Favorite Pioneering Knots: Roundturn with Two Half Hitches

Roundturn with Two Half Hitches

The following text is by Adolph E. Peschke as presented in the 1998 printing of the 1993 edition of the Pioneering Merit Badge Pamphlet:

This is one of the basic knots that is very reliable for a number of uses in pioneering work. It is easy to tie and untie and does not reduce the strength of the rope due to sharp turns when under a hard pull.

You start by making a roundturn. This provides extra surface around the spar when chafing or slipping might be a problem. Once you’ve made the roundturn, the rope has a grip on whatever it’s around (see 1). The strain on the rope can then be adjusted before finishing off with two half hitches (see 2 and 3).

The knot is well suited for both ends of a guy line. When it is used in a place where you will not have easy access, as at the top of a tower, secure the running end, (after the two half hitches are tied) with a piece of light cord.

It can be tied in the middle of a long rope by making a long bight with enough rope to make two half hitches after the roundturn.

1, 2, and 3 (below) illustrate the half hitches tied loosely. In actual use both half hitches are pulled up tight.

Tying a Roundturn with Two Half Hitches
  1. To make the knot, start by making a roundturn over a spar.
  2. Next, make a half hitch around the standing part of the rope. Then make another half hitch.
  3. When both half hitches are made, pull them tight, and secure the ends with a small cord.

PIONEERING USES

  • At both ends of large hand and foot ropes for a monkey bridge. Be sure to secure the running ends with a light cord.
  • When wear is a factor when tied to an iron ring.
  • For guy lines because it does not jam, and is easy to untie when adjustments are needed.
