Hedge trimmer

This is a strange one: it is not your ordinary machine you would expect here. While I'm waiting for my stepper motor to arrive so I can complete my work on the CNC Router, I thought I show you my other project. I have a Garden with long hedges which needs trimming. This is an tiring affair so I build a machine that helps me to trimm the Hedges straight and without lifting the heavy tool all the time. So far it is for a horizontal cut only. A Arduino is built in and will later be used to auto adjust the height of the trimming and maybe even the trimming pattern - will see.
While most of the frame is made of wood, it uses V-Slot and lots of other parts from the http://openbuildspartstore.com/ so I think it is justified to show it here.
