Can anyone explain the bearing edge lingo being used by Mapex for their new Panther snare lines? Some of the snare list bearing edges as "5:1, 9:2"--stuff like that. What does this mean? How does it translate to a degree-based edge?
I might be wrong but I think it refers to the angle of the bearing in ratio form, just like gradient markers for roads, so for example 9:2 might mean for the bearing every 9mm of in of thickness it has 2mm in height. It's basically a fancy way of expressing the angle of the bearing edge.
