[AT] repairing machined tractor parts

[Greg Hass]

Two or three years ago I happened to see the show Jay Leno's Garage. He 
had the upper thermostat housing and the end where the radiator hose 
connected from some rare old car where new or used parts didn't exist. 
The part was broke and could not be fixed. They glued it together, it 
only had to hold itself, and put in a cabinet with a 3D camera. As the 
part turned the camera took pictures. They then used a 3D printer to 
make a plastic part of the housing. In turn they used the plastic part 
to make a foundry mold and then poured it and had an exact part. I'm 
sure there were other steps involved but you get the idea. Was this way 
economical? With Jay Leno I doubt if that entered the picture.
