I can half sympathize with you being left handed. I write right handed, play ball and swing a golf club left handed. I can drive nails with either hand, I turn best right handed but swap hands frequently. I guess I'm one of those that can say my right hand doesn't know what my left can do, or something like that.
I just started turning off the end so I'm used to pushing the banjo down the bed and out of the way to sand. Maybe I'll get used to working with it close to the bowl but for now, I slide it off and hang it on this little shelf I made. Please excuse the mess, I've rough turned over a 100 bowls due to abundance of wood provided by storms in a short period of time. (Pic)
When I bring a piece in, it is a half log. I find the center with a big compass then mark the bowl circle. I use the center mark to mark the face plate circle while I'm there. I then measure the radius of the bowl and set the jig pin on the bandsaw. I then drill the hole for the jig pin, mount the half log on the bandsaw jig and cut the bowl out. I then attach my faceplate with 6 350 lb rated hex headed concrete anchor screws 2" long. Years ago, I've stopped the blank from spinning with a catch a few times, never broke a screw or had any issues with a blank coming loose and never use a tail stock with the faceplate. I rough a bowl pretty aggressively.
First pic notice banjo on wall, second pic bowl layout, third bowl cut still on jig, fourth is a roughed in bowl...hope this helps
