How to Make The Sling

You will need approximately 84 inches of string total cut into two 42 inch pieces 

Mark the middle of each 42 inch piece 

(Ignore the 20 inch measurement shown - I want to create more room for error with a longer string)

Cut a 5" length of duct tape  and then cut it down the middle long ways.

Place one piece of the tape (the half width of duct tape) at the mid point of both strings keeping a 

1 3/4 inch distance between the strings as shown above.

Fold the tape around the string as shown above making sure to maintain the  1 3/4 inch distance.

Place 2 more pieces (these also are the 1/2 widths of 5" lengths) one inch away from the center on each side keeping your 1 3/4 inch string spacing throughout.

Fold the pieces as shown like you did with the first one.

Cut another 7" length of duct tape and again, half it lengthwise.

Place one of the strips lengthwise underneath the 3 pieces.

Fold the ends over to lock into place

Repeat on the other side to finish the pocket as shown above

Bring the main arm down to the base.

Measure the distance it takes to extend the slings to the back of the base .  

Make sure the sting is tight at the furthest point.

 Tie one side of the finished sling through the hole on the main arm as shown

 Stretch the other end to the release pin at the top of the string arm and tie off

 Once both ends are secure and the pocket of the sling is centered,

you can trim the excess string.
