One of the decisions on which lathe to buy is do you want a long bed or short bed lathe. The sliding headstocks, or the pivoting ones allow you to take a long bed lathe and make it a short bed lathe. This is very handy for bowl turning. That was the reason I picked up a 3520A when they first were available. The Oneway is a long bed lathe. You can turn bowls outboard on it though. Main reason for me to avoid the long bed lathes is I don't care for turning bowls on a long bed lathe set up. You have to hold your arms out away from your body, or bend over, neither of which I like. Slide the headstock down to the end of the lathe and you can stand up straight, and keep your arms in close to your body.
