I just watched this video, it's long 20 minutes. In fact I've watched it twice. I think I'm just gonna sell the tools and find a new hobby.
Short story, this guy Fred Heim builds 1/2 scale wooden models. Now your probably thinking so, well it's not only the scale, but what he builds models of. How a Peterbuilt 379, pulling a Rogers tri axle equipment trailer. Of course you need a load, how about a Cat D8H, or a 385 excavator, or maybe a wheel loader? Of course with all that dirt moving equipment you gotta have a dump trailer.
The Pete has a little diesel engine. Fred says he can squeeze in it, the wheel loader is remote control.
