A few years ago on a forum I used to frequent, A forum member, John (aka Doghouse) did an excellent tutorial on captive rings. John needed a permanent home for the tutorial so I helped him with that.
Welll, I've changed hosting services and have tried to get away from web site work since retiring, and the tutorial kinda got lost. I have located all the files and placed them on my current site (which is a mess, I need to work on that):roll:
I have no idea what happened to John, he disappeared from that forum along with others, but he wanted the information available for others to benefit from.
I turned the goblet above using his tutorial and his instructions made it a breeze.
Hopefully this will help others, if so thanks Doghouse, the info is his, not mine.
The tutorial is available here.
Enjoy, if it helps you, post pics of your rings.
Oh, pay attention to the part about sanding before cutting the rings loose, I didn't do as he said and paid for it!:realmad:
