we were lucky I had a 15cm piece of Kialoa shaft that fitted inside this one so we tapered the ends of it to try and minimize the inevitable stress risers we are creating
before and after wrapping , the before shot shows the glass/carbon layering of the broken shaft , and the after shot shows the simple masking tape used for compression
Do you taper the thickness of wrap from the centre of repair out? That is thinner further from the break?
the fabric wrap is replacing what was broken , and the inner sleeve was "beveled" on the ends to minimize that abrupt change (stress riser)
