a friend of mine gave me his Ti-10 to fix. the Ti-10 is in overall very good shape, except that the shaft is loose and he is able to wiggle the shaft against the handle. he also told me that the cone has been loose for a while. upon disassembling the handle i realized the reason for the shaft coming out, and that's because of the cone. i took some pictures to illustrate the tight coupling between the handle, cone and shaft and why it is important to reattach the cone when it comes off. the first pictures is to illustrate what the shaft end looks like and how it is secured to the handle. it is basically a graphite shaft with a hole drilled at the end. the handle, as pictured, is wood and has a hole for a screw, the screw goes through the hole in the shaft and ensure that it doesn't fly off. however, most of the strength comes from adhesive that glues the shaft and handle together. as you can see from the picture, after i removed the shaft, some wood fibers were pulled off because of the glue.
