Hi Rob
Apologies, I overlooked your question regarding the lathe hieght.
For me, spending most of my days at the lathe it is very important to get the height right. Spending only a few hours a week it is less of an issue unless you suffer with your back.
The thing is, because everything is so variable, tool bevel angles, tool rest height, your hieght and comfortable stance and the diameter of the wood you are turning, everything can be adjusted to achieve a good bevel rubbing cut but that doesn't mean you'll be comfortable doing it!!
A comfortable turner is a happy turner and a happy and comfortable turner makes better work!
