Build Note: Hold the turnbuckle stationary

with pliers and push the rod end hard onto the

turnbuckle while turning at the same time.

Keep in mind that one end of the turnbuckle has

normal threads and the other has reverse threads.

Start the rod end straight and it will thread on straight.

Build Tip: Use some grease or Chapstick

on the threads to help prevent “pop-o” when

adjustments are being made.
