Thank you. My hollowing system is a shop made capture ring system. I use John Jordan woodturning boring bars in it. If you want a commercially made version Lyle Jamieson woodturning makes a capture ring system.
I built the system but its a capture ring system made from 2 pieces of 1 inch square tubing and some 3/4 inch black pipe steel fittings. The boring bars i use are from John Jordan woodturning. Lyle Jamieson makes a commercial system similar.
