The Standard Model A talking Machine (phonograph) had a unique hub that fit "Standard" records with a hole diameter of about ½ inch. This replacement hub will allow playing the ¼" hole diameter 78 records as well as the original records (with additional adapter).
I found through measurement and trial and error that the hub taper angle appears to be about 6.3 degrees from center.

The original brass hub can be pressed out of the platter and the new 3D printed hub can be glued in place.
