Well, This bowl was my first using the SN2 & I forgot that it needed a dovetail tenon/recess. The tenon broke off & I turned it into a missile. Embarrassed after having to re-chuck it between centers & not running true this prompted a "design modification" hence the present shape. I made a cove in the rim it's not flat & undercut it also. I like the shape How about you guys & gals?
