Im fixing to start a restore on a worked spine Boker, and I've never messed with a worked spine before. I normally use greaseless compounds, but I don't see how the buffing wheels will be able to get into all of the file work on the spine, especially without rounding off all the edges. Do you guys usually have to hand sand and polish those parts? Or is there a trick I haven't learned yet? Thanks in advance for your time. Blake
