Well, I started to make my purchase of a vacuum chuck adapter & hub from JTTurningTools at the end of January. Today, I finally got my vacuum adapter kit.. What's that- about 3 months? As I reported Tom Steyer (owner/proprietor) has been having health issues and I believe he continues to fight for a full recovery to this day. I was patient and understanding and it paid off big time. What a really nice setup for vacuum chucking. Thanks to David Roseman's review ( https://sawmillcreek.org/showthread....6-(and-others) ) for inspiring me to go this route. So if you considering any of JTTurnTools products, don't give up. Just call him, and keep calling him until you get through. I wish Tom a full recovery from his ailments. Let's keep supporting the small businesses that make woodturning great!
