Self-tightening ferrules on the Professional and TiCrX Rods
February 3, 2014 Leave a comment
We utilize a specific type of self-tightening ferrule the Professional II series as well as the TiCrX series.
When correctly assembled, there should be about 1/2 -inch of gray blank exposed at the ferrule. Although it looks a little strange, these ferrules are very effective in maintaining a positive fit and preventing lost and broken sections.
This process is very labor intensive and expensive process, which is why it is not utilized by very many rod manufacturers.
During production, the male end of the ferrule is machined to within .0001” of the female section’s ID – and at a very specific angle. You have to make sure you remove precisely the right amount of material to form the ferrule. Removing too much compromises the integrity of the blank. When the process is done correctly, the end result is a ferrule that gets tighter as it undergoes normal wear and tear rather than becoming loose and flying off or causing the rod to fail. The gray area will imperceptibly become smaller and smaller over time, but will never disappear completely. Because these ferrules tighten on their own there is no need to apply ferrule wax or any other material to ensure a tight fit.
