Really nice scratch 1:6 scale build of a Astra truck. This guy machined all the gears used in the truck himself (using his lathe like a shaper). The model has air-brakes and power steering. It's very cool check it out and the other videos he has on building the parts. Enjoy!

I apologize in advance, if this a duplicate post. I searched to see if someone else posted his models but was unable to find them.
