Just finished ring #2 pictured here. Black ash burl. Watched the video at Woodturnerscatalog.com . Used the bushings and they work fine but I will be getting one of the mandrels soon. Just need to figure out which one. Several choices posted here in this thread.
Do a good turn daily!
Les Elm would be a great source for this subject, hopefully, he'll see this posting and post a tutorial on it. If possible, he would be my go to guy for any of the types of turnings we pen turner's turn. But with him being so busy keeping his stock built up, he doesn't have any spare time. He does what he can to help, but I'd love to be a fly on his wall to watch how he does things.
