There are rules for doing this documented in the ABS standards for example. In general
what you are thinking might handle it under steady loads, but its necessary to remember
that corners like you suggest will develop stress concentrations and flex under cyclical
loads. 1/2 inch is VERY HEAVY. Have a look at the web site graphs of relationships
between thickness, diameter, and length.
