The very first block I ever did was on a Bradbury that had a flange that slowly rolled from 90 degrees on the treble end to about 75 degrees at the horn. What possible design reason could there be for making a mold like this? John McKone, RPT St. louis Park, Minnesota (612) 280-8375 mckonejw@skypoint.com
