Question about rings
You can do them so many different ways, just depends on your machinery.
CNC router,lathe, or milling machine. When you get into indexed rings it's ultra important to keep things perfectly round and more importantly when you bore them out to go on the cue, a perfect hole thru them. If you get the hole non concentric with the indexed slots, you'll never get them lined up correctly on the cue. Especially on a chain like Joey showed in his posting. Best bet is to get some instructional aide. It will save you money and possible a finger or two. Remember when you are looking at the instruction, try to figure out why it's being done, not just how it's being done. You need to understand all the mechanics of the process if you are ever going to rise about the amateur level.
Good luck and most importantly enjoy the process, the results will take care of themselves.
