[Brion Toss]

Hi,
Great work! Though yes, when I make them this way, I always taper the last few inches of the core, as for a double-braid splice, or to partially decore a furling line. Reduced stress riser, less likelihood of chafe.
Also, the whipping should not be necessary, and might actually worsen things, as core and cover can't shift to share loads.
Fair leads,
Brion Toss
