Cord grips installed with this technique are very durable and quite simple to install, I have used this technique for over 10 years and never had the cord unravel or come loose from the blank, but, in a case where the cord may become damaged, or need to be changed, it’s a very simple process as there is no glue or epoxy used to bond the cord to the blank. This method works equally well on thinner blanks that are built up with cork tape prior to applying the cord.
Put the but cap you intend to use on the butt of the blank and mark the blank where the end of the cap will be.
Drill a 1/8 in hole through 1 side of the blank
Push the cord through the blank, out the rear end and tie a knot in cord to keep it from pulling through the hole when pulled tight.
I just put the spool of cord in a small box on the floor to hold the spool.
Wearing a glove because the friction will get things hot, with the blank chucked up in your lathe, pull the cord very tight and start wrapping a few turns. Once you get 4 or 5 turns started you can spin the lathe under power and wrap cord to the end of where the end of your grip will be.
About ¾ of an inch from the end, I use a pull tie just like you would use for wrapping and tying off thread wraps, except I make the pull out of spectra or Dacron. The glove comes in handy here as well so you can pull the end under and tie off without slicing your fingers.
Sealing the cord, I use water based Varathane brand urethane, I strain it first to keep any dried white specks out and with the lathe under power, apply a flood coat to the cord. After the cord is completely coated, put the lathe in dry mode and let turn until the urethane dries clear, about an hour, watch occasionally for bubbles, and if they appear just blow on them and they will disperse. 1 more wet coat and then let dry 4-5 hours
When the cord is dry, cap off the front with a piece of heat shrink and you’ve got a deckhand style grip that will last for years. You can put a turks head at the end, or what I like to do is apply about 3-4 coats of rod finish right on the heat shrink at the same time I’m putting finish on the wrap, and finished product is a very smooth bulbous looking end that looks like a time consuming ramp was shaped
