Great Video Showing Fabrication of The Tesla Model S

A fantastic video showing behind the scenes fabrication and assembly of a Tesla Model S. This makes our new CNC plasma machine look like something out of the Flintstones. The factory and the innovative methods are really cool, leaving me wanting to take a tour of the factory someday.

Custom Duct Transitions For AC Coil

Installing a new AC coil

There are times when installing a new AC coil to existing duct work can be simple and times when the task can be difficult.
