Hi, I have a Cassese CS910 underpinner and am wondering if there is a way I can make it function as a two stage underpinner. I'd like to press the foot pedal and have the clamp actuated and then press again and have it fire the pin. Can I replace the foot pedal with a two stage pedal and get this functionality? The wrist actuated button is difficult to use for me and I'd like to clamp first before pinning to make sure everything is situated right rather than it happening all at once. Thanks for the help!
