I am a graduate student at Ohio University, having issues with our Vandercook 223. Serial no. 8160. I do not have the vocabulary to accurately describe the parts of the press involved, so I have included several videos and pictures to illustrate.
As the cylinder gets to the end of the
track – where the registration clamps [gripper bar] disengage [releases]e – it becomes very difficult to move it forward. After the registration clamps [gripper bar] disengage [releases], it moves smoothly, but has the same problem on the return. This problem arose during normal use. Over the course of 2-3 prints, it became increasingly difficult to move past this point. I have checked the track/ gears thoroughly for any obstruction.
One issue which may be related is some slack in the handle/chain inside of the cylinder. I have included a video of this.
Any input would be greatly appreciated! Thanks!
