I have no issues on the other arm. How could I resolve this? I even soaked it on a cup of lub to loosen but to no avail. I don't want to take the ball out for I might damage the delrin arm.
I emailed exotek about this. Haven't got a reply yet. TIA.
I just finished building the Exotek 104, I had the same problem with ONE of the front upper arms. One fit perfect and the other was TOO TIGHT. I used the metal pivot balls so I couldn't sand them so I took a BALL SHAPED dremel head and removed some of the material from the inside of the arm where the ball seats. It is important to take a little bit at a time and try the ball, then take a LITTLE more and try again. It took five or six times to get it to a acceptable fit.....Remember you CANT put the material back on so take your time....
