| One of the most secure methods is to make the d-loop from a loop of bow string.(imagine a short bowstring 1 1/2" long wound round two nails in a wood block. Tie the ends securely.Keep the loop open and fold it to look like a letter C. With the bow string horizontal, hang the folded loop over the string so the creases of the fold are on the string and the half loops hanging over each side. (rather like a saddle on a skinny horse) The two halves can be pulled together from below the string so the finished shape can be seen. To keep that shape the d-loop part needs to be served. Tie serving thread to the bow string just below the bottom part of the d-loop. Serve all the strands till you reach the upper end, and finish off by tying it again to the bowstring.
It helps to have the nocking point well placed and sturdy enough to resist any tendency for the loop ends to close in on each other.Serving is easier with a large eyed needle. It can only some off if the string breaks.The serving will show signs of wear long before that happens.
I will try to post pics if you think you want to use the idea.  |
