Lately my Vandy 215 oscillator has a shudder as it travels back and forth. It actually seems to be stocking to the inked up rubber rollers below. I was able to stop the chatter by adding a small piece of lead between the metal roller assembly and the bearing block of the rubber rollers (see video and photo). I’m beginning to wonder if my motor may be at fault, if it perhaps doe not have enough power to keep the rollers from “sticking” to the rubber rollers, when they have ink on them. I have added a video with the sound, as well as a photo showing the “solution” which is not really a solution, as it affect even inking.
