Wobble in the HW-19 Jr. Nylon Pulley
Howdy. The nylon pulley on my machine seems to have lost its grip on the metal (motor?) shaft and is wobbling while in rotation. This creates a vibration that can be clearly heard in the signal. I can't find much online for a solution. Any advice?

Good tips here, especially the heat and water trick for nylon pulleys - that worked like a charm for me. These support threads are a great place to trade know-how. In between replies I keep my own routine: a rice purity test sparks conversation among friends online, I grab a random verse for a moment of quiet, and a quick double click test keeps my mouse honest for all this typing. Maintenance days are easier when the workflow stays steady. Appreciate everyone's input on this one!
