There are 3 forming mandrels and a drying rack in the KJI Reed Making System. All the tools are numbered to indicate which is used first and in which order they are to be used. Mandrel #1 is a very slender tool that starts the forming process. The tip is small enough to fit inside the blank without damaging the cane. Other important features are the length, which goes only to the collar / shoulder area without opening up that area and a “Stop” on it to prevent it going too far, making the forming process very consistent.
Moving to Mandrel #2, you will notice that it is a little shorter than Mandrel #1 but it is a little thicker with a steep taper on the end. Again, there is a “Stop” for consistency of forming.
Finally, Mandrel #3 is even shorter but has 3 lines on it. This is the final step in forming. With the KJI GSP Cane you form to the first line only! The other 2 lines are there if you use other cane that is wider in the tube.
Once you are done forming, you place the reed onto the 10-PIN KJI RMS drying board on an exact copy of Mandrel #3 for drying.
