Does anyone know if any jaw pieces (4) are available that might fit onto my Barricuda 4 (Penn State) chuck that would allow me to cut & 'grab' a 5~6" tenon? (Without having to just grab at the 'points'). Some jaws pieces and be similar.... I saw Mike Mahoney in Nashville last weekend... (he was great as usual). He enlightened me to his method of a wee (1/4") tenon on his larger pieces and I wish to try.. Any reply is appreciated! Happy Turning to all.
