  • Method of manufacturing a scoring board
    Patent number: 5090106
    Abstract: A scoring board is manufactured by modifying standard blind rivets so that the headed shafts are removed, inverted, and trimmed to provide scoring pegs. The usual tubular sleeve of the blind rivet becomes an insert in enlarged holes in the body of the board. These freely receive the pegs to provide wear-proof receptacles for pegs that are enconomically manufactured by a process relating to nail forging.
