Anyone who is wishing to shoot a style of archery that uses the so-called 'Mongolian Draw' needs to have a thumb ring. While most traditional thumb rings are made of horn, others are made from metal, stone, or plastic. We will work on the plastic type in this article.
The procedures in this article are somewhat simplified, so there are two basic assumptions that are made: you have at least a basic knowledge of how to use the below-mentioned tools and you are able to extrapolate from the information given.
At the apex of the ring, a small dip should be inserted, with a shallow channel and a cross-secting ridge. The reason for this is that the string needs to rest next to your thumb, otherwise it might slip.
File away, until you have reached the desired size and shape. Upon completion of that, take the sandpaper and water and sand the thumb ring smooth.
Mr. Shim was able to do the entire procedure in about two hours.
