For those of you that TBC, what size tool rest do you use? Because of the shape of my dead and live centers I can't get my tool rest close enough to the piece that I'm turning. Because I'm not using any bushings the distance between the centers is basically the length of whatever tube I'm turning. I'm planning to order a new tool rest from Rick, but it seems like a waste to order a 2" tool rest. However, much longer than that I won't be able to get close enough when turning one barrel from a two barrel pen. Suggestions?
