Does anyone have plans to build some sort of jig or fixture for sharpening blades to a 30 degree angle?

There are several brands of blade sharpening jigs on market. A simple Google search will reveal this. For that matter, a simple Google search will reveal many of the redundant, easily found questions that are asked repeatedly on this site. Have a good day.

This is a little red neck but it works for a 30° angle when the angle grinder is held level .

I change the blades on the 54" deck of the Husqvarna probably every two weeks ... just for giggles .... I've got 5 sets of blades of the different styles and use a 4½" grinder with various grit flap discs to put a sharp edge on them. Time has demonstrated to me the grind angle is not at all critical.
It's become a sort of hobby to notice the effects of the different lift blades and how they cut.
Yup ... retired with plenty of time and about 5 acres of grass to mow.
The wife uses a Ferris 1500 for a couple of those acres.
