I own a small collection of Golden Age (1938 - 1949) jukeboxes all which play shellac 78 records. The jukebox hobby got me into collecting shellac 78's. I mostly collect big band and 50's eras. Some of the famous jukebox hits like Patsy Cline's "Crazy" were never released on shellac so I started thinking whether it would be possible to cut my own. My research led me to this amazing forum. I am a DIYer and I would like to attempt to build a cutting machine. I'm capable when it comes to CNC projects, processors, and electronics but I am a newbie when it comes to mono cutting head designing and building. All my jukes use 3mil sapphire styli so I researched grove dimensions and came up with this:
- groove depth 3mil
groove width 6 to 7mil
groove angle 84 to 88 degrees
groove spacing 100 groves/inch
Thanks,
Scott
