If you do not have a Rockler or WoodCraft nearby, but maybe a nice woodworking store, try that. We have a small wood store / mill shop in our town and they teach all kinds of classes.
Also, I've learned a lot from watching You Tube videos on turning. You just need to search with a few key words to find all kinds of lathe tutorials.
Finally, if all else fails,you could buy a book from Amazon! :biggrin: ( I actally own several books on turning, and several books on pen making. Sometimes there is nothing like flipping the pages of a book.)
