Hey Guys,
I am getting further into my Boss retrofit, and noticed my Z-Axis pulley looked much different than the X & Y axes. I think this is a hack-job by the previous owner. The teeth actually look like they were machined, instead of cast like the others. Take a look at the photos and see if they look anything like your Z-Axis pulley. If yours is different than the photos, perhaps you could share a photo of yours??
Forgot to mention......the entire pulley is aluminum with the exception of the thin steel ring that is screwed in-place.
Thanks in advance,
Wayne
