Volvo G990 Grader

Very interesting! I get so used to seeing guys machine all these great models that I forget all about the possibility of laser cutting parts, and welding them together. Seems once you have your parts, the build would go a bit quicker then having to machine everything. You're making excellent progress! Keep it up.

Agreed, although we should not forget that the skill to design something like that in CAD in a cost-effective and functional way is also considerable.
Ideally, you'd still need have some machined/turned parts, like Stefan's axle carriers.

For smaller scales/models, I think you might find that glueing degreased metal offers more than enough strength, especially if you take it into account during design.
