Finally getting back to this project. I'm working on the spacer ring. I've got it faced on both sides and it's still chucked up in the 3-jaw chuck. I'll bore a 3/4" hole in it before I remove it from the chuck. Then I need to locate it on a mandrel or arbor of some sort to turn the OD concentric with the ID. I have a set of expanding arbors but have never used them. Will one of those work for me to hold the ring for turning the OD? I'll chuck the arbor in an ER-40 collet. I know I'll probably need to take light cuts. I'm not turning to a specific diameter. I just want to get the OD cleaned up and concentric to the ID. I'll make the part it mates to fit whatever the diameter ends up being.
