Ages ago International Billiards in Houston, was looking for a solution to make fixing house cue tips and ferrules easier. This machine would cut the tenon for an interesting ferrule design, and the tip had a tenon on the bottom that would be tapped into the ferrule. No glue was needed. The tips were made of a hard rubber material and would not hold chalk very well.....hence.........the invention of the BRAD scuffer.
The machine, tip, and ferrule idea didn't make it........however...the Brad scuffer became an instant hit.
