Hi crydee,

Will the technique mentioned here possibly work for you:

It can be tough to get a good quality corner when trying to kind of do it in only one piece when it is changing in size by a fair amount.

But it may be easier if you focus on sort of getting the broader main corner form first and not worrying about it being smooth quite yet, and then get the "final" smoothness at the end with a fillet, that's basically what that link is trying to do.

Something along those lines where you're getting the corner to be shaped a bit more on its own rather than kind of everything applying pressure all at once if you kind of know what I mean.

Let me know if that still does not give you a good result.
