Question on setting up side geometry

In your video for setting up side geometry, towards the end of working the top you use a dish to create the 1-1/2 degree angle at the fretboard extension (after using the 28’ dish). Do you do this with the flat dish or the 28’?
I assume it’s the flat

The 28' radius will give an angle very close to what is needed. I use the 28 foot radius dish or a 30' dish. To avoid the angle being too steep I radius and then flatten the center of the transverse brace.
There is an alternative methods where the upper bout is shimmed up and a flat dish is used to sand in the angle. An important point is not to mix and match procedures or life can get very confusing.
