[Heathkit] Fwd: [Hammarlund] Dial Cord Re-Stringing

Fri May 18 10:32:22 EDT 2012

I guess I left too much for the imagination. The last operation in replacing
the dial cord is installing the spring. Put two loops around the end of the
spring where the knot is to be. Hook the spring to the closest fastening
point on the cap pulley' Now pull on the dial cord to get the proper
tension. Now either continue to hold for a few moments or clamp the cord to
maintain tension. Put a drop of cyanoacrylate on the cord wrap at the
spring. Let the glue cure a moment or two. Finish by making the knot adding
a drop of glue and trimming off the excess cord.

You would only use these at the ends to secure the cord.

That way it doesn't get in the way of any pulleys or tuning cap "wheels".
