So I have a carbon shaft blank that is less than perfect. Good news is that the warp seems to be right around 20 in from the tip end. I am thinking trying a travelers cue with it.
Two tough parts.
A. The reverse tapered plug needed at the south end of the first joint. My best guess is basically making a Juma based dry wall expander. Smaller than tap drilled, and cross cut at 120 deg increments. Then forcing a well oiled metal rod into it to get it to expand and glue to the outside walls. Could even cone drill it and use a warm stake to help the forming, and glue if needed. Should be pretty basic afterwords if that works.
B. Materials of both the plug and screw. I am 90% sure I am going to give FR4 a try for the screw just so I know for certain. If it can handle that joint than I never have to worry about it as a real joint screw. Still guessing at the best thread, leaning 5/16-18, but I think the plug material kinda determines this for you to a point.
I initially said Juma above for the plug material as a generic term. Needs to be light weight, but yet handle the stress. I love tomahawk for most uses, but I think thermoplastics are a bit soft laterally for this job, yet most of the canvas phenoloics we tend to use are to heavy. Juma actually seems to be a decent middle ground for a test.
Does anyone have any experience that is relevant here? Or even a good quess that you can support?
