You are absolutely right Alan, the shrink fitting method is used to fix the round pesi into the round ganja hole - and according to my teacher, it is the old tradition (what ever that means...)
Although i dont have any sundang that was made by my teacher, I was told by him that is the only way for him to attach the ganja to the blade, be it on a keris or sundang.
And, your question about how the ganja is kept in place - would not it be securely kept in place when the ganja is mounted to the pesi when its tightly cold shrunk? Some of my kerises were made by my teacher, and the ganja were fitted this way... I have never experienced the ganja of my kerises loosen even after soaking them in citric acid solution, as compared to using glue or epoxy.....
Maybe I have not answered your question, if so, please rephrase it again as English is my third language after Malay and Javanese
