Good evening my name is Dave Dolan and I am new to the forum. I am looking to add a vacuum chuck to my VB36. It's an older model built in England so the hand wheel is not threaded. My query is has anyone used the One Way system or the Harrison Specialties system? Kerry at Harrison is willing to build me a longer chuck to fit. the One Way is always a good choice but it's piling on the cash to get there. Any feedback?
