A

To form the bold shoulder which is required so that the clamp may be driven into the wall, take a NEAR WELDING heat and make a groove with a hand fuller at about 1½" from the end.

B

Using the same heat, draw the end to a fine square point and then flatten it back to the groove to form a shoulder.

The flattened end should look something like a spearhead 3" long with a rib down the middle.

C

Take a DULL RED heat and cut off to the required length.

Holding the flattened end in the tongs take a NEAR WELDING heat and draw to a long chisel point.

Then with the point in the tongs, finish the hook by bending the flattened part over the bick like this -

Test over a 1" bore pipe.
