Volvo G990 Grader

@ Paul, Ap, Pontiacmann: Thanks! Glad you like it.

Now to the moldboard. Started from a stainless tube with 3 mm wall thickness. The radius of the tube was only slightly smaller than needed and to my luck it widened up to almost exact scale radius when the cut released the inner tensions.



The upper edge has a non-radiused portion, so a 10 mm by 3 mm strip was added.






The real moldboard is recessed along three sides for the cutting edges as you can see here.




The recesses are apparently forged in a big press, so forging was one of the build options considered, but in the end I opted for a combination of adding parts to the edges and milling and grinding out the final shape. First, the ends were bevelled.
