Just what I needed
I bought the lap machine knob for my old Gryphon Lapidary Workshop flat lap that was missing the knob. It works like a charm! I also really appreciated how helpful customer support has been answering all my lapidary questions and helping me find the right products.
I'm unsure why the knob comes with two rubber washers though. Is it just a spare?
