming the hook, the first bend is made on the top of the anvil bick as shown in Lesson 2.

A harrow needs one righthanded and one left-handed hook. So, at the second stage of bending shown here, the point of one hook is turned to right and the point of the other hook to the left of the bar.

C

One completed hook - for a diamond harrow frame should look like this -

The other should have the hook bent in the opposite direction, as shown in the drawing.
