Thanks for the nice comments everybody.  It's appreciated. This unit was a lot of work.

Duck, The slides are typical Movento undermount drawer guides made by Blum. 
They have a mechanism that snaps onto them  "called tip on" that make them push to open along with the soft close feature. 
The small front rod is a synchronization rod that lets both side actuate at the same time so that the latches don't get out of sync with each other. 

There is also a stabilization kit that goes on the back that has a track and gear with a rod that ties them to each other. This keeps both sides tracking the same so that the wide drawer stays straight going in and out.Here is a closer pic of the hardware,  (it's all I got of it). 

Drawers have 1/2" bottoms glued in on all sides,  they're stout enough to hold whatever they put in them.

Thanks again everybody

Figuring out how to do something you have never done is what makes a good challenge.
