None of my books ever addressed anything more than holding the mallet. No mention of resting the elbow or "chicken wing method." I had to double check just to be sure I had not overlooked it. I have the Craftool Tech Tips, and How to Carve Leather by Al Stohlman. In fact all the stuff I have learned from books has come from books written by Al Stohlman. If I did not learn from those books I learned it from reading posts on this website.
I have used the "chicken wing method" only by accident. I just kinda went with what seemed to work for me. I do, however, believe that it is time to consider buying a better instrument for striking the stamps with. The mallet I have came with a Tandy kit. It works ok, but I would like to see better impressions. I think I will start with replacing the mallet. I am thinking that a 16 ounce should suffice. Still not sure whether I should get the mallet or the maul.
