Volvo G990 Grader

[Stefan]

Hello all,

Finally I got the time to start the already promised thread about my grader build. Having started the planning in 2005 this is already a long time project bound to take still quite some years to finish. So expect some frequent postings until I catch up with the present state of things and thereafter... hmm, you´ll probably need some patience *. Anyway, here some basic model data:

Edit: Sorry to say, the picture links in posts #1 to #263 have been broken due to a takeover of the cloud service provider . I managed to save the pics to another, hopefully more reliable provider, but the work to repair the links turns out to be very tedious, and will take quite some time.
