Mandrel diameters?

[breckjensen]

Hi,

I am about to try turning a larger bowl, say 10-12", and will make a larger mandrel for those larger bowls. But what diameter should that mandrel have?
Has anyone worked out a ratio of optimal mandrel dimensions to bowl width?
How does, "1 inch of mandrel diameter for every 3-4 inches of bowl" sound?


I didn't find the right solution from the internet.
