Making a Traditional Leadline
Start with a length of 3/4 inch braided cotton twine.
Attach a cast lead weight of 7 or 14 pounds. It's common for
the weight to have a hollow at the bottom end. This hollow
can be "armed" with tallow (Crisco makes an acceptable
substitute) for picking up a sample of the sea bottom.
Mark the line as follows:
|2||2 strips of leather|
|3||3 strips of leather|
|5||white cotton calico|
|7||red woolen bunting|
|10||leather with a round hole in it|
|13||3 strips of leather|
or blue woolen serge
|20||light line with 2 knots|
or leather with two round holes
The marks are designed to be read by feel at night. They should be
inserted through the line and sewn into place. The line should be wet
when measured for the marks.
